ACS — Pisum sativum

Summary

PsACS (PSAT3G091520) on garden pea chromosome 3LG5 encodes a protein with domains including Ac_CoA_lig, ACAS_N, and AMP-bd_C, and is a member of the AMP-binding superfamily. The enzyme exhibits acetate-CoA ligase activity, along with medium-chain fatty acid-CoA ligase, trans-feruloyl-CoA synthase, (E)-caffeate-CoA ligase, trans-cinnamate-CoA ligase, and 4-coumarate-CoA ligase activities. It is associated with abscission, seed development, nodulation, geotropism, cell growth, and responses to jasmonic acid and heat. The protein localizes to plastids, chloroplast stroma, cytosol, and membranes. Associations with proline content, salt tolerance (SALTTL), biomass heterosis, flowering time, and plant growth have been noted. Studies of related genes in other species link the family to drought tolerance, root length, stomatal opening, and vegetative vigor.
