A new and improved annotation of Cryptococcus neoformans var grubii strain H99 (serotype A) has been made available in GenBank and the Broad Institute website. This update is collaboration between several groups providing data and analyses and the annotation team at Broad’s gene calling pipeline.

A paper (Park et al, BMC Genomics) from Fungal Bioinformatics Lab at Seoul University in South Korea describes their new “Fungal P450 Database”. The database contains sequence, names, and genome links for P450’s (or Cytochrome P450s) identified by similarity and phylogenetic classification from genome annotations.

Report concludes that a fungal genome database is of “the highest priority”.

This is the title as listed in PubMed for this article from Future Medicine about the AAM report on charting future needs and avenues of research on the fungal kingdom.

The [[Trichoderma reesei]] genome paper was recently published in Nature Biotechnology from Diego Martinez at [[LANL]] with collaborators at [[JGI]], [[LBNL]], and others. This fungus was chosen for sequencing because it was found on canvas tents eating the cotton material suggesting it may be a good candidate for degrading cellulose plant material as part of cellulosic ethanol production.

Tom Bruns, Martin Bidartondo and 250 others sent a letter to Science describing the current problems with fixing annotation in GenBank. There is an entertaining accompanying news article that interviews several people about the problem of updating annotation and species assigned to sequences in the database. In particular the problem for mycologists that many fungi found from metagenomic approaches are only identified through molecular sequences and having the wrong species associated with a sequence can be difficult when studying community ecology composition.  This problem is not limited to fungi by any means, but recent reports find as many as 20% of fungal Intergenic Spacer (ITS) sequences are mis-attributed to the wrong species. 

There’s a nice quote in the news article from Steven Salzberg talking about the difficulties in getting sequences, especially from big centers, updated. I’m sure he is thinking of many examples, like reclassifying some Drosophila sequence traces.

I’ve been too busy to post much these last few days, but here are a few links to some papers I found interesting in my recent browsing.

• FOLy: an integrated database for the classification and functional annotation of fungal oxidoreductases potentially involved in the degradation of lignin and related aromatic compounds – so a database of these enzymes

The UniProtKB/Swiss-Prot team is curating fungal proteins in their databases and reportedly have curated more than 20,000 fungal proteins in Release 54.8 of 05-Feb-2008

Robin reviews recent Nature paper by Ilan Wapinski et al describing the orthogroups they built from multiple fungal genomes. I’ve been remiss in reviewing the paper myself, but they’ve created an important resource in the SYNERGY tool for orthology identification and a database of orthologs of some ascomycete fungi. I am excited there [...]

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.
