Gene Symbol
- Os11g0167800 <=> OsAsr1,Asr1
Function
- OsAsr1' gene play an important role during temperature stress, and that this gene can be used for generating plants with enhanced cold tolerance.
Phenotypic analysis
- For transgenic rice plants that over-expressed full-length OsAsr1 cDNA in the sense orientation, the Fv/Fm values for photosynthetic efficiency were about 2-fold higher than those of wild type-segregating plants after a 24-h cold treatment.
- Seedlings exposed to prolonged low temperatures were more tolerant of cold stress, as demonstrated during wilting and regrowth tests.
- Interestingly,OsAsr1 was highly expressed in transgenic rice plants expressing the C-repeat/dehyhdration responsive element binding factor 1 (`_cN), suggesting the regula-
tion of OsAsr1by CBF1.
Expression
- Low-temperature stress increased mRNA levels of OsAsr1 in both vegetative and reproductive organs.
- In situ analysis showed that OsAsr1 transcript was preferentially accumulated in the leaf mesophyll tissues and parenchyma cells of the palea and lemma.
