The rice Os03g0693700 was reported as Osoxo4 in 2013 by researchers from Japan.

Annotated Information

Gene Symbol

• Os03g0693700 <=> Osoxo4,oxo4

Phenotypic analysis

• Overexpression of the *Osoxo4* gene in transgenic plants showed higher enzyme activity of oxalate oxidase (OxO) than nontransgenic control plants, which was visualized by histochemical assays and sodium dodecylsulphate-polyacrylamide gel electrophoresis (SDS-PAGE).
• Transgenic rice leaves were more tolerant than control rice leaves to exogenous OA. Transgenic plants showed a higher level of expression of other defence-related genes in response to pathogen infection.
• More importantly, transgenic plants exhibited significantly enhanced durable resistance to R. solani. The overexpression of Osoxo4 in rice did not show any detrimental phenotypic or agronomic effect.
• The transgenic Osoxo4-overexpressing rice lines and nontrans-genic control plants were subjected to bioassay with a virulent Hyderabad isolate of R. solani AG1-1A. The transgenic lines showed an increased level of sheath blight resistance, as demon- strated by a low sheath blight score in comparison with nontransgenic control plants.
