ACS1 — Lactuca sativa

Summary

LsACS1, located on chromosome 3 of garden lettuce (Lactuca sativa), encodes a protein with 1-aminocyclopropane-1-carboxylate synthase activity and transaminase activity, and binds pyridoxal phosphate. The gene is associated with a wide range of biological processes, including ethylene anabolism, cold acclimation, response to freezing, regulation of stomatal movement, root hair initiation, and phloem or xylem histogenesis. It has been linked to numerous agronomic traits such as leaf length, seed yield, photosynthetic rate, anthocyanin content, seed dormancy, leaf senescence, and responses to biotic and abiotic stresses including powdery mildew, waterlogging, and low temperature. The encoded protein is predicted to localize to the cytosol, plastid, mitochondria, plasmalemma, and plant-type cell wall.
