A complex receptor locus confers responsiveness to necrosis and ethylene-inducing like peptides in Brassica napus.

Brassica crops are susceptible to diseases which can be mitigated by breeding for resistance. MAMPs (microbe-associated molecular patterns) are conserved molecules of pathogens that elicit host defences known as pattern-triggered immunity (PTI). Necrosis and Ethylene-inducing peptide 1-like proteins (NLPs) are MAMPs found in a wide range of phytopathogens. We studied the response to BcNEP2, a representative NLP from Botrytis cinerea, and showed that it contributes to disease resistance in Brassica napus. To map regions conferring NLP response, we used the production of reactive oxygen species (ROS) induced during PTI across a population of diverse B. napus accessions for associative transcriptomics (AT), and bulk segregant analysis (BSA) on DNA pools created from a cross of NLP-responsive and non-responsive lines. In silico mapping with AT identified two peaks for NLP responsiveness on chromosomes A04 and C05 whereas the BSA identified one peak on A04. BSA delimited the region for NLP-responsiveness to 3 Mbp, containing ~245 genes on the Darmor-bzh reference genome and four co-segregating KASP markers were identified. The same pipeline with the ZS11 genome confirmed the highest-associated region on chromosome A04. Comparative BLAST analysis revealed unannotated clusters of receptor-like protein (RLP) homologues on ZS11 chromosome A04. However, no specific RLP homologue conferring NLP response could be identified. Our results also suggest that BR-SIGNALLING KINASE1 may be involved with modulating the NLP response. Overall, we demonstrate that responsiveness to NLP contributes to disease resistance in B. napus and define the associated genomic location. These results can have practical application in crop improvement.

NETfacts: An integrated intervention at the individual and collective level to treat communities affected by organized violence.

War and crises affect mental health, social attitudes, and cultural norms, which can exacerbate the state of long-term insecurity. With decades of armed conflict, the Democratic Republic of Congo is one example, and violence has become normalized in civilian settings. In this study, we tested the effectiveness of the NETfacts health system, an integrated model of evidence-based individual trauma treatment (Narrative Exposure Therapy [NET]) and a trauma-informed community-based intervention (NETfacts). Alongside changes in mental health outcomes (posttraumatic stress disorder, depression, social disapproval, and shame) we also investigated change in attitudes, including rape myth acceptance, stigmatization of survivors of sexual violence, and skepticism about the reintegration of former combatants. To test whether the additional community intervention is superior to individual NET alone, we implemented a randomized controlled design with six villages and interviewed a sample of 1,066 community members. Our results demonstrate that the NETfacts health system in comparison with NET alone more effectively reduced rape myth acceptance and with it ongoing victimization and perpetration. Community members of the NETfacts group also presented with less stigmatizing attitudes against survivors of sexual violence. Skepticism about the reintegration of former combatants declined in both groups. NETfacts appears to have increased motivation to engage in individual treatment. Synergizing the healing effects of individual and collective trauma exposure, the NETfacts health system appears to be an effective and scalable approach to correct degrading or ignominious norms and restore functioning and mental health in postconflict communities.

Overexpression of oilseed rape trehalose-6-phosphate synthesis gene BnaC02.TPS8 confers sensitivity to low nitrogen and high sucrose-induced anthocyanin accumulation in Arabidopsis.

MAIN CONCLUSION: Overexpression of BnaC02.TPS8 increased low N and high sucrose-induced anthocyanin accumulation. Anthocyanin plays a crucial role in safeguarding photosynthetic tissues against high light, UV radiation, and oxidative stress. Their accumulation is triggered by low nitrogen (N) stress and elevated sucrose levels in Arabidopsis. Trehalose-6-phosphate (T6P) serves as a pivotal signaling molecule, sensing sucrose availability, and carbon (C) metabolism. However, the mechanisms governing the regulation of T6P synthase (TPS) genes responsible for anthocyanin accumulation under conditions of low N and high sucrose remain elusive. In a previous study, we demonstrated the positive impact of a cytoplasm-localized class II TPS protein 'BnaC02.TPS8' on photosynthesis and seed yield improvement in Brassica napus. The present research delves into the biological role of BnaC02.TPS8 in response to low N and high sucrose. Ectopic overexpression of BnaC02.TPS8 in Arabidopsis seedlings resulted in elevated shoot T6P levels under N-sufficient conditions, as well as an increased carbon-to-nitrogen (C/N) ratio, sucrose accumulation, and starch storage under low N conditions. Overexpression of BnaC02.TPS8 in Arabidopsis heightened sensitivity to low N stress and high sucrose levels, accompanied by increased anthocyanin accumulation and upregulation of genes involved in flavonoid biosynthesis and regulation. Metabolic profiling revealed increased levels of intermediate products of carbon metabolism, as well as anthocyanin and flavonoid derivatives in BnaC02.TPS8-overexpressing Arabidopsis plants under low N conditions. Furthermore, yeast two-hybrid (Y2H) and bimolecular fluorescence complementation (BiFC) analyses demonstrated that BnaC02.TPS8 interacts with both BnaC08.TPS9 and BnaA01.TPS10. These findings contribute to our understanding of how TPS8-mediated anthocyanin accumulation is modulated under low N and high sucrose conditions.

Selenium in soil enhances resistance of oilseed rape to Sclerotinia sclerotiorum by optimizing the plant microbiome.

Plants can recruit beneficial microbes to enhance their ability to resist disease. It is well established that selenium is beneficial in plant growth, but its role in mediating microbial disease resistance remains poorly understood. Here, we investigated the correlation between selenium, oilseed rape rhizosphere microbes, and Sclerotinia sclerotiorum. Soil application of 0.5 and 1.0 mg kg-1 selenium [selenate Na2SeO4, Se(VI) or selenite Na2SeO3, Se(IV)] significantly increased the resistance of oilseed rape to Sclerotinia sclerotiorum compared with no selenium application, with a disease inhibition rate higher than 20% in Se(VI)0.5, Se(IV)0.5 and Se(IV)1.0 mg kg-1 treatments. The disease resistance of oilseed rape was related to the presence of rhizosphere microorganisms and beneficial bacteria isolated from the rhizosphere inhibited Sclerotinia stem rot. Burkholderia cepacia and the synthetic community consisting of Bacillus altitudinis, Bacillus megaterium, Bacillus cereus, Bacillus subtilis, Bacillus velezensis, Burkholderia cepacia, and Flavobacterium anhui enhanced plant disease resistance through transcriptional regulation and activation of plant-induced systemic resistance. In addition, inoculation of isolated bacteria optimized the bacterial community structure of leaves and enriched beneficial microorganisms such as Bacillus, Pseudomonas, and Sphingomonas. Bacillus isolated from the leaves were sprayed on detached leaves, and it also performed a significant inhibition effect on Sclerotinia sclerotiorum. Overall, our results indicate that selenium improves plant rhizosphere microorganisms and increase resistance to Sclerotinia sclerotiorum in oilseed rape.

Cytokinin oxidase/dehydrogenase inhibitors: progress towards agricultural practice.

Cytokinin oxidase/dehydrogenase (CKX) inhibitors reduce the degradation of cytokinins in plants and thereby may improve the efficiency of agriculture and plant tissue culture-based practices. Here, we report a synthesis and structure-activity relationship study of novel urea derivatives concerning their CKX inhibitory activity. The most active compounds showed sub-nanomolar IC50 values with maize ZmCKX1, the lowest value yet documented. Other CKX isoforms of maize and Arabidopsis were also inhibited very effectively. The binding mode of four compounds was characterized based on high-resolution crystal complex structures. Using the soil nematode Caenorhabditis elegans, and human skin fibroblasts, key CKX inhibitors with low toxicity were identified. These compounds enhanced the shoot regeneration of Lobelia, Drosera, and Plectranthus, as well as the growth of Arabidopsis and Brassica napus. At the same time, a key compound (identified as 82) activated a cytokinin primary response gene, ARR5:GUS, and a cytokinin sensor, TCSv2:GUS, without activating the Arabidopsis cytokinin receptors AHK3 and AHK4. This strongly implies that the effect of compound 82 is due to the up-regulation of cytokinin signalling. Overall, this study identifies highly effective and easily prepared CKX inhibitors with a low risk of environmental toxicity for further investigation of their potential in agriculture and biotechnology.

Characterization of male sexual assault in the state of São Paulo, Brazil: an epidemiological study from 2014 to 2017.

Sexual violence is a pervasive global issue that affects individuals of all genders. However, the experiences of male survivors have often been marginalized and inadequately represented. Male rape, which encompasses several forms of sexual violence against men, remains a sensitive and under-discussed topic in academic literature and public discourse. This study presents a descriptive cross-sectional analysis based on data collected from the Legal Medicine Institute (IML-São Paulo, Brazil) between 2014 and 2017. The analysis includes 7386 reports of sexological examinations performed on male victims of alleged rape. The analysis reveals that a significant majority of rape reports involved victims under the age of 12 or 14, which is considered vulnerable rape by the Brazilian legislation. Regarding the examination of reported cases of abuse against men, it was observed that only the minority of these cases exhibited visible injuries consistent with rape or tested positive for the presence of spermatozoa in the perianal region. Since the absence of visible injuries or spermatozoa does not negate the possibility of rape, this work highlights the challenges in obtaining conclusive evidence, necessitating a comprehensive approach to investigate and prosecute these crimes, creating a more inclusive and supportive environment for all survivors of rape, irrespective of their gender.

Female perpetrated sexual assault: a review of attendances to the national sexual assault treatment units in the Republic of Ireland.

BACKGROUND: Female perpetrated sexual assault is under-represented in sexual assault research, and indeed possibly an underreported crime. The aim of this study is to address the lack of comprehensive data in relation to female perpetrated sexual assault attendances to the national sexual assault treatment unit network in the Republic of Ireland. METHODS: This is a cross-sectional study analysing the attendances of female perpetrated sexual assault attendances at the six sexual assault treatment units in the Republic of Ireland between 1 January 2017 and 31 December 2022. RESULTS: There were 95 attendances where the assailant (or one of the assailants) was identified as female. 62% (n=59) of these attendances involved a solo female assailant, 3.2% (n=3) where it was a multiple assailant assault with only female assailants and 34.7% (n=33) cases with male and female assailants. 74.7% (n=71) of victims identified as female, 24.2% (n=23) as male and 1.1% (n=1) as 'other'. The average age of attenders was 27.0 ± 10.7 years old. 54.7% (n=52) of attendances were within 72 hours of the assault. 52.6% (n=50) of these underwent a forensic examination. 30.5% (n=29) of incidents occurred in the assailant's home. 23% of assailants were described as a friend of the victim/survivor. 34.7% (n=33) sustained bodily injuries (genital and/or extra-genital). CONCLUSION: Female perpetrated sexual assault is a distinct entity when analysing attendances to the national sexual assault treatment unit network, representing just under 2% of all attendances. We have shown that those who experience these assaults are likely to be female, be assaulted by a single female perpetrator who is known to them and attend a sexual assault treatment unit within 72 hours of the assault. Awareness of the characteristics of these attendances will ultimately allow us to develop appropriate supports for these victims/survivors and to raise awareness of this type of crime.

Development of the Vietnamese Rape Myths Acceptance Scales: A Web-Based Survey of Young Adults.

Rape myths-false but widely held beliefs that serve to deny and justify sexual aggression-present a major barrier to reporting and prevention of sexual violence in Vietnam and globally. Based on a parent study aimed at reducing sexual violence at two universities in Hanoi, we developed and assessed a contextualized measure of rape myths among young people in Vietnam. Items from previously validated rape myth acceptance (RMA) scales and data from qualitative research informed the development of 50 items, which were administered to Vietnamese 18-24-year-olds (n = 2,756 total, n = 1,798 cisgender women) via an anonymous link in February 2021. We used factor analysis to explore and test factor structure and multi-group factor analysis to assess measurement equivalence across gender. We calculated item-level discrimination and difficulty parameters and visualized information curves using item response theory analysis, informing the development of a short form. Four hypothesized subconstructs identified in the qualitative data emerged as factors: (1) "He didn't mean to"; (2) "She asked for it"; (3) "It wasn't really rape"; and (4) "Rape is a deviant event." A fifth factor, "She didn't protect herself," included four items from formative data. Confirming formative findings and prior literature, cisgender women had lower RMA than cisgender men, particularly on items related to victim-blaming. The Vietnamese Rape Myths Acceptance Scales were internally consistent and equivalent between cisgender men and women, capturing elements specific to the Vietnamese context and providing a tool for campus climate surveys and evaluations of sexual violence prevention programs.

"I Think You Covered the Three Levels of Drugs and Consent": Qualitatively Testing Different Operationalizations of an Alcohol and Other Drugs-Involved Sexual Violence.

Substance-involved rape is increasing among college students, particularly women (Koss et al., 2022). Addressing rape requires first measuring it accurately in surveys to understand its true scope and nature. We used cognitive interviews with 40 young adults to qualitatively test the construct validity of an alcohol- and other drugs (AOD)-involved rape item in the Sexual Experiences Survey by asking participants to comment on different operationalizations of this construct. Our findings revealed that different phrasings elicited different interpretations of the items by participants. Specifically, the results indicated that (1) respondents viewed the different operationalizations as a sequence of events with varying severity; (2) some participants focused on the intentionality and responsibility of the perpetrator as opposed to opportunistic perpetration; and (3) study participants consistently chose one of the operationalizations as describing "being roofied" (being drugged without consent). Participants also contributed additional scenarios not described in the questionnaire and shared their interpretations of the items. The results underscore the importance of refining survey language to properly measure AOD-involved rape and allow us to understand how to tailor appropriate questions for best comprehension. The findings indicate the benefit in including several items about AOD-involved rape in questionnaires such as the Sexual Experiences Survey, with each item addressing different scenarios of victim intoxication. The results could also have important implications for sexual violence prevention programs, which should discuss consent, intentions, and responsibility specifically in the context of AOD consumption.

Evidence That Pervasive Body Gaze Behavior in Heterosexual Men Is a Social Marker for Implicit, Physiological, and Explicit Sexual Assault Propensities.

Deliberate and effortful attempts to gaze at the bodies of women is emerging as a valuable marker of sexual objectification in men. Some preliminary evidence suggests that pervasive body gaze behavior may also accompany insidious attitudes which can facilitate sexual assault. The present study aimed to further explore this potential by examining pervasive body gaze associations with explicit, implicit, and physiological sexual assault propensity measures. We presented 110 heterosexual male participants with images of fully and partially dressed women with and without injuries while measuring their skin conductance responses. We also captured implicit and explicit sexual assault measures in addition to self-reported pervasive body gaze behavior. Pervasive body gaze behavior was significantly correlated with rape myth acceptance attitudes, prior perpetration of sexual assault, a stronger implicit association between erotica and aggression, and lower physiological reactivity during exposure to partially dressed injured women. These findings suggest that body gaze towards women could be a behavioral marker for inclinations to victim blame, preferences for rough sexual conduct, and a physiological desensitization towards female victims. This study further validates a five item self-reported body gaze measure as a valuable tool for detecting deviant sexual objectification attitudes and affective states. As such, measurement and observation of body gaze behavior could be useful for developing risk assessments, estimating intervention efficacy, and enhancing public awareness.

Rape or Homicide: Which Is Worse?

Some people believe rape is just as serious as homicide, or more serious, contrary to law. We examined the prevalence of this belief and whether it reflects an individual's political ideology and moral foundations. Analyses were based on a national YouGov survey of 1,125 US adults gathered in 2021. We found that only 26% of respondents believed rape was less serious than homicide. Most (61%) believed rape and homicide were equally serious, while 13% believed rape was more serious. Social progressives (particularly progressive women) were more likely than social conservatives to view rape as more serious or just as serious as homicide. However, this tendency was partially offset by the tendency of social progressives to view harm as a key factor in judging the morality of a behavior. We suggest that social progressives view rape more seriously than social conservatives because of their concern for gender inequality, but this concern is partially offset by their concern with harm.

Characteristics of higher education students who reported sexual violence: a Nigerian national study.

BACKGROUND: Sexual violence among higher education students is a global public health problem. Identifying the characteristics of students who report victimization can serve as basis for programmes that target vulnerable students. METHODS: The study was conducted among 30,114 Nigerian higher education students. They were selected from 18 institutions comprising universities, polytechnics, and colleges of education. The purpose of the study was to assess the characteristics of students who reported sexual violence (rape, attempted rape and sexual harassment) and to determine the association between reporting and their characteristics. RESULTS: Our findings showed that 37% of the students reported experiencing sexual violence. Regression analysis showed that the odds of reporting among female students were two times greater than that of the male students (CI = 1.58-1.78; P < 0.001). The students who were traditionalists (aOR = 2.65, p < 0.001) or from other religious groups (aOR = 3.28, p < 0.001) had higher odds of reporting than those who were Christians. All the age groups represented in the study had significantly higher odds of reporting except those between 25 and 29 years (aOR = 1.03; p = 0.616). Non-final year students had significantly 7% lower odds of reporting (p = 0.037) than the first-year students. The students in the arts and humanities-related programmes significantly had higher odds of reporting than those in the science-related programs (aOR = 1.08; p = 0043). In addition, polytechnic and colleges of education students were two times more likely to report sexual violence than university students (p < 0.001). Also, the students from other regions were two times more likely to report sexual violence than those from Southwest region. CONCLUSION: The study concluded that sexual violence reporting by higher education students differ by their types of schools, sex, religion, level of education and geographical location.

'Displaced in the name of Religion': Girl child abuse and community healthcare workers' response to women crying for help in IDP camps in North Central, Nigeria.

This study examines girl child abuse in an internally displaced people's camp in north-central Nigeria and the response of community health workers. The conflict in Benue State is caused by religious differences between the natives (Tiv people) and the invading Fulani herdsmen. During these conflicts, women and girls were displaced, and they were kept in internally displaced persons (IDPs) located in different parts of the state. Literature has been extensively written on internal displacement in Nigeria, but none has been able to elucidate the health needs of girls and the various abuses girls and women are suffering in IDP camps. In this study, literature was extended (1) to explore the environment of the girl child in IDP camps, (2) to identify reasons for the abuse of the girl child in IDP camps, (3) to investigate the impacts of the abuse on the girl child in IDP camps and (4) to investigate how healthcare workers could be used to alleviate the plight of girl children in IDP camps. This is a qualitative case study, with data obtained from relevant academic literature and personal observation. The data were analysed using content analysis. Findings reveal that the girl child is suffering from psychological, economic and health challenges due to the various forms of abuse they are going through. Following the devastation in Benue State, healthcare workers from the community relocated to neighbouring states. There is a need to recall those healthcare workers and provide them with the necessary materials to assist girls in IDP camps. Recommendations are discussed.

A qualitative study on the health system-related needs in women survivors of rape.

BACKGROUND: Rape, as an adverse incidence, leads to irreparable complications and consequences in women. Provision of health services to women survivors of rape requires catering for their real needs and identifying current deficits as well as barriers. The present study aimed to explore health system-related needs in women survivors of rape. METHODS: In the present qualitative study, the participants consisted of 39 individuals, including 19 women survivors of rape and 20 individuals with work experience in providing services to women survivors of rape. The participants were selected using the purposive sampling method with a maximum variation in Isfahan, Iran. Data were collected through in-depth interviews as well as field notes and were concurrently analyzed via conventional qualitative content analysis method. RESULTS: After analyzing the interviews, the health system-related needs of women survivors of rape were classified into two main categories: 1- The need for efficient medical care services with three sub-categories, namely "receiving services with respect for privacy and confidentiality", "non-judgmental behavior and approach", and "the need to receive empathy and the feeling of not being alone", and 2- The need for desirable conditions and structure to provide services with two sub-categories, namely "the need to receive comprehensive and integrated services", and "establishing specialized centers for providing services to survivors". CONCLUSIONS: Overall, explaining and highlighting the health system-related needs of women survivors of rape could provide a suitable basis for policy-making and planning according to their real needs. Receiving continuous services in separate centers with confidentiality and empathy could reduce the worries and concerns of women survivors of rape and help improve their health.

#WhyIDidntReport my sexual violence and its effect on social support.

An analysis of social media posts using the #WhyIDidntReport hashtag reveals six themes regarding the reasons why survivors of sexual violence do not report the incident to health or social organisations such as police or supervisors. Using just-world theory as a means to examine social reactions to posts of victim's stories, we suggest the reasons for not reporting could be divided into clusters of internal or external barriers. Within the first cluster, three themes reflect survivors who did not report because of external reasons (e.g. victim blaming by the police or other institutions; minimisation of the seriousness of the crime; and reporting costs). In the second cluster, three themes reflect survivors who did not report because of internal reasons (e.g. self-blame, protecting others, and naivety). We find that survivors who did not report sexual violence because of external reasons received significantly more social support, whereas survivors who did not report because of internal reasons received significantly less social support in the form of shares and likes. Overall, these findings support our theorising that the reasons why survivors do not report sexual violence are impactful because, consistent with just-world theorising, they change perceptions of victimhood and therefore the level of social support.

Assessing the impact of Chlorantraniliprole (CAP) pesticide stress on oilseed rape (Brassia campestris L.): Residue dynamics, enzyme activities, and metabolite profiling.

This study investigates the effects of chlorantraniliprole (CAP) pesticide stress on oilseed rape through comprehensive pot experiments. Assessing CAP residue variations in soil and oilseed rape (Brassia campestris L.), enzyme activities (POD, CPR, GST), and differential metabolites, we unveil significant findings. The average CAP residue levels were 18.38-13.70 mg/kg in unplanted soil, 9.94-6.30 mg/kg in planted soil, and 0-4.18 mg/kg in oilseed rape samples, respectively. Soil microbial influences and systemic pesticide translocation into oilseed rape contribute to CAP residue variations. Under the influence of CAP stress, oilseed rape displays escalated enzyme activities (POD, CPR, GST) and manifests 57 differential metabolites. Among these, 32 demonstrate considerable downregulation, mainly impacting amino acids and phenolic compounds, while 25 exhibit noteworthy overexpression, primarily affecting flavonoid compounds. This impact extends to 24 metabolic pathways, notably influencing amide biosynthesis, as well as arginine and proline metabolism. These findings underscore the discernible effects of CAP pesticide stress on oilseed rape.

Variation in Pathogenicity and Subsequent Production of Sclerotia of Sclerotinia sclerotiorum Isolates in Different Cover Crops, Flower Strips, and Weeds.

Cover crops and flower strips are used in agricultural fields as part of integrated pest management strategies. However, their potential as secondary hosts of soilborne pathogens such as Sclerotinia sclerotiorum in oilseed rape cultivation is not fully comprehended. In the current study, we evaluated the effect of pathogen virulence on the development of Sclerotinia stem/leaf rot and sclerotia production in 33 plant species from 11 botanical families using two S. sclerotiorum isolates. Furthermore, the effect of sclerotial size on carpogenic germination was studied. Results showed that the pathogen's virulence significantly affected the occurrence and development of Sclerotinia stem/leaf rot and the subsequent production of sclerotia. Among all plant species tested, 26 were more susceptible to the highly aggressive S. sclerotiorum isolate, which produced more and bigger sclerotia in 17 species than the less aggressive isolate. Moreover, a stronger positive correlation was found between the relative lesion length of plants inoculated with the highly aggressive isolate and the number of sclerotia produced by this isolate (Spearman's rank correlation coefficient [rs] = 0.572; P = 0.004). Additionally, we found that larger and heavier sclerotia produced stipes and apothecia earlier and at a greater rate than smaller ones. The heavyweight class had the highest carpogenic germination rate (82.4%), followed by the average (67.2%) and lightweight classes (59.5%). Our findings highlight the need for further investigation into the potential risks associated with cover crops, weeds, and flower strips as secondary hosts of soilborne pathogens in agricultural fields.

Influence of nanoscale sulfur on mercury accumulation and plant growth in oilseed rape seedlings (Brassica napus L.) grown on mercury-contaminated soil.

Mercury (Hg) pollution has seriously threatened the crop productivity and food security. In the present research, experiments were conducted to assess the influence of nanoscale sulfur/sulfur nanoparticles and the corresponding bulk and ionic sulfur forms on the growth and Hg accumulation of oilseed rape seedlings grown on Hg-contaminated soil, as well as the transformation of soil Hg fractions. The results showed a significant reduction in fresh biomass for seedlings grown on 80-200 mg/kg Hg-polluted soil after 30 days. At 120 mg/kg Hg treatment, 100-300 mg/kg sulfur nanoparticles (SNPs) application counteracted Hg toxicity more effectively compared to the corresponding bulk sulfur particles (BSPs) and ionic sulfur (sulfate) treatments. The seedlings treated with 120 mg/kg Hg + 300 mg/kg SNPs gained 54.2 and 56.9% more shoot and root biomass, respectively, compared to those treated with Hg alone. Meanwhile, 300 mg/kg SNPs application decreased Hg accumulation by 18.9 and 76.5% in shoots and roots, respectively, relative to Hg alone treatment.SNPs treatment caused more Hg to be blocked in the soil and accumulating significantly less Hg in plants as compared to other S forms. The chemical fractions of Hg in the soil were subsequently investigated, and the solubility of Hg was significantly decreased by applying SNPs to the soil. Especially 200-300 mg/kg SNPs treatments caused the ratio of the soluble/exchangeable and the specifically absorbed fraction to be the lowest, accounting for 1.95-4.13% of the total Hg of soil. These findings suggest that adding SNPs to Hg-contaminated soils could be an effective measure for immobilizing soluble Hg and decreasing the Hg concentration in the edible parts of crops. The results of the current study hold promise for the practical application of SNPs to Hg-contaminated farmland for better yields and simultaneously increasing the food safety.

The novelty of this study is the selection of oilseed rape and nanoscale sulfur (NS) or sulfur nanoparticles (SNPs) as nontoxic nanomaterial to counteract the Hg toxicity and accumulation. Oilseed rape was selected due to its wide adaptability to various environmental conditions and the high-value oil for human consumption and biofuels production. These advantages make oilseed rape a highly valuable crop for various applications. NS was selected due to its reported ability to limit the uptake of heavy metals in oilseed rape, rice, and wheat along with other crops and subsequently restrict the toxicity of heavy metals in these plants and improve food safety. In this study, we evaluated the growth, Hg accumulation, and the resulting toxicity in oilseed rape grown on Hg-contaminated soil, with or without amendments with NS. The outcomes from this study provided evidence of the significant potential of NS in preventing Hg bioaccumulation and improving crop yields in oilseed rape. This provides opportunity to use NS as an ideal non-GMO approach to limit toxic metals in crops.

Effects of sulfur nanoparticles on rhizosphere microbial community changes in oilseed rape plantation soil under mercury stress.

In the present study, experiments were conducted to assess the influence of nanoscale sulfur in the microbial community structure of metallophytes in Hg-contaminated rhizosphere soil for planting rapeseed. The results showed that the richness and diversity of the rhizobacteria community decreased significantly under Hg stress, but increased slightly after SNPs addition, with a reduction in the loss of Hg-sensitive microorganisms. Moreover, all changes in the relative abundances of the top ten phyla influenced by Hg treatment were reverted when subjected to Hg + SNPs treatment, except for Myxococcota and Bacteroidota. Similarly, the top five genera, whose relative abundance decreased the most under Hg alone compared to CK, increased by 19.05%-54.66% under Hg + SNPs treatment compared with Hg alone. Furthermore, the relative abundance of Sphingomonas, as one of the dominant genera for both CK and Hg + SNPs treatment, was actively correlated with plant growth. Rhizobacteria, like Pedobacter and Massilia, were significantly decreased under Hg + SNPs and were positively linked to Hg accumulation in plants. This study suggested that SNPs could create a healthier soil microecological environment by reversing the effect of Hg on the relative abundance of microorganisms, thereby assisting microorganisms to remediate heavy metal-contaminated soil and reduce the stress of heavy metals on plants.

In this manuscript, we first comprehensively investigated the changes in the rhizosphere microbial community structure of metallophytes in Hg-contaminated soil with SNPs addition, as well as the relationship between soil microbiology and plant resistance to Hg stress. Our results demonstrated that SNPs exhibit a significant advantage in improving rhizosphere microecology by increasing the abundance of beneficial rhizobacteria, thereby alleviating heavy metal toxicity, and promoting plant growth. This study is the first study describing the response of soil microorganisms coexposed to heavy metals and SNPs, providing valuable information for the potential use of SNPs to assist phytoremediation of toxic metal pollution and its impact on soil microbial communities.

Jurors' perceptions of transgender victims of sexual assault: A literature review of empirical research and policy review of judicial instructions.

Sexual assault affects many people of all gender identities, yet most cases do not result in conviction. This may be due to common, inaccurate misperceptions juries hold about how sexual assault is perpetrated and how victims respond to sexual assault. Research has examined misperceptions relating to cisgender victims, yet little is known about the unique misconceptions and stereotypes that may unfairly disadvantage transgender victims or whether courts are attempting to safeguard against them. This article presents a literature review of empirical research on (mock) jurors' perceptions of transgender victims and a review of judicial instructions about gender identity. We find that empirical research is extremely limited with mixed findings, but many jurisdictions allow for judicial instructions warning jurors against prejudice based on gender identity. Further research is urgently needed to identify common misperceptions jurors may have that are specific to transgender victims to inform legal safeguards and improve justice outcomes.
