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 [...]

A link to the story about Matteo Garbelotto’s work on Phytophthora ramorum and showing that the source in California is likely from ornamentals from a nursery. The work is to appear soon in Molecular Ecology but alas is not available yet. A recent paper on updated Phytophthora phylogeny from Jamie Blair and co-authors is also out in FGB. [...] DuPont/Pioneer Hi-Bred has donated the genome sequence of the Sordariomycete Colletotrichum graminicola into the public domain by depositing the sequence in GenBank. The FGI through the Broad Institute are also sequencing a strain of C. graminicola (teleomorph Glomerella [...] The JGI have released the genome sequence and annotation of the Mycosphaerella fijiensis fungus an important crop pathogen of bananas. This Dothideomycete fungus is one of several in the clade of important plant pathogens that have been sequenced recently including M. gramicola, a relative that causes wheat-blotch.
Several more fungi are on the docket for sequencing at JGI through their community sequencing program. This includes
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 [...] 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.
I’ve never worked with Magnaporthe grisea, the fungus responsible for rice blast, one of the most devastating crop diseases, but I do know that its life cycle is complicated and that knocking out roughly 61% of the genes in the genome and evaluating the mutant phenotype to infer gene function is not trivial. In their recent letter to Nature, Jeon et al did what [...] |
