Nitrates 16-23 phosphoenolpyruvate carboxylase 2 Triticum aestivum 243-274 12228402-6 1995 In vivo labeling of wheat-leaf PEPC by feeding 32P-labeled orthophosphate showed that PEPC from light plus KNO3 tissue was substantially more phosphorylated than the enzyme in the dark minus-nitrate immunoprecipitates.
