MUB1 — Zea mays

Summary

ZM00001EB369510, designated ZmMUB1 on maize chromosome 8, encodes a ubiquitin fusion protein that is also a structural constituent of the ribosome (eS31 family) and is associated with histone acetyltransferase activity, double-stranded methylated DNA binding, and ubiquitin-protein transferase activity. The gene is associated with diverse biological processes including cell cycle process, pollen adhesion, response to chemical, and viral interactions. It localizes to the cytosolic small ribosomal subunit, ribosome, cytosol, and plasmodesmata. ZmMUB1 is linked to numerous agronomic traits such as plant growth habit, flour yield, grain number per spikelet, cob weight, seed length, leaf stomatal conductance, stay green trait, rubisco content, and acid soil tolerance. Related genes in other species are linked to heat and temperature stress tolerance, spike density, grain texture, and grain protein content.
