Aspergillus nidulans
Light-dependent conidiation in the filamentous ascomycete, Aspergillus nidulans, is contingent on the allelic state of the velvet (veA) gene. Light dependence is abolished by a mutation in this gene (veAl) , which allows conidiation to occur in the absence of light. We have isolated and characterized six extragenic suppressors of veAl that restore the light-dependent conidiation phenotype. Alle...
متن کاملMitosis in Aspergillus nidulans.
Mitosis in growing hyphae of haploid and diploid Aspergillus nidulans has been studied with the light microscope in Helly-fixed preparations. At the periphery of the nucleus a sharply defined granule is invariably found which has strong affinity for acid fuchsin. Mitosis begins with the duplication of this granule and the development inside the nucleus of a gradually lengthening fibre between t...
متن کاملLactose and D-galactose catabolism in the filamentous fungus Aspergillus nidulans.
The disaccharide lactose is a byproduct of cheese production accumulating to amounts of 800,000 tons per year worldwide, of which 15% is used as a carbon source for various microbial fermentations. Nevertheless, little is known about the regulation of its metabolism in filamentous fungi. Lactose is metabolized slowly, and some important fungi such as A. niger cannot use it at all. A more detail...
متن کاملRegulatory genes controlling fatty acid catabolism and peroxisomal functions in the filamentous fungus Aspergillus nidulans.
The catabolism of fatty acids is important in the lifestyle of many fungi, including plant and animal pathogens. This has been investigated in Aspergillus nidulans, which can grow on acetate and fatty acids as sources of carbon, resulting in the production of acetyl coenzyme A (CoA). Acetyl-CoA is metabolized via the glyoxalate bypass, located in peroxisomes, enabling gluconeogenesis. Acetate i...
متن کاملTransformation of Aspergillus nidulans
Aspergillus nidulans strain G191 was transformed to hygromycin resistance using plasmid pDH25, which contains the bacterial hygromycin B phosphotransferase gene (hph) fused to promoter elements of the A. nidulans trpC gene. Southern hybridizations of transformants revealed multiple, integrated copies of the vector. A pleiotropic effect conferring increased hygromycin B sensitivity was found to ...
