abstract = {Magnaporthe oryzae is a major pathogen of rice (Oryza sativa L.) but is also able to infect other grasses including barley (Hordeum vulgare L.). Here, we report a study using isolates of Magnaporthe collected from other host plant species to evaluate their capacity to infect barley. A non-host type of resistance was detected in barley against isolates derived from Pennisetum (fontaingrass) or Digitaria (crabgrass) but no resistance occurred in response to isolates from rice, Eleusine (goosegrass), wheat (Triticum aestivum L.) or maize (Zea mays L.), respectively. Restriction of pathogen growth in the non-host interaction was investigated microscopically and compared with compatible interactions. Real-time PCR was used to quantify fungal biomass in both types of interaction. The phylogenetic relationship among the Magnaporthe isolates used in this study was investigated by inferring gene trees for fragments of three genes: actin, calmodulin and beta-tubulin. Based on phylogenetic analysis we could distinguish different species which were strictly correlated with the ability of the isolates to infect barley. We demonstrated that investigating specific host interaction phenotypes for a range of pathogen isolates can accurately highlight genetic diversity within a pathogen population.}
