5-Fluoroanthranilic acid (FAA)-resistant mutants were selected in homothallic diploids of three Saccharomyces species, taking care to isolate mutants of independent origin. Mutations were assigned to complementation groups by interspecific complementation with S. cerevisiae tester strains. In all three species, trp3, trp4 and trp5 mutants were recovered. trp1 mutants were also recovered if the ...
Here we describe a method that allows selective detection of silent copy transcripts in homothallic strains of Schizosaccharomyces pombe in the presence of the active cassettes. The method involving RT-PCR (reverse transcriptase polymerase chain reaction) exploits our observation that the silent copy transcripts extend beyond the regions of homology to the flanking sequences specific for the do...
White-nose syndrome (WNS) of bats has devastated bat populations in eastern North America since its discovery in 2006. WNS, caused by the fungus Pseudogymnoascus destructans, has spread quickly in North America and has become one of the most severe wildlife epidemics of our time. While P. destructans is spreading rapidly in North America, nothing is known about the sexual capacity of this fungu...
GENETIC systems controlling homothallism uersus heterothallism in Saccharomyces yeasts have been reported by several authors ( WINGE and ROBERTS 1949; TAKAHASHI 1958; HERMAN and ROMAN 1966; TAKANO and OSHIMA 1967). Allelism tests indicated that all the homothallism gene systems in S. cereuisiae and its related species are the same (TAKANO and OSHIMA 1970a). The controlling system in these strai...
Mating type genes are central to sexual reproduction and compatibility in Ascomycete fungi. However the "MAT" loci experience unique evolutionary pressures that can result in rapid divergence and enhanced inter-specific gene-flow (lateral gene transfer). In this study, molecular evolution of MAT loci was considered using the genus Fusarium (Teleomorph: Gibberella) as a model. Both MAT1-1 and MA...
A large-scale screen for genes induced during sexual development was performed in the heterothallic oomycete Phytophthora infestans, the potato blight agent. Of 15,644 unigenes on an Affymetrix chip, 87 were induced >10-fold during mating, with 28 induced >100-fold. This was validated in independent matings using RNA blots and RT-PCR. Only 44 genes resembled sequences in GenBank. These encoded ...
