ACS — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0504670, designated HvACS on barley chromosome 5H, encodes an AMP-binding domain protein with acetate-CoA ligase, 4-coumarate-CoA ligase, and medium-chain fatty acid-CoA ligase activities (EC 6.2.1.12). The gene is associated with ethylene biosynthesis, phenylpropanoid metabolism, phytoalexin biosynthesis, green leaf volatile production, and fatty-acyl-CoA anabolism. It is linked to defense responses, responses to ethylene and other hormones, circadian rhythm, fruit development and ripening, and regeneration. The encoded protein localises to the peroxisome and cytosol. HvACS is also linked to stem rust. Related genes in other species connect the broader gene family to additional CoA-ligase activities (EC 6.2.1.17, 6.2.1.1).
