autogenous regulation of gene expression.a new term, autogenous regulation, is used to describe a phenomenon that is not a new discovery but rather is newly appreciated as a mechanism common to a number of systems in both prokaryotic and eukaryotic organisms. in this mechanism the product of a structural gene regulates expression of the operon in which that structural gene resides. in many (perhaps all) cases, the regulatory gene product has several functions, since it may act not only as a regulatory protein but also as an enzyme, str ...19744589900

mutants of the pentose phosphate pathway in aspergillus nidulans.mutants of the pentose phosphate pathway have been isolated in aspergillus nidulans. these fail to grow on a variety of carbohydrates that are catabolized through the pentose phosphate pathway. they also grow poorly on nitrate and nitrite as sole nitrogen sources. the pentose phosphate pathway mutations have been assigned to two unlinked genes. mutants with lesions in the pppb locus have reduced activities of four enzymes of the pentose phosphate pathway, of glucose-phosphate isomerase, and of m ...19744591946

genetic analysis of the reciprocal translocation t2(i;8) of asperigillus using the technique of mitotic mapping in homozygous translocation diploids.a uv-induced sulphite-requiring mutant (sd50) consistently shows mitotic linkage to groups i and viii in haploids from heterozygous mapping diploids. this linkage was found to be due to a reciprocal translocation t2(i;viii) which could not be separated from the sulphite requirement in about 100 tested progeny from heterozygous crosses, and both may well have been induced by the same mutational event. t2(i;viii) is the first case of a reciprocal translocation in aspergillus which showed meiotic l ...19744601437

regulatory aspects of l-glutamate transport in aspergillus nidulans.wild-type cells of aspergillus nidulans synthesize a transport system which appears to be specific for l-glutamate and l-aspartate. the system is energy dependent and concentrates l-glutamate at least 60-fold. in cells grown in the presence of 1% sucrose, l-glutamate uptake activity is regulated by ammonium control, although it is not certain whether this is at the level of transcription or translation. mutants that are insensitive to ammonium control of certain other unrelated systems, e.g., ni ...19744605030

effects of ammonium, l-glutamate, and l-glutamine on nitrogen catabolism in aspergillus nidulans.during growth of aspergillus nidulans in medium containing ammonium the specific activities of most enzymes involved in catabolism of nitrogen sources are low (ammonium repression). the gdha10 lesion, which results in loss of nicotinamide adenine dinucleotide phosphate-linked glutamate dehydrogenase activity, has been shown to lead to partial relief of ammonium repression of three amidase enzymes as well as histidase. the area102 lesion led to altered levels of these enzymes but did not greatly ...19744612004

use of the immunodiffusion test in the serodiagnosis of aspergillosis.the diagnostic value of an immunodiffusion (id) test with standardized precipitinogens derived from five aspergillus species was determined with sera from 60 proven and 12 suspected cases of aspergillosis. the data demonstrated that the greatest number of aspergillosis cases were detected by the concurrent use of a. fumigatus and a. niger precipitinogens. with these precipitinogens, the id test permitted the serodiagnosis of aspergillosis in 82% of the 60 proven cases and in 83% of the 12 suspec ...19724622826

photooxidative death in blue-green algae.when incubated in the light under 100% oxygen, wild-type blue-green algae (anacystis nidulans, synechococcus cedrorum) die out rapidly at temperatures of 4 to 15 c, and at 35 c (or at 26 c in the case of s. cedrorum) in the absence of co(2). photosynthesis is impaired in these cells long before they die. blocking of photosystem ii at high temperatures in the presence of co(2) sensitizes the algae to photooxidative death. photooxidative death and bleaching of photosynthetic pigments are separable ...19724626540
