Promoter variation in BraHDAC1 modulates stomatal regulation and thermotolerance in Brassica rapa
Abstract Heat stress severely limits the productivity of Brassica rapa, a key vegetable crop worldwide. Deciphering the genetic basis of thermotolerance is essential for developing climate-resilient cultivars. By integrating genome-wide association studies (GWAS) with bulked segregant analysis (BSA), we identified two single nucleotide polymorphism (SNP1 and SNP2) in the promoter of the histone…
