Elicitor-stimulated ion fluxes and O2- from the oxidative burst are essential components in triggering defense gene activation and phytoalexin synthesis in parsley.

Fungal elicitor stimulates a multicomponent defense response in cultured parsley cells (Petroselinum crispum). Early elements of this receptor-mediated response are ion fluxes across the plasma membrane and the production of reactive oxygen species (ROS), sequentially followed by defense gene activation and phytoalexin accumulation. Omission of Ca2+ from the culture medium or inhibition of elic...

Elicitation of Pterocarpan Phytoalexins in Cell Suspension Cultures of Different Chickpea (Cicer arietinum L.) Cultivars by an Elicitor from the Fungus Ascochyta rabiéi

Cell suspension cultures of two chickpea (Cicer arietinum L.) cultivars, resistant and susceptible towards the chickpea pathogen Ascochyta rabiei, were compared with regard to elicitor-induced changes in phytoalexin and isoflavone accumulation. The elicitor was isolated from fermentergrown mycelium of A. rabiei and it mainly consisted of glucose, mannose and N-acetylgalactosamin. Time course an...

Nitric oxide synthase-mediated phytoalexin accumulation in soybean cotyledons in response to the Diaporthe phaseolorum f. sp. meridionalis elicitor.

Phytoalexin biosynthesis is part of the defense mechanism of soybean (Glycine max) plants against attack by the fungus Diaporthe phaseolorum f. sp. meridionalis (Dpm), the causal agent of stem canker disease. The treatment of soybean cotyledons with Dpm elicitor or with sodium nitroprusside (SNP), a nitric oxide (NO) donor, resulted in a high accumulation of phytoalexins. This response did not ...

Phytoalexin Production by Isolated Soybean Protoplasts

Protoplasts, Soybean Cell Suspension Cultures, Phytoalexin Production, Phytophthora megasperm a f. sp. glycinea, Glucan Elicitor Protoplasts isolated enzymatically from suspension-cultured cells of soybean (Glycine max L. Merr., cv. Harosoy 63) were used to study the production of the isoflavonoid-derived phytoale­ xin, glyceollin. A large enhancement in the in vivo rates of synthesis and catal...

Host-Pathogen Interactions : XXI. Extraction of a Heat-Labile Elicitor of Phytoalexin Accumulation from Frozen Soybean Stems.

An extract of frozen and thawed soybean (Glycine max L. Merr. cv. Wayne) stems is active, in wounded soybean cotyledons, as a heat-labile elicitor of phytoalexins. The elicitor activity of the extract is destroyed by heating to 95 degrees C for 10 minutes. The fraction that contains heat-labile elicitor activity releases heat-stable elicitor-active molecules from purified soybean cell walls. He...
