The rice Os03g0315400 was reported as OsMYB2 in 2012 [1] by researchers from China.
Contents
Annotated Information
Gene Symbol
- Os03g0315400 <=> OsMYB2,MYB2
Function
- OsMYB2 encodes a stress-responsive MYB transcription factor.
- OsMYB2 plays a regulatory role in tolerance of rice to salt, cold, and dehydration stress.
Phenotypic analysis
- No difference in growth and development between the OsMYB2-overexpressing and wild-type plants was observed under normal growth conditions, but the OsMYB2-overexpressing plants were more tolerant to salt, cold, and dehydration stresses and more sensitive to abscisic acid than wild-type plants.
- The OsMYB2-overexpressing plants accumulated greater amounts of soluble sugars and proline than wild-type plants under salt stress. Overexpression of OsMYB2 enhanced up-regulation of genes encoding proline synthase and transporters. The OsMYB2-overexpressing plants accumulated less amounts of H 2 O 2 and malondialdehyde.
- The enhanced activities of antioxidant enzymes, including peroxidase, superoxide dismutase, and catalase, may underlie the lower H2O2 contents in OsMYB2-overexpressing plants.
- There was greater up-regulation of stress-related genes, including OsLEA3, OsRab16A, and OsDREB2A, in the OsMYB2-overexpressing plants. Microarray analysis showed that expression of numerous genes involving diverse functions in stress response was altered in the OsMYB2-overexpressing plants.
Expression
- Expression of OsMYB2 was up-regulated by salt, cold, and dehydration stress.
Subcellular localization
- OsMYB2 was localized in the nucleus with transactivation activity.
