| the use of analytical electron microscopy in the study of three species of aspergillaceae. | the combination of electron beam scanning and x-ray detection allows to use the scanning electron probe microanalyzer as a sensitive microscope to elemental constitution. this made it possible to investigate three species of the aspergillus nidulans group: a. nidulans, a. unguis, a. variecolor. qualitative differences were found between the three species. the application of microanalysis is regarded as a useful addition to more conventional methods used in histochemical studies. the advantages o ... | 1975 | 787898 |
| characterization of interspecific hybrids within the aspergillus nidulans group by isoenzyme analysis. | a comparison of interspecific hybrids within the aspergillus nidulans species group was made by isoenzyme analysis. the gel electrophoretic patterns of the parental species were distinct for most of the enzymes tested. the hybrids were distinguishable from their parents by isoenzyme patterns. the appearance of novel bands in all the interspecific hybrids indicated that nuclear fusion could have occurred. in most hybrids the appearance of the parental bands showed nonpreferential, partial chromos ... | 1991 | 1878817 |
| further studies on protoplast fusion and interspecific hybridization within the aspergillus nidulans group. | hybridization of eight species of the aspergillus nidulans group was attempted using auxotrophic mutants and protoplast fusion methods. viable fusion products were obtained from eight crosses. allodiploid hybrids were recovered from crosses involving a. nidulans with a. rugulosus, a. quadrilineatus, a. nidulans var. echinulatus and a. violaceus, although some mutants only gave heterokaryons. crosses involving these latter species also gave heterokaryons. crosses between a. nidulans and a. unguis ... | 1984 | 6389760 |
