Os06g0245600

The rice Os06g0245600 was reported as RPL1 in 2011 by researchers from China.

Annotated Information

Gene Symbol

• Os06g0245600 <=> OsRPL1,RPL1

Function

• HSF binding protein (HSBP) is reported to modulate the function of HSF by binding to their trimer and hence to regulate HSR.
• OsHSBP1 and OsHSBP2 play important role in the regulation of the HSR and seed development of rice.

Phenotypic analysis

• Both OsHSBP1 and OsHSBP2 were also important for seed development, as their knock-down lines were associated with significant seed abortion.
• The thermotolerance assay revealed that OsHSBP1 and OsHSBP2 are negative regulators of HSR and involved in acquired thermotolerance but not in basal thermotolerance since their over-expression transgenic lines pre-heated at sublethal temperature, showed significantly decreased seedling survival after heat shock treatment.
• Furthermore, antioxidant activity and gene expression of catalase and peroxidase was significantly increased in knock-down transgenic seedlings of OsHSBP1 and OsHSBP2 after heat stress compared with the wild type.

Expression

• Both OsHSBP1 and OsHSBP2 expressed ubiquitously in all tissues under normal growth conditions while their expression levels were significantly increased during recovery after heat shock treatment.

Subcellular localization

• Subcellular localization analysis revealed the cytosol-nuclear localization of both OsHSBP1 and OsHSBP2 in onion epidermal cells.
