The spreading of the S type of Heterobasidion annosum from Norway spruce stumps to the subsequent tree stand
TL;DR: In the subsequent stand, the proportion of trees with root rot increased in spruce stands and decreased in stands of other tree species, although silver birch generally was highly resistant to the S type of H. annosum.

TL;DR: In this article, the effects of mixed forests on soil properties, understorey vegetation, biodiversity, wildlife, resistance to and resilience against damage, forest productivity and the multiple use of forests are discussed.

TL;DR: It is shown that the alphapartitivirus HetPV13-an1 affects many basic cellular functions of the white rot wood decay fungus Heterobasidion annosum, which results in aberrant hyphal morphology and a low growth rate.

Two viruses of Heterobasidion confer beneficial, cryptic or detrimental effects to their hosts in different situations
TL;DR: This study shows that a single virus strain confers different effects on different Heterobasidion host strains, and asingle virus strain may have contrasting effects on the fitness of a single host isolate depending on environmental and ecological conditions.

Intersterility groups of Heterobasidion annosum in some spruce and pine stands in Byelorussia, Lithuania and Estonia
TL;DR: Based on its in vitro compatibility with the F group, the S population in Byelorussia and Lithuania is more closely related to the Finnish S population than to the Alpine S population of H. annosum.
