metabolism
physiological function
additional information
naringenin 7-O-methyltransferase is a key enzyme in biosynthesis of flavonoid phytoalexin sakuranetin in rice
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
metabolism
the enzyme catalyzes the last step in the biosynthesis of the bioactive flavonoid sakuranetin, biosynthetic pathway starting with glucose, overview
metabolism
the key enzyme produces the rice flavonoid phytoalexin sakuranetin, the enzyme catalyzes the last step in sakuranetin biosynthesis, rice phytoalxin and diterpenoid metabolism, overview
physiological function
-
the enzyme catalyzes the terminal step in the biosynthesis of the flavanone sakuranetin, the major phytoalexin produced by Oryza sativa that is involved in defense related response
physiological function
-
the enzyme is involved in the biosynthesis of the flavanone phytoalexin sakuranetin. Plants possess inducible defence mechanisms against pathogen attack that include the production of phytoalexins. The product of the reaction, sakuranetin is a major rice phytoalexin accumulating both in ultraviolet irradiated and blast infected as well as in copper chloride or jasmonic acid, treated rice leaves
physiological function
naringenin 7-O-methyltransferase is a key enzyme in biosynthesis of major flavonoid phytoalexin sakuranetin in rice, sakuranetin is a useful compound as a plant antibiotic and a potential pharmaceutical agent
physiological function
-
Sakuranetin is a the major flavonoid phytoalexin in rice, and is useful as plant antibiotic and pharmaceutical agent
physiological function
te enzyme is required for biosynthesis of sakuranetin, a phytoalexin in rice, enzyme upregulation might lead to increased plant pathogen resistance
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
physiological function
-
leaves of rice cultivar Nipponbare predominantly accumulate the phytoalexin sakuranetin after jasmonic acid induction. The Kasalath cultivar accumulates only low amounts of sakuranetin. Both NOMT expression and NOMT enzymatic activity are lower in Kasalath than in Nipponbare. A proline to threonine substitution in Kasalath relative to Nipponbare NOMT is the main cause of the lower enzymatic activity. The relative amounts of naringenin and sakuranetin may provide protection against specific pathogen profiles in different rice-growing environments. Naringenin is more effective against bacterial pathogens and sakuranetin is more effective against fungal pathogens
