LOX — Lactuca sativa

Summary

LsLOX, encoded by gene LSAT_V11C600317370 on lettuce chromosome 6, is a lipoxygenase family protein with linoleate 13S-lipoxygenase activity, oxidoreductase activity, and phytoene dehydrogenase activity. It is associated with jasmonic acid and oxylipin biosynthesis, green leaf volatile production, and responses to herbivores, insects, ozone, and high light intensity. The gene has been linked to anther development, photoperiodic flowering, and filament development. Localisation evidence connects it to chloroplast thylakoids, stromules, stress granules, and the apoplast. Associations with nitrate content, seed yield, photosynthetic rate, root thickness, and low temperature stress response have been noted. Studies of related genes in other species link the family to jasmonate-mediated defense, resistance to herbivory and necrotrophic pathogens, leaf senescence, and green leaf volatile biosynthesis.
