- Os07g0152900 <=> OsGLO4,GLO4
Function
- Glycolate oxidase (GLO) encoded by OsGLO4 is a key enzyme for photorespiration in plants.
- suppression of GLO genes causes photosynthetic inhibition, and the accumulated glycolate with the deactivated Rubisco is likely involved in the regulation.
Phenotypic analysis
- The researchers have generated the transgenic rice (Oryza sativa) plants with GLO being constitutively silenced, and conducted the physiological and biochemical analyses on these plants to explore the regulatory mechanism.
- When GLO was downregulated, the net photosynthetic rate (Pn) was reduced and the plant growth was correspondingly stunted. Surprisingly, glyoxylate, as a product of the GLO catalysis, was accumulated in response to the GLO suppression, like its substrate glycolate.
- Furthermore, the glyoxylate content was found to be inversely proportional to the Pn while the Pn is directly proportional to the Rubisco activation state in the GLO-suppressed plants.
