Silver birch (Betula pendula) is a pioneer boreal tree that can be induced to flower within 1 year. Its rapid life cycle, small (440-Mb) genome, and advanced germplasm resources make an attractive model for forest biotechnology. We assembled chromosomally anchored the nuclear genome of inbred B. pendula individual. Gene duplicates from paleohexaploid event were enriched transcriptional regulation, whereas tandem overrepresented by environmental responses. Population resequencing 80...
Summary Tree bark is a highly specialized array of tissues that plays important roles in plant protection and development. Bark develop from two lateral meristems; the phellogen (cork cambium) produces outermost stem–environment barrier called periderm, while vascular cambium contributes with phloem tissues. Although diverse terms tissues, functions species, it remains understudied at higher resolution. We dissected stem silver birch ( Betula pendula ) into eight major tissue types,...
High levels of phenotypic variation in resistance appears to be nearly ubiquitous across natural host populations. Molecular processes contributing this nature are still poorly known, although theory predicts evolve at specific loci driven by pathogen-imposed selection. Nucleotide-binding leucine-rich repeat (NLR) genes play an important role pathogen recognition, downstream defense responses and signaling. Identifying the NLRs has potential increase our understanding how NLR diversity is...
In the version of this article initially published, there was a mistake in calculation nucleotide mutation rate per site generation: 1 × 10−9 mutations generation used, whereas 9.5 correct. This error affects interpretation population-size changes over time and their possible correspondence with known geological events, as shown original Fig. 4 supporting discussion text, well details Supplementary Note. Neither data themselves nor any other results are affected. Figure has been revised...

Abstract Integration of community ecology with disease biology is viewed as a promising avenue for uncovering determinants pathogen diversity, and predicting risks. Plant-infecting viruses represent vastly underestimated component biodiversity potentially important ecological evolutionary roles. We performed hierarchal spatial analysis wild plant populations to characterise the diversity coexistence structure within-host virus communities, their predictors. Our results show that these...
Abstract Inonotus obliquus , Chaga mushroom, is a fungal species from Hymenochaetaceae family ( Basidiomycota ) which has been widely used for traditional medicine in Europe and Asia. Here, chaga genome was sequenced using Pacbio sequencing into 50.7Mbp assembly consisting of 301 primary contigs with an N50 value 375 kbp. Genome evolution analyses revealed lineage-specific whole duplication event expansion Cytochrome P450 superfamily. Fungal biosynthetic clusters were enriched tandemly...
