Ireland’s blight and Puccinia update

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

Puccinia black stem rust disease spreading

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.

Origins and evolution of pathogens

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 to … Continue reading Origins and evolution of pathogens

Fungal tree of life papers

Lots of papers in Mycologia (subscription required) this month of different groups analyzing the fine-scale relationships of many different fungal clades using the loads of sequences that were generated as part of the Fungal Tree of Life project.
