Agricultural ecosystems are composed of genetically depauperate populations of crop
plants grown at a high density and over large spatial scales, with the regional composition of …

Alternaria alternata is a common species of fungus frequently isolated from plants as both an
endophyte and a pathogen. Although the current definition of A. alternata rests on a …

Wheat, one of the most important food crops, is threatened by a blast disease pandemic.
Here, we show that a clonal lineage of the wheat blast fungus recently spread to Asia and …

Understanding the origins of variation in agricultural pathogens is of fundamental interest
and practical importance, especially for diseases that threaten food security. Fusarium …

Many species of fungal plant pathogens coexist as multiple lineages on the same host, but
the factors underlying the origin and maintenance of population structure remain largely …

Fungi are a diverse group of organisms with a huge variation in reproductive strategy. While
almost all species can reproduce sexually, many reproduce asexually most of the time …

Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …
