Impaired Photorespiratory Metabolism Underlies the Decline in CO2 Assimilation Induced by Alternative Oxidase Inhibition in Rumex K-1 Leaves
Photosynthetic carbon assimilation under photorespiratory conditions requires tight coordination between chloroplast electron transport and mitochondrial redox metabolism, yet the contribution of mitochondrial alternative oxidase (AOX) remains unresolved. Using 1 mM salicylhydroxamic acid (SHAM) to inhibit the AOX path...
