chitinase-gold complex used to localize chitin ultrastructurally in tomato root cells infected by fusarium oxysporum f. sp. radicis-lycopersici, compared with a chitin specific gold-conjugated lectin.a cytochemical technique for the ultrastructural localization of chitin in tomato root cells infected by fusarium oxysporum f. sp. radicis-lycopersici is reported. chitinase was complexed to colloidal gold and thin sections were incubated with the enzyme-gold complex. this technique yielded a more uniform distribution of gold particles over the fungus wall, compared to that obtained with the lectin-gold technique. both techniques revealed no labelling of the fungus cytoplasm, except for organell ...19852411684
the response of fusarium oxysporum to dithane m-45 and pseudomonas aeruginosa.the interaction of the fungicide dithane m-45 (active ingredient mancozeb), with pseudomonas aeruginosa strain not sensitive to the compound, was studied. pseudomonas aeruginosa produced a fungicidal compound inhibiting the growth of fusarium oxysporum. simultaneously pseudomonas aeruginosa degraded the ebis (ethyleneisothiocyaniane) formed from the spontaneous decomposition of the fungicide which is highly toxic for fusarium oxysporum. when the fungicide was used as seed dressing together with ...19872447753

immunosuppressive effects of dietary wortmannin on rats and order to assess the effects of the fungal toxin wortmannin on the immune system, rats and mice were fed wortmannin-containing cultures of fusarium oxysporum for 1 or 2 weeks. wortmannin caused significant decreases in thymic weight, thymic lymphocyte numbers, serum igg and igm levels, the primary humoral response to t-dependent and t-independent antigens and the proliferative response of spleen cells to pokeweed mitogen. in vitro administration of wortmannin did not produce evidence of cytoto ...19892628478
ultrastructural study of galacturonic acid distribution in some pathogenic fungi using gold-complexed aplysia depilans gonad lectin.aplysia gonad lectin, isolated from the mollusc aplysia depilans, was successfully conjugated to colloidal gold and used for ultrastructural detection of galacturonic acids in some pathogenic fungi. these sugar residues were found to occur in the fibrillar sheath surrounding hyphal cells of ascocalyx abietina and in intravacuolar dense inclusions of this fungus spores. in hyphae and spores of ophiostoma ulmi, galacturonic acids were detected mainly in the outermost wall layers. in contrast, thes ...19892659155
cloning of the nitrate reductase gene (niad) of aspergillus nidulans and its use for transformation of fusarium heterologous transformation system for the phytopathogenic fungus fusarium oxysporum has been developed based on the use of the aspergillus nidulans nitrate reductase gene (niad). f. oxysporum nia- mutants were easily selected by chlorate resistance. the a. nidulans niad gene was isolated from a gene library by complementation of an a. nidulans niad mutant. the cloned gene is capable of transforming f. oxysporum nia- mutants at a frequency of up to ten transformants per microgram of dna. sout ...19892670677
transformation of seven species of filamentous fungi using the nitrate reductase gene of aspergillus nidulans.a gene transfer system originally developed for fusarium oxysporum has been applied to seven species of filamentous fungi of agricultural and industrial importance. this transformation system relies on the selection of mutants deficient in nitrate reductase by positive screening. such mutants were recovered easily in all the fungi tested--without mutagenic treatments--through their resistance to chlorate. they were transformed by a plasmid vector (pan301) carrying the aspergillus nidulans wild-t ...19892673557

mitochondrial dna in fusarium oxysporum is a 46.5 kilobase pair circular molecule.purified mitochondria were obtained from the phytopathogenic fungus fusarium oxysporum f. sp. lycopersici by mechanical disruption of protoplasts, followed by differential and density gradient centrifugation. dna, extracted from the mitochondria, was shown by electron microscopy and restriction endonuclease analysis to be a 46.5 kilobase pair circular molecule.19846098631
lipid involvement in oleoyl coa desaturase activity of fusarium oxysporum microsomes.desaturation of oleoyl coa by the microsomal fraction of fusarium oxysporum hyphal cells required o2, nadph, mgcl2, and the addition of either bovine serum albumin or the 105 000g supernatant fraction. in the absence of reduced nucleotide, [14c]oleoyl coa was rapidly incorporated into phospholipid and triacylglycerol and hydrolyzed to free fatty acids. after addition of nadph, oleate was desaturated at the normal rate. analysis of the distribution of [14c]oleate and [14c]linoleate between differ ...19806104537
8006-i, an antibiotic from amblyosporium spongiosum (pers.) hughes sensu pirozynski. ii. biological properties.8006-i is an antibacterial antibiotic with a rather broad spectrum of activity. the minimum inhibitory concentrations for the most sensitive bacteria are in the range of one to ten micrograms/ml. yeasts are not affected by concentrations up to 100 micrograms/ml. some filamentous fungi like fusarium oxysporum and mucor miehei are inhibited at 100 micrograms/ml. in ehrlich carcinoma ascitic cells the incorporation of uridine and leucine and to a lesser extent that of thymidine is reduced. in isola ...19826178718
development of fluorescent-antibody reagents for demonstration of pseudallescheria boydii in tissues.we prepared fluorescent-antibody reagents to detect and identify pseudallescheria boydii in tissue. antisera to broken mycelium and condidia (particulate antigens) and to culture filtrates (soluble antigens) of p. boydii were produced in rabbits. antisera and globulin fractions of the antisera were labeled with fluorescein isothiocyanate and evaluated for their ability to stain p. boydii in tissues. the conjugates were first tested with cultures of 25 p. boydii isolates and 26 heterologous fungi ...19836195179
a case of nondermatophytic toe onychomycosis caused by fusarium oxysporum.the case history of a patient with nondermatophytic onychomycosis of the great toenail due to fusarium oxysporum is presented. the occurrence of fusarium onychomycosis, although not rare, is infrequent. this fungus may not be recovered from clinical material if the specimen is cultured only on media containing cycloheximide.19806445716
3'-hydroxylation of 4'-methoxyisoflavones by fusarium oxysporum f. lycopersici.3'-hydroxylation of isoflavones by fusarium oxysporum f. lycopersici mainly proceeds with 4'-methoxy-7-hydroxyderivatives; this reaction is used for quantitative conversion of 14c-labelled isoflavones.19836649792
