Annotated Information
Gene Symbol
- Os02g0698000 <=> SBPase,OsSBPase,OsPrk
Function
- Under high temperature stress, SBPase maintained the activation of ribulose-1,5-bisphosphate carboxylase-oxygenase (Rubisco) by preventing the sequestration of Rubisco activase to the thylakoid membranes from the soluble stroma fraction and thus enhanced the tolerance of CO2 assimilation to high temperature stress.
- overexpression of SBPase might be an effective method for enhancing high temperature tolerance of plants.
Phenotypic analysis
- Activity of the Calvin cycle enzyme sedohep-tulose-1,7-bisphosphatase (SBPase) was increased by overexpression of a rice plants 9,311 (Oryza sativa L.) cDNA in rice plants zhonghua11 (Oryza sativa L.).
- The genetic engineering enabled the plants to accumulate SBPase in chloroplasts and resulted in enhanced tolerance to high temperature stress during growth of young seedlings.
- Moreover, CO 2 assimilation of transgenic plants was significantly more tolerant to high temperature than that of wild-type plants.
