AXR6 — Brachypodium distachyon

Summary

BdAXR6 (BRADI_3G59330V3) on chromosome 3 of Brachypodium distachyon encodes a cullin family protein with ubiquitin ligase complex scaffold activity, NEDD8 transferase activity, auxin receptor activity, and auxin binding. This gene is associated with regulation of ethylene biosynthesis, protein neddylation, response to organophosphorus, regulation of post-embryonic root development, and positive regulation of organ growth. It has been linked to numerous traits including seed shattering, fruit ripening, bacterial blight disease resistance, Cercospora leaf spot response, rice leaf sheath blight disease, photoperiod sensitivity, branch angle, iron and molybdenum content, and seedling cotyledon morphology. Studies of related genes in other species connect the cullin family to grain morphology, tiller number, grain yield, biomass, drought stress, disease resistance, and UV-B tolerance.
