ACS — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.2HG0215760 (HvACS) on barley chromosome 2H encodes an AMP-binding domain protein with propionate-CoA ligase, acetate-CoA ligase, benzoate-CoA ligase, and 4-coumarate-CoA ligase activities. The gene is associated with mitochondrial and cytosolic localisation, and linked to butyrate and acetate metabolism, branched-chain amino acid breakdown, cinnamic acid metabolism, phytoalexin biosynthesis, wax anabolism, phenylpropanoid metabolism, green leaf volatile biosynthesis, ethylene anabolism, glucosinolate anabolism, circadian rhythm, and fruit development and ripening. Associations with stem rust, photosynthetic rate, plant height, grain yield, root elongation, and seedling development have been noted. Studies of related genes in other species connect the family to drought tolerance, stomatal conductance, leaf photosynthesis, and benzoyloxyglucosinolate accumulation.
