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 that the disease originally emerged via a host jump from this grass and that Urochloa likely plays a central role in wheat blast epidemiology owing to its widespread use as a pasture grass. However, due to inconsistencies with broader phylogenetic studies, we suspected that these seminal studies had not actually sampled the populations normally found on endemic grasses and, instead, had repeatedly isolated members of PoT and the related Lolium pathogen lineage (PoL1). Re-analysis of the Brazilian data as part of a comprehensive, global, phylogenomic dataset that included a small number of South American isolates sampled away from wheat confirmed our suspicion and identified four new P. oryzae lineages on grass hosts. As a result, the conclusions underpinning current understanding in wheat blast's evolution, population biology, and epidemiology are unsubstantiated and could be equivocal. @ This article is in the public domain and not copyrightable.

Uruguay es un país ganadero, productor de carne, exportador, y el crecimiento de su economía depende en gran medida del crecimiento de las exportaciones. Dichos mercados y sus consumidores, se basan en garantías de sólida base científica que certifiquen su calidad. Es así que Uruguay, además de cuidar su status sanitario y su condición de productor de alimentos inocuos, ha debido encarar estudios científicos sobre la calidad de la carne y los procesos en los que ésta se genera, dígase BA, impacto ambiental. Respecto a las estrategias definidas para ello, INIA se encuentra comprometido a jugar un papel fundamental en lo que tiene que ver con generación de tecnologías, priorizando líneas de investigación en Calidad de Producto y Bienestar Animal, coordinando acciones con instituciones de transferencia e innovación de tecnología, universidad, gremiales de productores e industrias de la carne y apostando a la capacitación de sus recursos humanos. |
