Activities of C4 photosynthetic pathway enzymes in different bread wheat genotypes under field conditions

Activities of C4 photosynthetic pathway enzymes in different bread wheat genotypes under field conditions

The activities of key C4 photosynthetic enzymes including phosphoenolpyruvate carboxylase (PEPcase), NADP-malic enzyme (NADP-ME), malate dehydrogenase (MDH) and pyruvate phosphate dikinase (PPDK) were assayed in flag leaves at three major growth stages (heading, anthesis and grain filling) among 5...
