Expression analysis of correlative regulatory factors of anthocyanin in ‘Cuihongli’ and ‘Qiangcuili’
View through CrossRef
MYB10, bHLH and WD40 are correlative regulatory factors of anthocyanin. In this paper, the expression of MYB10, bHLH and WD40 in the peel and the pulp of two plum cultivars were analyzed with the materials of ‘Cuihongli’ and ‘Qiangcuili’. The results showed that, with the development of the fruit of ‘Cuihongli’, the expression of MYB10 in the peel was downregulated firstly then upregulated, and the expression of MYB10 was not detected in the flesh of ‘Cuihongli’s pulp and the peel and the pulp of the ‘Qiangcuili’. The expression of bHLH and WD40 showed that the they had no significant correlation with the accumulation of anthocyanin in the two cultivars. It is suggested that the deletion of MYB10 gene expression result in the lack of anthocyanin in the flesh of ‘Qiangcuili’ .
