Summary Cowpea ( Vigna unguiculata [L.] Walp.) is a major crop for worldwide food and nutritional security, especially in sub‐Saharan Africa, that resilient to hot drought‐prone environments. An assembly of the single‐haplotype inbred genome cowpea IT97K‐499‐35 was developed by exploiting synergies between single‐molecule real‐time sequencing, optical genetic mapping, an reconciliation algorithm. A total 519 Mb included assembled sequences. Nearly half sequence composed repetitive elements,...
Summary Multi‐parent advanced generation inter‐cross ( MAGIC ) populations are an emerging type of resource for dissecting the genetic structure traits and improving breeding populations. We developed a population cowpea Vigna unguiculata L. Walp.) from eight founder parents. These founders were genetically diverse carried many abiotic biotic stress resistance, seed quality agronomic relevant to improvement in United States sub‐Saharan Africa, where is vitally important human diet local...
Herbivory is fundamental to the regulation of both global food webs and extent agricultural crop losses. Induced plant responses herbivores promote resistance often involve perception specific herbivore-associated molecular patterns (HAMPs); however, precisely defined receptors elicitors associated with herbivore recognition remain elusive. Here, we show that a receptor confers signaling defense outputs in response HAMP common caterpillar oral secretions (OS). Staple crops, including cowpea...
Cowpea (Vigna unguiculata L. Walp) is a warm-season legume with genetically diverse gene-pool composed of wild and cultivated forms. domestication involved considerable phenotypic changes from the progenitor, including reduction pod shattering, increased organ size, in flowering time. Little known about genetic basis underlying these changes. In this study, 215 recombinant inbred lines derived cross between cowpea accession were used to evaluate nine domestication-related traits (pod...
Abstract Cowpea, Vigna unguiculata L . Walp., is a diploid warm‐season legume of critical importance as both food and fodder in sub‐Saharan Africa. This species also grown Northern Africa, Europe, Latin America, North East to Southeast Asia. To capture the genomic diversity domesticates this important legume, de novo genome assemblies were produced for representatives six subpopulations cultivated cowpea identified previously from genotyping several hundred diverse accessions. In most...
Abstract Seed coat color is an important part of consumer preferences for cowpea (Vigna unguiculata [L.] Walp). Color has been studied in numerous crop species and often linked to loci controlling the anthocyanin biosynthesis pathway. This study makes use available resources, including mapping populations, a reference genome, high-density single nucleotide polymorphism genotyping platform, map black seed purple pod tip traits, with gene symbol Bl, cowpea. Several models encoding MYB domain...
The appearance of the seed is an important aspect consumer preference for cowpea (Vigna unguiculata [L.] Walp.). Seed coat pattern in has been a subject study over century. This makes use newly available resources, including mapping populations, reference genome and additional assemblies, high-density single nucleotide polymorphism genotyping platform, to map various traits three loci, concurrent with Color Factor (C), Watson (W), Holstein (H) factors identified previously. Several gene...
Abstract Incorporation of new sources genetic diversity into plant breeding programs is crucial for continuing to improve yield and quality, as well tolerance abiotic biotic stresses. A minicore (the “University California, Riverside (UCR) Minicore”) composed 368 worldwide accessions cultivated cowpea has been assembled, having derived from the UCR collection. High‐density genotyping with 51,128 SNPs followed by principal component assignment analyses identified six subpopulations in...
Cowpea (Vigna unguiculata (L.) Walp.) is an important legume crop with enormous nutritional, agronomic and economic value. constitutes a large portion of the daily diet among many people in Africa, Asia, Central America, Southern America. The United States was top 10 global producers cowpea until 1967, when grown primarily for soil management livestock feed. With projected increase minority population States, from 25% 1992 to 47% 2050, it expected that consumption nation will substantially....
Seed coat color is an important consumer-related trait of the cowpea (Vigna unguiculata [L.] Walp.) and has been a subject study for over century. Utilizing newly available resources, including mapping populations, high-density genotyping platform, several genome assemblies, red seed mapped to two loci, Red-1 (R-1) Red-2 (R-2), on Vu03 Vu07, respectively. A gene model (Vigun03g118700) encoding dihydroflavonol 4-reductase, homolog anthocyanidin reductase 1, which catalyzes biosynthesis...
SUMMARY Seed colors and color patterns are critical for the survival of wild plants consumer appeal crops. In common bean, a major global staple, these also essential in determining market classes, yet genetic environmental control many pigmentation remains unresolved. this study, we genetically mapped variation several important seed pattern loci, including T , Bip p hbw Z, which co‐segregated with candidate genes PvTTG1 PvMYC1 PvTT8 PvTT2 respectively. Proteins encoded by predicted to work...
Abstract Pod shattering, which causes the explosive release of seeds from pod, is one main sources yield losses in cowpea arid and semi-arid areas. Reduction shattering has therefore been a primary target for selection during domestication improvement cowpea, among other species. Using mini-core diversity panel 368 accessions, four regions with statistically significant association pod were identified. Two genes (Vigun03g321100 Vigun11g100600), involved cell wall biosynthesis, identified as...

Utilizing newly available resources, including mapping populations, high-density genotyping platform, several genome assemblies, red seed mapped to two loci, Red-1 R-1 ) Red-2 R-2 ), on Vu03 Vu07, respectively. A gene model Vigun03g118700 encoding dihydroflavonol 4-reductase, homolog anthocyanidin reductase 1, which catalyzes the...
Fruit development has been central in the evolution and domestication of flowering plants. In common bean (Phaseolus vulgaris), principal global grain legume staple, two main production categories are distinguished by fibre deposition pods: dry beans, with fibrous, stringy pods; stringless snap/green reduced deposition, which frequently revert to ancestral state. Here, we identify genetic developmental patterns associated pod deposition. Transcriptional, anatomical, epigenetic regulation...
The root-knot nematode (RKN) species Meloidogyne incognita and M. javanica cause substantial root system damage suppress yield of susceptible cowpea cultivars. narrow-based genetic resistance conferred by the Rk gene, present in some commercial cultivars, is not effective against Rk-virulent populations found several production areas. dynamics virulence within RKN require a broadening base elite As part this goal, F1 F2 from cross CB46-Null (susceptible) x FN-2-9-04 (resistant) were...
Perennial habit and floral scent are major traits that distinguish domesticated cowpeas from their wild relatives. However, the genetic basis of these two important remains largely unknown in cowpea. Plant longevity, a perenniality-related trait, scent, an outcrossing were investigated using RIL population derived cross between QTL analysis revealed three significant loci, one on chromosome 8 associated with plant longevity two, chromosomes 1 11, for scent. Genes within regions identified....
