LOX — Cucumis melo

Summary

MELO3C014631.2 (symbol LOX, preferred name CmLOX) on melon chromosome 6 encodes a lipoxygenase, an oxidoreductase with linoleate 13S-lipoxygenase and peroxidase activities. The gene is associated with the lipoxygenase pathway, lipid oxidation, oxylipin and jasmonic acid biosynthesis, and green leaf volatile production. It has been linked to responses to herbivores, insects, high light intensity, and ozone, as well as anther development, dehiscence, filament development, abscission, and photoperiodic flowering. Associations with traits include photoperiod-sensitive flowering time, seed yield, photosynthetic rate, and low temperature stress response. The encoded protein localises to chloroplast thylakoids, stromules, stress granules, and the apoplast. Studies of related genes in other species link the lipoxygenase family to oxylipin biosynthesis, green leaf volatile production, and resistance to herbivores, fungal pathogens, and potyviruses.
