| description | Seed coat color is an important consumer-related trait of the cowpea (<i>Vigna unguiculata</i> [L.] Walp.) and has been a subject of study for over a century. Utilizing newly available resources, including mapping populations, a high-density genotyping platform, and several genome assemblies, the red seed coat color has been mapped to two loci, <i>Red-1</i> (<i>R-1</i>) and <i>Red-2</i> (<i>R-2</i>), on Vu03 and Vu07, respectively. A gene model (<i>Vigun03g118700</i>) encoding a dihydroflavonol 4-reductase, a homolog of anthocyanidin reductase 1, which catalyzes the biosynthesis of epicatechin from cyanidin, has been identified as a candidate gene for <i>R-1.</i> Possible causative variants have also been identified for <i>Vigun03g118700</i>. A gene model on Vu07 (<i>Vigun07g118500</i>), with predicted nucleolar function and high relative expression in the developing seed, has been identified as a candidate for <i>R-2</i>. The observed red color is believed to be the result of a buildup of cyanidins in the seed coat. |
