General annotation (Comments)
| Function | 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. Ref.7 Ref.26 |
| Catalytic activity | Linoleate + O2 = (9Z,11E,13S)-13-hydroperoxyoctadeca-9,11-dienoate. Alpha-linolenate + O2 = (9Z,11E,13S,15Z)-13-hydroperoxyoctadeca-9,11,15-trienoate. |
| Cofactor | Binds 1 iron ion per subunit. Iron is tightly bound By similarity. |
| Pathway | |
| Subunit structure | Interacts with EIF4E2. Ref.9 |
| Subcellular location | Plastid › chloroplast. Cytoplasm. Note: The unprocessed form is cytoplasmic whereas the cleaved form is chloroplastic. Ref.7 Ref.9 Ref.13 Ref.14 Ref.15 Ref.17 Ref.19 Ref.25 |
| Tissue specificity | In leaves and inflorescences but not abundant in seeds, roots and stems. Ref.22 |
| Developmental stage | Expression is sharply reduced in leaves during leaf senescence. Ref.12 |
| Induction | 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. Ref.8 Ref.10 Ref.11 Ref.16 Ref.18 Ref.20 Ref.21 Ref.24 |
| Sequence similarities | Belongs to the lipoxygenase family. Contains 1 lipoxygenase domain. Contains 1 PLAT domain. |
| Sequence caution | The sequence CAB72152.1 differs from that shown. Reason: Erroneous gene model prediction. |
