ACC4 — Cucumis sativus

Summary

CsACC4 (ACC4, also known as ACS11) on cucumber chromosome 4 encodes a 1-aminocyclopropane-1-carboxylate synthase, a pyridoxal phosphate-dependent enzyme. The gene is associated with unisexual flower development and sex differentiation, as well as negative regulation of ethylene biosynthesis, carpel development, and response to organophosphorus and potassium ions. It is linked to fruit ripening, yield, leaf growth, root morphology traits including lateral root number and root hair length, photosynthetic rate, flowering time, disease tolerance, and responses to low temperature and bacterial pathogens. Related genes in other species connect the family to iron acquisition, wounding response, lateral root initiation, female flower differentiation, and sex determination.
