NDC1 — Zea mays

Summary

ZM00001EB373110 (ZmNDC1) on maize chromosome 9 encodes a protein with NADH dehydrogenase (ubiquinone) activity (EC 1.6.5.12) and additional hydrolase, lyase, and isomerase activities, containing NADH-Q oxidoreductase and alpha/beta hydrolase domains. The gene is associated with oxidative phosphorylation, aerobic electron transport chain, chlororespiration, and mitochondrial complex I and III assembly. It has been linked to numerous agronomic traits including grain yield, seed weight, grain size, plant height, anthesis time, heterosis, cold and drought tolerance, water use efficiency, net photosynthetic rate, chlorophyll content, root length, and protein content. Additional associations include cytoplasmic male sterility, shrunken endosperm, ear aspect, leaf curling, and parasitic weed response. The gene is also connected to plastoquinone redox state, tocopherol and vitamin K1 production, and oxidative stress tolerance. Studies of related genes in other species link the family to vitamin K1 biosynthesis, bolting time, and high light stress response.
