BRADI_5G23645V3 — Brachypodium distachyon

Summary

BdAXR6 (BRADI_5G23645V3) on chromosome 5 of Brachypodium distachyon encodes a cullin-family protein with ubiquitin ligase complex scaffold activity, NEDD8 transferase activity, and auxin receptor activity. The gene is associated with regulation of protein ubiquitination, protein neddylation, and SCF-dependent proteasomal protein breakdown. It has been linked to diverse biological processes including response to organophosphorus, regulation of ethylene biosynthesis, gibberellic acid signalling, root development, stem cell renewal, and carbohydrate metabolism. Associations with agronomic traits include seed shattering, grain morphology, tiller number, biomass yield, grain length, anthesis time, and responses to multiple diseases such as rice blast, bacterial blight, Fusarium head blight, and Cercospora leaf spot. The gene also connects to stress responses including drought, UV-B, oxidative stress, and nitrate sensitivity.
