- Key message
- Genetic complementation demonstrated that OsDET1 mutation conferred the enhanced Chl content in the Gc mutant leaf
- Here, we found that OsDET1 is essential for maintaining normal rice development
- In conclusion, our data suggest that OsDET1 plays an important role in maintaining normal development in rice, and mediates the crosstalk between ABA biosynthesis and ABA signaling pathways in rice
- OsDET1 Modulates the ABA Signaling Pathway and ABA Biosynthesis in Rice
- The repression of OsDET1 had detrimental effects on plant development, and we found that OsDET1 is involved in modulating ABA signaling in rice
- OsDET1 RNAi plants exhibited an ABA hypersensitivity phenotype
- Using yeast two-hybrid and BiFC assays, we determined that OsDET1 physically interacts with OsDDB1 and OsCOP10; OsDDA1 binds to the ABA receptors OsPYL5 and OsDDB1
- These findings suggest that OsDET1 deficiency disturbs the CDD complex, which is responsible for ABA receptor (OsPYL) degradation, eventually leading to ABA sensitivity in rice
- Additionally, OsDET1 also modulated ABA biosynthesis, as ABA biosynthesis was inhibited in OsDET1 RNAi plants and promoted in OE-OsDET1 plants
- These findings will enhance our understanding of the functional roles of OsDET1 and the CDD complex in embryogenesis and flavonoid biosynthesis in rice seeds
