Fig. 7From: Betalain biosynthesis in red pulp pitaya is regulated via HuMYB132: a R-R type MYB transcription factorSchematic illustration of HuMYB132 involved in pitaya betalain biosynthesis. A, HuMYB132 activates the transcription of HuADH1, HuCYP76AD1–1, and HuDODA1 by binding to the MRE and MBS elements in their promoters on pitaya chromosome 3. B, Betalains are synthesized in pitaya all chromosomes by GT genes and/or spontaneous reactionBack to article page
