Function
- Glycine decarboxylase complex (GDC) is a multi-protein complex, comprising P-, H-, T- and L-protein subunits, which plays a major role in photorespiration in plants.
- The OsGDCH is a typical photorespiratory gene
- Knockdown of the OsGDCH causes senescence of rice plants under ambient CO2
Phenotypic analysis
- Under high CO 2 (0.8%) conditions, in which photorespiration is inhibited, no substantial difference in phenotype was seen between the OsGDCH-RNAi plants and WT plants.
- However, after growth under ambient CO 2 (0.04%; photorespiratory conditions), obvious changes were observed in the SSPs. Yellowish spots resembling necrotic lesions appeared on the leaves after several hours of exposure to ambient CO2.
- As time progressed, the plants underwent a progressive change in leaf colour from green to yellow, usually starting from the tips or the margins and spreading towards the leaf base (Fig. 2).
- This phenotype mimicked a senescence syndrome (Quirino et al. 2000). The syndrome became more severe as time progressed, leading to a complete cessation of growth and finally to the death of SSPs, whereas these phenotypes were not seen in either the MSPs or WT (Fig. 2a–f).
