Gene Details:

• MSU gene ID: LOC_Os03g05590
• RAPdb gene ID: Os03g0150200
• Gene Symbol: OsAP23
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• In this study, the rice OsAP23 gene, which encodes an AP2/ERF transcription factor, was isolated from rice using a yeast-one-hybrid system.
• The OsAP23 transcription factor belongs to the B3 group of the ERF subfamily.
• Germination results for transgenic Arabidopsis plants hosting the OsAP23 gene revealed greater inhibition at the germination and seedling stages with increasing concentration of NaCl compared to the wild-type plants.
• In addition, following exposure to high salt concentrations, several stress-responsive regulatory genes were induced to a significantly greater extent in the wild-type lines compared with lines that over-express OsAP23.
• These results suggested that OsAP23 might be a negative regulator of the salt stress response in higher plants.
• Exogenous ABA also reduced the rate of germination of transgenic Arabidopsis seeds that over-express OsAP23 compared with wild-type Arabidopsis seeds.
