D61 — Brachypodium distachyon

Summary

BdD61 (BRADI_2G48279V3) on Brachypodium distachyon chromosome 2 encodes a protein with leucine-rich repeat, BRI1 island, and serine/threonine kinase domains. The gene is associated with negative regulation of brassinosteroid biosynthetic process and activation of brassinosteroid-mediated signalling. It is linked to traits including leaf shattering, shoot growth angle, grain weight and width, biomass, panicle development, root growth, and responses to water stress, temperature stress, aluminum, aphids, and powdery mildew. Localization evidence connects the product to the plasma membrane, tonoplast, and endosomal compartments. Studies of related genes in other species link the family to brassinosteroid perception, plant architecture, grain yield, seed size, and stress tolerance including thermotolerance and fungal disease resistance.
