ARRE — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0307740 (HvARRE) on barley chromosome 3H encodes a RING-type zinc finger protein with ubiquitin ligase activity and 5'-3' RNA polymerase activity. The gene is associated with syngamy, downregulation of abscisic acid-mediated signaling, ubiquitin-dependent proteolysis, cell division, root development, response to light stimulus, and defense response. Its product localizes to plastid and thylakoid membranes, mitochondria, the plasmalemma, and the nucleus. HvARRE is linked to photosynthetic rate. Studies of related genes in other species connect the family to cuticular wax biosynthesis, stomatal closure, fertility, pathogen response, seed germination, ABA sensitivity, and root elongation, while sequence similarity links the family to shoot and root dry weight, wheat stripe rust disease response, and stomatal complex closure time.
