ACS1 — Solanum lycopersicum

Summary

SlACS1 (SOLYC05G050010.3) on tomato chromosome 5 encodes a 1-aminocyclopropane-1-carboxylate synthase and also possesses transaminase activity, pyridoxal phosphate binding, protein kinase binding, phosphatase activity, and calcium ion binding. The gene is associated with fruit ripening, ACC accumulation, and ethylene production and sensitivity. It is linked to fruit color, firmness, shape, size, lycopene and carotenoid content, as well as vegetative vigor, leaf growth, shoot branching, and root development. SlACS1 is associated with responses to waterlogging, hypoxia, salt, cadmium, iron and nitrogen deficiency, wounding, and pathogens including Verticillium wilt, Pseudomonas syringae, and nematodes. Additional associations include pistil and flower development, seed yield, germination rate, starch and sucrose content, and strigolactone and polyamine metabolism.
