Cereal grains are the dominant source of cadmium in human diet, with rice being to fore. Here we explore effect geographic, genetic, and processing (milling) factors on grain consumption rates that lead dietary variance intake. From a survey 12 countries four continents, levels were highest Bangladesh Sri Lanka, both these also having high per capita intakes. For there was weekly intake from rice, leading intakes deemed unsafe by international national regulators. While genetic variance,...
The concentration of arsenic (As) in rice grains has been identified as a risk to human health. high proportion inorganic species As (Asi) is particular concern it nonthreshold, class 1 carcinogen. To be able breed with low grain As, an understanding genetic variation and the effect different environments on needed. In this study, 13 cultivars grown at two field sites each Bangladesh, India, China are evaluated for As. There was significant site, genotype, site by genotype interaction total...
Abstract The crop management practice of alternate wetting and drying ( AWD ) is being promoted by IRRI the national research extension program in Bangladesh other parts world as a water‐saving irrigation that reduces environmental impact dry season rice production through decreased water usage, potentially increases yield. Evidence growing will dramatically reduce concentration arsenic harvested grains conferring third major advantage over permanently flooded production. may also increase...
• The genetics of arsenic tolerance in plants has not been extensively studied and no gene genetically mapped. Screening 20 diverse genotypes rice for reduced root growth 13.3 m arsenate identified marked differences tolerance. most sensitive variety, Dawn, is known to be highly susceptible straighthead, a condition linked contamination soil. 108 recombinant inbred lines the Bala × Azucena mapping population revealed presence major gene, AsTol, which mapped between markers RZ516 RG213 on...
Arsenic (As) contamination of paddy soils threatens rice cultivation and the health populations relying on as a staple crop. In present study, isotopic dilution techniques were used to determine chemically labile (E value) phytoavailable (L pools As in range from Bangladesh, India, China two arable UK varying degree sources contamination. The E value accounted for 6.2–21.4% total As, suggesting that large proportion soil is nonlabile. L values measured with grown under anaerobic conditions...
Genetic diversity among rice cultivars from Bangladesh and North East India was assessed using a custom 384-SNP microarray assay. A total of 511 were obtained several sources, choosing landraces likely to be the aus subpopulation modern improved Bangladesh. Cultivars OryzaSNP set Rice Diversity Panel 1 (RDP1) also included for reference.The population analysis program STRUCTURE used infer putative groups in panel, revealing four groups: indica (76 cultivars), japonica (55) two distinct...
Flax (Linum usitatissimum) is a cool season crop commercially cultivated for seed oil and stem fibre production. A comprehensive characterization of the heat shock factor (HSF) candidate genes in flax can accelerate genetic improvement adaptive breeding high temperature stress tolerance. We report genome-wide identification 34 putative HSF from genome, which we mapped on 14 15 chromosomes. Through comparative homology analysis, classified these into three broad groups, sub-groups. The...
It has previously been shown that across different arsenic (As) soil environments, a decrease in grain selenium (Se), zinc (Zn), and nickel (Ni) concentrations is associated with an increase As. In this study we aim to determine if there genetic element for observation or it driven by the As environment. To environmental effect on composition, multielement analysis using ICP-MS was performed rice from range of cultivars grown 4 field sites (2 Bangladesh 2 West Bengal). At all four negative...
In this study, the genetic mapping of tolerance root growth to 13.3 μM arsenate [As(V)] using Bala×Azucena population is improved, and candidate genes for further study are identified. A remarkable three-gene model advanced, which appears involve epistatic interaction between three major genes, two on chromosome 6 one 10. Any combination these inherited from tolerant parent leads plant having tolerance. Lists potential positional presented. These then refined whole genome transcriptomics...
Three sesame genotypes (Rama, SI 1666 and IC 21706) were treated with physical (γ-rays: 200 Gy, 400 Gy or 600 Gy) chemical (ethyl methane sulphonate, EMS: 0.5%, 1.0%, 1.5% 2.0%) mutagens their mutagenic effectiveness efficiency estimated in the M (2) generation. The (3) generation was used to identify most effective mutagen dose for induction of mutations. average EMS much higher than γ-rays. lowest γ-rays (200 concentration (0.5%) showed highest all genotypes. Analysis data based on...
Seed coat colour of sesame is commercially an important trait. Developing white seeded varieties with long lasting luster has received momentous attention in most the major producing countries including India. The present investigation centered on genetic control seed sesame. No nomenclature available to describe colour. This first attempt designate genes engendering specific findings are based five different crosses belonging white, beige and various shades brown In general, tetragenic...
Thirty mutant lines selected from 3 widely adapted genotypes of sesame viz. Rama, SI 1666 and IC 21706 (ten each the three genotypes), developed by induced physical (?-rays) chemical (EMS) mutagens, were evaluated against their respective control genotype for yield its important attributes in M4 generation to reveal ramification mutagens disclosing magnitude variation among mutants advance also identify promising positive refurbish new improved varieties sesame. Mutants professing higher...
Abstract Swertia chirayita (Roxb. ex. Fleming) is a high value medicinal plant due the presence of various alkaloids used in different purposes. It already declared as one critically endangered plants whole world. Its slow rate seed germination also triggers problem danger its near extinction. In view that, cytological study and bagging experiment field were done order to find nature pollination. Whole set experiments carried out year 2007 understand reproductive biology, floral biology...
