(Submitter supplied) Members of the fungal genus Armillaria are necrotrophic pathogens with efficient plant biomass-degrading strategies. Armillaria species are some of the largest terrestrial organisms on Earth that cause tremendous losses in diverse ecosystems. Despite their global importance, how Armillaria evolved pathogenicity in a clade of dominantly non-pathogenic wood-degraders (Agaricales) remains elusive. Here, using new genomic data, we show that Armillaria species, in addition to widespread gene duplications and de novo gene origins, appear to have acquired at least 1025 genes via 124 horizontal gene transfer (HGT) events, primarily from Ascomycota donors. more...

(Submitter supplied) The genus Armillaria spp. (Fungi, Basidiomycota) includes devastating pathogens of temperate forests and saprotrophs that decay wood. Pathogenic and saprotrophic Armillaria species can efficiently colonize and decay woody substrates, however, mechanisms of wood penetration and colonization are poorly known. We assayed the colonization and decay of autoclaved spruce roots using the conifer-specialists Armillaria ostoyae and A. more...

(Submitter supplied) Armillaria species are devastating forest pathogens that are among the largest terrestrial organisms on Earth. They explore hosts and achieve immense colony sizes by rhizomorphs, root-like multicellular structures of clonal dispersal. To resolve the genetic bases of their unique biology, we sequenced and analyzed genomes of 4 Armillaria species and performed RNA-Seq on 7 invasive and reproductive developmental stages. more...
