Amplified fragment length polymorphism and sequence analyses reveal massive gene introgression from the European fungal pathogen Heterobasidion annosum into its introduced congener H. irregulare.

Abstract excerpt

The paucity of fungal species known to be currently hybridizing has significantly hindered our understanding of the mechanisms driving gene introgression in these eukaryotic microbes. Here, we describe an area of hybridization and gene introgression between the invasive plant pathogen Heterobasidion irregulare (introduced from North America) and the native H. annosum in Italy. A STRUCTURE analysis of amplified...
