LOX — Lactuca sativa

Summary

LsLOX, encoded by gene LSAT_V11C700375200 on lettuce chromosome 7, is a lipoxygenase with linoleate 13S-lipoxygenase activity, peroxidase activity, and RNA cap binding. It is associated with jasmonic acid anabolism, green leaf volatile biosynthetic process, and responses to herbivore, insect, virus, ozone, and high light intensity. The gene is linked to anther development, photoperiodism, flowering, and filament development. Associations include seed yield trait, photosynthetic rate, nitrate content, root thickness, and low temperature stress response. Localization evidence connects the product to chloroplast thylakoid membrane, stromule, stress granule, and apoplast. Studies of related genes in other species link the family to oxylipin biosynthesis, defense against herbivory, and resistance to fungal pathogens and potyviruses.
