An article in PLoS Pathogens by Morris et al describe a hypothesis about the evolution and origins of plant pathogens applying the parallel theories to the emergence of medically relevant pathogens. The authors highlight the importance of understanding the evolution of organisms in the context of emerging pathogens like Puccinia Ug99 for our ability [...]

The Tremella mesenterica genome portal is live on the JGI site. Tremella is a Basidiomycete jelly fungus and an interesting study system from the perspective of discovery of novel lignin degrading enzymes. It also occupies an interesting phylogenetic position being an outgroup to the human pathogenic yeast Cryptococcus neoformans and C. [...] An avid reader pointed out that I was not entirely thorough in describing that we don’t enough about the V8 agar media that is used to induce mating in Cryptococcus. In fact a great deal of work on mating in this fungus had focused on identifying what pathways are induced by V8 agar that [...] A paper in IJSEM describes a new species in the Cryptococcus basidiomycete yeast lineage. The name is proposed as Cryptococcus keelungensis sp. nov. for a strain isolated from the sea surface microlayer. Its identity as a Cryptococcus sp was determined by sequencing of 26S rDNA D1/D2 and ITS loci and molecular phylogenetics. This is quite diverged from the human pathogen Cryptococcus neoformans and C. gattii as the new species falls in the order Filobasidiales while C. neoformans is classified in the order Tremellales. Interestingly, based on the phylogeny in the paper it seems to be relatively close to newly discovered Cryptococcus [...] 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 [...] The Scientist has an article about airborne opportunistic fungal infections and interviewing several Cryptococcus researchers including Karen Bartlett and James Fraser. NPR’s Science Friday covered fungi with several myco-luminaries on the [...] An outbreak of a fungal infection called “white-nose syndrome” is killing bats in the Northeastern US. This New Scientist article mentions the outbreak briefly and an NPR story and recent Boston Globe story also gives it some [...]
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.
