I57 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.1HG0040000 (HvI57) on barley chromosome 1H encodes a thiolase family protein with acetyl-CoA C-acetyltransferase (EC 2.3.1.16) and 3-ketothiolase activity. In barley, the gene is associated with fatty acid beta-oxidation, jasmonic acid anabolism, green leaf volatile biosynthetic process, citrate secretion, glyoxysome organization, phenylacetate breakdown, and upregulation of abscisic acid mediated signaling. It is linked to acid soil tolerance, aluminum tolerance, manganese concentration, leaf chlorosis, photosynthetic rate, and grain yield. The product localizes to multiple compartments including plastids, mitochondria, the ER, and vacuoles. Studies of related genes in other species connect the family to potassium transport, stomatal regulation, salt tolerance, seed yield, root length, lipid mobilization, and postgerminative growth.
