Mitochondrial DNA restriction fragment length polymorphisms in field isolates of the Aspergillus niger aggregate.
The mitochondrial DNAs (mtDNAs) and the ribosomal repeat unit (ribosomal DNA, rDNA) of black Aspergillus isolates collected in various parts of the world were examined. Wide-ranging mtDNA variationExpand

Vegetative incompatibility in Neurospora: its effect on horizontal transfer of mitochondrial plasmids and senescence in natural populations
We have investigated the horizontal transfer of two mitochondrial plasmids and the Kalilo senescence phenotype in the fungus Neurospora without the use of heterokaryon-forcing markers. The KaliloExpand

Genetic maps of eight linkage groups of Aspergillus niger based on mitotic mapping
SummaryThis paper provides a genetic map of Aspergillus niger. At present 84 markers have been assigned to eight linkage groups. The chromosomal location of 60 markers is presented in this paper. TheExpand

The ultrastructure and renewal of the intestinal epithelium of the juvenile grasscarp, Ctenopharyngodon idella (Val.)
SummaryThe intestinal absorptive epithelium of starved and fed fish has been studied electron microscopically. After feeding, cells of the proximal segment of the intestine show morphologicalExpand

Genotoxicity of quercetin in cultured mammalian cells.
The naturally occurring flavonol, quercetin, was investigated concerning its ability to induce SCEs and HGPRT-deficient mutants in V79 Chinese hamster cells, and HGPRT- and TK-deficient mutants inExpand

Genetic variability and relatedness in the complex group of black Aspergilli based on random amplification of polymorphic DNA
A PCR-based technique, involving the random amplification of polymorphic DNA (RAPD), was used for assessing genomic variability among a wide range of culture collection strains of black AspergilliExpand

The complete karyotype of Aspergilius niger: the use of introduced electrophoretic mobility variation of chromosomes for gene assignment studies
A method is described for unambiguous assignment of cloned genes to Aspergillus niger chromosomes by CHEF gel electrophoresis and Southern analysis. All of the eight linkage groups (LGs), with theExpand

Isolation and characterization of sexual sporulation mutants of Aspergillus nidulans.
For the genetic dissection of sexual sporulation in Aspergillus nidulans, we started a collection of ascosporeless mutants. After mutagenization of conidiospores with high doses of UV, we isolated 20Expand
