Abstract

Cowpea [Vigna unguiculata (L.) Walp.] is an important legume crop, widely grown in Africa, South America, South Asia, Southeast Asia, and the southern United States. Cowpea is consumed as both fresh vegetable and dry grain, and as an animal feed and fodder, and it is a major dietary protein source that complements cereal-based diet. Cowpea mosaic virus (CPMV) causes a severe yield loss of cowpea in many areas worldwide notably in the Africa. Utilization of host genetic resistance is the most effective control method for the viral disease. The objective of this research is to conduct genome-wide association analysis and identify single nucleotide polymorphism (SNP) markers associated with CPMV resistance in cowpea. Three hundred and thirty-three cowpea germplasm accessions, originally collected from 39 different countries and 1033 SNPs identified from genotyping by sequencing approach were used in this study. Single marker regression, general linear model, and mixed linear model in Tassel 5 were used for association analysis of CPMV resistance. Six SNP markers (C35069548_1883, scaffold65342_6794, scaffold66293_6549, scaffold95805_2175, C35081948_540, and scaffold17319_4417) were strongly associated with the CPMV resistance, of which the first three were associated for immune and the remaining three were associated with hypersensitive response. SNP markers identified in this research will be a potential tool to use in cowpea molecular breeding to develop CPMV resistant cultivars through marker-assisted selection.

Table S1 Cowpea accession, plant name, CPMV rating, origin region (country) and the accessions assigned to clusters based on STRUCTURE 2.3.4 analysis, and a ID composed of accession name, country of origin and STRUCTURE generated cluster group merged into a single taxon name for MEGA analysis in this study. Table S2 SNP marker associated with the cowpea mosaic virus (CPMV) resistance response in cowpea. A panel of 333 accessions were used for the association analysis using two and three population structure components. Association analysis was further conducted on a subset of accessions that were scored as immune and hypersensitive to uncover genetic loci associated with each phenotypic class. Table S3 Selection accuracy calculated for a panel of 333 cowpea accessions. Number of accessions on each genotypic class were counted for all 333 accessions, 231 susceptible accessions and 102 resistant accessions. The 102 resistant accessions consist 47, 48, and 7 genotypes scored as immune, hypersensitive and resistant respectively. Table S4 Selection accuracy calculated for a panel of 278 cowpea accessions scored as immune and susceptible. Number of accessions on each genotypic class were counted for all 278 accessions, 231 susceptible accessions and 47 resistant accessions that were scored as 'immune'. Table S5 Selection accuracy calculated for a panel of 279 cowpea accessions scored as hypersensitive and susceptible. Number of accessions on each genotypic class were counted for all 279 accessions, 231 susceptible accessions and 48 resistant accessions that were scored as 'hypersensitive'.
