The Hyphal Tip

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 [...]
