ARRE — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0747330 (HvARRE) on barley chromosome 7H encodes a RING-type zinc-finger protein with ubiquitin ligase activity and 5'-3' RNA polymerase activity. The gene is associated with seed trichome elongation, syngamy, downregulation of abscisic acid-mediated signaling, protein transport, ubiquitin-dependent proteolysis, cell division, root development, response to light stimulus, and defense response. It is linked to photosynthetic rate. The encoded protein localizes to plastid and thylakoid membranes, the endomembrane system, and protein storage vacuole membranes. Studies of related genes in other species link the family to cuticular wax biosynthesis, stomatal closure, fertility, pathogen response, seed germination, ABA sensitivity, and root elongation.
