Gene Details:

Functional Descriptions:

  • In addition, OsOAT-overexpressing plants showed significantly increased tolerance to oxidative stress.
  • An ornithine delta-aminotransferase gene OsOAT confers drought and oxidative stress tolerance in rice.
  • We confirmed that OsOAT is a direct target of the stress-responsive NAC transcription factor SNAC2.
  • Overexpression of OsOAT caused significantly increased delta-OAT activity and Pro accumulation under normal growth conditions.
  • Both ABA-dependent and ABA-independent pathways contributed to the drought-induced expression of OsOAT.
  • Overexpression of the OsOAT gene in rice resulted in significantly enhanced drought and osmotic stress tolerance.
  • OsOAT is responsive to multiple stresses and phytohormone treatments.
  • In the OsOAT mutant, metabolic abnormality induced by nitrogen deficiency in floret causes malformed glumes, incapable glume opening and anther indehiscence.
  • Therefore, OsOAT is crucial for nitrogen reutilization and plays a critical role in floret development and seed setting in rice.
  • OsOAT mutant was identified as a temperature-sensitive male sterile mutant with deformed floral organs and seedlings sensitive to cold stress.
  • Ornithine 未-aminotransferase OsOAT is critical for male fertility and cold tolerance during rice plant development.
  • Moreover, indica varieties carrying WYG-type OsOAT generally have higher seed-setting rates than those carrying HHZ-type OsOAT under cold stress at reproductive stage, highlighting the favorable selection for WYG-type OsOAT during domestication and breeding to cope with low temperatures.
  • Comparative transcriptome analysis showed that OsOAT mutation and cold treatment of the wild-type plant led to similar changes in the global gene expression profiles in anthers.
  • OsOAT genes in indica rice Huanghuazhan (HHZ) and japonica rice Wuyungeng (WYG) are different in gene structure and response to cold.
