Gene Details:

  • Gene ID:
  • Gene Symbol: CrBCH2
  • Gene Name: β-carotene hydroxylases 2
  • Genome:
  • Species: Citrus reticulata

Functional Descriptions:

  • An R2R3-MYB transcription factor represses the transformation of α- and β-branch carotenoids by negatively regulating expression of CrBCH2 and CrNCED5 in flavedo of Citrus reticulate.
  • A comprehensive analysis of developing and harvested fruits indicated that reduced expression of β-carotene hydroxylases 2 (CrBCH2) and 9-cis-epoxycarotenoid dioxygenase 5 (CrNCED5) was responsible for the delay in the transformation of α- and β-carotene and the biosynthesis of ABA.
  • Report that the transformation of α- and β- branch carotenoids was indeed delayed in MT and that an MYB TF (CrMYB68) can repress the transformation of α- and β-branch carotenoids by directly suppressing the expression of CrBCH2 and CrNCED5.
  • CrMYB68 bound to the promoters of CrBCH2 and CrNCED5 and significantly inhibited their expression.
