The Hyphal Tip: Fungal Genomes and Comparative Genomics

Hyphoid logic points out that it is appropriate to discuss about the oomycete Phytophthora infestans on St. Patrick's Day and mentions a NYT article "The fungus that conquered Europe" that is worth a look.

It is also worth thinking about another blight, well rust, that is spreading through the middle east and could threaten wheat crops worldwide. New Scientist has excellent coverage of Puccinia

Several more fungi are on the docket for sequencing at JGI through their community sequencing program. This includes

• The Dothideomycete leaf streak disease causing fungus Mycosphaerella fijiensis
• Soybean rust Phakopsora pachyrhizi
• The Basidiomycete and jelly fungus Tremella mesenterica proposed by Joe Heitman for use as outgroup to the human pathogen Cryptococcus
• The plant pathogen Cochliobolus heterostrophus proposed by Gillian Turgeon which ironically was already sequenced

A while back, Jason blogged briefly on a New Scientists article about the rise of a new Puccinia graminis strain, Ug99, that is spreading through West African wheat fields at an enormous rates. It looks like this story is growing in the scientific conciousness, as Science is now running an article on the spread of this wheat pandemic.

The New Scientist has an article about the spread of black stem rust caused by Puccinia graminis. We briefly mentioned the 1st release of a Puccinia genome in January. Some more links about the spread of the Ug99 virulent strain.

• SeedQuest
• USDA information
• USDA information on Barberry & Puccinia graminis where the sexual stage of the fungus occurs.

The 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 sequenced.
