Yes, Ecology can improve Genomics

Blogging on Peer-Reviewed ResearchFew organisms are as well understood at the genetic level as Saccharomyces cerevisiae. Given that there are more yeast geneticists than yeast genes and exemplary resources for the community (largely a result of their size), this comes as no surprise. [...]

Fusarium graminearum genome published

The genome of the wheat and cereal pathogen Fusarium graminearum was published in Science this week in an article entitled “The Fusarium graminearum Genome Reveals a Link Between Localized Polymorphism and Pathogen Specializationtion”. The project was a collaboration of many different Fusarium research groups. [...]

Postia annotation

Not sure when this went live but the Postia placenta annotation is available on the JGI site. 17k genes are predicted which is in the neighborhood of Laccaria. [...]

Yeast genome: Known knowns, and known unknowns

From Genetics this week a review discusses Why are there still 1000 Uncharacterized Yeast genes? Poor Yeast – so many more genes have no known function, while S. pombe has nearly 100% coverage in functional annotation. I’ll also point out that the 1000 genes refers to protein-coding genes, not ncRNA genes which may mean that there is alot more that is unknown. [...]

Orthology detection software

Blogging about Peer-Reviewed Research A paper in PLoS One, Assessing Performance of Orthology Detection Strategies Applied to Eukaryotic Genomes, reports a new approach to assess the performance of automated orthology detection. These authors also wrote the OrthoMCL (2006 DB paper, 2003 algorithm paper) which uses MCL to build orthologous gene families. [...]

That was a lot of work

I’ve never worked with Magnaporthe grisea, the fungus responsible for rice blast, one of the most devastating crop diseases, but I do know that its life cycle is complicated and that knocking out roughly 61% of the genes in the genome and evaluating the mutant phenotype to infer gene function is not trivial. In their recent letter to Nature, Jeon et al did what many [...]

SGD community annotation

The Saccharomyces Genome Database has deployed a wiki for gene annotation from the community.  This should be an interesting experiment in how information can flow from the community into these databases. [...]

Approaching 100% coverage for GO assignments in S.pombe

S. pombe taken from http://www.steve.gb.com/science/spectroscopy.htmlA paper by Martin Aslett and Val Wood indicate that the fission yeast community is approaching 100% coverage of a GO annotation for every gene in the S. pombe genome. Only Ashbya gossypii has a smaller genome in the fungi (see a recent paper [...]

Wikis for genome (re)annotation

Steven Salzberg (who is nominated for the Franklin award at bioinformatics.org) has an opinion piece in Genome Biology proposing wiki technology to help solve the problem of genome annotations getting out of date.

The problem comes down to how annotations are banked. Some people regard GenBank as the gold standard master for annotations, but it only provides a bank. [...]
