- Key message
- When excessive active BR is applied, the hormone mostly induces GA inactivation through upregulation of the GA inactivation gene GA2ox-3 and also represses BR biosynthesis, resulting in decreased hormone levels and growth inhibition.
- Mutation in OsGA2ox3 weakened ethylene-induced GA inactivation and reduced the ethylene sensitivity of the root

- d18~OsGA3ox2, GA2OX3~OsGA2OX3, OsDOG, a gibberellin-induced A20/AN1 zinc-finger protein, negatively regulates gibberellin-mediated cell elongation in rice, Additional GA(1) and real-time PCR quantitative assay analyses confirmed that the decrease of GA(1) in the overexpression lines resulted from reduced expression of GA3ox2 and enhanced expression of GA2ox1 and GA2ox3
- GA2OX3~OsGA2OX3, OsGA2ox1, OsDOG, a gibberellin-induced A20/AN1 zinc-finger protein, negatively regulates gibberellin-mediated cell elongation in rice, Additional GA(1) and real-time PCR quantitative assay analyses confirmed that the decrease of GA(1) in the overexpression lines resulted from reduced expression of GA3ox2 and enhanced expression of GA2ox1 and GA2ox3
- GA2OX3~OsGA2OX3, OsMADS57, Rice transcription factor OsMADS57 regulates plant height by modulating gibberellin catabolism., Expectedly, the transcript levels of OsGA2ox3, encoding GAs deactivated enzyme, were significantly enhanced in OsMADS57 knockdown plants
- GA2OX3~OsGA2OX3, OsMADS57, Rice transcription factor OsMADS57 regulates plant height by modulating gibberellin catabolism., More importantly, dual-luciferase reporter assay and electrophoretic mobility shift assay showed that OsMADS57 directly regulates the transcription of OsGA2ox3 as well as EUI1 through binding to the CArG-box motifs in their promoter regions
- GA2OX3~OsGA2OX3, OsNAC109, OsNAC109 regulates senescence, growth and development by altering the expression of and phytohormone-associated genes in rice., It was confirmed that OsNAC109 could directly regulate the expression of OsNAP, OsNYC3, OsEATB, OsAMTR1, OsZFP185, OsMPS and OsGA2ox3 by targeting to the highly conserved cis-element CNTCSSNNSCAVG except OsSAMS1
- GA2OX3~OsGA2OX3, OsGA2ox1, Orchestration of ethylene and gibberellin signals determines primary root elongation in rice., Further investigations unraveled that ethylene signaling transcription factor ETHYLENE INSENSITIVE3-LIKE 1 OsEIL1 activates the expression of the GA metabolism genes GIBBERELLIN 2-OXIDASE 2 (OsGA2ox1), OsGA2ox2, OsGA2ox3, and OsGA2ox5, thereby deactivating GA activity, inhibiting cell proliferation in the root meristem, and ultimately gradually inhibiting primary root growth
- GA2OX3~OsGA2OX3, OsEIL1~MHZ6, Orchestration of ethylene and gibberellin signals determines primary root elongation in rice., Further investigations unraveled that ethylene signaling transcription factor ETHYLENE INSENSITIVE3-LIKE 1 OsEIL1 activates the expression of the GA metabolism genes GIBBERELLIN 2-OXIDASE 2 (OsGA2ox1), OsGA2ox2, OsGA2ox3, and OsGA2ox5, thereby deactivating GA activity, inhibiting cell proliferation in the root meristem, and ultimately gradually inhibiting primary root growth
- GA2OX3~OsGA2OX3, OsEIL1~MHZ6, Orchestration of ethylene and gibberellin signals determines primary root elongation in rice., Genetic analysis revealed that OsGA2ox3 functions downstream of OsEIL1
