This study focuses on the genetic regulation mechanism of flower pigments in Brassica napus, with a particular emphasis on analyzing the roles of anthocyanins and carotenoids in flower color formation. Through metabolomics and RNA sequencing techniques, key genes and metabolites involved in flower color formation were identified, such as BnaA07.PAP2 and BnaA03.ANS genes that regulate red petal coloring, as well as BnaA09.ZEP and BnaC09.ZEP genes that affect orange petals. The regulatory role of these genes in metabolic pathways through transcription factors was revealed, and the effects of epigenetic and environmental factors on pigment formation were explored. The functions of key genes were validated through CRISPR/Cas9 and other techniques. The research results provide a genetic basis for improving the ornamental value of rapeseed, optimizing pollination efficiency, and enhancing stress resistance. At the same time, it also points out the need for further research on complex genetic networks and environmental gene interaction mechanisms in the future.
