| Abstract: Wheat blast, caused by the Pyricularia oryzae Triticum lineage (PoT), first emerged in Brazil and quickly spread to neighboring countries. Its recent appearance in Bangladesh and Zambia highlights a need to understand the disease's population biology and epidemiology so as to mitigate pandemic outbreaks. Current knowledge is mostly based on characterizations of Brazilian wheat blast isolates and comparison with isolates from non-wheat, endemic grasses. These foregoing studies concluded that the wheat blast population lacks host specificity and, as a result, undergoes extensive gene flow with populations infecting non-wheat hosts. Additionally, based on genetic similarity between wheat blast and isolates infecting Urochloa species, it was proposed... |

| Six Asian Soybean Rust (ASR) resistance loci have been identified and mapped in soybean genome: Rpp1 (Resistance to Phakopsora pachyrhizi 1), Rpp2, Rpp3, Rpp4, Rpp5 and Rpp6. Of particular interest is Rpp4, which has remained stable and confers resistance against Phakopsora pachyrhizi isolates from around the world. Sequencing of the region harboring Rpp4 in the susceptible cultivar Williams 82 (Wm82) and the resistant cultivar (PI459025B) genotype identified a cluster of CC-NBS-LRR resistance genes. Meyers et al. (2009) developed Virus Induced Gene Silencing constructs from the LRR regions of the Wm82 Rpp4 candidate genes to confirm that orthologous genes were responsible for resistance in the resistant parent (PI459025B). In this study, RNA samples... |
