33178234-4	2020	Measurements of the flux of 13CO2 through photosynthetic metabolism revealed a significant increase in the incorporation of 13C into malate, consistent with increased fixation of 13CO2 via PEP carboxylase in lines expressing the maize PEPC enzyme.	13co2	179-184	phosphoenolpyruvate carboxylase 1	Zea mays	235-239

33178234-8	2020	There was evidence of 13C labeling of aspartate indicating 13CO2 fixation into oxaloacetate by PEPC and conversion to aspartate by the endogenous aspartate aminotransferase activity.	13co2	59-64	phosphoenolpyruvate carboxylase 1	Zea mays	95-99
