CC -!- FUNCTION: Converts stearoyl-ACP to oleoyl-ACP by introduction of a cis
CC double bond between carbons 9 and 10 of the acyl chain. Required for
CC the repression of the salicylic acid (SA) signaling pathway.
CC {ECO:0000269|PubMed:19522564}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 H(+) + O2 + octadecanoyl-[ACP] + 2 reduced [2Fe-2S]-
CC [ferredoxin] = (9Z)-octadecenoyl-[ACP] + 2 H2O + 2 oxidized [2Fe-2S]-
CC [ferredoxin]; Xref=Rhea:RHEA:11776, Rhea:RHEA-COMP:9656, Rhea:RHEA-

CC ChEBI:CHEBI:78783; EC=1.14.19.2;
CC Evidence={ECO:0000250|UniProtKB:P22337};
CC -!- COFACTOR:
CC Name=Fe(2+); Xref=ChEBI:CHEBI:29033;
CC Evidence={ECO:0000250|UniProtKB:P22337};
CC Note=Binds 2 Fe(2+) ions per subunit. {ECO:0000250|UniProtKB:P22337};
CC -!- PATHWAY: Lipid metabolism; fatty acid metabolism.
CC -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P22337}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000305}.
CC -!- DISRUPTION PHENOTYPE: Increased level of stearate (18:0) and reduced
CC level of oleic acid (18:1) in leaves. Spontaneous lesion formation in
CC leaf blades, retarded growth, slight increase in endogenous free
CC salicylic acid (SA) levels and SA/benzothiadiazole (BTH)-specific
CC inducible genes. Enhanced resistance to the blast fungus Magnaporthe
CC grisea and leaf-blight bacteria Xanthomonas oryzae pv. oryzae.
CC {ECO:0000269|PubMed:19522564}.
CC -!- SIMILARITY: Belongs to the fatty acid desaturase type 2 family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAF07129.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
