ACO1 — Cucumis melo

Summary

MELO3C007942.2, designated CmACO1 on melon chromosome 9, encodes a protein with aconitase, intramolecular hydroxytransferase, and 3-isopropylmalate dehydratase activities, binding 4Fe-4S clusters, copper, ATP, and mRNA 5'-UTR. In melon, CmACO1 is associated with fruit shelf-life, sex determination, the TCA cycle, citrate and isocitrate metabolism, the glyoxylate cycle, methionine metabolism, fermentation, glucosinolate anabolism, regulation of salicylic acid signaling, negative regulation of leaf senescence, pollen maturation, and trichome morphogenesis. The protein localizes to mitochondria, chloroplast stroma, plastids, cytosol, plasmalemma, apoplast, cell wall, vacuole, and plasmodesmata. CmACO1 is also linked to fruit firmness, ethylene sensitivity, root morphology, lateral root development, waterlogging stress tolerance, ethylene production, plant growth, gravitropic response, salt tolerance, and abiotic stress response. Studies of related genes in other species connect the family to seed volume, submergence tolerance, lycopene and carotenoid content, fruit color and shape, root traits, starch and protein content, germination rate, chlorophyll content, and oxidative stress response.
