Conifer root and butt rot caused by Heterobasidion annosum (Fr.) Bref. s.l.
The root and butt rot caused by Heterobasidon annosum is one of the most destructive diseases of conifers in the northern temperate regions of the world, particularly in Europe and North America. Expand
The Plant Cell Wall–Decomposing Machinery Underlies the Functional Diversity of Forest Fungi
Fungal nutritional mode diversification suggests that the boreal forest biome originated via genetic coevolution of above- and below-ground biota through convergent evolution and divergence among fungal decomposers. Expand
Genome sequencing and population genomic analyses provide insights into the adaptive landscape of silver birch

Variation around the tightly-linked light response genes PHYC and FRS10 correlated with latitude and longitude and temperature, and with precipitation for PHYC, and similar associations characterized the growth-promoting cytokinin response regulator ARR1, and the wood development genes KAK and MED5A.

The molecular factors regulating interspecific interaction between the saprotrophic biocontrol fungus Phlebiopsis gigantea and the conifer pathogen Heterobasidion parviporum were investigated and the potential role of the induced genes during the nonself-competitive interaction for space and nutrients was discussed.

Diversity and Community Structure of Primary Wood-Inhabiting Bacteria in Boreal Forest
DNA-based pyrosequencing analysis of the V1- V3 16S rRNA gene region was used to identify bacteria community and shift during early stages of wood colonization in boreal forest soils, suggesting that variations in soil bacterial community composition have an influence on the wood-inhabiting bacterial structure. Expand
Insight into trade-off between wood decay and parasitism from the genome of a fungal forest pathogen.
It is established that saprotrophic wood decay and necrotrophic parasitism involve two distinct, yet overlapping, processes that show a trade-off in terms of constrained carbohydrate decomposition and membrane transport capacity during interaction with living hosts. Expand
Transcript profiling of a conifer pathosystem: response of Pinus sylvestris root tissues to pathogen (Heterobasidion annosum) invasion.

- 1 October 2007
The similarity of the expression profiling pattern observed in this pathosystem to those documented in crop pathology suggests that angiosperms and gymnosperms use similar genetic programs in responding to invasive growth by microbial pathogens. Expand
Bacterial diversity and community structure along different peat soils in boreal forest
The tree species seems to have more strong impact on the bacterial diversity than the type of peat soil, which drives the changes in bacterial community structure. Expand
Polyporales genomes reveal the genetic architecture underlying tetrapolar and bipolar mating systems
The data are consistent with multiple origins of bipolarity within the Agaricomycetes and Polyporales, although the alternative hypothesis that tetrapolarity and bipolarity are reversible states needs better testing. Expand
Defence related reactions of seedling roots of Norway spruce to infection by Heterobasidion annosum (Fr.) Bref.
Norway spruce seedlings were cultivated in sterile conditions and Roots were infected with a concentration series of germinating conidiospores of Heterobasidion annosu m, causing a greater hypersensitive response than protein fractions but less than NaCl, Polygalacturonic acid or ethephon. Expand
