Gene Details:

  • Gene ID: DCAR_030904
  • Gene Symbol: DcCCD4
  • Gene Name: Carotenoid cleavage dioxygenase 4
  • Genome:
  • Species: Daucus carota

Functional Descriptions:

  • DcCCD4 catalyzes the degradation of α-carotene and β-carotene to affect carotenoid accumulation and taproot color in carrot.
  • In this study, through expression analysis, we found that the expression level of DcCCD4 was significantly higher in the taproot of white carrot (low carotenoid content) than orange carrot (high carotenoid content).
  • The overexpression of DcCCD4 in orange carrots caused the taproot color to be pale yellow, and the contents of α- and β-carotene decreased sharply.
  • The number of colored chromoplasts in the taproot cells of transgenic carrots overexpressing DcCCD4 was significantly reduced compared with that in normal orange carrots.
  • Results showed that DcCCD4 affects the accumulation of carotenoids through cleavage of α- and β-carotene in carrot taproot.
