Phytoalexins are specialised antimicrobial metabolites that are produced by plants in response to pathogen attack. Momilactones and phytocassanes are the major diterpenoid phytoalexins in rice and are synthesised from geranylgeranyl diphosphate, which is derived from the methylerythritol phosphate (MEP) pathway. The hyperaccumulation of momilactones and phytocassanes due to the hyperinductive e...

Expression of OsWRKY71, a rice WRKY gene, was induced by biotic elicitors and pathogen infection. It was also found that OsWRKY71 has features characteristic of a transcriptional repressor. Microarray analysis revealed that several elicitor-induced defense-related genes were upregulated in rice cells overexpressing OsWRKY71. These results indicate that the activation of defense-related genes by...

We established a new plant defense response assay using a transient expression system in rice protoplasts. The assay system sensitively detected defense induction by flagellin, which had previously been assigned to a specific elicitor. Our assay system provides a rapid and efficient way to dissect rice defense mechanisms.

The tomato (Lycopersicon esculentum) resistance (R) gene Cf-9 is required for resistance to races of the fungal pathogen Cladosporium fulvum expressing the elicitor Avr9 and also confers responsiveness to Avr9 in Cf-9-containing transgenic tobacco (Nicotiana tabacum; Cf9 tobacco). Although protein phosphorylation is required for many early Avr9/Cf-9-signaling events, so far the only phosphoryla...

A 8jglucan isolated from the mycelial wails of Phytophthora megasperma var. sojae and a glucan purified from yeast extract stimulate the accumulation of phytoalexins in red kidney bean, Phaseolus vulgads, and stimulate the accumulation of the phytoalexin, rishitin, In potato tubers, Solanum tuberosum. These glucans have previously been shown to be potent elicitors of glyceollin accumulation In ...

In this study the effect of different concentrations of some abiotic elicitors (salicylic acid, jasmonic acid, cadmium chloride and sodium chloride) with different incubation times (3, 6, 9 and 12) on azadiractin production and cell growth in the cell culture of the Iranian native Neem were investigated. Cell growth rate was measured by changes in dry cell weight and it was used as a basis for ...

Elicitors could be used as the enhancer of plant secondary-metabolite synthesis and could play an important role in biosynthetic pathways of important medicinal compounds. The present study investigated the effect of abiotic elicitor (fungal extract of Fusarium graminearum) and two abiotic elicitors (methyl jasmonate and salicylic acid) at different concentrations in 18- and 30-day-old cultures...

We report here the effect of increased amount a water-immiscible ionic liquid (IL), 1-butyl-1-methylpyrrolidinium bis(trifluoromethanesulfonyl)imide (P14-TFSI), enhancing production paclitaxel with in situ extraction from an aqueous medium plant cell culture. The productivity culture including IL 10 vol% was 1.5 times greater than that 2.5 vol%. Moreover, addition elicitor, methyl jasmonate (MJ...
