- Key message
- Gibberellin 20-oxidase gene OsGA20ox3 regulates plant stature and disease development in rice
- Transgenic plants overexpressing OsGA20ox3 showed phenotypes similar to those of the 17S-14 mutant, and the RNA interference (RNAi) lines that had decreased OsGA20ox3 expression exhibited a semidwarf phenotype.
- Expression of OsGA20ox3 was detected in the leaves and roots of young seedlings, immature panicles, anthers, and pollens, based on beta-glucuronidase (GUS) activity staining in transgenic plants expressing the OsGA20ox3 promoter fused to the GUS gene.
- The OsGA20ox3 RNAi lines showed enhanced resistance against rice pathogens Magnaporthe oryzae (causing rice blast) and Xanthomonas oryzae pv. oryzae (causing bacterial blight) and increased expression of defense-related genes.

- DCM1~SAW1, OsGA20ox3~GA20ox3, A novel CCCH-type zinc-finger protein SAW1 activates OsGA20ox3 to regulate gibberellin homeostasis and anther development in rice., A novel CCCH-type zinc-finger protein SAW1 activates OsGA20ox3 to regulate gibberellin homeostasis and anther development in rice.
- DCM1~SAW1, OsGA20ox3~GA20ox3, A novel CCCH-type zinc-finger protein SAW1 activates OsGA20ox3 to regulate gibberellin homeostasis and anther development in rice., SAW1 encodes a novel nucleus-localizing CCCH-tandem zinc finger protein, and this protein could directly bind to the promoter region of the GA synthesis gene OsGA20ox3 to induce its anther-specific expression
- DCM1~SAW1, OsGA20ox3~GA20ox3, A novel CCCH-type zinc-finger protein SAW1 activates OsGA20ox3 to regulate gibberellin homeostasis and anther development in rice., In the saw1 anther, the significantly decreased OsGA20ox3 expression resulted in lower bioactive GA content, which in turn caused the lower expression of the GA-inducible anther-regulator gene OsGAMYB
