This study compared the main characteristics of different purple intensity cabbage lines, summarized the expression differences of multiple key structural genes and regulatory genes in the anthocyanin synthesis pathway among different strains, and pointed out that the MBW complex plays a core role in regulating the entire pathway. It also sorted out the interaction mode between environmental signals and molecular regulatory networks It explains how external factors such as light and low temperature affect the expression of related genes. Through the joint analysis of metabolomics and transcriptomics, the key links influencing the anthocyanin pathway flux were identified, and the main molecular reasons for the differences in purple intensity were explained. The possible applications of technologies such as molecular marker-assisted selection, CRISPR/Cas gene editing and nutritional fortification in the breeding of high-anthocyanin cabbage were also discussed. This study aims to provide reference and theoretical support for the color improvement and nutritional enhancement of cruciferous vegetables.
