The prenylated flavonoids, topazolin [5,7,4'-trihydroxy-3-methoxy-6-(3,3-dimethylaIlyl)flavone], piscerythrone [5,7,2',4'-tetrahydroxy-5'-methoxy-3'-(3,3-dimethylallyl)isoflavone] and piscidone [5,7,4',5'-tetrahydroxy-2'-methoxy-6'-(3,3-dimethylallyl)isoflavone] were meta­ bolized by Aspergillus flavus and Botrytis cinerea to give a variety of products. Topazolin and piscerythrone were converte...

Several ether and ester derivatives of aryl aldoximes have been synthesized from the aryl aldehydes. Structures of all new products were established by spectral methods. Many of the obtained compounds showed higher activity against fungal pathogens Botrytis cinerea, Fusarium culmorum, Phytophthora cactorum, and Rhizoctonia solani than the reference substance chlorothalonil, reaching 100% inhibi...

Detoxification of an antifungal monoterpene terpinolene (1) by the plant pathogenic fungus Botrytis cinerea afforded hydroxlyated metabolites 2,3-dihydro-3beta,6beta-dihydroxy-terpinolene (2) (39%) and 2,3-dihydro-1alpha,3alpha-dihydroxy-terpinolene (3) (20%), respectively. Terpinolene showed good levels of antifungal activity while both the metabolites were inactive against another plant patho...

Leguminosae, Lathyrus sativus, Phytoalexin, 6a-Hydroxypterocarpan, Pisatin Lathyrus sativus was investigated for the nature of its phytoalexin response with the result that leaflets, im­ mature pods, and seeds were induced to produce 6a-hydroxy-3-methoxy-8,9-methylenedioxypterocarpan (pisatin). Evidence is presented for the metabolism of pisatin, by the wound pathogen Botrytis cinerea, to a phe...

Botrytis cinerea causes gray mold rot on over 200 plant species worldwide, resulting in great economic loss every year. Cooperation of proteins secreted by B. cinerea plays an important role in its successful infection to host plants. The ambient pH, as one of the most important environmental parameters, can regulate expression of secreted proteins in various fungal pathogens. In the present s...
