LOX — Lactuca sativa

Summary

LsLOX, encoded by the garden lettuce gene LSAT_V11C600317410 on chromosome 6, is a lipoxygenase enzyme with linoleate 13S-lipoxygenase and oxidoreductase activities. It is associated with lipid oxidation, oxylipin and jasmonic acid anabolism, and green leaf volatile biosynthetic process. The gene has been linked to responses to herbivore, insect, high light intensity, and ozone, as well as to anther development, anther dehiscence, and photoperiodism, flowering. Associations with nitrate content, nitrate transport, seed yield, photosynthetic rate, root thickness, and low temperature stress response have been noted. The encoded protein localises to chloroplast thylakoid, stromule, and apoplast. Studies of related genes in other species connect the family to wound response, jasmonate accumulation, drought resistance, and defense against herbivory.
