ACO — Solanum lycopersicum

Summary

SOLYC07G026650.3, designated ACO (synonyms ACO5, ACO1, SlACO1) on tomato chromosome 7, encodes a protein with ACC oxidase activity, 2-oxoglutarate dioxygenase activity, metal and vitamin C binding, and a DIOX_N domain. In tomato, ACO1 is associated with carotenoid accumulation, bacterial wilt resistance, and cold tolerance. The gene is associated with ethene metabolism, cytokinin breakdown, and responses to ether, nitric oxide, and fatty acids, with cytoplasmic localisation. Associations include fruit ripening, lycopene, flavonoid, sucrose, starch, and chlorophyll content, fruit color and shape, plant height, root number and hair length, water use efficiency, ethylene sensitivity, germination rate, stomatal resistance, and responses to low temperature, oxidative stress, and drought. It is also linked to wound response, senescence, ethylene production and biosynthesis, salt stress tolerance, flooding tolerance, nematode resistance, gravitropic response, fruit shelf life, and firmness. Studies of related genes in other species link the family to disease resistance, lateral root development, iron acquisition, and female flower development.
