| phylogenetic and population genetic divergence correspond with habitat for the pathogen colletotrichum cereale and allied taxa across diverse grass communities. | over the past decade, the emergence of anthracnose disease has newly challenged the health of turfgrasses on north american golf courses, resulting in considerable economic loss. the fungus responsible for the outbreaks, colletotrichum cereale, has also been identified from numerous natural grasses and cereal crops, although disease symptoms are generally absent. here we utilize phylogenetic and population genetic analyses to determine the role of ecosystem in the advancement of turfgrass anthra ... | 2009 | 19076279 |
| the evolution of transposon repeat-induced point mutation in the genome of colletotrichum cereale: reconciling sex, recombination and homoplasy in an ''asexual" pathogen. | mobile transposable elements are among the primary drivers of the evolution of eukaryotic genomes. for fungi, repeat-induced point mutation (rip) silencing minimizes deleterious effects of transposons by mutating multicopy dna during meiosis. in this study we identify five transposon species from the mitosporic fungus colletotrichum cereale and report the signature pattern of rip acting in a lineage-specific manner on 21 of 35 unique transposon copies, providing the first evidence for sexual rec ... | 2008 | 17962053 |
