ARRE — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0687790 (HvARRE) on barley chromosome 7H encodes a RING-type zinc-finger domain-containing protein with ubiquitin ligase activity and 5'-3' RNA polymerase activity. The gene is associated with protein ubiquitination, ubiquitin-dependent proteolysis, cell division, root development, defense response, response to light stimulus, and downregulation of abscisic acid-mediated signaling. It is linked to syngamy, homeostasis, and photosynthetic rate. The encoded protein localizes to plastid and thylakoid membranes, the nucleus, mitochondria, and the plasmalemma. Studies of related genes in other species connect the family to cuticular wax biosynthesis, fertility, seed germination, ABA sensitivity, root elongation, and pathogen response, while sequence similarity links associate the family with stripe rust disease response, shoot and root dry weight, and stomatal closure.
