The coordinated expression of highly related homoeologous genes in polyploid species underlies the phenotypes many world's major crops. Here we combine extensive gene datasets to produce a comprehensive, genome-wide analysis homoeolog patterns hexaploid bread wheat. Bias varies between tissues, with ~30% wheat homoeologs showing nonbalanced expression. We found asymmetries along chromosomes, largest inter-tissue, inter-cultivar, and coding sequence variation, most often located...
The Brassica napus Illumina array provides genome-wide markers linked to the available genome sequence, a significant tool for genetic analyses of allotetraploid B. and its progenitor diploid genomes. A high-density single nucleotide polymorphism (SNP) Infinium array, containing 52,157 markers, was developed napus. stringent selection process employing short probe sequence each SNP assay used limit majority selected those represented minimum number times across highly replicated genome. As...
Late leaf spot (LLS) and rust are two major foliar diseases of groundnut (Arachis hypogaea L.) that often occur together leading to 50-70% yield loss in the crop. A total 268 recombinant inbred lines a mapping population TAG 24 x GPBD 4 segregating for LLS were used undertake quantitative trait locus (QTL) analysis. Phenotyping was carried out under artificial disease epiphytotics. Positive correlations between different stages, high very heritability independent nature inheritance both...
Late leaf spot (LLS) and rust have the greatest impact on yield losses worldwide in groundnut (Arachis hypogaea L.). With objective of identifying tightly linked markers to these diseases, a total 3,097 simple sequence repeats (SSRs) were screened parents two recombinant inbred line (RIL) populations, namely TAG 24 × GPBD 4 (RIL-4) TG 26 (RIL-5), segregation data obtained for 209 marker loci each mapping populations. Linkage map analysis resulted 188 181 RIL-4 RIL-5 respectively. Using 143...
Camelina sativa is currently being embraced as a viable industrial bio-platform crop due to number of desirable agronomic attributes and the unique fatty acid profile seed oil that has applications for food, feed biofuel. The recent completion reference genome sequence C. identified young hexaploid genome. To complement this work, we have generated genome-wide developmental transcriptome map by RNA sequencing 12 different tissues covering major stages during life cycle sativa. We digital...
The aim of this study was to identify candidate resistance genes for late leaf spot (LLS) and rust diseases in peanut (Arachis hypogaea L.). We used a double-digest restriction-site associated DNA sequencing (ddRAD-Seq) technique based on next-generation (NGS) genotyping analysis across the recombinant inbred lines (RILs) derived from cross between susceptible line, TAG 24, resistant GPBD 4. A total 171 SNPs ddRAD-Seq together with 282 markers published previous studies were mapped genetic...
To develop genetic improvement strategies to modulate raffinose family oligosaccharides (RFO) concentration in chickpea (Cicer arietinum L.) seeds, RFO and their precursor concentrations were analyzed 171 genotypes from diverse geographical origins. The grown replicated trials over two years the field (Patancheru, India) greenhouse (Saskatoon, Canada). Analysis of variance revealed a significant impact genotype, environment, interaction on seeds. Total ranged 1.58 5.31 mmol/100 g 2.11 5.83...
Ethiopian mustard (Brassica carinata A. Braun) is an emerging sustainable source of vegetable oil, in particular for the biofuel industry. The present study exploited genome assemblies Brassica diploids, nigra and oleracea, to discover over 10,000 genome-wide SNPs using genotype by sequencing 620 B. lines. analyses revealed a SNP frequency one every 91.7 kb, heterozygosity level 0.30, nucleotide diversity levels 1.31 × 10
Horsegram is a grain legume with excellent nutritional and remedial properties good climate resilience, able to adapt harsh environmental conditions. Here, we used combination of short- long-read sequencing technologies generate genome sequence 279.12Mb, covering 83.53% the estimated total size horsegram genome, annotated 24,521 genes. De novo prediction DNA repeats showed that approximately 25.04% was made up repetitive sequences, lowest among genomes sequenced so far. The major...
Chickpea (Cicer arietinum L.) is the third most important pulse crop and an excellent source of protein in human diet (Garg et al., 2011). However, presence anti-nutritional factors like raffinose family oligosaccharides (RFO) restrains its acceptability as food feed (Olmedilla Alonso 2010). Higher concentration RFO chickpea seeds affects health negatively plays physiological role plants (Martinez-Villaluenga 2008). Hence, there a need to reduce without affecting plant growth. To achieve...
ABSTRACT Genome prediction (GP) significantly enhances genetic gain by improving selection efficiency and shortening crop breeding cycles. Using a nested association mapping (NAM) population set of diverse scenarios were assessed to evaluate GP for vital agronomic traits in B. napus . accuracy was examined employing different models, marker sets, sizes, densities, incorporating genome-wide (GWAS) markers. Eight including linear semi-parametric approaches, tested. The choice model minimally...
