D61 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0285210 (symbol D61, also known as BRI1) on barley chromosome 3H encodes a leucine-rich repeat receptor-like kinase (LRR-RLK) with a BRI1 island domain and serine/threonine kinase activity. The gene is associated with negative regulation of brassinosteroid biosynthetic process, root system development, phloem development, anther wall tapetum cell differentiation, and negative gravitropism. It has been linked to fungal disease resistance in barley and to numerous agronomic traits including grain weight, grain width, biomass, leaf angle, shoot growth, dwarfism, and responses to salt, water, and temperature stress. Additional associations include plant male sterility, harvest index, and phototropism response. Related genes in other species are linked to defense response to pathogen, abscisic acid sensitivity, and endoplasmic reticulum-associated degradation.
