LOX — Cucumis melo

Summary

MELO3C014632.2 (CmLOX) on melon chromosome 6 encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase, phytoene dehydrogenase, peroxidase, and salicylic acid-binding activities. The gene 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. It is linked to anther development and dehiscence, filament development, abscission, photoperiodic flowering, and cell redox homeostasis. The protein localizes to chloroplast thylakoids, stromules, the apoplast, stress granules, and P bodies. Associations with seed yield, photosynthetic rate, root thickness, low temperature stress, and photoperiod-sensitive flowering time have been noted. Studies of related genes in other species connect the family to defense against herbivory, wound response, jasmonate signaling, and resistance to fungal pathogens and potyviruses.
