BSR-seq for mapping the causal gene responsible for peel color variation in eggplant
Eggplant (Solanum melongena) is a globally important vegetable crop. The color of its fruit peel, ranging from anthocyanin-rich purple to green or white, is a key quality trait that influences consumer preference and market value. To identify the causal genes regulating anthocyanin accumulation in eggplant peels, we developed an F2 segregating population by crossing the purple-peel variety PI249568 with the green-peel variety Zao Qing. Using bulk segregant RNA sequencing (BSR-seq), we mapped the candidate gene by analyzing RNA from two extreme pools (purple-peel and green-peel pools) derived from the population.
