Gene Details:
- Gene ID: Cs5g31400
- Gene Symbol: CsTT8
- Gene Name:
- Genome:
- Species: Citrus sinensis
Functional Descriptions:
- CsTT8 regulates anthocyanin accumulation in blood orange through alternative splicing transcription.
- A homologous gene of basic-helix–loop–helix AtTT8 in Arabidopsis thaliana was identified in juice sac cells of pulp tissues from blood orange (Citrus sinensis cv ‘Tarocco’), which was designated as CsTT8 in this study.
- Our findings suggest that TT8, rather than dysfunctional Δ15-TT8, is possibly involved in modulating anthocyanin biosynthesis and its transport into vacuoles by proton gradients.
- Increased mRNA levels of the dysfunctional alternative splicing transcript may act as a negative feedback to downregulate TT8 expression and limit anthocyanin accumulation in blood oranges.
- CsTT8 is involved in citrus ripening by regulating abscisic acid and gibberellin metabolisms.
