摘要: Yellow seed is one favorite trait for the breeding of Brassica oilseed crops, but the performance of seed coat color is very complicated due to the involvement of various pigments. The change of seed coat color of Brassica crops is related to the specific synthesis and accumulation of anthocyanin, and the expression level of structural genes in anthocyanin synthesis pathway is specifically regulated by transcription factors. Despite some previous reports on the regulations of seed coat color from linkage marker development, gene fine-mapping and multi-omics association analysis, the trait of Brassica crops is affected by the evolutionary events such as genome triploidization, the regulatory mechanism is still largely unknown. In this study, we identified genes related to anthocyanin synthesis in six Brassica crops in U-triangle at the genome-wide level and performed collinearity analysis. A total of 1119 anthocyanin-related genes were identified, the collinear relationship of anthocyanin-related genes on subgenomic chromosomes was the best in B. napus (AACC) and the worst in B. carinata (BBCC). The comparisons of gene expressions for anthocyanin metabolic pathways in seed coats during seed development revealed differences in its metabolism among these species. Interestingly, the R2R3-MYB transcription factors MYB5 and TT2 were differentially expressed at all eight stages of seed coat development, indicating that they might be the key genes that caused the variation of the seed coat color. The expression curve and trend analyses of the seed coat development period showed that the main reason for the unexpressed copies of MYB5 and TT2 was likely gene silencing caused by gene structural variation. These results were valuable for the genetic improvement of Brassica seed coat color, and also provided new insights into gene multicopy evolution in Brassica polyploids.
