Gene Details:
- Gene ID: Cs3g17870
- Gene Symbol: CsHB5
- Gene Name:
- Genome: Reference genome of sweet orange
- Species: Citrus sinensis
Functional Descriptions:
- CsHB5, a positive regulator of ABA and carotenoid-driven processes, activates the expression of CsbZIP44 by binding to its promoter.
- The transcriptional regulatory module CsHB5-CsbZIP44 positively regulates abscisic acid-mediated carotenoid biosynthesis in citrus.
- Our research indicates that CsHB5, a positive regulator of ABA and carotenoid-driven processes, activates the expression of CsbZIP44 by binding to its promoter.
- CsHB5-CsbZIP44 precisely modulates ABA signal-mediated carotenoid metabolism, providing an effective strategy for quality improvement of citrus fruit and other crops.
- Citrus transcription factor CsHB5 regulates abscisic acid biosynthetic genes and promotes senescence.
- Overexpression of CsHB5 in citrus calli upregulated the expression of ABA- and reactive oxygen species (ROS)-related genes, and significantly increased the content of ABA and hydrogen peroxide (H2O2), whereas silencing CsHB5 in citrus calli downregulated the expression of ABA-related genes.
