the mitotic apparatus in fungi, ceratocystis fagacearum and fusarium oxysporum.vegetative nuclei of fungi ceratocystis fagacearum and fusarium oxysporum were studied both in the living condition with phase-contrast microscopy and after fixation and staining by hcl-giemsa, aceto-orcein, and acid fuchsin techniques. nucleoli, chromosomes, centrioles, spindles, and nuclear envelopes were seen in living hyphae of both fungi. the entire division process occurred within an intact nuclear envelope. spindles were produced between separating daughter centrioles. at metaphase the ch ...19694881436
enzymatic reduction of iron oxide by fungi.the occurrence of the iron-reducing phenomenon among some common fungi was studied. results indicated that (i) the reduction of ferric iron to the ferrous state by fungi seems to be restricted to nitrate reductase-inducible strains such as actinomucor repens, alternaria tenuis, fusarium oxysporum, and f. solani and (ii) the amount of dissolved ferrous iron may be reduced progressively by increasing the amount of nitrate added to the medium. compared with a complex medium (sabouraud medium), less ...196916349855
effect of meloidogyne incognita, m. hapla, and m. javanica on the severity of fusarium wilt of chrysanthemum.rooted cuttings of chrysanthemum morifolium 'yellow delaware' (fusarium-susceptible) and 'white iceberg' (fusarium-resistant) were greenhouse-grown in: (i) non-infested soil; (ii) soil infested with fusarium oxysporum alone; (iii) soil infested with meloidogyne incognita, m. javanica or m. hapla; and (iv) each nematode separately plus the fungus. all nematode species infected roots of both cultivars and caused characteristic root-knot symptoms but did not appreciably affect growth meassured by p ...196919325666
antagonistic interaction of heterodera schachtii schmidt and fusarium oxysporum (woll.) on sugarbeets.in a field experiment, nematicides controlled the disease of sugarbeets caused by heterodera schachtii and fusarium oxysporum. biocides that were both fungicidal and nematicidal also controlled the disease, but sugar yields were no higher than those obtained with the plain nematicides. in greenhouse experiments, the interaction between h. schachtii and f. oxysporam was disadvantageous to the nematode. damage to sugarbeets was less when the fungus and the nematode were present than when only the ...197019322329

protein content and amino acid composition of certain fungi evaluated for microbial protein production.the protein and total amino acid contents of four mycelial fungal strains and one yeast were approximately the same for cultures harvested in the mid-log and early stationary growth phases. it was found that fusarium oxysporum and fusarium moniliforme contained approximately 30% more protein and total amino acids than aspergillus niger. the amino acid composition of mycelial protein compares favorably with that of british petroleum yeast protein toprina produced commercially on hydrocarbon subst ...19751115498
fungal air spora at ibadan, nigeria.the fungal air spora at ibadan, nigeria, was investigated by using casella slit samplers. three sites, incorporating three locations at each site, were selected for the exposure of replicate plates during sampling. to provide data on a wide range of saprophytic and pathogenic fungal spores, isolations were made on sabouraud dextrose agar and malt agar plates incubated at 26 and 37 c. altogether over 60,000 fungal colonies were isolated and counted during the 12-month sampling period. the prevale ...19751124919

the effect of volatile and gaseous metabolites of swelling seeds on germination of fungal spores.effects of volatile and gaseous metabolites of swelling seeds of pea, bean, wheat, corn cucumber, tomato, lentil, carrot, red papper and lettuce on germination of spores of five genera of fungi were found to depend rather on the fungal than on the plant genus. germination of spores of botrytis cinerea, mucor racemosus and trichoderma viride was most severely inhibited. spores of verticillium dahliae were less sensitive and germination of spores of fusarium oxysporum was inhibited only in two cas ...19751176038

effect on microorganisms of volatile compounds released from germinating seeds.volatile compounds evolved from germinating seeds of slash pine, bean, cabbage, corn, cucumber, and pea were evaluated for their ability to support growth of microorganisms in liquid mineral salts media lacking a carbon source. growth of eight bacteria was measured turbidimetrically and of six fungi as dry weight of mycelium. volatiles caused increased growth of pseudomonas fluorescens, bacillus cereus, erwinia carotovora, agrobacterium tumefaciens, a. radiobacter, rhizobium japonicum, mucor muc ...19751201509
fusariosis, myasthenic syndrome, and aplastic anemia.fusarium, a fungus, produces a potent mycotoxin that, when ingested with contaminated cereal grains, produces a serious illness in man called alimentary toxic aleukia (ussr) and akakabi-byo (japan). the illness includes gastrointestinal symptoms and weakness and if ingestion of fusarium contaminated grain persists, culminates in aplastic anemia. a 66-year-old woman had eaton-lambert syndrome and a clinical course similar to alimentary toxic aleukia. several months before her death, pancytopenia, ...19751237102

temperature-induced alterations in phospholipids of fusarium oxysporum f. sp. lycopersici.ten phospholipids were identified in hyphal membrane preparations of fusarium oxysporum f. sp. lycopersici when the cells were grown to the late log phase at 15, 25, and 37 degrees c, respectively. the major phospholipids present were phosphatidylcholine (pc) and phosphatidylethanolamine (pe), which together made up about 70% of the total membrane phospholipids. the degree of unsaturation in the acyl group of the phospholipids was inversely related to growth temperature. the polar head group com ...19761260546
characterization of two endopolygalacturonase isozymes produced by fusarium oxysporum f. sp. lycopersici.polygalacturonase (ec 3.2.1.15) produced by fursarium oxysporum f. sp. lycopersici was purified by chromatography on deae-cellulose, cm-cellulose, and hydroxyapatite. the purified enzyme consisted of two electrophoretically distinct "isozymes", that behaved as charge isomers during electrophoresis in several different concentrations of polyacrylamide gel. the two isozymes had similar "endo" modes of action on polygalacturonic acid, as determined by comparison of viscosity reduction, reducing gro ...19761268232
[the palmier date palm and fusarium infection. ii. report on the stereochemistry of monosaccharides and their various derivatives and the growth of fusarium oxysporum f.sp. albedinis (killian et maire) gordon].fusarium oxysporum albedinis was grown in the presence of 20 different sugars or their derivatives. the results obtained were correlated with the stereochemical structure of the main oses. osmotic phenomena as well as active and selective transport were used to explain differences in utilization of oses of very near structure. based on the affinity of the fungus for mannose, a hypothesis is formulated concerning the fungus action in the host.19761276994
properties of spin labelled membranes of fusarium oxysporum f. sp. lycopersici.growth temperature-induced compositional changes in membranes of fusarium oxysporum provided a test system for study of the relationship between physical properties and composition. growth at 15 degrees c was characterized by a decrease in phospholipid content relative to sterol content, a shift in phospholipid composition from phosphatidylcholine to phosphatidylethanolamine and a marked enhancement in the amount of polyunsaturated fatty acids in the phospholipid and triglyceride classes. uptake ...1976182261

heterokaryosis in fusarium oxysporum f.sp. lycopersici.intra-isolate and inter-isolate heterokaryons were synthesized between auxotrophic mutants of fusarium crown rot, 'purple variant' and the wilt isolates. this is the first report of intra- and inter-isolate heterokaryons in fusarium oxysporum f.sp. lycopersici. conidial ratios determined for several heterokaryons between different mutants of the fusarium crown rot organism showed that the ratio is constant for each heterokaryon and that the ratio usually is in favour of one of the mutants.1976932676
