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 ...

A receptor on soybean membranes for a fungal elicitor of phytoalexin accumulation.

Soybean membrane preparations specifically bound [(14)C]mycolaminaran, a branched beta-1,3-glucan produced by Phytophthora sp. which elicits production of the phytoalexin glyceollin in soybean tissues. A Scatchard plot of the binding data disclosed the presence of a single affinity class of binding sites with a K(d) value of 11.5 micromolar for the glucan. To assess the physiologic importance o...

Nitric oxide mediated the effects of nebivolol in cardiorenal syndrome

Objective(s): Despite several proposed mechanisms for the pathophysiology of cardiorenal syndrome (CRS), the exact mechanism remains unclear. Nitrosative stress has been argued as a key mechanism recently. Nebivolol is a beta-blocker with nitric oxide (NO)-releasing effect. In the present study, NO-mediated effects of two different treatment regimes of nebivolol in CRS...

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...
