LITERATURE
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
metabolism
Q8L6H4
the enzyme is involved in the biosynthesis of jasmonic acid and related compounds
physiological function
Q8L6H4
the rice allene oxide cyclase functions in defence against blast fungus Magnaporthe oryzae through the pathway of jasmonate production
malfunction
-
12-oxophytodienoic acid-deficient rice allene oxide cyclase mutants show an increased tolerance to salt stress
physiological function
-
the enzyme can regulate the synthesis of rice phenolic acids and thus allelopathic inhibition on barnyardgrass
