ABSTRACT Delineating species and epidemic lineages in fungal plant pathogens is critical to our understanding of disease emergence and the structure of fungal biodiversity and also informs international regulatory decisions. Pyricularia oryzae (syn. Magnaporthe oryzae ) is a multihost pathogen that ...

Wheat blast caused by Magnaporthe oryzae pathotype Triticum (MoT) is a threat to wheat production especially in the warmer-humid environments. In Zambia, wheat blast symptoms were observed for the first time on wheat (Triticum aestivum L.) grown in experimental plots and five farmers' fields in Mpik...

Wheat blast has emerged as a major threat to wheat production in South America. Although originally restricted to Brazil, the disease has since been observed in the neighboring countries of Argentina, Bolivia, and Paraguay and recently the pathogen, Magnaporthe oryzae Triticum pathotype, was isolate...

Wheat head blast (WHB), caused by the fungus Magnaporthe oryzae pathotype triticum, is a devastating disease affecting South America and South Asia. Despite 30 years of intensive effort, the 2N V S translocation from Aegilops ventricosa contains the only useful source of resistance to WHB effective ...

Wheat blast is an explosive new fungal disease of wheat caused by an Magnaporthe oryzae (synonym of Pyricularia oryzae) host-adapted subpopulation, the M. oryzae Triticum pathotype (MoT). MoT has been found in South America, South Asia, and Africa, but not in the United States. Wheat blast caused by...

The fungal pathogen, Magnaporthe oryzae Triticum pathotype, causing wheat blast disease was first identified in South America and recently spread across continents to South Asia and Africa. Here, we studied the genetic relationship among isolates found on the three continents. Magnaporthe oryzae str...

ABSTRACT Global wheat production is seriously threatened by the filamentous fungal pathogen, Magnaporthe oryzae , causing wheat blast disease. The pathogen was first identified in South America and recently spread across continents to Bangladesh (South Asia) and Zambia (South-central Africa). M. ory...

This is a response to a recent Letter to the Editor of Phytopathology, in which Gupta et al. (2019) caution against the indiscriminate use of the MoT3 diagnostic assay that distinguishes isolates of Magnaporthe oryzae in the Triticum lineage from those that do not cause aggressive wheat blast. We co...

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 outbr...

Wheat blast, caused by the Triticum pathotype of Pyricularia oryzae, is an emerging disease that threatens the global supply of wheat. The pathogen was first reported in Brazil and subsequently spread to the neighboring countries of Argentina, Bolivia, and Paraguay. More recently, wheat blast was re...
