Systematic identification of R2R3-MYB S6 subfamily genes in Brassicaceae and its role in anthocyanin biosynthesis in Brassica crops.

ABSTRACT: The Brassicaceae family includes Arabidopsis thaliana, various vegetables and oil crops. The R2R3-MYB genes of the S6 subfamily are crucial for regulating anthocyanin biosynthesis, however, their systematic identification in Brassicaceae plants is still incomplete. Here, we systematically identified homologous genes of R2R3-MYB transcription factors from the S6 subfamily across 31 Brassicaceae species. A total of 92 homologous genes were identified, with species representation ranging from 0 to 10 genes per species. Phylogenetic analysis classified these homologous genes into six distinct groups. Notably, approximately 70% of the homologous genes were found within the G6 group, indicating a high degree of evolutionary conservation. Furthermore, a phylogenetic analysis was conducted on 35 h
