The rice Os04g0434800 was reported as OsAPX7 in 2014 [1] by researchers from Brazil.

Annotated Information
Gene Symbol
- Os04g0434800 <=> OsAPX7,APX7,sAPX
Function
- OsAPX7 encode chloroplastic APXs (chlAPXs).
Phenotypic analysis
- The chlAPX knockdown plants were affected more severely than the non-transformed (NT) plants in the activity and structure of PSII and CO2 assimilation in the presence of MV.
- Although MV induced significant increases in pigment content in the knockdown plants, the increases were apparently not sufficient for protection. Treatment with HL also caused generalized damage in PSII in both types of plants.
- The knockdown and NT plants exhibited differences in photosynthetic parameters related to efficiency of utilization of light and CO2.
- The knockdown plants overexpressed other antioxidant enzymes in response to the stresses and increased the GPX activity in the chloroplast-enriched fraction.
Expression
- OsAPX7 gene was also upregulated in double mutants submitted to abiotic stress. This upregulation suggests that in spite of the knockdown of this gene, it is still able to respond to the stress in an effort to compensate for its own post-transcriptional silencing triggered by the RNAi construct.
- However, the expression of OsAPX7 is lower in the knockdown plants than it is in the NT plants.
