Resurgence of Less-Studied Smut Fungi as Models of Phytopathogenesis in the Omics Age.

abstract：:The phytopathogen Phytophthora cactorum infects economically important herbaceous and woody plant species. P. cactorum isolates differ in host specificity; for example, strawberry crown rot is often caused by a specialized pathotype. Here we compared the transcriptomes of two P. cactorum isolates that differ in their ...
