ACS — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0329220 (HvACS) on barley chromosome 3H encodes a member of the AMP-binding protein family with propionate-CoA ligase, acetate-CoA ligase, benzoate-CoA ligase, and 4-coumarate-CoA ligase activities. The gene is associated with butyrate and acetate metabolism, branched-chain amino acid breakdown, fatty-acyl-CoA anabolism, cinnamic acid metabolism, phytoalexin biosynthesis, ethylene anabolism, green leaf volatile biosynthesis, and wax anabolism. It has been linked to stem rust, photosynthetic rate, grain yield, plant height, root elongation, and seedling development. The encoded protein localizes to mitochondria and cytosol. Studies of related genes in other species connect the family to benzoyloxyglucosinolate biosynthesis, stomatal conductance, leaf photosynthesis, drought resistance, and defense against Magnaporthe oryzae.
