LOX — Cucumis melo

Summary

MELO3C014637.2 (CmLOX) on melon chromosome 6 encodes a lipoxygenase enzyme with linoleate 9S- and 13S-lipoxygenase activity, phytoene dehydrogenase activity, peroxidase activity, and salicylic acid binding. It is associated with the lipoxygenase pathway, lipid oxidation, oxylipin and jasmonic acid biosynthesis, green leaf volatile production, and responses to herbivores, insects, high light, and ozone. The gene is linked to anther development and dehiscence, filament development, abscission, photoperiodic flowering, and cell redox homeostasis. Associations with seed yield, photosynthetic rate, root thickness, and low temperature stress response have been noted. The protein localizes to chloroplast thylakoids, stromules, the apoplast, stress granules, and P bodies. Related genes in other species connect the family to jasmonate signaling, defense against herbivory and pathogens, and stress tolerance.
