New primers to amplify the fungal ITS2 region – evaluation by 454‐sequencing of artificial and natural communities
Katarina Ihrmark,Inga T. M. Bödeker,Karelyn Cruz-Martinez,Hanna Friberg,Ariana Kubartová,Jessica Schenck,Ylva Strid,Jan Stenlid,Mikael Brandström-Durling,Karina E. Clemmensen,Björn D. Lindahl +10 more
TL;DR: Three new primers are described - fITS7, gITS7 and fITS9 - which may be used to amplify the fungal ITS2 region by targeting sites in the 5.8S encoding gene and yielded more diverse amplicon communities than the ITS1f primer.

Spatial separation of litter decomposition and mycorrhizal nitrogen uptake in a boreal forest
Björn D. Lindahl,Katarina Ihrmark,Johanna Boberg,Susan E. Trumbore,Peter Högberg,Jan Stenlid,Roger D. Finlay +6 more
TL;DR: Observations show that the degrading and nutrient-mobilizing components of the fungal community are spatially separated, which has important implications for biogeochemical studies of boreal forest ecosystems.

TL;DR: 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.
Transmission of double-stranded RNA in Heterobasidion annosum.
TL;DR: Transmission of dsRNA viruses between homo- and heterokaryotic mycelia paired on agar plates and into conidia has been studied in Heterobasidion annosum and identity of nuclei and nuclear migration during experiments were verified using PCR-RFLP of several nuclear markers.

Chemical and transcriptional responses of Norway spruce genotypes with different susceptibility to Heterobasidion spp. infection
Marie Danielsson,Karl Lundén,Malin Elfstrand,Jiang Hu,Tao Zhao,Jenny Arnerup,Katarina Ihrmark,Gunilla Swedjemark,Anna-Karin Borg-Karlson,Jan Stenlid +9 more
TL;DR: The varying dynamics in transcriptional and chemical patterns displayed by the less susceptible genotypes suggest that there is a genotypic variation in successful spruce defence strategies against Heterobasidion, suggesting the importance of the phenolic compounds in the defence.
