D61 — Zea mays

Summary

ZmD61 (BRI1, D61) on maize chromosome 3 encodes a leucine-rich repeat receptor-like kinase with a serine/threonine kinase domain and a BRI1 island domain. It is annotated with transmembrane receptor protein tyrosine kinase activity, protein kinase inhibitor activity, and signaling receptor binding. The gene is associated with brassinosteroid signaling, including negative regulation of brassinosteroid biosynthetic process and activation of brassinosteroid-mediated signalling. ZmD61 is linked to numerous agronomic traits: dwarfism, grain weight and width, shoot and root growth, leaf and inflorescence morphology, drought sensitivity, salt stress tolerance, and responses to temperature stress, aphids, and aluminum. It is also associated with root system development, phloem development, anther wall tapetum differentiation, and male sterility. Related genes in other species link the family to grain yield, plant architecture, and pathogen-associated molecular pattern-triggered immunity.
