Yeast 1-hybrid screens for upstream regulators of A. thaliana AGO1, AGO7, and AGO10: raw data and R code
<p>These files document a yeast 1-hybrid experiments and associated analyses described in a paper by Hoyer et al. (2019): <a href="https://doi.org/10.1002/pld3.102">https://doi.org/10.1002/pld3.102</a></p> <p>This release corresponds to the fourth version of the Zenodo record. None of the code or data files changed from record 1472704 (the version linked in the paper); I simply added a link to the <a href="https://doi.org/10.1002/pld3.102">Plant Direct paper</a> to the ReadMe file.</p>
Yeast 1-hybrid screens for upstream regulators of A. thaliana AGO1, AGO7, and AGO10: ranked tables of candidate direct upstream TFs
<p>This Excel file supplements a paper by Hoyer et al. (2019): <a href="https://doi.org/10.1002/pld3.102">https://doi.org/10.1002/pld3.102</a></p> <p>The file includes lists of TFs from twelve automated Y1H screens, for user convenience. The first sheet describes the columns. A separate Zenodo record (<a href="https://doi.org/10.5281/zenodo.1345229">1345229</a>) includes the raw data and code showing how the data were processed to generate these twelve tables.</p>

Data from: Extensive recombination of a yeast diploid hybrid through meiotic reversion
In somatic cells, recombination between the homologous chromosomes followed by equational segregation leads to loss of heterozygosity events (LOH), allowing the expression of recessive alleles and the production of novel allele combinations that are potentially beneficial upon Darwinian selection. However, inter-homolog recombination in somatic cells is rare, thus reducing potential genetic variation. Here, we explored the property of S. cerevisiae to enter the meiotic developmental program, induce meiotic Spo11-dependent double-strand breaks genome-wide and return to mitotic growth, a process known as Return To Growth (RTG). Whole genome sequencing of 36 RTG strains derived from the hybrid S288c/SK1 diploid strain demonstrates that the RTGs are bona fide diploids with mosaic recombined genome, derived from either parental origin. Individual RTG genome-wide genotypes are comprised of 5 to 87 homozygous regions due to the loss of heterozygous (LOH) events of various lengths, varying between a few nucleotides up to several hundred kilobases. Furthermore, we show that reiteration of the RTG process shows incremental increases of homozygosity. Phenotype/genotype analysis of the RTG strains for the auxotrophic and arsenate resistance traits validates the potential of this procedure of genome diversification to rapidly map complex traits loci (QTLs) in diploid strains without undergoing sexual reproduction.
Data from: The effect of hybrid transgression on environmental tolerance in experimental yeast crosses
Evidence is rapidly accumulating that hybridization generates adaptive variation. Transgressive segregation in hybrids could promote the colonization of new environments. Here, we use an assay to select hybrid genotypes that can proliferate in environmental conditions beyond the conditions tolerated by their parents, and we directly compete them against parental genotypes in habitats across environmental clines. We made 45 different hybrid swarms by crossing yeast strains (both Saccharomyces cerevisiae and S. paradoxus) with different genetic and phenotypic divergence. We compared the ability of hybrids and parents to colonize seven types of increasingly extreme environmental clines, representing both natural and novel challenges (mimicking pollution events). We found that a significant majority of hybrids had greater environmental ranges compared to the average of both their parents' ranges (mid-parent transgression), but only a minority of hybrids had ranges exceeding their best parent (best-parent transgression). Transgression was affected by the specific strains involved in the cross and by the test environment. Genetic and phenotypic crossing distance predicted the extent of transgression in only two of the seven environments. We isolated a set of potentially transgressive hybrids selected at the extreme ends of the clines and found that many could directly outcompete their parents across whole clines and were between 1.5- and 3-fold fitter on average. Saccharomyces yeast is a good model for quantitative and replicable experimental speciation studies, which may be useful in a world where hybridization is becoming increasingly common due to the relocation of plants and animals by humans.
