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 …

The study of plant diseases is almost as old as agriculture itself. Advancements in molecular
biology have given us much more insight into the plant immune system and how it detects …

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 …

Most plant pathogens exhibit host specificity but when former barriers to infection break
down, new diseases can rapidly emerge. For a number of fungal diseases, there is …

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 …

Historical trajectories of tree species during the late Quaternary have been well
reconstructed through genetic and palaeobotanical studies. However, many congeneric tree …
