| antifungal compounds induced in the dual culture with phytolacca americana callus and botrytis fabae. | in order to investigate new metabolites which are only induced in a plant callus infected by a pathogenic fungus, dual cultures with combinations of 10 species of fungi and 6 plant cell lines from different species were established. among the combinations tested, the methanolic extract of a dual culture consisting of a plant cell line, phytolacca americana and a fungus, botrytis fabae showed a marked antifungal activity to cladosporium herbarum. the main active constituent of this extract was id ... | 1995 | 7546032 |
| inhibition of phosphatidylcholine and chitin biosynthesis in pyricularia oryzae, botrytis fabae and fusarium graminearum by edifenphos. | colony growth of the fungi pyricularia oryzae, botrytis fabae and fusarium graminearum was reduced by 50% (ed50) by edifenphos concentrations of 7, 25 and 190 microm respectively; the phosphatidylcholine (pc) content of biomass of p. oryzae, b. fabae, and f. graminearum harvested from fungicide-containing-cultures was reduced by 50% by 6, 95 and 350 microm-edifenphos respectively. by contrast, the activities of membrane-bound chitin synthase preparations isolated from the three fungi were approx ... | 1993 | 8360628 |
| generation of superoxide anion and induction of superoxide dismutase and peroxidase in bean leaves infected with pathogenic fungi. | generation of superoxide anion (o2-.) and peroxidase activity were significantly increased in bean leaves infected with incompatible and compatible pathogens: botrytis fabae and botrytis cinerea, respectively, but the induction was greater on direct inoculation with b. fabae, than with b. cinerea. a slightly higher o2-. level was also detected in the parts of leaves surrounding the inoculation side. overproduction of o2-. was observed earlier than the increase in peroxidase activity. pretreatmen ... | 1996 | 9104504 |
| characterization of molecular markers for specific and sensitive detection of botrytis cinerea pers.: fr. in strawberry (fragariaxananassa duch.) using pcr. | random amplified polymorphic dna (rapd) assays were applied on 34 fungal strains isolated from strawberry and other host plants, in order to detect polymorphism to consequently identify and isolate molecular markers specific to botrytis cinerea. among the 26 10-mer primers tested, one primer mainly amplified a 750-bp product present in all the b. cinerea strains and absent in the other species and genera examined. this product was cloned and sequenced in order to design a specific 20-mer primer ... | 2002 | 12007801 |

| altered growth and polyamine catabolism following exposure of the chocolate spot pathogen botrytis fabae to the essential oil of ocimum basilicum. | biomass of the fungal pathogen botrytis fabae in liquid culture amended with two chemotypes of the essential oil of basil, ocimum basilicum, was reduced significantly at concentrations of 50 ppm or less. the methyl chavicol chemotype oil increased the activity of the polyamine biosynthetic enzyme s-adenosylmethionine decarboxylase (adometdc), but polyamine concentrations were not significantly altered. in contrast, the linalol chemotype oil decreased adometdc activity in b. fabae, although again ... | 2005 | 16392245 |

| synthesis and antimicrobial activity of some new 4-hetarylpyrazole and furo[2,3-c]pyrazole derivatives. | in continuation of our efforts to find a new class of antimicrobial agents, a series of 4-hetarylpyrazoles and furo[2,3-c]pyrazoles were prepared via the reaction of 2-chloro-1-(5-hydroxy-3-methyl-1-phenyl-1h-pyrazol-4-yl)ethanone (1) with an appropriate nucleophilic reagents. these compounds were screened for their antibacterial activity against gram-positive bacteria (bacillus subtilis and bacillus thuringiensis), gram-negative bacteria (escherichia coli and pseudomonas aeruginosa) and antifun ... | 2011 | 21489661 |
| botrytone, a new naphthalenone pentaketide produced by botrytis fabae, the causal agent of chocolate spot disease on vicia faba. | a strain of botrytis fabae isolated from faba bean (vicia faba l.) plants displaying clear chocolate spot disease symptoms, produced phytotoxic metabolites in vitro. the phytotoxins isolated from the culture filtrates organic extract were characterized by spectroscopic and optical methods. a new naphthalenone pentaketide, named botrytone, was isolated and characterized as (4r)-3,4-dihydro-4,5,8-trihydroxy-1(2h)naphthalenone together with other well-known closely related naphthalenones such as re ... | 2011 | 21780794 |
| synthesis and antimicrobial activity of some new benzo and naphthonitrile derivatives. | the reaction of 2-(cyanomethyl)benzonitrile (1) with different diazonium salts gave the corresponding aryldiazenyl derivatives 2a-e which reacted with sodium hydroxide and ethyl chloroacetate and hydroxylamine hydrochloride to afford the corresponding acetamides 4a-e, pyrazoloisoquinolines 6a-e and triazoloisoquinoline derivatives 8a-e, respectively. moreover, the reaction of 1 with arylidene malononitriles 9a-c afforded dihydronaphthalenes 11a, b and naphthalene derivative 12, respectively. the ... | 2012 | 23318903 |
