ACS1 — Lactuca sativa

Summary

LsACS1 on chromosome 6 of garden lettuce encodes a 1-aminocyclopropane-1-carboxylate synthase and also exhibits transaminase, phosphatase, and protein kinase binding activities. The gene is associated with ethylene production and sensitivity, ACC accumulation, and a range of developmental and stress responses including root hair initiation, stomatal movement, cold acclimation, freezing tolerance, and responses to jasmonic acid, waterlogging, hypoxia, salt stress, cadmium, iron deficiency, nitrogen starvation, and phosphate starvation. It is linked to traits such as leaf length, vegetative vigor, seed yield, photosynthetic rate, anthocyanin content, leaf senescence, seed dormancy, shoot branching, root development, and resistance to powdery mildew, Verticillium wilt, and Pseudomonas syringae. The protein localizes to the cytosol, plastid, mitochondria, plasmalemma, plasmodesma, Golgi, vacuole, and cell wall.
