The C is for Catalog

It seems intuitive enough that the size of an organism’s genome should be related to its evolutionary complexity. As a general rule, this tends to be true. But look within a class of organisms and you’ll find a great deal of genome size – also known as a C-value – variation. A [...]

Experimental cooperative evolution

A paper in Nature this week describes how a few mutations can alter the interactions between species in a biofilm from competitive to cooperative system. This is a great study that goes from start to finish on studying community interactions, looking at an evolved phenotype, and understanding the genetic and physiological basis for the [...]

Jason Stajich maintains this blog site, a wiki for collaboration, and software and is an Assistant Professor University of California, Riverside in the Department of Plant Pathology and Microbiology and Institute for Integrative Genome Biology.  He also provides some genome browsers for fungal genomes as part of his research [...]

Making the Revolution Work for You

In a recent Microbiology Mini-Review, Meriel Jones catalogs both the potential benefits and problems that arise from fungal genome sequencing. [...]

Not one, but two Aspergillus niger genome sequences

Blogging about Peer-Reviewed ResearchA.niger growing on plate (this is not the sequenced strain)The JGI has previously released A.niger strain ATCC 1015 sequence in November 2005. [...]

Genomes of honeybee pathogens

The Baylor sequencing center has published the genome of two honey bee pathogens. Bayolor and collaborators recently published a slew of honey bee genome papers and it is great that they have also chosen to follow up on the parasites as [...]

Tripartate symbioses with fungi

Ants, fungi, and bacteria
I have to admit that I am fascinated by co-evolution of symbiotic and mutalistic systems. A review by Richard Robinson gives an overview. A great example is the mutalism between ants and fungi where the ants cultivate the fungi for food. [...]

All hail the rusts

pucciniaThe FGI and the Broad Institute have released the 7X genome assembly of Puccinia graminis f. sp tritici in roughly 4500 contigs. This represents the first rust fungus to be [...]

Diploidy inevitable for yeast?

Sally Otto and colleagues have identified that populations of laboratory yeast strains convereged onyeast diploidy in this study. This is nicely consistent with the observation that most wild strains isolated from the environment are [...]

Glomales repetitive elements

A recent paper identifies “Twenty-five repetitive elements … in the genomes of the arbuscular mycorrhizal (AM) fungi Gigaspora margarita, Gig. rosea and Glomus [...]
