LOX — Lactuca sativa

Summary

LsLOX, a lipoxygenase gene on lettuce chromosome 4, encodes a protein with linoleate 9S- and 13S-lipoxygenase activities, as well as phytoene dehydrogenase and peroxidase activities, and belongs to the plant lipoxygenase family. The gene is associated with oxylipin and jasmonic acid biosynthesis, green leaf volatile production, and responses to herbivores, insects, high light, and ozone. It has been linked to anther development, photoperiodic flowering, and seed yield traits. The encoded protein localises to chloroplast thylakoids, the apoplast, and stress granules. Related genes in other species connect the family to jasmonate-mediated defense against herbivory and necrotrophic pathogens, and to salt stress response.
