ACS — Cucumis melo

Summary

MELO3C014749.2 (symbol CmACS) on melon chromosome 7 encodes an acetate-CoA ligase (EC 6.2.1.1) with AMP-binding, CoA-ligase, medium-chain fatty-acid-CoA ligase, trans-cinnamate-CoA ligase, and 4-coumarate-CoA ligase activities. The gene is associated with sex determination, carpel and stamen development, fruit abscission, ethylene biosynthesis, and response to jasmonic acid. It has been linked to flower development, pollen tube attraction, biomass heterosis, acetate sensitivity, plant growth and flowering time. The encoded protein localises to the chloroplast stroma, plastid, membrane, cytosol and cytoplasm, and is associated with acetate metabolism, fatty-acyl-CoA anabolism, phenylpropanoid metabolism and secondary metabolism. Studies of related genes in other species link the ACS family to fruit ripening, aroma volatiles, lycopene accumulation, salt tolerance, cold stress response, and traits including harvest index, fruit size and shape, plant height, flowering time and drought tolerance.
