Asexual recombination in a uvsH mutant of Aspergillus nidulans.
Mutations in the gene uvsH of Aspergillus nidulans result in increased spontaneous chromosome instability and increased intragenic and intergenic mitotic recombination in homozygous diploids. The aim of the present work was to obtain a uvs mutant of A. nidulans and to use it for the isolation of asexual recombinants (parameiotic segregants). The mutant uvsH, named B511, showed normal frequency ...
متن کاملhymA (hypha-like metulae), a new developmental mutant of Aspergillus nidulans.
Asexual fruiting body development in Aspergillus nidulans requires a precise spatial and temporal coordinated expression of many genes. Insertional mutagenesis was used to isolate and characterize a new mutant of A. nidulans in which hyphal growth was slightly reduced and conidiophore development was specifically blocked at the metula stage. In contrast to the uninucleate metulae of the wild-ty...
متن کاملWild-type and mutant stocks of Aspergillus nidulans.
VER the past decade the homothallic ascomycete Aspergillus nidulans has become an important organism for genetic investigation. As a consequence of the pioneering research of PROFESSOR G. PONTECORVO and associates, a wide variety of mutant strains have become available for research and teaching. Recognizing these facts, the Committee on the Maintenance of Genetic Stocks of the Genetics Society ...
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 کاملMolecular Characterization of Different Species of Aspergillus nidulans Group
The present study deals with the phylogenetic analysis of A. nidulans group and assay of how much A. aegyptiacus belongs to A. nidulans group or A. versicolor group. The revealed results can be summarized as follows: 1The eight fungal isolates used in this investigation were identified as two isolates of Aspergillus aegyptiacus (AUMC 6122 & 3603),E. nidulans (AUMC152), E. rugulosa (AUMC164), E....
