Population structure of Magnaporthe oryzae isolates from green foxtail in Japan examined by DNA fingerprint analysis

| description | The population structure of Magnaporthe oryzae from green foxtail (Setaria viridis) in Japan was examined by DNA fingerprint analyses using the transposable elements MGR586 and MAGGY as probes. Fifteen M. oryzae isolates from green foxtail were collected from 11 Japanese prefectures so that a macrogeographic population of this pathogen is represented. All the 15 isolates were sorted into distinct haplotypes by DNA fingerprint analyses with both probes. Furthermore, similarities between the DNA fingerprint profiles of the 15 isolates were exclusively low; i.e., if lineages are arbitrarily established based on greater than 70% similarities in isolates, the 15 isolates could be categorized into 13 distinct lineages by DNA fingerprinting with both probes. We also examined the MGR586 DNA fingerprint variations of this pathogen in 9 microgeographic populations each of which contained 20 to 24 isolates collected from a 1m2 or 50m2 area. In all the 9 populations, more than 2 haplotypes, which shared less than 70% similarities, were identified in the DNA fingerprint profiles. These results suggested that M. oryzae isolates from the green foxtail in Japan possessed a complex lineage structure, even at the microgeographic scale. |
