Multiple signalling pathways mediate fungal elicitor-induced beta-thujaplicin biosynthesis in Cupressus lusitanica cell cultures.

The biosynthesis of a phytoalexin, beta-thujaplicin, in Cupressus lusitanica cell cultures can be stimulated by a yeast elicitor, H(2)O(2), or methyl jasmonate. Lipoxygenase activity was also stimulated by these treatments, suggesting that the oxidative burst and jasmonate pathway may mediate the elicitor-induced accumulation of beta-thujaplicin. The elicitor signalling pathway involved in beta...

Jasmonate and ethylene signalling and their interaction are integral parts of the elicitor signalling pathway leading to beta-thujaplicin biosynthesis in Cupressus lusitanica cell cultures.

Roles of jasmonate and ethylene signalling and their interaction in yeast elicitor-induced biosynthesis of a phytoalexin, beta-thujaplicin, were investigated in Cupressus lusitanica cell cultures. Yeast elicitor, methyl jasmonate, and ethylene all induce the production of beta-thujaplicin. Elicitor also stimulates the biosynthesis of jasmonate and ethylene before the induction of beta-thujaplic...

Lignans from Cupressus lusitanica (Cupressaceae).

Cupressus lusitanica Mill. (Family: Cupressaceae), commonly known as &Mexican cypress' or &Cedar-of-Goa', is an ornamental plant found extensively in Mexico, El Salvador, Guatemala and Honduras, and also in other parts of North and South America (USDA-ARS-GRIN database, 1999). Plant material was collected from Costa Rica and supplied by Biotics Limited, University of Sussex, Brighton, UK. A vou...

Effects of fungal elicitor on lignin biosynthesis in cell suspension cultures of soybean.

Soybean (Glycine max L.) cells cultured in B5 medium produce extremely low amounts of lignin. However, modification in the growth medium, by lowering the concentration of NO(-) (3) and PO(2-) (4), results in the lignification of these cells without affecting levels of cell wall-esterified 4-coumaric and ferulic acid. The production of an extracellular, macromolecular complex by the cultured soy...

Cupressus lusitanica (Cupressaceae) leaf extract induces apoptosis in cancer cells.

A crude ethanolic extract of Cupressus lusitanica Mill. leaves demonstrate cytotoxicity in a panel of cancer cell lines. Cell death was due to apoptosis, as assessed by morphologic features (chromatin condensation and apoptotic bodies formation) and specific DNA fragmentation detected by in situ end-labeling of DNA breaks (TUNEL). The apoptotic cell death was induced timely in a dose-dependent ...
