Abstract excerpt
KEY MESSAGE: Anthocyanin deficiency in eggplant peel results from natural variation at the SmFAP1 locus, involving a 6-bp deletion that disrupts DNA binding and a second loss-of-function allele, which enables marker-assisted selection. Anthocyanins, the pigments responsible for purple coloration in eggplant peels, significantly influence consumer preference and market value. However, the genetic basis of natural...
