ACO1 — Cucumis melo

Summary

MELO3C004619.2 (symbol ACO1, also known as CmACO1) on melon chromosome 6 encodes an ACC oxidase (EC 1.14.17.4), a 2-oxoglutarate dioxygenase with ACC oxidase and vitamin C binding activities. The gene is associated with ethylene biosynthesis, fruit development and abscission, sex determination, shoot regeneration, fermentation, exocytosis, coumarin anabolism, and cellular responses to nitric oxide, fatty acids, and potassium ion starvation. It is linked to traits including respiration rate, ethylene sensitivity, fruit shelf life, and tolerance to salt, flooding, cold, and heat stress, as well as wound response, senescence, gravitropic response, and resistance to necrotrophic infection. The protein localises to the cytoplasm. Studies of related genes in other species connect the family to fruit ripening, carotenoid accumulation, disease resistance, lateral root development, iron acquisition, and female flower development.
