Sulfonamide based pyrimidine derivatives combating Plasmodium parasite by inhibiting falcipains-2 and falcipains-3 as antimalarial agents.

In this report, we present the design and synthesis of a novel series of pyrimidine-tethered spirochromane-based sulfonamide derivatives aimed at combating drug resistance in malaria. The antimalarial effectiveness of these compounds was assessed in vitro. Structural validation of the synthesized compounds was conducted using mass spectrometry and NMR spectroscopy. Strong antimalarial activity against CQ-sensitive (3D7) and CQ-resistant (W2) strains of Plasmodium falciparum was demonstrated by the majority of the compounds. Notably, compounds SZ14 and SZ9 demonstrated particularly potent effects, with compound SZ14 showing IC50 values of 2.84 µM and SZ9 3.22 µM, indicating single-digit micromolar activity. The compounds exhibiting strong antimalarial activity were assessed through enzymatic tests against the cysteine protease enzymes of P. falciparum, falcipain-2 and falcipain-3. The results indicated that SZ14 and SZ9 inhibited PfFP-2 (IC50 values: 4.1 and 5.4 µM, respectively), and PfFP-3 (IC50 values: 4.9 and 6.3 µM, respectively). To confirm the compounds' specificity towards the parasite, we investigated their cytotoxicity against Vero cell lines, revealing strong selectivity indices and no significant cytotoxic effects. Additionally, in vitro hemolysis testing showed these compounds to be non-toxic to normal human blood cells. Moreover, predicted in silico ADME parameters and physiochemical characteristics demonstrated the drug-likeness of the synthetic compounds. These collective findings suggest that sulfonamide derivatives based on pyrimidine-tethered oxospirochromane could serve as templates for the future development of potential antimalarial drugs.

Novel Strategy of Training the Accredited Social Health Activists via Application-Based Telemedicine for Cervical Cancer Screening by Human Papillomavirus Self-Sampling: The TRACK Study.

PURPOSE: This pilot study is aimed to analyze a novel strategy of cervical cancer screening by training of Accredited Social Health Activist (ASHA) workers via telemedicine to counsel women for human papillomavirus (HPV) self-sampling. MATERIALS AND METHODS: This is a pilot, community-based, prospective, single-arm study. Physicians trained the ASHA workers regarding self-sampled HPV testing via a mobile application and telephonically using videos and e-pamphlets, who in turn trained the clients in community. The HPV kits were transported via prepaid courier service. RESULTS: Four hundred and sixty-five women of age group 30-65 years were tested by 47 teletrained ASHA workers. The mean age of ASHA worker and clients was 39.47 ± 6.45 and 37.26 ± 8.38 years, respectively. Of the ASHA workers, 91.7% were satisfied with the information provided during telecounseling, 95.7% could understand the contents of mobile app easily, and 93.6% could fill the data of clients in app easily. Of the clients, 99.6% were satisfied with counseling by ASHA workers and 98% found it easy to self-sample. The acceptability of this strategy among clients was 58.2%. The feasibility of this strategy (percentage of clients who find it easy/those who did self-sampling) was around 99%. Among those screened, 11.8% were high-risk HPV-positive and 85.5% had follow-up at the study center. CONCLUSION: The current study highlights a novel strategy of cervical cancer screening by incorporating the role of telemedicine in training ASHA workers and their role in improving the screening by home-based delivery of HPV kits with promising results.

Robust leishmanicidal upshot of some new diphenyl triazine-based molecules.

Amongst the neglected tropical diseases, leishmaniasis alone causes 30 000 deaths annually due to the protozoan parasite genus Leishmania. Existing therapies have serious drawbacks in safety, drug resistance, field-adapted application and cost. Therefore, new safer and shorter treatments are an urgent need of the time. Herein, we report the synthesis of fifteen novel diphenyl triazine and diphenyl triazine pyrimidine derivatives and their antileishmanial properties against Leishmania donovani, that causes fatal visceral leishmaniasis. Most of the synthesized analogues exhibited more than 90% inhibition against the promastigote stage of the parasite. Moreover, compounds T4 and T7 showed potent activity against extracellular promastigote (IC50 = 1.074 µM and IC50 = 1.158 µM) as compared to miltefosine (IC50 = 1.477 µM) and is nontoxic towards the host THP-1 macrophage cell line. Interestingly, compound T4 exhibited significant activity against amastigotes (7.186 µM) and induced the macrophages to prevent the survival of the parasite. Our results indicate that T4 represents a new structural lead for this serious and neglected disease.

Co-Twin Prognosis After Single Intrauterine Fetal Death at a Tertiary Care Hospital in India: A Retrospective Observational Study.

INTRODUCTION: Twin pregnancy is associated with an increased risk of perinatal morbidity. Besides, if intrauterine death of a single twin occurs, it increases the morbidity of the surviving co-twin perinatally and postnatally. AIM:  The objective of this study was to determine the incidence of single intrauterine fetal death (SIUFD) in a twin pregnancy and fetal outcome defined in dimensions according to the complications in the surviving co-twin. MATERIAL AND METHODS: Data on twin pregnancies were collected retrospectively for a period of five years (from 2015 to 2019) from the labour room records of the Central Records Department (CRD) at the Postgraduate Institute of Medical Education and Research, Chandigarh, India. Cases with SIUFD were studied individually and neonatal follow-up was taken post delivery for up to three to eight years. Inclusion criteria were SIUFD in twin pregnancies after 14 weeks gestation, chorionicity pre-defined by early trimester ultrasonography. Exclusion criteria were higher-order pregnancy and monoamniotic twins. RESULTS: A total of 1246 (4.273%) twin deliveries were conducted in the study period. Of these, 107 (8.587%) pregnancies had SIUFD with co-twin surviving in utero. Among these, 77 (72%) were dichorionic diamniotic (DCDA) twin pregnancies and 30 (28%) were monochorionic diamniotic (MCDA) twin pregnancies. The incidence of SIUFD was 8.5%. Preterm birth was the most common complication observed in our study and was found in 53.5% and 58.3% of participants in DCDA and MCDA twins, respectively. Early neonatal death (within 24 hours of life) of the surviving twin was found in 29.2% monochorionic twins with SIUFD. SIUFD at < 28 weeks gestation led to a greater number of early neonatal deaths of surviving twins. The incidence of neurodevelopmental disorders (cerebral palsy, developmental delay, epilepsy) in our population after birth was 7.5% (n=93). CONCLUSION: Twin pregnancies with SIUFD have an increased incidence of preterm labour, increased neonatal death of the surviving twin, and neurodevelopmental disorders (cerebral palsy, developmental delay, epilepsy). Monochorionicity and SIUFD at <28 weeks gestation are associated with increased neonatal deaths in co-twin. The Incidence of neurodevelopmental disorders is not directly associated with chorionicity, but developmental delay is more profoundly seen in the monochorionic group.

Stump Ectopic Pregnancy: A Rare Presentation.

Ectopic pregnancy is a significant cause of maternal morbidity and mortality in women of reproductive age group. Tubal ectopic in an unstable patient is a medical emergency. Tubal stump ectopic is a rare presentation. It is difficult to diagnose. Early diagnosis can prevent significant morbidity and mortality. Here, we present a case of ruptured tubal stump ectopic pregnancy in a 33-year-old female who had undergone salpingectomy previously for ectopic pregnancy.

Autism risk gene Cul3 alters neuronal morphology via caspase-3 activity in mouse hippocampal neurons.

Autism Spectrum Disorders (ASDs) are neurodevelopmental disorders (NDDs) in which children display differences in social interaction/communication and repetitive stereotyped behaviors along with variable associated features. Cul3, a gene linked to ASD, encodes CUL3 (CULLIN-3), a protein that serves as a key component of a ubiquitin ligase complex with unclear function in neurons. Cul3 homozygous deletion in mice is embryonic lethal; thus, we examine the role of Cul3 deletion in early synapse development and neuronal morphology in hippocampal primary neuronal cultures. Homozygous deletion of Cul3 significantly decreased dendritic complexity and dendritic length, as well as axon formation. Synaptic spine density significantly increased, mainly in thin and stubby spines along with decreased average spine volume in Cul3 knockouts. Both heterozygous and homozygous knockout of Cul3 caused significant reductions in the density and colocalization of gephyrin/vGAT puncta, providing evidence of decreased inhibitory synapse number, while excitatory synaptic puncta vGulT1/PSD95 density remained unchanged. Based on previous studies implicating elevated caspase-3 after Cul3 deletion, we demonstrated increased caspase-3 in our neuronal cultures and decreased neuronal cell viability. We then examined the efficacy of the caspase-3 inhibitor Z-DEVD-FMK to rescue the decrease in neuronal cell viability, demonstrating reversal of the cell viability phenotype with caspase-3 inhibition. Studies have also implicated caspase-3 in neuronal morphological changes. We found that caspase-3 inhibition largely reversed the dendrite, axon, and spine morphological changes along with the inhibitory synaptic puncta changes. Overall, these data provide additional evidence that Cul3 regulates the formation or maintenance of cell morphology, GABAergic synaptic puncta, and neuronal viability in developing hippocampal neurons in culture.

Physico-Chemical and Rheological Trait-Based Identification of Indian Wheat Varieties Suitable for Different End-Uses.

India has increased its wheat production phenomenally in the last two decades and it now has a buffer stock of 9.7 million tonnes. However, despite the release of several wheat cultivars, the end-use quality traits of Indian wheat varieties have not been explored in-depth to determine the increasing demand of the domestic processing industry as well as export. In this study, 55 wheat genotypes including 47 released varieties, and 8 genetic stocks were grown along with 10 Australian varieties grown during cropping seasons: 2019-2020 and 2020-2021 and diversity in different physiochemical and rheological traits was evaluated. They showed considerable diversity in all the quality traits studied. However, very few genotypes could be found suitable for any one end-use. Five genotypes were found to possess four to five traits for superior bread-making quality. Two varieties and three advanced breeding lines had up to four good chapati quality traits. None of the released varieties investigated had suitable traits for biscuit making; however, two breeding lines possessed requisite quality traits suitable for biscuit making. It is, therefore, concluded that systematic breeding efforts are required to develop genotypes that bring together the most important quality traits in a single genotype to be suitable for domestic industry as well as for export.

Clinical Profile of Triple-Negative Breast Cancer: A Hospital-Based Study.

Introduction Triple-negative breast cancer (TNBC) is a new concept and an important area of investigation. In Western country's literature, different studies reported on TNBC and all indicated the poor prognostic aspect of this molecular subtype over other types of breast cancer. However, there is a scarcity of comprehensive data from India. Hence, the present study was carried out to look at the epidemiological and clinical characteristics of TNBC in the Indian population. Methods The present study was performed between January 2020 and June 2021 at a tertiary care hospital in Eastern India. A total of 150 patients with TNBC were enrolled in the study. The epidemiological and clinical features of enrolled patients were collected and reviewed. Results The median age of patients at TNBC presentation was 45.53 years (24 to 74 years). The median tumor size was reported to be 5.32 cm. Of 150 patients, 94(62.67%) showed enlarged lymph nodes and 56 (37.33%) patients had no lymph node enlargement. In the present study, 85 (56.67%) patients were in the pre/perimenopausal stage at presentation, whereas 65 (43.33%) patients were in the postmenopausal stage. Upon evaluating the spread of TNBC, it was observed that a maximum of patients 60 (40%) were at the T4 stage and 56 (37.33%) at the N0 condition. The clinical staging of TNBC reported a maximum of 74 (49.33%) patients at the IIA, and IIB stages followed by 53 (35.33%) patients at the IIIA, IIIB, and IIIC stages and a minimum of 11 (7.33%) patients at stage IV. Only five (3.33%) patients were reported with a family history of breast cancer. Of all patients, 126 (84%) had detected early breast cancer thereby applicable for surgery at the time of presentation, whereas 71 (47.33%) patients were eligible for radiation therapy and 138 (92%) patients received chemotherapy. A total of 112 (74.67%) patients were found alive after 24 months of follow-up, 22 (4.67%) patients were observed with remission, and 11 (7.33%) patients died due to TNBC progression. During the course of follow-up, five (3.33%) patients were lost in the study.  Conclusion TNBC is an aggressive malignancy that has a high risk of systemic relapses in the first two years after diagnosis. For more mature evidence on TNBC, longer follow-up of patients is necessary.

Role of Cerebroplacental Ratio in Predicting Perinatal Outcome.

Objective Doppler velocimetry provides a sensitive, non-invasive, and safe method of surveillance of fetal hemodynamics and fetomaternal circulation. Cerebroplacental ratio (CPR) is an indicator of placental function and fetal maladaptation to placental insufficiency. Cerebroplacental ratio (CPR) is becoming a significant indicator of unfavorable pregnancy outcomes, which has implications for the assessment of fetal well-being. This study aimed to determine the cut-off value of the cerebroplacental ratio (CPR) in appropriate for gestational age (AGA) fetuses in high-risk mothers to predict adverse perinatal outcomes. We also compared the efficacy of CPR, umbilical artery pulsatility index (UmA PI), and middle cerebral artery pulsatility index (MCA PI) for predicting adverse perinatal outcomes. Design and setting This was a prospective observational study conducted at the Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, India. Methods A total of 100 women with singleton high-risk pregnancies were included in this prospective observational study. Obstetric ultrasound was performed at the time of recruitment, and fetal weight and CPR were noted. Based on fetal weight, patients were divided into AGA and fetal growth restriction (FGR) groups; CPR was measured; patients were followed up fortnightly; and outcomes were noted. Main outcome The effectiveness of CPR, UmA PI, and MCA PI for predicting poor perinatal outcomes and identifying the cut-off value of CPR in appropriate for gestational age (AGA) fetuses in high-risk mothers was assessed. Result The values of MCA PI, UmA PI, and CPR were statistically significant between AGA and FGR (p-value =.023, .002 and .0001), respectively. The cut-off value for CPR-detecting adverse outcomes in AGA was 1.49. It has sensitivity, specificity, positive predictive value, and negative predictive value of 67.5%, 68%, 71.69%, and 70.21%, respectively. Conclusion Cerebroplacental ratio (CPR) reflects both circulatory insufficiency of the placenta and adaptive changes of the middle cerebral artery, indicating an important non-invasive surveillance modality.

Unraveling Links between Chronic Inflammation and Long COVID: Workshop Report.

As COVID-19 continues, an increasing number of patients develop long COVID symptoms varying in severity that last for weeks, months, or longer. Symptoms commonly include lingering loss of smell and taste, hearing loss, extreme fatigue, and "brain fog." Still, persistent cardiovascular and respiratory problems, muscle weakness, and neurologic issues have also been documented. A major problem is the lack of clear guidelines for diagnosing long COVID. Although some studies suggest that long COVID is due to prolonged inflammation after SARS-CoV-2 infection, the underlying mechanisms remain unclear. The broad range of COVID-19's bodily effects and responses after initial viral infection are also poorly understood. This workshop brought together multidisciplinary experts to showcase and discuss the latest research on long COVID and chronic inflammation that might be associated with the persistent sequelae following COVID-19 infection.

Assessing feasibility of sewage sludge composting in rotary drum reactor.

In a year-long study, the efficacy of a manually operated rotary drum prototype, jointly developed by CEIT Spain and IIM Mumbai, was examined for sanitized compost production in Indian conditions. The prototype, a 200-liter horizontal plastic drum made of high-density polyethylene, incorporated a perforated polypropylene pipe for passive aeration of the composting mixture. Focused on optimizing composting of sewage sludge from a Municipal MBBR, the research targeted key process variables in the rotary drum reactor to attain the thermophilic phase. Wood shavings emerged as the optimal bulking agent, with a mixing ratio of three parts dewatered sewage sludge to one-part bulking agent. A turning frequency of every 12 h proved optimal for achieving the desired temperature of around 60 °C. The study concluded that the final sludge quality met prescribed standards, showcasing the viability of the rotary drum system for efficient compost production in Indian settings.

Unlocking the potential of ancient hexaploid Indian dwarf wheat, Tritium sphaerococcum for grain quality improvement.

Wild and ancient wheat are considered to be a rich source of nutrients and better stress tolerant, hence being re-considered for mainstreaming its cultivation by the farmers and bringing it back to the food basket. In the present study, thirty-four diverse accessions of Indian dwarf wheat, Triticum sphaerococcum conserved in the Indian National Genebank were evaluated for thirteen-grain quality parameters namely thousand-grain weight (TGW), hectolitre weight (HW), sedimentation value (Sed), grain hardness index (HI), protein (Pro), albumin (Alb), globulin (Glo), gliadin (Gli), glutenin (Glu), gluten, lysine (Lys), Fe2+ and Zn2+ content, and four antioxidant enzymes activities. Substantial variations were recorded for studied traits. TGW, HW, Sed, HI, Pro, Alb, Glo, Gli, Glu, Gluten, Lys, Fe2+, and Zn2+ varied from 26.50-45.55 g, 70.50-86.00 kg/hl, 24.00-38.00 ml, 40.49-104.90, 15.34-19.35%, 17.60-40.31 mg/g, 10.75-16.56 mg/g, 26.35-44.94 mg/g, 24.47-39.56 mg/g, 55.33-75.06 mg/g, 0.04-0.29%, 42.72-90.72 ppm, and 11.45-25.70 ppm, respectively. Among antioxidants, peroxidase (POX), catalase (CAT), glutathione reductase (GR), and superoxide dismutase (SOD) activity ranged from 0.06-0.60 unit/ml, 0.02-0.61 unit/ml, 0.11-2.26 unit/ml, and 0.14-0.97 unit/ml, respectively. Hardness Index was positively associated with Pro and Zn2+ content whereas Lys was negatively associated with gluten content. Likewise, gluten and Fe2+ content had a positive association with the major protein fraction i.e., Gli and Glu. Hierarchical cluster analysis grouped 34 accessions into four clusters and the major group had nine indigenous and eight exotic accessions. We also validated high GPC accessions and EC182958 (17.16%), EC187176 and EC182945 (16.16%), EC613057 (15.79%), IC634028 (15.72%) and IC533826 (15.01%) were confirmed with more than 15% GPC. Also, superior trait-specific accessions namely, EC187167, IC534021, EC613055, EC180066, and EC182959 for low gluten content and IC384530, EC313761, EC180063, IC397363, EC10494 for high iron content (>76.51) were identified that may be used in wheat quality improvement for nutritional security of mankind.

Effects of heterozygous deletion of autism-related gene Cullin-3 in mice.

Autism Spectrum Disorder (ASD) is a developmental disorder in which children display repetitive behavior, restricted range of interests, and atypical social interaction and communication. CUL3, coding for a Cullin family scaffold protein mediating assembly of ubiquitin ligase complexes through BTB domain substrate-recruiting adaptors, has been identified as a high-risk gene for autism. Although complete knockout of Cul3 results in embryonic lethality, Cul3 heterozygous mice have reduced CUL3 protein, demonstrate comparable body weight, and display minimal behavioral differences including decreased spatial object recognition memory. In measures of reciprocal social interaction, Cul3 heterozygous mice behaved similarly to their wild-type littermates. In area CA1 of hippocampus, reduction of Cul3 significantly increased mEPSC frequency but not amplitude nor baseline evoked synaptic transmission or paired-pulse ratio. Sholl and spine analysis data suggest there is a small yet significant difference in CA1 pyramidal neuron dendritic branching and stubby spine density. Unbiased proteomic analysis of Cul3 heterozygous brain tissue revealed dysregulation of various cytoskeletal organization proteins, among others. Overall, our results suggest that Cul3 heterozygous deletion impairs spatial object recognition memory, alters cytoskeletal organization proteins, but does not cause major hippocampal neuronal morphology, functional, or behavioral abnormalities in adult global Cul3 heterozygous mice.

Primary leiomyosarcoma of the vulva - a rare occurrence.

Vulval tumours are rare, representing merely 4% of all gynaecological neoplasms. 98% of vulvar lesions are benign, and only 2% are malignant. Of all vulvar malignancies, while squamous cell carcinoma is the most common malignancy, leiomyosarcomas of the vulva are extremely rare. Usually these tumours have nonspecific clinical manifestations, often leading to misdiagnoses of Bartholin cysts or abscesses. We describe a case of a 47-year-old woman who presented with a nonspecific painless swelling in the left vulva for 2 months which was diagnosed as leiomyosarcoma of the vulva on biopsy as well as resection.

G-quadruplex formation at human DAT1 gene promoter: Effect of cytosine methylation.

The dopamine transporter gene (DAT1), a recognized genetic risk factor for attention deficit hyperactivity disorder (ADHD) is principally responsible for the regulation of dopamine synaptic levels and serves as a key target in many psychostimulants drugs. DAT1 gene methylation has been considered an epigenetic marker in ADHD. The identification of G-rich sequence motifs potential to form G-quadruplexes is correlated with functionally important genomic regions. Herein, biophysical and biochemical techniques are employed to investigate the structural polymorphism along with the effect of cytosine methylation on a 26-nt G-rich sequence present in the promoter region of the DAT1 gene. The gel electrophoresis, circular dichroism spectroscopy, and UV-thermal melting data are well correlated and conclude the formation of a parallel (bimolecular), as well as antiparallel (tetramolecular) G-quadruplex in Na+ solution. Interestingly, the existence of uni-, bi-, tri-, and tetramolecular quadruplex structures in K+ solution exhibited only the parallel type G-quadruplex. The results demonstrate that in presence of either cation (Na+ or K+) the cytosine methylation reserved the structural topologies unaltered. However, methylation lowers the thermal stability of G-quadruplexes and the duplex structures, as well. These findings provide insights to understand the regulatory mechanisms underlying the formation of the G-quadruplex structure induced by DNA methylation.

Lipid mediated brain disorders: A perspective.

The brain, one of the most resilient organs of the body is highly enriched in lipid content, suggesting the essential role of lipids in brain physiological activities. Lipids constitute an important structural part of the brain and act as a rich source of metabolic energy. Besides, lipids in their bioactive form (known as bioactive lipids) play an essential signaling and regulatory role, facilitating neurogenesis, synaptogenesis, and cell-cell communication. Brain lipid metabolism is thus a tightly regulated process. Any alteration/dysregulation of lipid metabolism greatly impact brain health and activity. Moreover, since central nervous system (CNS) is the most metabolically active system and lacks an efficient antioxidative defence system, it acts as a hub for the production of reactive oxygen species (ROS) and subsequent lipid peroxidation. These peroxidation events are reported during pathological changes such as neuronal tissue injury and inflammation. Present review is a modest attempt to gain insights into the role of dysregulated bioactive lipid levels and lipid oxidation status in the pathogenesis and progression of neurodegenerative disorders. This may open up new avenues exploiting lipids as the therapeutic targets for improving brain health, and treatment of nervous system disorders.

Multispectroscopic studies of binding interaction of phosmet with bovine hemoglobin.

Phosmet is a phthalimide derived broad spectrum organophosphate pesticide which is vastly used across the globe to protect several ornamental or horticulture crops. The toxicity of phosmet is of utmost concern because of its direct effect on the nervous system of the victim after exposure. The mechanism of phosmet toxicity was explored by the interaction with the model blood protein which is hemoglobin. Bovine Hemoglobin (BHb) is a major protein of red blood cells (RBCs) that plays an important role in the exchange of gases for respiration and ensures adequate oxygen supply to tissues for oxygenation. In the current study, the interaction of BHb with phosmet was revealed using various spectroscopic techniques. Circular dichroism (CD) and Fourier transform infrared spectroscopy (FTIR) studies of BHb in the presence of phosmet showed secondary structural changes in the protein post binding, Fluorescence study shows the involvement of the dynamic quenching predominantly, Van't Hoffs thermodynamic study showed negative enthalpy value and free energy change and negative entropy change that revealed the involvement of hydrogen bonding and van der Waal forces predominantly further revealing spontaneous nature of binding interaction. The shift in Ultraviolet-visible spectra also revealed the nature of the interaction. In-silico study finally deduced the involvement of hydrogen bonding and polar interaction. The study inferred the moderate interaction of BHb with phosmet.

Mapping QTL for Phenological and Grain-Related Traits in a Mapping Population Derived from High-Zinc-Biofortified Wheat.

Genomic regions governing days to heading (DH), days to maturity (DM), plant height (PH), thousand-kernel weight (TKW), and test weight (TW) were investigated in a set of 190 RILs derived from a cross between a widely cultivated wheat-variety, Kachu (DPW-621-50), and a high-zinc variety, Zinc-Shakti. The RIL population was genotyped using 909 DArTseq markers and phenotyped in three environments. The constructed genetic map had a total genetic length of 4665 cM, with an average marker density of 5.13 cM. A total of thirty-seven novel quantitative trait loci (QTL), including twelve for PH, six for DH, five for DM, eight for TKW and six for TW were identified. A set of 20 stable QTLs associated with the expression of DH, DM, PH, TKW, and TW were identified in two or more environments. Three novel pleiotropic genomic-regions harboring co-localized QTLs governing two or more traits were also identified. In silico analysis revealed that the DArTseq markers were located on important putative candidate genes such as MLO-like protein, Phytochrome, Zinc finger and RING-type, Cytochrome P450 and pentatricopeptide repeat, involved in the regulation of pollen maturity, the photoperiodic modulation of flowering-time, abiotic-stress tolerance, grain-filling duration, thousand-kernel weight, seed morphology, and plant growth and development. The identified novel QTLs, particularly stable and co-localized QTLs, will be validated to estimate their effects in different genetic backgrounds for subsequent use in marker-assisted selection (MAS).
