| Abstract/Contents: | "Pyricularia grisea isolates from perennial ryegrass were compared with strains from several gramineous hosts using a number of molecular markers including MGR586, mating type genes, a host specificity gene (PWL2), ITS sequence of genes encoding ribosomal RNA and Pot2. The ryegrass isolates contained only a few copies of MGR586, indicating that they are distinct from rice pathogens. These isolates belonged to the same mating group (Mat1-2). Not all ryegrass isolates contained the PWL2 gene. ITS of the ryegrass isolates was amplified and sequenced. The sequence was identical among the ryegrass isolates and showed highest similarity to those from Eleusine and Triticum species. DNA fingerprinting using Pot2 showed that the ryegrass isolates exhibited no significant variation (87-97% identity) among themselves and showed limited similarity to isolates of P. grisea from Triticum species. In a pathogenicity study, seven of the eight ryegrass isolates caused disease symptoms on hard red winter wheat, soft white winter wheat or triticales. Both molecular and pathogenicity data suggest that isolates of P. grisea from wheat and ryegrass are related." |
