Basic and neutral amino acid transport in Aspergillus nidulans.
Arginine and methionine transport by Aspergillus nidulans mycelium was investigated. A single uptake system is responsible for the transport of arginine, lysine and ornithine. Transport is energy-dependent and specific for these basic amino acids. The Km value for arginine is 1 X 10(-5) M, and Vmax is 2-8 nmol/mg dry wt/min; Km for lysine is 8 X 10(-6) M; Kt for lysine as inhibitor of arginine ...
متن کاملAspergillus 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 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 ...
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 کاملElectrophoretic karyotype of Aspergillus nidulans.
An electrophoretic karyotype of Aspergillus nidulans has been obtained using contour-clamped homogeneous electric field gel electrophoresis. Six chromosomal bands were separated, with two of the bands migrating as doublets. Using the Schizosaccharomyces pombe and Saccharomyces cerevisiae chromosomes as size standards, we estimate the sizes of the chromosomes to be between 2.9 and 5.0 megabase p...
