LOX — Cucumis melo

Summary

MELO3C014628.2 (CmLOX) on melon chromosome 6 encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase and oxidoreductase activities, and is also annotated for phytoene dehydrogenase, peroxidase, and RNA cap binding functions. 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, filament development, abscission, photoperiodic flowering, and cell redox homeostasis. The protein localizes to chloroplast thylakoids, stromules, stress granules, and the apoplast. Associations include photoperiod-sensitive flowering time, seed yield, photosynthetic rate, low temperature stress response, root thickness, wound response, jasmonic acid and abscisic acid biosynthesis, drought resistance, herbivore resistance, cadmium and heat stress tolerance, and nitrogen use efficiency. Studies of related genes in other species connect the family to green leaf volatile production, thrips resistance, and resistance to fungal pathogens and potyviruses.
