Comparative genomic analysis of phytopathogenic fungi using expressed sequence tag (EST) collections
SUMMARY We describe the analysis of 57 727 unique expressed sequence tags (ESTs) from 15 species of phytopathogenic and three species of saprophytic fungi. This resource is held within the COGEME phytopathogen EST database (http://cogeme.ex.ac.uk/). Comparative analysis was performed to investigate the differences between pathogenic and free-living fungi based on a substantial collection of expressed gene sequences and available, completed fungal genome sequences. We report that the expressed gene inventories of pathogenic fungi were not significantly more similar to each other than to those of free-living filamentous fungi. As expected, however, filamentous fungi as a group share more sequences in common than with the free-living yeast species Saccharomyces cerevisiae. Interestingly, ESTs of the obligate biotrophic fungus Blumeria graminis f. sp. hordei were more dissimilar to those of all other fungal species assessed, having a lower number of sequences in common with filamentous ascomycetes studied to date and also possessing a larger proportion of unisequences of unknown function. Our analysis of ESTs in the COGEME database enabled identification of a set of functional groups of genes that are more highly represented in the genomes of pathogenic fungi than non-pathogenic species.
