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
