Like many other crops, the cultivated peanut (Arachis hypogaea L.) is of hybrid origin and has a polyploid genome that contains essentially complete sets chromosomes from two ancestral species. Here we report sequence show after its origin, evolved through mobile-element activity, deletions by flow genetic information between corresponding (that is, homeologous recombination). Uniformity patterns recombination at ends favors single for wild counterpart A. monticola. However, much genome,...
High oil and protein content make tetraploid peanut a leading food legume. Here we report high-quality genome sequence, comprising 2.54 Gb with 20 pseudomolecules 83,709 protein-coding gene models. We characterize functional groups implicated in seed size evolution, content, disease resistance symbiotic nitrogen fixation. The B subgenome has more genes general expression dominance, temporally associated long-terminal-repeat expansion the A that also raises questions about A-genome...
Pearl millet [Cenchrus americanus (L.) Morrone] is a staple food for more than 90 million farmers in arid and semi-arid regions of sub-Saharan Africa, India South Asia. We report the ∼1.79 Gb draft whole genome sequence reference genotype Tift 23D2B1-P1-P5, which contains an estimated 38,579 genes. highlight substantial enrichment wax biosynthesis genes, may contribute to heat drought tolerance this crop. resequenced analyzed 994 pearl lines, enabling insights into population structure,...
Significance We present a draft genome of the peanut A-genome progenitor, Arachis duranensis , providing details on total genes in genome. Genome analysis suggests that lineage was affected by at least three polyploidizations since origin eudicots. Resequencing synthetic tetraploids reveals extensive gene conversion their formation human hands. The A. provides major source candidate for fructification, oil biosynthesis, and allergens, expanding knowledge understudied areas plant biology...
Rust and late leaf spot (LLS) are the two major foliar fungal diseases in groundnut, their co-occurrence leads to significant yield loss addition deterioration of fodder quality. To identify candidate genomic regions controlling resistance rust LLS, whole-genome resequencing (WGRS)-based approach referred as 'QTL-seq' was deployed. A total 231.67 Gb raw 192.10 clean sequence data were generated through WGRS resistant parent susceptible bulks for LLS. Sequence analysis LLS with...
Terminal drought is a major constraint to chickpea productivity. Two component traits responsible for reduction in yield under stress include seeds size and root length/root density. QTL-seq approach, therefore, was used identify candidate genomic regions 100-seed weight (100SDW) total dry plant ratio (RTR) rainfed conditions. Genomewide SNP profiling of extreme phenotypic bulks from the ICC 4958 × 1882 population identified two significant regions, one on CaLG01 (1.08 Mb) another CaLG04...
Abstract Zero hunger and good health could be realized by 2030 through effective conservation, characterization utilization of germplasm resources 1 . So far, few chickpea ( Cicer arietinum ) accessions have been characterized at the genome sequence level 2 Here we present a detailed map variation in 3,171 cultivated 195 wild to provide publicly available for genomics research breeding. We constructed pan-genome describe genomic diversity across its progenitor accessions. A divergence tree...
Abstract Adzuki bean ( Vigna angularis var. ) is a dietary legume crop in East Asia. The presumed progenitor nipponensis widely found Asia, suggesting speciation and domestication these temperate climate regions. Here, we report draft genome sequence of adzuki bean. assembly covers 75% the estimated was mapped to 11 pseudo-chromosomes. Gene prediction revealed 26,857 high confidence protein-coding genes evidenced by RNAseq different tissues. Comparative gene expression analysis with V....
Abstract Single nucleotide polymorphisms (SNPs) are the most abundant DNA sequence variation in genomes which can be used to associate genotypic phenotype. Therefore, availability of a high-density SNP array with uniform genome coverage advance genetic studies and breeding applications. Here we report development ‘Axiom _Arachis ’ 58 K SNPs its utility groundnut diversity study. In this context, from total 163,782 derived resequencing RNA-sequencing 41 accessions wild diploid ancestors,...
Peanut (Arachis hypogaea; 2n = 4x 40) is a nutritious food and good source of vitamins, minerals, healthy fats. Expansion genetic genomic resources for enhancement cultivated peanut has gained momentum from the sequenced genomes diploid ancestors peanut. To facilitate high-throughput genotyping Arachis species, 20 genotypes were re-sequenced genome-wide single nucleotide polymorphisms (SNPs) selected to develop large-scale SNP array. For flexibility in applications, SNPs polymorphic between...
Summary To map resistance genes for Fusarium wilt ( FW ) and sterility mosaic disease SMD in pigeonpea, sequencing‐based bulked segregant analysis (Seq‐ BSA was used. Resistant (R) susceptible (S) bulks from the extreme recombinant inbred lines of ICPL 20096 × 332 were sequenced. Subsequently, SNP index calculated between R‐ S‐bulks with help draft genome sequence reference‐guided assembly (resistant parent). Seq‐ has provided seven candidate s pigeonpea. In parallel, four additional...
Haplotype-based breeding, a recent promising breeding approach to develop tailor-made crop varieties, deals with identification of superior haplotypes and their deployment in programmes. In this context, whole genome re-sequencing data 292 genotypes from pigeonpea reference set were mined identify the for 10 drought-responsive candidate genes. A total 83, 132 60 identified lines, landraces wild species, respectively. Candidate gene-based association analysis these genes on subset 137...
Abstract With an aim of enhancing drought tolerance using a marker‐assisted backcrossing (MABC) approach, we introgressed the “ QTL‐hotspot ” region from ICC 4958 accession that harbors quantitative trait loci (QTLs) for several drought‐tolerance related traits into three elite Indian chickpea ( Cicer arietinum L.) cultivars: Pusa 372, 362, and DCP 92‐3. Of eight simple sequence repeat (SSR) markers in region, two to polymorphic were used foreground selection with respective...
In order to understand the impact of breeding on genetic diversity and gain insights into temporal trends in chickpea, a set 100 chickpea varieties released 14 countries between 1948 2012 were re-sequenced.
