CMDH — Zea mays

Summary

ZM00001EB045790 (CMDH, ZmCMDH) on maize chromosome 1 encodes a malate dehydrogenase with NAD-L-malate dehydrogenase and NADP+ L-malate dehydrogenase activity, belonging to the NAD-dependent eukaryotic malate dehydrogenase family. The gene is associated with C4 and CAM photosynthesis, downregulation of photosynthesis, oxidative phosphorylation, and energy homeostasis, as well as malate, oxaloacetate, pyruvate, and NAD metabolism. It has been linked to numerous agronomic traits including grain filling period, grain size, ear number, tiller number, leaf area duration, crop growth rate, water use efficiency, heat tolerance, cold stress response, chlorophyll content, photosynthetic ability, rubisco content, sucrose content, root volume and length, and heterosis. The product localises to chloroplast stroma, plastid, apoplast, cell wall, vacuole, ER, and Golgi. Related genes in other species are linked to starch biosynthesis and grain weight.
