The Ashbya gossypii Genome as a Tool for Mapping the Ancient Saccharomyces cerevisiae Genome

TLDR
The genome of the filamentous ascomycete Ashbya gossypii provided compelling evidence that the evolution of S. cerevisiae included a whole genome duplication orfusion of two related species and showed which of the duplicated genes lost one copy and which retained both copies.
Abstract
We have sequenced and annotated the genome of the filamentous ascomycete Ashbya gossypii. With a size of only 9.2 megabases, encoding 4718 protein-coding genes, it is the smallest genome of a free-living eukaryote yet characterized. More than 90% of A. gossypii genes show both homology and a particular pattern of synteny with Saccharomyces cerevisiae. Analysis of this pattern revealed 300 inversions and translocations that have occurred since divergence of these two species. It also provided compelling evidence that the evolution of S. cerevisiae included a whole genome duplication or fusion of two related species and showed, through inferred ancient gene orders, which of the duplicated genes lost one copy and which retained both copies.

MCScanX: a toolkit for detection and evolutionary analysis of gene synteny and collinearity

TL;DR: The MCScanX toolkit implements an adjusted MCScan algorithm for detection of synteny and collinearity that extends the original software by incorporating 14 utility programs for visualization of results and additional downstream analyses.

Genome duplication in the teleost fish Tetraodon nigroviridis reveals the early vertebrate proto-karyotype

TL;DR: Genome analysis provides a greatly improved fish gene catalogue, including identifying key genes previously thought to be absent in fish, and reconstructs much of the evolutionary history of ancient and recent chromosome rearrangements leading to the modern human karyotype.

The genome sequence of the filamentous fungus Neurospora crassa

TL;DR: A high-quality draft sequence of the N. crassa genome is reported, suggesting that RIP has had a profound impact on genome evolution, greatly slowing the creation of new genes through genomic duplication and resulting in a genome with an unusually low proportion of closely related genes.

Genome evolution in yeasts

TL;DR: Analysis of chromosome maps and genome redundancies reveal that the different yeast lineages have evolved through a marked interplay between several distinct molecular mechanisms, including tandem gene repeat formation, segmental duplication, a massive genome duplication and extensive gene loss.

Molecular evidence for an ancient duplication of the entire yeast genome

TL;DR: A model is proposed in which this species is a degenerate tetraploid resulting from a whole-genome duplication that occurred after the divergence of Saccharomyces from Kluyveromyces, and protein pairs derived from this duplication event make up 13% of all yeast proteins.

TL;DR: The genome of fission yeast (Schizosaccharomyces pombe), which contains the smallest number of protein-coding genes yet recorded for a eukaryote, is sequenced and highly conserved genes important for eukARYotic cell organization including those required for the cytoskeleton, compartmentation, cell-cycle control, proteolysis, protein phosphorylation and RNA splicing are identified.

Three biotechnical processes using Ashbya gossypii, Candida famata, or Bacillus subtilis compete with chemical riboflavin production.

TL;DR: The production of riboflavin by the two fungi seems to be limited by precursor supply, as was concluded from feeding and gene-overexpression experiments, and the major limitation there seems to to be the rib oflavin pathway.
