Map-based cloning and characterization of BoCCD4, a gene responsible for white/ yellow petal color in B. oleracea

Brassica oleracea exhibits extensive phenotypic diversity. As an important trait, petal color varies among different B. oleracea cultivars, enabling the study of the genetic basis of this trait. In a previous study, the gene responsible for petal color in B. oleracea was mapped to a 503-kb region on chromosome 3, but the candidate gene has not yet been identified.
