HOT1 — Zea mays

Summary

ZmHOT1 (ZM00001EB293780) on maize chromosome 6 encodes a protein with ATP hydrolase activity, ATP binding, protein binding, and protein phosphorylated amino acid binding, and is annotated as a protein folding chaperone. The gene is associated with heat tolerance, thermotolerance, long-term acquired thermotolerance, heat stress response, seed thermotolerance, and heat shock tolerance, as well as excess-light stress response and microgravity response. It is linked to grain size, grain weight, grain yield, drought tolerance, salt tolerance, crown root number, root number, nitrate uptake, leaf composition, heterosis, seedling growth, germination rate, organ identity, flowering time, root growth, fruit production, cell proliferation, leaf development, and nitrate assimilation. The product localizes to the chloroplast envelope, chloroplast stroma, mitochondria, nucleus, cytosol, Golgi complex, and plant-type vacuole, and is associated with hormone metabolism, cytokinin metabolism, brassinosteroid anabolism, protein refolding, and chloroplast stroma protein import.
