Osmotic stress-coupled maintenance of polar growth in Aspergillus nidulans.
Free-living cells monitor extracellular 'osmotic strength' and respond metabolically to offset unfavourable osmotic intracellular solute concentrations. Here, we report the reconstruction of the Aspergillus nidulans salt stress-controlling MAP kinase pathway, based on homology analysis with known yeast genes. In A. nidulans, salt stress HOG genes, such as pbsA, hogA, ptpA and msnA, are upregula...
متن کاملComparing artificial and natural selection in rate of adaptation to genetic stress in Aspergillus nidulans.
In an experimental study of adaptation to negative pleiotropic effects of a major fungicide resistance mutation in the filamentous fungus Aspergillus nidulans we have investigated the relative effectiveness of artificial selection vs. natural selection on the rate of compensatory evolution. Using mycelial growth rate as a fitness measure, artificial selection involved the weekly transfer of the...
متن کاملGenomics of Compensatory Adaptation in Experimental Populations of Aspergillus nidulans
Knowledge of the number and nature of genetic changes responsible for adaptation is essential for understanding and predicting evolutionary trajectories. Here, we study the genomic basis of compensatory adaptation to the fitness cost of fungicide resistance in experimentally evolved strains of the filamentous fungus Aspergillus nidulans The original selection experiment tracked the fitness reco...
متن کاملMitotic Recombination Accelerates Adaptation in the Fungus Aspergillus nidulans
Understanding the prevalence of sexual reproduction in eukaryotes is a hard problem. At least two aspects still defy a fully satisfactory explanation, the functional significance of genetic recombination and the great variation among taxa in the relative lengths of the haploid and diploid phases in the sexual cycle. We have performed an experimental study to explore the specific advantages of h...
متن کاملThe tip growth apparatus of Aspergillus nidulans.
Hyphal tip growth in fungi is important because of the economic and medical importance of fungi, and because it may be a useful model for polarized growth in other organisms. We have investigated the central questions of the roles of cytoskeletal elements and of the precise sites of exocytosis and endocytosis at the growing hyphal tip by using the model fungus Aspergillus nidulans. Time-lapse i...
