WebOct 18, 2024 · Anthocyanin biosynthesis genes are transcriptionally regulated by the MBW ternary complex of R2R3-MYB, basic helix-loop-helix (bHLH), and tryptophan aspartic (WD)-repeat proteins (Albert et al., 2014 ). WebMar 15, 2024 · Author summary Anthocyanins, a class of flavonoids distributed ubiquitously in the plant kingdom, are induced by environmental stimuli and developmental signals, such as high light and sucrose. It is well established that anthocyanin accumulation is regulated by the MYB-bHLH-WD40 (MBW) protein complex in plants.
WebMar 6, 2012 · Anthocyanin production is controlled primarily at the transcriptional level. In a range of angiosperm species a common regulatory complex composed of Myb, basic helix-loop-helix (bHLH) transcription factors, and a WD repeat protein has been shown to control anthocyanin biosynthesis. WebSix anthocyanin-activating MYB genes, designated PcMYB10.1 to PcMYB10.6, were isolated based on RNA-Seq data from leaves of cv. Ziyeli. Of these PcMYB10 genes, five (PcMYB10.1 through PcMYB10.5) show distinct spatial and temporal expression patterns, while the PcMYB10.6 gene is highly expressed in all the purple-coloured organs of cv.
