General annotation (Comments)

Function

13S-lipoxygenase that can use linolenic acid as substrates. Plant lipoxygenase may be involved in a number of diverse aspects of plant physiology including growth and development, pest resistance, and senescence or responses to wounding. It 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.6 Ref.25

Catalytic activity

Linoleate + O2 = (9Z,11E)-(13S)-13-hydroperoxyoctadeca-9,11-dienoate.

Cofactor

Binds 1 iron ion per subunit. Iron is tightly bound By similarity.

Pathway

Lipid metabolism; oxylipin biosynthesis.

Subunit structure

Interacts with EIF4E2. Ref.8

Subcellular location

Plastidchloroplast. Cytoplasm. Note: The unprocessed form is cytoplasmic whereas the cleaved form is chloroplastic. Ref.6 Ref.8 Ref.12 Ref.13 Ref.14 Ref.16 Ref.18 Ref.24

Tissue specificity

In leaves and inflorescences but not abundant in seeds, roots and stems. Ref.21

Developmental stage

Expression is sharply reduced in leaves during leaf senescence. Ref.11

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. Pseudomonas viridiflava and P. syringae pv. tomato). Repressed by WRKY62. Ref.7 Ref.9 Ref.10 Ref.15 Ref.17 Ref.19 Ref.20 Ref.23

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.
