phase-specific genes for macroconidiation in neurospora crassa.two new mutant genes in neurospora crassa prevent the formation of free macroconidia from proconidial chains. these genes, called conidial separation-1 and conidial separation-2, are phase-specific, playing no role in either the sexual life cycle or other aspects of the asexual life cycle. a cell-wall-associated autolytic activity was found to increase in wild-type cultures at the time of active formation of free conidia from proconidial chains; no such increase was detected in mutant cultures. ...19744280981
regulation of phosphate metabolism in neurospora crassa: isolation of mutants deficient in ther repressible alkaline phosphatase.mutants of neurospora crassa have been isolated that lack the repressible alkaline phosphatase, but, unlike nuc-1 and nuc-2 mutants, are able to make the repressible acid phosphatase and the repressible phosphate permease under conditions of derepression (phosphate deprivation). the new mutants, called pho-2, map in linkage group v, and are unlinked to the putative control mutants, nuc-1, nuc-2-pcon(c), and preg(c). three of the pho-2 mutants do not make detectable amounts of repressible alkalin ...19744280980

cross-pathway regulation: tryptophan-mediated control of histidine and arginine biosynthetic enzymes in neurospora neurospora crassa, the starvation of tryptophan mutants for tryptophan resulted in the derepression of tryptophan, histidine, and arginine biosynthetic enzymes. this tryptophan-mediated derepression of histidine and arginine biosynthetic enzymes occurred despite the fact that the tryptophan-starved cells had a higher intracellular concentration of histidine and arginine than did nonstarved cells.19744368541
cross-pathway regulation: histidine-mediated control of histidine, tryptophan, and arginine biosynthetic enzymes in neurospora neurospora crassa, histidine starvation of histidine mutants resulted in derepression of histidine, tryptophan, and arginine biosynthetic enzymes. the same tripartite derepression occurred in wild-type strain 74a when it was grown in medium supplemented with 3-amino-1,2,4-triazole, an inhibitor of histidine biosynthesis. histidine-mediated derepression of tryptophan and arginine biosynthetic enzymes was not due to a lowered intracellular concentration of tryptophan or arginine, respectively. ...19744368540

a direct comparison between circadian and noncircadian rhythms in neurospora crassa.a method has been devised for observing both circadian and noncircadian rhythms in a single wild type strain of neurospora crassa. this method allows a direct comparison of the properties of the two types of rhythm. the circadian rhythm of conidiation always entrains to a light-dark cycle, damps out in constant light, and has a temperature-compensated period length. the noncircadian rhythm of hyphal branching, expressed by the same strain under different environmental conditions, does not entrai ...197416658817
occurrence of n-formylkynurenine in extracts of neurospora crassa: evidence for the activity of tryptophan pyrrolase.n-formylkynurenine and kynurenine have been detected in extracts of tryptophan-grown neurospora crassa. when the mycelia were grown in medium supplemented with l-[2-(14)c]tryptophan, the radioactivity was detected in n-formylkynurenine and n-formylanthranilic acid; with l-[beta-(14)c]tryptophan, radioactivity was detected in n-formylkynurenine, kynurenine, kynurenic acid, and xanthurenic acid. the occurrence of n-formylkynurenine in extracts of tryptophan-grown neurospora is interpreted as direc ...19744275312

circadian rhythms of nucleic acid metabolism in neurospora crassa.wild-type, band, and fluffy strains of neurospora crassa exhibit circadian rhythms of ribonucleic acid and deoxyribonucleic acid content in the growth-front hyphae of cultures grown on a solid medium. there is also a rhythm of (3)h-uridine incorporation into the nucleic acids of the band strain. maximum incorporation precedes the peaks of nucleic acid content which occur during conidiation. as cultures age, ribonucleic acid content decreases rapidly and deoxyribonucleic acid content decreases gr ...19744273317
isolation and characterization of low-kynureninase mutants of neurospora crassa.two kynureninase activities are known in neurospora crassa, one of which (kynureninase i) is inducible, the other (kynureninase ii) being constitutive. a method is described for the isolation of low-kynureninase mutants of n. crassa. when grown on an inducer, the mutants show significantly less kynureninase i activity compared with wild type, whereas constitutive kynureninase ii activity is unaffected. since a low level of kynureninase i activity remains in the mutants examined, the mutations ma ...19744273316

a failure to detect an influence of magnetic fields on the growth rate and circadian rhythm of neurospora crassa.low strength magnetic fields, 6.36 and 32.25 gauss, were found to have no effect, with one questionable exception, on the circadian rhythm and growth rate of neurospora crassa. this was true whether the fields were continuous, pulsed 20 minutes daily, or on a 12: 12, on-off cycle.197416658667
studies of respiratory components and oxidative phosphorylation in mitochondria of mi-1 neurospora crassa.oxidative phosphorylation has been demonstrated with mitochondria of the mi-1 respiratory mutant of neurospora crassa. the p/o ratios observed with these mitochondria were approximately 0.8 with citrate and 0.4 with either externally added reduced nicotinamide adenine dinucleotide (nadh), succinate, or ascorbate-tetramethyl-p-phenylenediamine (tpd). these p/o ratios suggest that there are only two sites of phosphorylation in mitochondria isolated from young (20 to 24 h) cultures of the mi-1 muta ...19744359654
ethylene glycol-induced alteration of conidial germination in neurospora nutrient medium containing 3.22 m ethylene glycol or glycerol, conidia of neurospora crassa grow as single cells, without forming the germ tubes characteristic of normal morphological germination. ethylene glycol is more effective than glycerol in producing this response. after growth in ethylene glycol medium for a suitable time, the cells are easily disrupted by an abrupt decrease in osmotic pressure. osmotic disruption yields intact nuclei and mitochondria, although mitochondrial fractions ...19744359649
