LOX — Cucumis sativus

Summary

CsLOX (CSA_7G449420) on cucumber chromosome 7 encodes a lipoxygenase enzyme with linoleate 9S- and 13S-lipoxygenase activities, iron binding, and additional annotated functions including phytoene dehydrogenase, peroxidase, and salicylic acid binding activities. The protein is associated with the lipoxygenase pathway, jasmonic acid and oxylipin biosynthesis, lipid oxidation, carotenoid and chlorophyll anabolism, and responses to herbivory and high light intensity. It localizes to chloroplast thylakoids, stromules, stress granules, and the apoplast. The gene is linked to seed yield, plant height, stem diameter, leaf number, photosynthetic rate, chlorophyll and carotenoid content, stomatal resistance, photoperiod-sensitive flowering, and low temperature stress response. Related genes in other species connect the family to jasmonate-mediated defense, herbivore resistance, wound response, and abiotic stress tolerance.
