Kathie Hodge has a nice description with cool photos of a fungus growing in maple syrup. I guess I better make sure our syrup is in the fridge!

Fungal Genetics 2007 details
Posted on March 28th, 2007 by Jason Stajich · 1 Comment
I'm including a recapping as many of the talks as I remember. There were 6 concurrent sessions each afternoon so you have to miss a lot of talks. The conference was bursting at the seams as it was- at least 140 people had to be turned away beyond the 750 who attended.
If there was any theme in the conference it was "Hey we are all using these genome sequences".

Fungal Genetics 2007 summary

A Fungal Genetics 2007 summary.
Wow. What a meeting! I am still exhausted and not just because of the very late Saturday night dancing at the close of the conference. I will just say anyone who thinks scientists are boring people should witness the passion researchers have for their science and in sharing it with other people.

Hello, do I know you?

Self and non-self recognition is important for fungi when hyphae interact fuse if they should compartmentalize and undergo apoptosis to kill the heterokaryoton or exchange nutrients. This process is part of cell defense and to limit to the movement of mycoviruses.
A paper in PLOS ONE describes the Genesis of Fungal Non-Self Repertoire.

At Asilomar
Posted on March 21st, 2007 by Jason Stajich · 2 Comments
We're at Asilomar mtg for Fungal Genetics 2007. We'll try and blog a bit about the interesting talks and data. I'm curious how many fungal geneticists are in fact reading blogs like these and if this medium will work for idea dissemination.

Genome resources for Candida species
Posted on March 18th, 2007 by Jason Stajich · 1 Comment
The Candida clade of Hemiascomycete fungi have received much attention from funding bodies so that many genomic and experimental resources are available address questions of pathogenecity and industrial applications of these species.
The Candida genus
Traditionally, species of yeasts that were thought to be asexual were given the genus name Candida. This has lead to Candida being a sort of taxonomic rubbish bin.Categories: candida · comparative · phylogeny · saccharomyces
Yeast resequencing data updated
Posted on March 15th, 2007 by Jason Stajich · 3 Comments
The Saccharomyces Genome Resequencing Project has completed " ABI sequencing of 32 S. cerevisiae strains and 27 S. paradoxus strains to a depth of between 1x and 3x". This is in collaboration with Ed Louis' group who have been working on number of really interesting fungal biology.

SGD community annotation
Posted on March 13th, 2007 by Jason Stajich · No Comments
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.

Yeast keeps to itself
Posted on March 7th, 2007 by Jason Stajich · No Comments
Cliff Zeyl and Sally Otto present a nice review on research from the Kruglyak lab regarding evidence that Saccharomyces is primarily a selfer in nature as it outbreeds very infrequently (once in 50,000 generations). The implications of this work has relevance on the importance of sexual reproduction and recombination in natural populations.
