NADP-MDH — Zea mays

Summary

ZM00001EB038930, designated ZmNADP-MDH on maize chromosome 1, encodes a protein with malate dehydrogenase (NADP+) activity (EC 1.1.1.82) and contains domains including Malate_DH_NADP-dep_pln, Malate_DH_type2, and NAD(P)-bd_dom_sf. The gene is associated with C4 photosynthesis, phloem loading, light absorption, and other biological processes such as redox signal response, hormone metabolism, programmed cell death, and phosphorus utilization. Its product localises to the thylakoid, chloroplast stroma, envelope, and other compartments. ZmNADP-MDH is linked to agronomically important traits including grain yield, biomass yield, plant height, root volume and length, chlorophyll content, net photosynthetic rate, water use efficiency, and drought tolerance. It is also associated with responses to flooding, cold, high light, and disease resistance. Related genes in other species link the family to chloroplast malate metabolism and redox homeostasis.
