Gene Details:
- Gene ID:
- Gene Symbol: CsRuby1
- Gene Name: Citrus sinensis Ruby1
- Genome: Citrus sinensis Valencia genome v1.0 (HZAU)
- Species: Citrus sinensis
Functional Descriptions:
- The accumulation of anthocyanins in fruit peel of blood orange in response to light is regulated by the G-box (CACGTC) within the promoter of CsRuby1. On the other hand, cold-inducible accumulation of anthocyanins in blood orange is regulated by the LTR region of the retrotransposon-containing promoter of CsRuby1.
- Retrotransposon promoter of Ruby1 controls both light- and cold-induced accumulation of anthocyanins in blood orange.
- Cold-inducible accumulation of anthocyanins in blood orange is regulated by the LTR region of the retrotransposon-containing promoter of CsRuby1.
- Localization of key light-responsive elements in the CgRuby1 promoter.
- This study shows that CsMYB3 plays a repressor role in the regulation of anthocyanin biosynthesis and proposes an ‘activator-and-repressor’ loop model constituted by CsRuby1 and CsMYB3 in the regulation of anthocyanin biosynthesis in citrus.
- Our study elucidates the regulatory mechanism and evolutionary history of the Ruby2-Ruby1 cluster in citrus, which are unique and different from that found in Arabidopsis, grape or petunia.
