The development of LOX null lines has provided an ideal genetic material to determine possible physiological roles for seed LOX. Genetic elimination of seed LOX was followed by a corresponding decrease in the levels of protease inhibitors in soybean seeds. Participation of LOX in the biosynthetic pathway leading to jasmonates, which activate protease inhibitor genes, has been demonstrated in leaves of several plant species. It is conceivable that LOX has a similar role in the developing seed.pdfengElsevier, ParisLipoxygenasesSoybeanProtease inhibitorsArtigo
