PPC — Zea mays

Summary

ZM00001EB383680 (ZmPPC, also known as PPC) encodes a phosphoenolpyruvate carboxylase (EC 4.1.1.31) with phosphoenolpyruvate carboxylase activity. This maize gene on chromosome 9 is associated with NADP-malic enzyme C4 photosynthesis, CAM photosynthesis, and regulation of lipogenesis, as well as traits including grain moisture content, leaf weight, radiation use efficiency, carbon isotope discrimination, anthesis-silking interval, ear length, amylose content, and nitrogen and phosphorus concentrations. It is linked to root growth, salt stress response, seed development, photosynthesis efficiency, and starch and sucrose accumulation. The encoded protein localizes to the cytosol, chloroplast stroma, mitochondria, and plasmodesmata. Related genes in other species are linked to salt stress tolerance, phosphate deficiency response, and nitrate response.
