BRADI_5G23640V3 — Brachypodium distachyon

Summary

BdAXR6 (BRADI_5G23640V3) on chromosome 5 of Brachypodium distachyon encodes a cullin family protein and is annotated with ubiquitin ligase complex scaffold activity, NEDD8 transferase activity, ubiquitin-like protein transferase activity, and auxin receptor activity. The gene is associated with diverse biological processes including regulation of ethylene biosynthesis, protein neddylation, post-embryonic root development, gibberellic acid signalling, and responses to organophosphorus compounds and potassium ions. It has been linked to traits such as seed shattering, fruit ripening, photoperiod sensitivity, bacterial blight disease resistance, and responses to Cercospora leaf spot, rice narrow brown leaf spot, and wheat common root rot. The protein localises to CRL, CSN, and nucleotide-excision repair complexes. Studies of related cullin genes in other species connect the family to grain morphology, drought stress, UV-B tolerance, fertility, and disease resistance.
