The rice Os01g0228600 was reported as OsHPR2 in 2014 by researchers from China.

Annotated Information

Gene Symbol

• Os01g0228600 <=> OsHPR2,HPR2

Function

• The researchers constructed over-expression of the OsHPR1 gene and RNA interference plants of OsHPR1 and OsHPR2 genes in rice.
• HPR1 activity changed significantly in corresponding transgenic lines without any effect on HPR2 activity, which is the same for HPR2.
• The phenotypes of all transgenic lines were determined in ambient air and CO 2 -elevated air. The phenotype typical of photorespiration mutants were observed only where activity of both HPR1 and HPR2 were down-regulated in the same line.
• Double deletion of OsHPR1 and OsHPR2 genes significantly reduces plant growth under normal photorespiration condition
• These findings demonstrate that two hydroxypyruvate reductases encoded by OsHPR1 and OsHPR2 are involved in photorespiratory metabolism in rice.
