Fig. 8: MdMYB1 activates transcription of MdGSTF6 to enhance its expression.
From: MdGSTF6, activated by MdMYB1, plays an essential role in anthocyanin accumulation in apple
a Effects of MdMYB1, MdbHLH3, and MdbHLH33 individually and in combination on the promoter activity of MdGSTF6 in a luciferase reporter assay. b β-Glucuronidase (GUS) staining of pMdGSTF6::GUS and pMdGSTF6::GUS plus 35S::MdMYB1-HA. c GUS activity in apple calli as labeled. GUS activity was measured three times with three replicates
