This study introduces the genetic mechanism and regulatory mode of flower color formation in rape (Brassica napus), and explains several key genes involved in the synthesis of anthocyanins, flavonoids and carotenoids, such as BnaPAP1, BnaTTG1 and BnaCRTISO, which are the core basis for the diversification of petal colors. This study, through comparative analysis with other closely related species, revealed the significant role of polyploidization and changes in regulatory patterns in the evolution of flower color, emphasizing the practical value of flower color in breseding. In the future, as long as we continue to combine these genomic tools and conduct in-depth research on the interaction between genes and the environment, there is hope to precisely control flower color traits and meet the demands of rapeseed in both practical and ornamental aspects.
