EFE — Cucumis melo

Summary

MELO3C019735.2 (CmEFE, also known as CmACO4, CmEAT1) on melon chromosome 12 encodes an ACC oxidase (EC 1.14.17.4) with 2-oxoglutarate dioxygenase activity, a member of the IPNS-like Fe2OG oxygenase family. This gene is associated with ethylene biosynthesis and signaling, fruit ripening and development, cell wall disassembly, and responses to auxin, abscisic acid, and fungal elicitors. It is linked to sucrose and carotenoid anabolism, shoot regeneration, and hormone and coumarin biosynthesis. The encoded protein localizes to the cytosol, cytoplasm, extracellular region, and stress granules. Associations with ethylene sensitivity, disease resistance, adventitious root formation, nitrogen deficiency response, iron acquisition, and abiotic stress tolerance have been observed. Studies of related genes in other species link the family to female flowering, plant height, drought tolerance, and seedling growth.
