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.
