LOX — Cucumis sativus

Summary

CsLOX (CSA_5G590080) on cucumber chromosome 5 encodes a protein with lipoxygenase and PLAT/LH2 domains and with linoleate 9S- and 13S-lipoxygenase activities, as well as phytoene dehydrogenase, peroxidase, and RNA cap-binding activities. The protein localizes to chloroplast thylakoids, stromules, and stress granules. CsLOX is associated with the lipoxygenase pathway, oxylipin and jasmonic acid biosynthesis, carotenoid and chlorophyll metabolism, and responses to herbivory and high light intensity. It has been linked to traits including linoleic acid and carotenoid content, photosynthetic rate, chlorophyll content, seed yield, plant height, stem diameter, leaf number, root thickness, and photoperiod-sensitive flowering. Associations with wound response, jasmonate production, drought resistance, cadmium and heat stress tolerance, herbivore resistance, and root-knot nematode susceptibility have also been reported.
