| development of genomic ssr markers and molecular characterization of magnaporthe oryzae isolates from wheat in brazil. | magnaporthe oryzae, the causal agent of wheat blast, was characterized on a molecular level with 38 newly isolated genomic ssr loci. among the 31 wheat isolates analyzed, 15 polymorphic loci were detected, with an average of 1.7 alleles per locus, 28.9% of them being highly or reasonably informative. the number of polymorphic loci was higher in isolates from londrina in the brazilian state of paraná and coromandel in minas gerais compared with goiânia in goiás and são borja in rio grande do sul. ... | 2014 | 24271825 |
| population structure and pathotype diversity of the wheat blast pathogen magnaporthe oryzae 25 years after its emergence in brazil. | since its first report in brazil in 1985, wheat blast, caused by magnaporthe oryzae (anamorph: pyricularia oryzae), has become increasingly important in south america, where the disease is still spreading. we used 11 microsatellite loci to elucidate the population structure of the wheat blast pathogen in wheat fields in central-western, southeastern, and southern brazil. no subdivision was found among the wheat-infecting populations, consistent with high levels of gene flow across a large spatia ... | 2014 | 23901831 |
