Gene Details:

  • Gene ID:
  • Gene Symbol: CrWRKY42
  • Gene Name: WRKY transcription factor 42
  • Genome:
  • Species: Citrus clementina

Functional Descriptions:

  • Transcription factor CrWRKY42 coregulates chlorophyll degradation and carotenoid biosynthesis in citrus.
  • CrWRKY42 directly bound to the promoter of β-carotene hydroxylase 1 (CrBCH1) and activated its expression.
  • Overexpression and interference of CrWRKY42 in citrus calli demonstrated that CrWRKY42 promoted carotenoid accumulation by inducing the expression of multiple carotenoid biosynthetic genes.
  • The overexpression and silencing of CrWRKY42 in citrus fruits indicated that CrWRKY42 positively regulated chlorophyll degradation and carotenoid biosynthesis by synergistically activating the expression of genes involved in both pathways.
  • Our data revealed that CrWRKY42 acts as a positive regulator of chlorophyll degradation and carotenoid biosynthesis to alter the conversion of citrus fruit color.
