-
deletion mutants of AOC1 and AOC2 show reduced fertility, aberrant sporophyte morphology and interrupted sporogenesis
malfunction
Q8L6H4
two photomorphogenic mutants of rice, coleoptile photomorphogenesis 2 (cpm2) and hebiba, are defective in the gene encoding allene oxide cyclase, phenotypes, overview. Both mutants are more susceptible than wild-type to an incompatible strain of Magnaporthe oryzae in such a way that hyphal growth is enhanced in mutant tissues. Blast-induced accumulation of phytoalexins, especially that of the flavonoid sakuranetin, is severely impaired in cpm2 and hebiba
malfunction
-
12-oxophytodienoic acid-deficient rice allene oxide cyclase mutants show an increased tolerance to salt stress

-
loss-of-function of isoform AOC3 renders plants more susceptible to nematode Meloidogyne javanica infection
allene oxide cyclase is a key enzyme in jasmonates biosynthetic pathway
metabolism
allene oxide cyclase is the most important enzyme for the jasmonic acid biosynthesis
metabolism
-
isoforms AOC1 and AOC2 are key enzymes in the formation of jasmonic acid and its precursor (9S,13S)-12-oxo-phytodienoic acid
metabolism
-
key enzyme of the jasmonate biosynthetic pathway catalysing the formation of (9S,13S)-12-oxo-phytodienoic acid and establishes the stereochemical configuration of naturally occurring jasmonate. Spontaneous hydrolysis of the allene oxide also yields (9S,13S)-12-oxo-phytodienoic acid, although in its racemic form
metabolism
Q8L6H4
the enzyme is involved in the biosynthesis of jasmonic acid and related compounds
metabolism
the first specific step in the biosynthesis of the cyclopentanone class of oxylipins is catalyzed by allene oxide cyclase that forms cis(+)-12-oxo-phytodienoic acid. After reduction of the cyclopentenone by cis(+)-12-oxo-phytodienoic acid reductase isoform 3, the octanoic or hexanoic side chain is shortened by beta-oxidation cycles, pathway overview
Q8L6H4
the rice allene oxide cyclase functions in defence against blast fungus Magnaporthe oryzae through the pathway of jasmonate production
physiological function
-
enzyme overexpression leads to an enhanced level of tolerance to salinity and increased jasmonic acid accumulation in wounded leaves
physiological function
-
the enzyme can regulate the synthesis of rice phenolic acids and thus allelopathic inhibition on barnyardgrass
physiological function
-
the enzyme is a signaling molecule regulating growth and the response to wounding in the liverwort Marchantia polymorpha
physiological function
-
the enzyme plays an important role in increasing the expression of transcription factors (MYB2 and ONAC045) and functional genes (DREB1F and LEA3) in transgenic rice under salt stress as well as improve stress tolerance through the accumulation of compatible solutes (proline and soluble sugar)
