The rice Os04g0459000 was reported as OsEATB in 2011 [1] by researchers from China. [1]

Annotated Information
Function
- Plant height is a decisive factor in plant architecture. Rice (Oryza sativa) plants have the potential for rapid internodal elongation, which determines plant height. A large body of physiological research has shown that ethylene and gibberellin are involved in this process.
- The APETALA2 (AP2)/Ethylene-Responsive Element Binding Factor (ERF) family of transcriptional factors is only present in the plant kingdom.
- OsEATB reduces rice plant height and panicle length at maturity, promoting the branching potential of both tillers and spikelets.
- OsEATB Is a Novel Rice AP2/ERF
- OsEATB Negatively Regulates Ethylene-Induced Enhancement of GA Responsiveness by Reducing GA Biosynthesis
- OsEATB Regulates Rice Yield Components through the Promotion of Tillering and Panicle Branching
Phenotypic analysis
- Overexpression of OsEATB Decreases the Endogenous GA Level in Rice
Expression
- OsEATB Expression Is Negatively Regulated by Ethylene, ABA, and Abiotic Stress in Rice
- Ectopic expression of OsEATB showed that the cross talk between ethylene and gibberellin, which is mediated by OsEATB, might underlie differences in rice internode elongation.
- Analyses of gene expression demonstrated that OsEATB restricts ethylene-induced enhancement of gibberellin responsiveness during the internode elongation process by down-regulating the gibberellin biosynthetic gene, ent-kaurene synthase A.
