synchrony of nuclear replication in individual hyphae of aspergillus nidulans. | the synchrony of nuclear replication in individual, multinucleate hyphae of aspergillus nidulans has been investigated. samples were taken from cultures of germinating conidiospores, and the relative frequency of hyphae containing two to eight nuclei was determined. because the conidiospores are mononucleate, complete synchrony will yield populations of hyphae containing only 2(n) nuclei, n being the number of doublings after germination. the appearance of hyphae with total numbers of nuclei oth ... | 1967 | 6057801 |

kinetic studies of the induction of nitrate reductase and cytochrome c reductase in the fungus aspergillus nidulans. | in an earlier paper (cove, 1966) it was reported that the kinetics of appearance of nitrate reductase (nadph-nitrate oxidoreductase, ec 1.6.6.3) on the addition of nitrate to a growing culture of aspergillus nidulans were different in certain respects from those found for many escherichia coli enzymes. when urea is used as an initial nitrogen source, a further difference is found: enzyme synthesis is no longer continuous. this interruption of synthesis does not appear to be due to synchronous ce ... | 1967 | 6049855 |
inhibition of the lysis of fungi by melanins. | evidence is presented that the resistance of aspergillus nidulans hyphae to lysis by a beta-(1-->3) glucanase-chitinase mixture results from the presence of melanin in the fungal walls. the resistance of the walls to digestion was directly correlated with the melanin content of the mycelium. a melanin-less mutant of a. nidulans was highly susceptible to hydrolysis by the enzyme mixture. preincubation of a synthetic melanin with the glucanase, chitinase, and a protease, before addition of the sub ... | 1967 | 6035264 |

use of analogues and the substrate-sensitivity of mutants in analysis of purine uptake and breakdown in aspergillus nidulans. | aspergillus mutants resistant to various purine analogues (purine, 8-azaguanine, 2-thioxanthine, and 2-thiouric acid) are defective in at least one step of purine uptake or breakdown. the properties of these mutants show that there are two uptake systems for purines, one which mediates the uptake of hypoxanthine, guanine, and adenine, and the other, xanthine and uric acid. allantoinase-less strains are sensitive to the toxic effects of allantoin accumulation. they are severely inhibited when gro ... | 1967 | 6025432 |

phosphatase mutants in aspergillus nidulans. | three mutants at three different phosphatase loci produce inactive enzymes at 35 degrees c but partially or fully active enzynmes at 25 degrees c. furthermore, a suppressor mutant (su5pala1) which restores alkaline phosphatase activity in the pala1 mtutant is an allele of palcc4, a mzutant with a simultaneous reduction in alkaline and acid phosphatase activity. these data suggest that the phosphataseproteins may be made up of two or more different polypeptide chains, and that some of the polypep ... | 1965 | 5852975 |

organization of enzymes in the common aromatic synthetic pathway: evidence for aggregation in fungi. | centrifugation in sucrose density gradients of partially purified extracts from six species of fungi, i.e., rhizopus stolonifer, phycomyces nitens, absidia glauca (phycomycetes), aspergillus nidulans (ascomycetes), coprinus lagopus, and ustilago maydis (basidiomycetes), indicate that the five enzymes catalyzing steps two to six in the prechorismic acid part of the polyaromatic synthetic pathway sediment together. the sedimentation coefficients for these enzymes are very similar in the six specie ... | 1969 | 5802608 |
permeability properties of aspergillus nidulans protoplasts. | the regeneration of mycelial forms from protoplasts of mutant and wild-type strains of aspergillus nidulans was followed microscopically under conditions with which the rate of regeneration depends upon a specific transport function. this method has shown that at least four uptake systems-one for divalent anions, two for purines, and one for sugars-remain functional after removal of the cell wall. | 1969 | 5802597 |

methylammonium resistance in aspergillus nidulans. | mutants of aspergillus nidulans resistant to methylammonium toxicity are simultaneously derepressed in the presence of ammonium for apparently all ammonium-repressible activities. enzyme assays directly demonstrate derepression of nitrate, nitrite, and hydroxylamine reductases, xanthine dehydrogenase, urate oxidase, and allantoinase, whereas in vivo tests show that ammonium and methylammonium repression or inhibition (or both) is relieved in these mutants in pathways of nitrate assimilation, pur ... | 1969 | 5788705 |
autoregulation of the synthesis of nitrate reductase in aspergillus nidulans. | in aspergillus nidulans, the syntheses of nitrate and nitrite reductases are induced by nitrate, and are repressed by ammonium. it is possible in wild-type strains to overcome partially the repressive effect of ammonium, by the addition of high concentrations of nitrate to the growth medium. mutations which lead to the production of abnormal nitrate reductase affect in addition the control of the synthesis of the nitrate-metabolizing enzymes, which in these strains are produced constitutively. t ... | 1969 | 5776531 |

nonrandom sister chromatid segregation and nuclear migration in hyphae of aspergillus nidulans. | radioactive conidiospores of aspergillus nidulans were prepared by growing a purine-requiring mutant with tritiated adenine. when these spores germinated in a nonradioactive medium, the dispersion of the original chromosome set could be followed by treating the hyphae with ribonuclease and preparing radioautograms. germinating spores with four or eight nuclei contained two highly labeled nuclei and two or six nuclei with much less or no radioactivity. successive mitotic divisions thus distribute ... | 1968 | 5685997 |

regulation and timing of deoxyribonucleic acid synthesis in hyphae of aspergillus nidulans. | pulse labeling of deoxyribonucleic acid (dna) and radioautography have been used to study the effect of growth rate on nuclear replication in aspergillus nidulans. when conidia were germinated in media supporting a fast growth rate, the radioactive pulse labeled either all of the nuclei in a cell or none of them. at slower growth rates, hyphae contained both labeled and unlabeled nuclei. altering the growth rate thus changed nuclear replication from simultaneous to sequential. the time taken to ... | 1968 | 5669900 |

regulation of choline sulphatase synthesis and activity in aspergillus nidulans. | 1. choline o-sulphate is taken up from the growth medium to the same extent by sulphur-deficient and sulphur-sufficient mycelia of aspergillus nidulans, but hydrolysis of the transported sulphate ester in vivo only occurs in the sulphur-deficient mycelia. 2. choline sulphatase activity could not be detected in vitro in sulphur-sufficient mycelia of wild-type and sulphur mutants of a. nidulans, but after sulphur starvation all strains showed appreciable activity of this enzyme. 3. optimum activit ... | 1968 | 5637354 |
