Fine-Mapping of a Red-Skinned Taproot Gene in Radish (<i>Raphanus sativus</i> L.).

ABSTRACT: The skin color of radish taproots is an important commodity character that directly affects the choice behavior of consumers. Here, we identified a skin color gene carried by a red-skinned inbred line, SXAU-R2. Genetic population was constructed by the crossing of SXAU-R2 and a white-skinned inbred line, SXAU-W2, and the taproots of F₁ plants exhibited intermediate color. In the F₂ population, the separation ratio of taproot skin color indicated that the phenotype was controlled by one major locus, named RST1 (Red-Skinned Taproot 1). Combined with bulked segregant analysis and RNA sequencing (BSA-seq), 2640 single nucleotide polymorphisms (SNPs) were detected between the annotated genes of the red skin bulk and white skin bulk. Molecular markers were dev
