ACO1 — Cucumis melo

Summary

MELO3C032251.2 (ACO1) on melon chromosome 7 encodes an aconitase family protein with aconitase, 3-isopropylmalate dehydratase and intramolecular hydroxytransferase activities, and binds 4Fe-4S clusters, copper, ATP, mRNA 5′-UTRs and poly(U). In melon, ACO1 is associated with fruit shelf-life, ethylene anabolism, sex determination, the TCA cycle, citrate and isocitrate metabolism, the SAM cycle, methionine metabolism, the glyoxylate cycle, fermentation, glucosinolate and indole glucosinolate anabolism, regulation of salicylic acid-mediated signalling, negative regulation of leaf senescence, trichome morphogenesis, downregulation of defense response, regulation of ROS metabolic process, and response to iron ion starvation. It is 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. The protein localises to mitochondria, cytosol, plastid, chloroplast stroma, plasmalemma, plant-type cell wall, plant-type vacuole, apoplast, plasmodesma and the PP2A complex.
