LOX — Cucumis melo

Summary

MELO3C011885.2 (CmLOX) on melon chromosome 11 encodes a lipoxygenase, an enzyme with linoleate 13S-lipoxygenase and oxidoreductase activities. 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 photoperiodism and flowering. Associations include photoperiod-sensitive flowering time, seed yield, photosynthetic rate, low temperature stress response, root thickness, wound response, jasmonic acid accumulation, drought resistance, herbivore resistance, and cadmium stress tolerance. The protein localises to chloroplast thylakoids, stromules, stress granules, and the apoplast. Studies of related genes in other species connect the lipoxygenase family to oxylipin biosynthesis, green leaf volatile production, and resistance to herbivores and fungal pathogens.
