ACS1 — Cucumis sativus

Summary

CsACS1 (CSA_6G006800) on cucumber chromosome 6 encodes a 1-aminocyclopropane-1-carboxylate synthase, an enzyme with transaminase and pyridoxal phosphate binding activities that catalyzes the committed step in ethylene biosynthesis. The gene is associated with female sex determination, flower formation, pigmentation, cell wall thickening, dehiscence, and alternative respiration. It has been linked to numerous agronomically important traits including fruit length, fruit shape and size, seed yield, vegetative vigor, leaf growth, shoot branching, photosynthetic and transpiration rates, germination rate, and responses to abiotic stresses such as waterlogging, salt, cadmium, and nitrogen deficiency. Additional associations include ethylene sensitivity, auxin sensitivity, brassinosteroid sensitivity, stomatal resistance, root meristem development, and resistance to Verticillium wilt, powdery mildew, and necrotrophic pathogens.
