Component of the monoterpenoid pyrethrins biosynthesis; pyrethrins are widely used plant-derived pesticide (PubMed:30468448). Plant lipoxygenases may be involved in a number of diverse aspects of plant physiology including growth and development, pest resistance, and senescence or responses to wounding. Catalyzes the hydroperoxidation of lipids containing a cis,cis-1,4-pentadiene structure (By similarity). Mediates the peroxidation of linolenic acid leading to the production of 13-hydroperoxylinolenic acid (PubMed:23893337). (9Z,12Z,15Z)-octadecatrienoate + O2 = 13-hydroperoxy-(9Z,11E,15Z)-octadecatrienoate Binds 1 Fe cation per subunit. Lipid metabolism; oxylipin biosynthesis. Isoprenoid biosynthesis. Confined to glandular trichomes in flowers, and, at low levels, in leaves. In flowers, expressed in early developmental stages and fades out progressively in later stages. Belongs to the lipoxygenase family.
