Annotated Information
Gene Symbol
- Os09g0522200 <=> OsDREB1A,CBF3, OsCBF3, OsDREB1A/OsCBF3, ERF24, OsERF24
Function
- The transcription factors dehydration-responsive element-binding protein 1s (DREB1s)/C-repeat-binding factors (CBFs) specifically interact with the DRE/CRT cis-acting element and control the expression of many stress-inducible genes in Arabidopsis.
- The genes for DREB1 orthologs, OsDREB1A and OsDREB1B from rice, are induced by cold stress, and overexpression of DREB1 or OsDREB1 induced strong expression of stress-responsive genes in transgenic Arabidopsis plants, resulting in increased tolerance to high-salt and freezing stresses.
- OsDREB1A contained an open reading frame of 238 amino acids and encoded a putative protein with a predicted molecular mass of 25.6 kDa.
Expression
- The expression patterns of the OsDREB genes were analyzed by RNA-gel blot hybridization.
- The OsDREB1A genes were not responsive to exposure to ABA but they were induced within 40 min after exposure to cold stress.
- OsDREB1A was also induced within 5 h after salt treatment and was transiently expressed in wounded seedlings.
Evolution
- The analyses of the similarities of the ERF/AP2 domains of the OsDREB proteins and compared them with those in Arabidopsis and other genera.
- The OsDREB1 proteins were classified into the A-1 (DREB1/CBF) subgroup which is one of five groups of ERF/AP2-related proteins– AP2 subfamily,RAV subfamily, DREB subfamily, ERF subfamily, and one very specific gene, AL079349.
- The DREB1-type ERF/AP2 domains in the three monocots were closely related to each other but distant from those in the dicots.
