VH1 — Zea mays

Summary

ZmVH1 (also known as BRI1, ZmBRI1, BRL2, ZmBRL2, VH1) on maize chromosome 1 encodes a leucine-rich repeat receptor-like kinase (LRR-RLK) with a BRI1 island domain and a serine/threonine kinase domain. The gene is associated with a wide range of molecular functions including transaminase, methyltransferase, and xylanase activities, as well as processes such as regulation of anthocyanin metabolism, glyoxylate cycle, and xylan breakdown. ZmVH1 has been linked to numerous agronomically important traits including seed yield, drought sensitivity, leaf angle, photosynthetic ability, lignin biosynthesis, herbicide sensitivity, and mineral and ion transport. It is also connected to phenotypes such as abnormal leaf venation, altered epicuticular wax composition, reduced height, and impaired stomatal closure. Studies of related genes in other species link the family to cotyledon vein patterning and vascular development.
