AXR6 (HORVU.MOREX.R3.1HG0022070) — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0022070 (HvAXR6) on barley chromosome 1H encodes a cullin family protein with ubiquitin ligase complex scaffold activity, NEDD8 transferase activity, and auxin receptor activity. This gene is associated with grain morphology in barley and linked to diverse processes including regulation of ethylene biosynthesis, protein neddylation, response to organophosphorus, and regulation of root development, gibberellic acid signalling, and carbohydrate metabolism. It has been connected to traits such as Cercospora leaf spot response, bacterial blight disease resistance, photoperiod sensitivity, iron and sulfur content, and fruit ripening. Related genes in other species are linked to auxin resistance, UV-B tolerance, fertility, far-red light signalling, drought stress, biotic stress, and lesion mimic phenotypes.
