Gene Symbol
- Os04g0610400 <=> OsAP2-39, OsERF#077, OsERF077, OsERF77, AP2/EREBP#149, AP2/EREBP149
Function
- The phytohormone ethylene is a key signaling molecule that regulates a variety of developmental processes and stress responses in plants. Transcriptional modulation is a pivotal process controlling ethylene synthesis, which further triggers the expression of stress-related genes and plant adaptation to stresses.
- The APETALA-2-Like Transcription Factor OsAP2-39 Controls Key Interactions between Abscisic Acid and Gibberellin in Rice.
- ERF protein OsAP2-39 controls the ABA/gibberellins balance in rice, which in turn regulates plant growth and seed production.
- OsAP2-39 links the ABA production and GA deactivation processes which results in ABA/GA balance and homeostasis[1][2].
Phenotypic analysis
- Controlling the expression level of OsAP2-39 which includes an APETALA 2 (AP2) domain leads to phenotypic changes in rice.
- Overexpression of OsAP2-39 leads to a reduction in yield by decreasing the biomass and the number of seeds in the transgenic rice lines.
- Global transcriptome analysis of the OsAP2-39 overexpression transgenic rice revealed the upregulation of a key Abscisic Acid (ABA) biosynthetic gene OsNCED-I which codes for 9-cis-epoxycarotenoid dioxygenase and leads to an increase in the endogenous ABA level.
Expression
- overexpression of OsERF3/OsAP2-39 suppressed ethylene synthesis.
- In vivo and in vitro analysis showed that the expression of both OsNCED-1 and EUI are directly controlled by OsAP2-39.
