LOX — Cucumis melo

Summary

MELO3C014634.2 (CmLOX) on melon chromosome 6 encodes a lipoxygenase, possessing linoleate 13S-lipoxygenase and oxidoreductase activities, along with phytoene dehydrogenase, peroxidase, and salicylic acid binding functions. It is associated with the lipoxygenase pathway, lipid oxidation, oxylipin and jasmonic acid biosynthesis, and green leaf volatile production. The gene is linked to responses to herbivores, insects, high light intensity, and ozone, as well as abscission, anther development and dehiscence, filament development, and photoperiodic flowering. Associations with seed yield, photosynthetic rate, root thickness, and low temperature stress response have been noted. The encoded protein localizes to chloroplast thylakoids, stromules, stress granules, and the apoplast. Studies of related lipoxygenases in other species connect the family to wound response, herbivore resistance, drought resistance, and jasmonate accumulation.
