HORVU.MOREX.R3.2HG0205830 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0205830, designated HvAXR6 on barley chromosome 2H, encodes a cullin family protein with ubiquitin ligase complex scaffold activity, NEDD8 transferase activity, and auxin receptor activity. The gene is associated with grain morphology in barley and linked to diverse biological processes including regulation of ethylene biosynthesis, protein neddylation, response to organophosphorus, and regulation of root development and gibberellic acid signalling. It localises to the CRL complex, nucleotide-excision repair complex, and chromatin silencing complex. Associations with agronomically relevant traits include responses to Cercospora leaf spot, rice narrow brown leaf spot, wheat common root rot, bacterial blight disease resistance, photoperiod sensitivity, and grain morphology. Related genes in other species link the family to auxin response, UV-B tolerance, fertility, fruit ripening, drought stress, lesion mimic, and disease resistance.
