ACO1 — Cucumis sativus

Summary

CSA_2G000520 (symbol ACO1, also known as ACO2) on cucumber chromosome 2 encodes an ACC oxidase (EC 1.14.17.4) with ACC oxidase and 2-oxoglutarate dioxygenase activities, vitamin C and metal binding, and belongs to the Fe2OG oxygenase superfamily. The gene is associated with ethylene biosynthesis, fruit ripening, flower development, and sex differentiation, and has been linked to female flower development in cucumber. It is also associated with cellular responses to nitric oxide and fatty acids, alternative respiration, adventitious root development, induced systemic resistance, and responses to fungal molecules. Associations include female flowering, respiration rate, floral organ identity, ethylene sensitivity, wound response, senescence, salt stress tolerance, flooding tolerance, heat and cold stress responses, fruit shelf life, and gravitropic response. Studies of related genes in other species link the family to ethylene production, disease resistance, iron acquisition, and fruit ripening traits.
