LOX — Cucumis melo

Summary

MELO3C014635.2 (CmLOX, LOX) on melon chromosome 6 encodes a lipoxygenase, an iron-binding oxidoreductase with linoleate 9S- and 13S-lipoxygenase activity, and is also annotated for phytoene dehydrogenase, peroxidase, and RNA cap binding activities. The gene is associated with the lipoxygenase pathway, lipid oxidation, oxylipin and jasmonic acid biosynthesis, green leaf volatile production, and responses to herbivores, insects, ozone, high light, and wounding. It is linked to abscission, anther dehiscence, filament development, stomatal closure, photoperiodic flowering, and traits including seed yield, photosynthetic rate, root thickness, and low temperature stress response. The protein localises to chloroplast thylakoids, stromules, the apoplast, P-bodies, and stress granules. Studies of related genes in other species connect the family to herbivore resistance, jasmonate signalling, and stress tolerance.
