I57 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0100130 (HvI57) on barley chromosome 2H encodes a thiolase N-terminal domain-containing protein with acetyl-CoA C-acetyltransferase and 3-ketothiolase activity. This gene is associated with fatty acid beta-oxidation, glyoxysome organization, jasmonic acid anabolism, green leaf volatile biosynthetic process, citrate secretion, citrate transport, sterol metabolism, detoxification, and upregulation of abscisic acid mediated signaling. It has been linked to acid soil tolerance, aluminum tolerance, manganese concentration, leaf chlorosis, photosynthetic rate, and grain yield. Additional associations include pollen germination, embryo development ending in seed dormancy, and stomatal regulation. The gene product localizes to the cytoplasm, plastid, mitochondria, ER, nucleolus, and plasmalemma. Studies of related genes in other species connect the family to potassium transport, salt tolerance, seed yield, root length, lipid mobilization, and postgerminative growth.
