摘要: Flowering Chinese cabbage (Brassica rapa var. parachinensis) is one of the most popular vegetables in the south of China. As an antioxidant, anthocyanin is an important quality trait in vegetables, and the gene related to anthocyanin biosynthesis in purple flowering Chinese cabbage is also important. In this study, two flowering Chinese cabbage with extreme colors in the stem were used as materials for transcriptome analysis. RNA-seq analysis showed that 6811 differentially expressed genes (DEGs) were identified, including 295 transcription factors. Phenylpropanoid biosynthesis, flavone and flavanol biosynthesis, and flavonoid biosynthesis pathways were found to be significantly enriched in the purple flowering Chinese cabbage. A total of 25 DEGs associated with anthocyanin biosynthesis were found at a higher expression in purple flowering Chinese cabbage than in green flowering Chinese cabbage. Bioinformatics analysis shows that BrMYB114 is a candidate gene for the regulation of anthocyanin biosynthesis, and heterologous expression analysis of BrMYB114 in Nicotiana benthamiana indicates that BrMYB114 functions in anthocyanin biosynthesis. Therefore, our findings provide vital evidence for elucidating the molecular mechanism in the purple stem in flowering Chinese cabbage.
