DhMYB2 and DhbHLH1 regulates anthocyanin accumulation activation of late biosynthesis genes in -type .

-type is a popular orchid with good ornamental and market value. Despite their popularity, molecular regulation of anthocyanin biosynthesis during flower development remains poorly understood. In this study, we systematically investigated the regulatory roles of the transcription factors DhMYB2 and DhbHLH1 in anthocyanins biosynthesis.
