The Magnaporthe comparative genomics database provides accesses to multiple fungal genomes from the Magnaporthaceae family to facilitate the comparative analysis. As part of the Broad Fungal Genome Initiative, the Magnaporthe comparative project includes the finished M. oryzae (formerly M. grisea) genome, as well as the draft assemblies of Gaeumannomyces graminis var. tritici and M. poae, all funded by joined efforts of NSF and USDA through NSF/USDA Microbial Genome Sequencing Program.
The Magnaporthe comparative project is a partnership between the International Rice Blast Genome Consortium, and the Broad Institute. The project is facilitated by an Advisory Board made up of members of the Rice Blast research community, including:
Ralph Dean (head) - NC State University.
Bruce Birren - Broad Institute
Daniel Ebbole - Texas A&M University
Mark Farman - University of Kentucky
Linda Kohn - Department of Biology University of Toronto

M. poae produces sexual structures (perithecia, asci and ascospores) that clearly place it with Magnaporthe. However, unlike other Magnaporthe species such as M. salvinii, M. grisea and M. oryzae, which have Pyricularia anamorphs (forms that produce asexual spores) bearing spores sympodially on conidiophores, the M. poae anamorph has Phialophora like spores borne on phialides, in much the same manner as Gaeumannomyces. As such, M. poae, along with M. rhizophila, seems to represent a phylogenetic bridge between the Magnaporthe: Pyricularia and Gaeumannomyces:Phialophora groups (Figure 1).
