What is it about?
The couch grass grew in the proximity of Scots pine that was visibly affected by the pathogen. The pathogenic fungus Heterobasidion annosum was identified in the rhizome of a couch grass (Elymus repens) using genetic markers.

Why is it important?
Our findings suggest that the known modes of infection of tree roots by the pathogen Heterobasidion annosum in coniferous stands should take into account couch grass rhizomes as a vector of the disease in afforested post-agricultural soils.
Perspectives
The rDNA analysis showed 100% sequence similarity between two H. annosum core-sequences of ITS1 and ITS2 obtained from fruiting bodies found on the couch grass rhizome and on the stem of the Scots pine.
