13S-lipoxygenase that can use linolenic acid as substrates. 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. Required for the wound-induced synthesis of jasmonic acid (JA) in leaves. (9Z,12Z)-octadecadienoate + O2 = (13S)-hydroperoxy-(9Z,11E)-octadecadienoate (9Z,12Z,15Z)-octadecatrienoate + O2 = (13S)-hydroperoxy-(9Z,11E,15Z)-octadecatrienoate Binds 1 Fe cation per subunit. Iron is tightly bound. Lipid metabolism; oxylipin biosynthesis. Interacts with EIF4E2. The unprocessed form is cytoplasmic whereas the cleaved form is chloroplastic. In leaves and inflorescences but not abundant in seeds, roots and stems. Expression is sharply reduced in leaves during leaf senescence. By methyl jasmonate (MeJA) and wounding, probably through nitric oxide-mediated (NO) induction. Slightly locally induced upon herbivors infestation such as aphids (Myzus persicae and Brevicoryne brassicae), or caterpillar (Spodoptera exigua). Induced by leaf-volatiles generated by herbivors-mediated wounding such as (E)-2-hexenal, (Z)-3-hexenal, (Z)-3-hexenol or allo-ocimene (2,6-dimethyl-2,4,6-octatriene). Increased levels by bacterial pathogens (e.g. P.viridiflava and P.syringae pv. tomato). Repressed by WRKY62. Belongs to the lipoxygenase family.
