I57 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0219040 (HvI57) on barley chromosome 3H encodes a thiolase family protein with acetyl-CoA C-acetyltransferase (EC 2.3.1.9) and 3-ketothiolase activity. The gene is associated with fatty acid beta-oxidation, jasmonic acid anabolism, green leaf volatile biosynthetic process, glyoxysome organization, citrate secretion and transport, sterol metabolism, 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 plant-type vacuoles. Studies of related genes in other species connect the family to potassium channel activity, stomatal regulation, and salt tolerance, as well as seed yield, root length, fertility, and mevalonate biosynthesis.
