HORVU.MOREX.R3.3HG0225290 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0225290 (HvAXR6) on barley chromosome 3H encodes a cullin family protein with ubiquitin ligase complex scaffold activity, NEDD8 transferase activity, and auxin receptor activity. In barley, the gene is associated with grain morphology. It is linked to diverse biological processes including regulation of ethylene biosynthesis, protein neddylation, response to organophosphorus, regulation of root development, and gibberellic acid signalling. The encoded protein localises to the CRL complex, nucleotide-excision repair complex, and chromatin silencing complex. Studies of related genes in other species link the family to auxin resistance, fertility, leaf development, UV-B tolerance, drought stress, biotic stress responses, and grain traits.
