LOX — Cucumis melo

Summary

MELO3C000684.2 (CmLOX) on melon chromosome 6 encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase, peroxidase, and phytoene dehydrogenase activities, and is associated with salicylic acid and mRNA binding. The gene is linked to the lipoxygenase pathway, lipid oxidation, oxylipin and jasmonic acid biosynthesis, green leaf volatile production, and responses to herbivores, insects, ozone, and high light intensity. It has been connected to photoperiod-sensitive flowering, seed yield, photosynthetic rate, low temperature stress, root thickness, and embryo development. Associations also include wound response, jasmonic acid and abscisic acid biosynthesis, cadmium and heat stress tolerance, drought resistance, herbivore defense, nitrogen use efficiency, and virus resistance. The protein localizes to chloroplast thylakoids, stromules, P bodies, 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 thrips, fungal pathogens, and herbivory.
