ACO — Phaseolus vulgaris

Summary

PHAVU_003G082300, designated PvACO, encodes a protein with ACC oxidase activity, 2-oxoglutarate dioxygenase activity, metal binding and vitamin C binding, placing it in the DIOX_N and IPNS-like Fe2OG oxygenase families. In French bean, PvACO is associated with ethylene biosynthesis, fruit ripening, leaf development, chlorophyll metabolism, coumarin anabolism, nitric oxide storage, and responses to fungi and fungal molecules. It localises to the cytosol, cytoplasm, stress granules and extracellular space. The gene has been connected to seed weight, seed size, cellulose and lignin content, respiration rate, ethylene sensitivity, drought tolerance, disease resistance and nitrogen deficiency response. Studies of related genes in other species link the family to germination rate, seedling growth, root length, stomatal opening, proline content, leaf necrosis, flower and seed coat colour, and salt tolerance.
