Oryza sativa | blast fungus infection induces the enzyme and phytoalexin sakuranetin production in rice, overview | up |
General Information | Comment | Organism |
---|---|---|
metabolism | the enzyme catalyzes the last step in sakuranetin biosynthesis, induced expression of a phytoalexin biosynthesis gene OsNOMT for naringenin 7-O-methyltransferase is found before accumulation of sakuranetin in both cultivars | Oryza sativa |
physiological function | the key enzyme produces the rice flavonoid phytoalexin sakuranetin for resistance against blast fungus infection. The concentration of sakuranetin accumulated in infected regions in the resistant rice line is effective enough to restrict the fungus, while that in susceptible rice is too low for it. Blast fungus converts sakuranetin to less toxic compounds | Oryza sativa |
