Coronatine elicits phytoalexin production in rice leaves (Oryza sativa L.) in the same manner as jasmonic acid.
The phytotoxin coronatine induced the accumulation of the flavonoid phytoalexins sakuranetin and momilactone A in rice leaves. Coronatine-inducible sakuranetin production was under the control ofExpand

Phytoalexin production elicited by exogenously applied jasmonic acid in rice leaves (Oryza sativa L.) is under the control of cytokinins and ascorbic acid
Jasmonic acid (JA) has been shown to be a signaling compound which elicits the production of secondary metabolites including phytoalexins in plants. It has been shown that the phytoalexin productionExpand

Role of Jasmonic Acid as a Signaling Molecule in Copper Chloride-elicited Rice Phytoalexin Production
Phytoalexins are antimicrobial secondary metabolites which accumulate in plants against fungal invasion. Their production is triggered not only by fungal invasion, but also by a variety of elicitors.Expand

Methionine-induced Phytoalexin Production in Rice Leaves
The application of methionine on wounded rice leaves induced the production of rice phytoalexins, sakuranetin and momilactone A. This induction resulted from stimulation of phenylalanineExpand

Quantification of amino acid conjugates of jasmonic acid in rice leaves by high-performance liquid chromatography–turboionspray tandem mass spectrometry
Abstract HPLC–turboionspray MS–MS (TIS-MS–MS) was shown to be useful in the quantification of the amino acid conjugates of jasmonic acid (JA) as well as free JA in rice leaves. With the TIS-MS–MSExpand

Synthesis of 7-methoxyapigeninidin and its fungicidal activity against Gloeocercospora sorghi.
In the structure of sakuranetin, which was isolated as a phytoalexin from the rice plant, the methoxy group at C-7 has been shown to be important for its high activity. Apigeninidin was isolated as aExpand

Enzymatic synthesis of novel branched sugar alcohols mediated by the transglycosylation reaction of pullulan-hydrolyzing amylase II (TVA II) cloned from Thermoactinomyces vulgaris R-47.
Transglycosylation reactions are useful for preserving a specific sugar structure during the synthesis of branched oligosaccharides. We have previously reported a panosyl unit transglycosylationExpand
