The rice Os02g0101500 was reported as OsHPR1 in 2014 [1] by researchers from China.

Figure 4. Subcellular localizations of GFP–HPR1 and GFP-HPR2 fusions in transgenic rice protoplasts.[1].
Gene Symbol
- Os02g0101500 <=> OsHPR1,HPR1
Function
- The researchers constructed over-expression of the OsHPR1 gene and RNA interference plants of OsHPR1 and OsHPR2 genes in rice.
- 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.
Expression
- Results from RT-PCR, western-blot and enzyme assays showed that HPR1 activity changed significantly in corresponding transgenic lines without any effect on HPR2 activity, which is the same for HPR2.
Subcellular Localization
- In the present study, the subcellular localization of OsHPR1 protein was first predicted to be located in the peroxisome and cytosol respectively.
- In agreement with the prediction of HPR1 localization, the spots of HPR1-GFP and PTS1-CFP fusions were quite similar in the co-transformation protoplast, indicating the subcellular localization of HPR1 protein is in the peroxisome.
