cultivar group presenting different coloring mechanisms. In recent years, the discovery of MybA-related genes, an important regulatory gene family, has increased our understanding of anthocyanin biosynthesis. Kobayashi et al. (2002) reported that MybA

DMTU treatment. We therefore concluded that the combination of LT and DMTU regulated anthocyanin content at the transcriptional level by modulating the expression of late biosynthesis-related genes. Effects of LT and DMTU on chlorophyll fluorescence
