Phosphoenolpyruvate carboxylase (PEPC) catalyzes the initial fixation of CO2 in C4 plants. Under the control of the rice Rubisco small subunit promoter, cDNA of a C4 SiPPC gene cloned from Seteria italica was introduced into Japonica rice by Agrobacterium-mediated transformation. Integration of the gene was confirmed by PCR analysis. RT-PCR showed(More)
Abiotic stresses induce phosphoenolpyruvate carboxylase (PEPC) expression in C3 plants which suggests PEPC function in plant adaptation to stresses. Here, we studied the response of photosynthesis to short-term drought stress in rice seedlings overexpressing C4 PEPC from maize and millet. The transgenic lines exhibited 1.2–5.5 fold of PEPC activities than(More)
