Ayurveda for a Type 1 Diabetes Patient with Peripheral Arterial Occlusive Disease: A Case Report.

INTRODUCTION: The effect of Ayurvedic therapy in type 2 diabetes (T2D) is well documented. For people with type 1 diabetes (T1D), there is little evidence on the applicability of Ayurvedic therapy. This case illustrates the course of Ayurvedic treatment in a person with T1D accompanied by peripheral arterial occlusive disease (PAOD). CASE PRESENTATION: The patient had insulin-dependent T1D since the age of 6 years. At 39 years of age, he developed progressive bilateral PAOD of the femoral arteries. He presented claudication symptoms at a walking distance of 150 m. Ten surgical interventions for recanalization have been performed. The PAOD put heavy psychological strains on the patient. He developed moderate depression with anxiety and complained of tinnitus and sleep disturbances. Through an initial outpatient Ayurvedic treatment mainly focused on dietary, lifestyle changes and phytotherapeutics, and a subsequent 6-week inpatient Ayurvedic treatment in India, a weight reduction of 12 kg, a reduction in insulin requirement to 65% of baseline, as well as a walking performance without restriction at a medium load could be achieved. The depression and inner tension retreated, and one-sided tinnitus and existing sleep disturbances dissolved completely. The lasting effect was still perceptible 5 months after the inpatient stay. CONCLUSIONS: For this person with T1D with PAOD, outpatient and inpatient Ayurvedic therapy could generate a significant improvement of his situation. The case demonstrates that people with T1D can benefit from using individualized Ayurvedic therapy. This case motivates to invest in Ayurvedic research for people with T1D and complications.Die Wirkung der ayurvedischen Therapie bei Typ-2-Diabetes (T2D) ist gut dokumentiert. Für Menschen mit Typ-1-Diabetes (T1D) gibt es kaum Belege für die Anwendbarkeit der ayurvedischen Therapie. Dieser Fall veranschaulicht den Verlauf einer ayurvedischen Behandlung bei einer Person mit T1D, begleitet von einer peripheren arteriellen Verschlusskrankheit (pAVK).Der Patient hatte seit seinem 6. Lebensjahr einen insulinabhängigen 'T1D'. Im Alter von 39 Jahren entwickelte er eine fortschreitende bilaterale periphere arterielle Verschlusskrankheit (pAVK) der Oberschenkelarterien. Bei einer Gehstrecke von 150 m zeigte er Claudicatio-Symptome. Es wurden 10 chirurgische Eingriffe zur Rekanalisation durchgeführt. Die pAVK stellte für den Patienten eine starke psychische Belastung dar. Er entwickelte eine mittelschwere Depression mit Angstzuständen und klagte über Tinnitus und Schlafstörungen. Durch eine erste ambulante ayurvedische Behandlung, die sich hauptsächlich auf Ernährungs-, Lebensstiländerungen und Phytotherapeutika konzentrierte, und eine anschließende 6-wöchige stationäre ayurvedische Behandlung in Indien wurde eine Gewichtsreduktion um 12 kg, eine Reduzierung des Insulinbedarfs auf 65% des Ausgangswerts sowie eine bedeutende Verbesserung der Gehstrecke erreicht. Die Depression und die innere Anspannung verschwanden, und der einseitige Tinnitus und bestehende Schlafstörungen lösten sich vollständig auf. Der nachhaltige Effekt war noch 5 Monate nach dem stationären Aufenthalt spürbar.Für diese Person mit T1D mit pAVK konnte eine ambulante und stationäre ayurvedische Therapie eine deutliche Verbesserung der Situation bewirken. Der Fall zeigt, dass Menschen mit T1D von einer individualisierten ayurvedischen Therapie profitieren können. Dieser Fall motiviert dazu, in die ayurvedische Forschung für Menschen mit T1D und Komplikationen zu investieren.

The Introspective Patient Experience of Mistletoe Therapy in Cancer: A Qualitative Study.

INTRODUCTION: The introspective experience of cancer patients using mistletoe therapy has received little scientific interest, although it is crucial for a holistic understanding of this therapy. This study contributes to patient-centered research and treatment by documenting the subjective experiences of individuals undergoing mistletoe therapy. METHODS: In this qualitative, explorative study, 20 outpatients with a history of various cancer types were recruited from Arlesheim Hospital (Arlesheim, Switzerland). All patients received subcutaneous mistletoe therapy for at least 2 years (median 7.5 years). Data was collected through 2 semi-structured, in-depth interviews per patient. Qualitative content analysis was applied to examine the data. The individual experience of mistletoe therapy was analyzed in relation to 6 predefined levels of human experience: physical, vital, emotional, mental, spiritual and social. In addition, 3 further aspects, considered as cross-dimensional perspectives, emerged out of the material: warmth, immune strengthening, and general wellbeing. RESULTS: Data analysis revealed considerable heterogeneity among patients' experiences with mistletoe therapy. The importance of specific aspects became apparent, such as increased vitality to manage daily life, greater emotional and mental stability, warmth as a multidimensional phenomenon, feelings of safety and protection through mistletoe therapy, heightened self-awareness and improved self-care, as well as sensations of spiritual connectedness. CONCLUSIONS: Prior to this study it had not been shown that cancer patients using mistletoe therapy do have observations on different levels of experience. These results may lead to a deeper understanding of patients receiving mistletoe therapy, enabling them to be supported in a more holistic way both during mistletoe treatment and on their life path. Further investigations into the effects of mistletoe therapy on the emotional, mental, and spiritual level are warranted.

Predictors of sustained use of mobile health applications: Content analysis of user perspectives from a fever management app.

Objectives: Mobile health applications could be means of educating and changing behaviours of their users. Their features and qualities determine the sustainability of use. The FeverApp with two main features of information and documentation is a research-based app. In this observational cohort study, to evaluate the influential predictors of use, users' feedback on the FeverApp, were analyzed. Methods: Feedback is given using a structured questionnaire, four Likert items and two open questions regarding positive and negative impressions, available via app menu. Conventional content analysis (inductive approach) on the two open questions was performed. Comments were grouped into 12 codes. These codes were grouped hierarchically in an iterative process into nine subcategories and lastly into two main categories 'format' and 'content'. Descriptive and quantitative analysis were performed. Results: Out of 8243 users, 1804 of them answered the feedback questionnaire. The features of the app (N = 344), followed by the information aspect (N = 330) were most frequently mentioned. Documentation process (N = 226), request for new features or improvement of the current ones (N = 193), and functioning (N = 132) were also highlighted in users' feedback. App's ease of use, design and being informative were important for the users. The first impression of the app seems important as the majority of feedback were given during the first month of using the app. Conclusion: In-app feedback function could highlight shortcomings and strengths of mobile health apps. Taking users' feedback into consideration could increase the chance of sustained use. Besides ease of use and clear, likeable designs, users want apps that serve their needs while saving time.

High-throughput shoot phenotyping reveals temporal growth responses to nitrogen and inorganic and organic phosphorus sources in tomato.

The application of nitrogen (N) and phosphorus (P) fertilizers to soils is required to maintain crop yields, so the sufficient and timely delivery of nutrients to match crop demand is important in fertilizer management. We quantified temporal growth responses of tomato plants with different rates of N and P application using high-throughput shoot phenotyping. The tomato plants were grown in soil that had organic, inorganic or a combination of sources of P incorporated. Additional N was added to each pot at low and high rates, 13 days after planting. At the same rate of total P application, the inorganic P source resulted in greater shoot growth at the early time points. Later on, the plants supplied with organic or mixed P sources grew faster than those that received the inorganic P source, resulting in comparable shoot biomass in all treatments at the time of destructive harvest. The shoot phenotyping data demonstrated that readily available soil P was important for early tomato growth while available N was more important in later stages of vegetative growth. These results suggest that a fertilizer formulation of combined inorganic and organic P sources may be able to sustain rapid and great shoot growth in tomato plants, while also reducing additional N input.

Combined Heterozygous Genetic Variations in Complement C2 and C8B: An Explanation for Multidimensional Immune Imbalance?

The complement system plays a crucial role in host defense, homeostasis, and tissue regeneration and bridges the innate and the adaptive immune systems. Although the genetic variants in complement C2 (c.839_849+17del; p.(Met280Asnfs*5)) and C8B (c.1625C>T; p.(Thr542Ile)) are known individually, here, we report on a patient carrying their combination in a heterozygous form. The patient presented with a reduced general condition and suffers from a wide variety of autoimmune diseases. While no autoimmune disease-specific autoantibodies could be detected, genetic analysis revealed abnormalities in the two complement genes C2 and C8B. Therefore, we performed a comprehensive investigation of the innate immune system on a cellular and humoral level to define the functional consequences. We found slightly impaired functionality of neutrophils and monocytes regarding phagocytosis and reactive oxygen species generation and a diminished expression of the C5aR1. An extensive complement analysis revealed a declined activation potential for the alternative and classical pathway. Reconstitution with purified C2 and C8 into patient serum failed to normalize the dysfunction, whereas the addition of C3 improved the hemolytic activity. In clinical transfer, in vitro supplementation of the patient's plasma with FFP as a complement source could fully restore full complement functionality. This study describes for the first time a combined heterozygous genetic variation in complement C2 and C8B which, however, cannot fully explain the overall dysfunctions and calls for further complement deficiency research and corresponding therapies.

Improved Salinity Tolerance-Associated Variables Observed in EMS Mutagenized Wheat Lines.

Salinity tolerance-associated phenotypes of 35 EMS mutagenized wheat lines originating from BARI Gom-25 were compared. Vegetative growth was measured using non-destructive image-based phenotyping. Five different NaCl concentrations (0 to 160 mM) were applied to plants 19 days after planting (DAP 19), and plants were imaged daily until DAP 38. Plant growth, water use, leaf Na+, K+ and Cl- content, and thousand kernel weight (TKW) were measured, and six lines were selected for further analysis. In saline conditions, leaf Na+, K+, and Cl- content variation on a dry weight basis within these six lines were ~9.3, 1.4, and 2.4-fold, respectively. Relative to BARI Gom-25, two (OA6, OA62) lines had greater K+ accumulation, three (OA6, OA10, OA62) had 50-75% lower Na+:K+ ratios, and OA62 had ~30% greater water-use index (WUI). OA23 had ~2.2-fold greater leaf Na+ and maintained TKW relative to BARI Gom-25. Two lines (OA25, OA52) had greater TKW than BARI Gom-25 when grown in 120 mM NaCl but similar Na+:K+, WUI, and biomass accumulation. OA6 had relatively high TKW, high leaf K+, and WUI, and low leaf Na+ and Cl-. Phenotypic variation revealed differing associations between the parameters measured in the lines. Future identification of the genetic basis of these differences, and crossing of lines with phenotypes of interest, is expected to enable the assessment of which combinations of parameters deliver the greatest improvement in salinity tolerance.

Corrigendum to: Identification of salt tolerance QTL in a wheat RIL mapping population using destructive and non-destructive phenotyping.

Bread wheat (Triticum aestivum L.) is one of the most important food crops, however it is only moderately tolerant to salinity stress. To improve wheat yield under saline conditions, breeding for improved salinity tolerance of wheat is needed. We have identified nine quantitative trail loci (QTL) for different salt tolerance sub-traits in a recombinant inbred line (RIL) population, derived from the bi-parental cross of Excalibur × Kukri. This population was screened for salinity tolerance subtraits using a combination of both destructive and non-destructive phenotyping. Genotyping by sequencing (GBS) was used to construct a high-density genetic linkage map, consisting of 3236 markers, and utilised for mapping QTL. Of the nine mapped QTL, six were detected under salt stress, including QTL for maintenance of shoot growth under salinity (QG ( 1-5 ) .asl -5A , QG ( 1-5 ) .asl -7B ) sodium accumulation (QNa.asl -2A ), chloride accumulation (QCl.asl -2A , QCl.asl -3A ) and potassium : sodium ratio (QK :Na.asl -2DS2 ). Potential candidate genes within these QTL intervals were shortlisted using bioinformatics tools. These findings are expected to facilitate the breeding of new salt tolerant wheat cultivars. Soil salinity causes major yield losses in bread wheat, which is moderately tolerant to salinity stress. Using high throughput genotyping and phenotyping techniques, we identified quantitative trail loci (QTL) for different salt tolerance sub-traits in bread wheat and shortlisted potential candidate genes. These QTL and candidate genes may prove useful in breeding for salt tolerant wheat cultivars.

Sensor-based phenotyping of above-ground plant-pathogen interactions.

Plant pathogens cause yield losses in crops worldwide. Breeding for improved disease resistance and management by precision agriculture are two approaches to limit such yield losses. Both rely on detecting and quantifying signs and symptoms of plant disease. To achieve this, the field of plant phenotyping makes use of non-invasive sensor technology. Compared to invasive methods, this can offer improved throughput and allow for repeated measurements on living plants. Abiotic stress responses and yield components have been successfully measured with phenotyping technologies, whereas phenotyping methods for biotic stresses are less developed, despite the relevance of plant disease in crop production. The interactions between plants and pathogens can lead to a variety of signs (when the pathogen itself can be detected) and diverse symptoms (detectable responses of the plant). Here, we review the strengths and weaknesses of a broad range of sensor technologies that are being used for sensing of signs and symptoms on plant shoots, including monochrome, RGB, hyperspectral, fluorescence, chlorophyll fluorescence and thermal sensors, as well as Raman spectroscopy, X-ray computed tomography, and optical coherence tomography. We argue that choosing and combining appropriate sensors for each plant-pathosystem and measuring with sufficient spatial resolution can enable specific and accurate measurements of above-ground signs and symptoms of plant disease.

Hypericum perforatum to Improve Postoperative Pain Outcome After Monosegmental Spinal Sequestrectomy (HYPOS): Results of a Randomized, Double-Blind, Placebo-Controlled Trial.

Introduction: Patients undergoing lumbar spine surgery often suffer from severe radicular postoperative pain leading to the prescription of high-dose opioids. In Integrative Medicine, Hypericum perforatum is known as a remedy to relieve pain caused by nerve damage. Objectives: This trial investigated whether homeopathic Hypericum leads to a reduction in postoperative pain and a decrease in pain medication compared with placebo. Design: Randomized double blind, monocentric, placebo controlled clinical trial. Settings/Location: Department of Neurosurgery, Community Hospital Herdecke. Subjects: Inpatients undergoing lumbar sequestrectomy surgery. Interventions: Homeopathic treatment versus placebo in addition to usual pain management. Outcomes Measures: Primary endpoint was pain relief measured with a visual analog scale. Secondary endpoints were the reduction of inpatient postoperative analgesic medication and change in sensory and affective pain perception. Results: Baseline characteristics were comparable between the groups. Pain perception between baseline and day 3 did not significantly differ between the study arms. With respect to pain medication, total morphine equivalent doses did not differ significantly. However, a statistical trend and a moderate effect (d = 0.432) in the decrease of pain medication consumption in favor of the Hypericum group was observed. Conclusion: This is the first trial of homeopathy that evaluated the efficacy of Hypericum C200 after lumbar monosegmental spinal sequestrectomy. Although no significant differences between the groups could be shown, we found that patients who took potentiated Hypericum in addition to usual pain management showed lower consumption of analgesics. Further investigations, especially with regard to pain medication, should follow to better classify the described analgesic reduction.

Identifying the genetic control of salinity tolerance in the bread wheat landrace Mocho de Espiga Branca.

Salinity tolerance in bread wheat is frequently reported to be associated with low leaf sodium (Na+) concentrations. However, the Portuguese landrace, Mocho de Espiga Branca, accumulates significantly higher leaf Na+ but has comparable salinity tolerance to commercial bread wheat cultivars. To determine the genetic loci associated with the salinity tolerance of this landrace, an F2 mapping population was developed by crossing Mocho de Espiga Branca with the Australian cultivar Gladius. The population was phenotyped for 19 salinity tolerance subtraits using both non-destructive and destructive techniques. Genotyping was performed using genotyping-by-sequencing (GBS). Genomic regions associated with salinity tolerance were detected on chromosomes 1A, 1D, 4B and 5A for the subtraits of relative and absolute growth rate (RGR, AGR respectively), and on chromosome 2A, 2B, 4D and 5D for Na+, potassium (K+) and chloride (Cl-) accumulation. Candidate genes that encode proteins associated with salinity tolerance were identified within the loci including Na+/H+ antiporters, K+ channels, H+-ATPase, calcineurin B-like proteins (CBLs), CBL-interacting protein kinases (CIPKs), calcium dependent protein kinases (CDPKs) and calcium-transporting ATPase. This study provides a new insight into the genetic control of salinity tolerance in a Na+ accumulating bread wheat to assist with the future development of salt tolerant cultivars.

Enantioselective Synthesis of Acyclic Orthogonally Functionalized Compounds Bearing a Quaternary Stereocenter Using Chiral Ammonium Salt Catalysis.

We herein report an asymmetric protocol to access a series of orthogonally functionalized acyclic chiral target molecules containing a quaternary stereogenic center by carrying out the enantioselective α-alkylation of novel orthogonally functionalized dioxolane-containing cyanoacetates under chiral ammonium salt catalysis. By using just 1 mol % of Maruoka's spirocyclic ammonium salt catalysts enantioselectivities up to e.r.=97.5 : 2.5 could be achieved and further functional group manipulations of the products were carried out as well.

Yoga, Eurythmy Therapy and Standard Physiotherapy (YES-Trial) for Patients With Chronic Non-specific Low Back Pain: A Three-Armed Randomized Controlled Trial.

We aimed to evaluate the effects of yoga and eurythmy therapy compared to conventional physiotherapy exercises in patients with chronic low back pain. In a three-armed, multicentre, randomized controlled trial, patients with chronic low back pain were treated for 8 weeks in group sessions (75 minutes once per week). Primary outcome was patients' physical disability (measured by RMDQ) from baseline to week 8. Secondary outcome variables were pain intensity and pain-related bothersomeness (VAS), health-related quality of life (SF-12) and life satisfaction (BMLSS). Outcomes were assessed at baseline, after the intervention at 8 weeks and at a 16-week follow up. Data of 274 participants were used for statistical analyses. There were no significant differences between the three groups for the primary and all secondary outcomes. In all groups, RMDQ decreased comparably at 8 weeks, but did not reach clinical meaningfulness. Pain intensity and pain-related bothersomeness decreased, while quality of life increased in all 3 groups. In explorative general linear models for the SF-12's mental health component participants in the eurythmy arm benefitted significantly more compared to physiotherapy and yoga. Furthermore, within-group analyses showed improvements of SF-12 mental score for yoga and eurythmy therapy only. All interventions were safe. Clinical Trials Register: DRKS-ID: DRKS00004651 Perspective: This article presents the results of a multicentre three-armed randomized controlled trial on the clinical effects of three 8-week programs in patients with chronic low back pain. Compared to the 'gold standard' of conventional physiotherapeutic exercises, eurythmy therapy and yoga therapy lead to comparable symptomatic improvements in patients with chronic low back pain. However, the within-group effect sizes were small to moderate and did not reach clinical meaningfulness on patients' physical disability (RMDQ).

Seven-day fasting as a multimodal complex intervention for adults with type 1 diabetes: Feasibility, benefit and safety in a controlled pilot study.

OBJECTIVES: Intermittent as well as prolonged fasting are receiving considerable attention and appear favorable in conditions such as metabolic syndrome, type 2 diabetes, and rheumatic diseases. Fasting for individuals with type 1 diabetes (T1D) is generally considered too risky. However, the ability and possibility to change from carbohydrate- to ketone-based fuel supply might be relevant for individuals with T1D. The aim of this patient-led research was to investigate the feasibility, benefit, and safety of a 7-d multimodal fasting intervention in individuals with T1D. METHODS: This was a non-randomized controlled pilot study, with 20 participants with T1D and 10 without the disease. Data acquisition took place before, after, and 4 mo after the intervention and daily during intervention. RESULTS: Of the individuals with T1D, 19 finished fasting. A mean ß-hydroxybutyrate as representative ketone body increased to 2.8 ± 1.9 mmol/L on day 7; whereas average glucose remained between 4.9 (±1.5) and 7.5 (±2.3) mmol/L (89 ± 27 and 136 ± 40 mg/dL). Mean daily insulin dose was adjusted from 24.4 (3-50) IU on the day before fasting to 7.6 (0-26.7) IU on day 7. Quality of life (WHO-5) normalized from 54 (±4.4) to 68.8 (±15; P = 0.01) after fasting. There was a decrease from before until the follow-up 4 mo later of weight from 77.6 (±20.4) to 76.6 (±20.9) kg (P = 0.023) and for body mass index from 27.68 (±7.04) to 26.74 (±7.15) kg/m2 (P = 0.008). Diastolic blood pressure increased from 69.75 (±11.41) to 75.74 (±8.42) mm Hg (P = 0.028) and stayed in a healthy range on average. Fasting-related side effects were all temporary, and slightly more prevalent in those with type 1 diabetes compared with the reference group. CONCLUSIONS: This study demonstrated the feasibility, benefits, and safety aspects of a 7-d fast in adults with T1D.

Genome-wide association study reveals the genetic complexity of fructan accumulation patterns in barley grain.

We profiled the grain oligosaccharide content of 154 two-row spring barley genotypes and quantified 27 compounds, mainly inulin- and neoseries-type fructans, showing differential abundance. Clustering revealed two profile groups where the 'high' set contained greater amounts of sugar monomers, sucrose, and overall fructans, but lower fructosylraffinose. A genome-wide association study (GWAS) identified a significant association for the variability of two fructan types: neoseries-DP7 and inulin-DP9, which showed increased strength when applying a novel compound ratio-GWAS approach. Gene models within this region included three known fructan biosynthesis genes (fructan:fructan 1-fructosyltransferase, sucrose:sucrose 1-fructosyltransferase, and sucrose:fructan 6-fructosyltransferase). Two other genes in this region, 6(G)-fructosyltransferase and vacuolar invertase1, have not previously been linked to fructan biosynthesis and showed expression patterns distinct from those of the other three genes, including exclusive expression of 6(G)-fructosyltransferase in outer grain tissues at the storage phase. From exome capture data, several single nucleotide polymorphisms related to inulin- and neoseries-type fructan variability were identified in fructan:fructan 1-fructosyltransferase and 6(G)-fructosyltransferase genes. Co-expression analyses uncovered potential regulators of fructan biosynthesis including transcription factors. Our results provide the first scientific evidence for the distinct biosynthesis of neoseries-type fructans during barley grain maturation and reveal novel gene candidates likely to be involved in the differential biosynthesis of various types of fructan in barley.

Identification of salt tolerance QTL in a wheat RIL mapping population using destructive and non-destructive phenotyping.

Bread wheat (Triticum aestivum L.) is one of the most important food crops, however it is only moderately tolerant to salinity stress. To improve wheat yield under saline conditions, breeding for improved salinity tolerance of wheat is needed. We have identified nine quantitative trail loci (QTL) for different salt tolerance sub-traits in a recombinant inbred line (RIL) population, derived from the bi-parental cross of Excalibur × Kukri.

Genotyping by sequencing (GBS) was used to construct a high-density genetic linkage map, consisting of 3236 markers, and utilised for mapping QTL. Of the nine mapped QTL, six were detected under salt stress, including QTL for maintenance of shoot growth under salinity (QG(1-5).asl-5A, QG(1-5).asl-7B) sodium accumulation (QNa.asl-2A), chloride accumulation (QCl.asl-2A, QCl.asl-3A) and potassium:sodium ratio (QK:Na.asl-2DS2). Potential candidate genes within these QTL intervals were shortlisted using bioinformatics tools. These findings are expected to facilitate the breeding of new salt tolerant wheat cultivars.

Effect of Rice GDP-L-Galactose Phosphorylase Constitutive Overexpression on Ascorbate Concentration, Stress Tolerance, and Iron Bioavailability in Rice.

Ascorbate (vitamin C) is an essential multifunctional molecule for both plants and mammals. In plants, ascorbate is the most abundant water-soluble antioxidant that supports stress tolerance. In humans, ascorbate is an essential micronutrient and promotes iron (Fe) absorption in the gut. Engineering crops with increased ascorbate levels have the potential to improve both crop stress tolerance and human health. Here, rice (Oryza sativa L.) plants were engineered to constitutively overexpress the rice GDP-L-galactose phosphorylase coding sequence (35S-OsGGP), which encodes the rate-limiting enzymatic step of the L-galactose pathway. Ascorbate concentrations were negligible in both null segregant (NS) and 35S-OsGGP brown rice (BR, unpolished grain), but significantly increased in 35S-OsGGP germinated brown rice (GBR) relative to NS. Foliar ascorbate concentrations were significantly increased in 35S-OsGGP plants in the vegetative growth phase relative to NS, but significantly reduced at the reproductive growth phase and were associated with reduced OsGGP transcript levels. The 35S-OsGGP plants did not display altered salt tolerance at the vegetative growth phase despite having elevated ascorbate concentrations. Ascorbate concentrations were positively correlated with ferritin concentrations in Caco-2 cells - an accurate predictor of Fe bioavailability in human digestion - exposed to in vitro digests of NS and 35S-OsGGP BR and GBR samples.

Greenhouse Spatial Effects Detected in the Barley (Hordeum vulgare L.) Epigenome Underlie Stochasticity of DNA Methylation.

Environmental cues are known to alter the methylation profile of genomic DNA, and thereby change the expression of some genes. A proportion of such modifications may become adaptive by adjusting expression of stress response genes but others have been shown to be highly stochastic, even under controlled conditions. The influence of environmental flux on plants adds an additional layer of complexity that has potential to confound attempts to interpret interactions between environment, methylome, and plant form. We therefore adopt a positional and longitudinal approach to study progressive changes to barley DNA methylation patterns in response to salt exposure during development under greenhouse conditions. Methylation-sensitive amplified polymorphism (MSAP) and phenotypic analyses of nine diverse barley varieties were grown in a randomized plot design, under two salt treatments (0 and 75 mM NaCl). Combining environmental, phenotypic and epigenetic data analyses, we show that at least part of the epigenetic variability, previously described as stochastic, is linked to environmental micro-variations during plant growth. Additionally, we show that differences in methylation increase with time of exposure to micro-variations in environment. We propose that subsequent epigenetic studies take into account microclimate-induced epigenetic variability.

High-throughput, image-based phenotyping reveals nutrient-dependent growth facilitation in a grass-legume mixture.

This study used high throughput, image-based phenotyping (HTP) to distinguish growth patterns, detect facilitation and interpret variations to nutrient uptake in a model mixed-pasture system in response to factorial low and high nitrogen (N) and phosphorus (P) application. HTP has not previously been used to examine pasture species in mixture. We used red-green-blue (RGB) imaging to obtain smoothed projected shoot area (sPSA) to predict absolute growth (AG) up to 70 days after planting (sPSA, DAP 70), to identify variation in relative growth rates (RGR, DAP 35-70) and detect overyielding (an increase in yield in mixture compared with monoculture, indicating facilitation) in a grass-legume model pasture. Finally, using principal components analysis we interpreted between species changes to HTP-derived temporal growth dynamics and nutrient uptake in mixtures and monocultures. Overyielding was detected in all treatments and was driven by both grass and legume. Our data supported expectations of more rapid grass growth and augmented nutrient uptake in the presence of a legume. Legumes grew more slowly in mixture and where growth became more reliant on soil P. Relative growth rate in grass was strongly associated with shoot N concentration, whereas legume RGR was not strongly associated with shoot nutrients. High throughput, image-based phenotyping was a useful tool to quantify growth trait variation between contrasting species and to this end is highly useful in understanding nutrient-yield relationships in mixed pasture cultivations.

The Performances of Hyperspectral Sensors for Proximal Sensing of Nitrogen Levels in Wheat.

The accurate and high throughput quantification of nitrogen (N) content in wheat using non-destructive methods is an important step towards identifying wheat lines with high nitrogen use efficiency and informing agronomic management practices. Among various plant phenotyping methods, hyperspectral sensing has shown promise in providing accurate measurements in a fast and non-destructive manner. Past applications have utilised non-imaging instruments, such as spectrometers, while more recent approaches have expanded to hyperspectral cameras operating in different wavelength ranges and at various spectral resolutions. However, despite the success of previous hyperspectral applications, some important research questions regarding hyperspectral sensors with different wavelength centres and bandwidths remain unanswered, limiting wide application of this technology. This study evaluated the capability of hyperspectral imaging and non-imaging sensors to estimate N content in wheat leaves by comparing three hyperspectral cameras and a non-imaging spectrometer. This study answered the following questions: (1) How do hyperspectral sensors with different system setups perform when conducting proximal sensing of N in wheat leaves and what aspects have to be considered for optimal results? (2) What types of photonic detectors are most sensitive to N in wheat leaves? (3) How do the spectral resolutions of different instruments affect N measurement in wheat leaves? (4) What are the key-wavelengths with the highest correlation to N in wheat? Our study demonstrated that hyperspectral imaging systems with satisfactory system setups can be used to conduct proximal sensing of N content in wheat with sufficient accuracy. The proposed approach could reduce the need for chemical analysis of leaf tissue and lead to high-throughput estimation of N in wheat. The methodologies here could also be validated on other plants with different characteristics. The results can provide a reference for users wishing to measure N content at either plant- or leaf-scales using hyperspectral sensors.
