Article Synopsis
- The Myxogastria are soil microorganisms with a unique life cycle that includes a visible fruiting stage and were previously classified based on physical traits.
- This study is the first to analyze their phylogenetic relationships using molecular data, focusing on ribosomal RNA and elongation factor gene sequences from various species.
- Findings indicate three distinct groups within Myxogastria, with spore pigmentation serving as a key characteristic for classification, suggesting that simple forms in some species are not necessarily primitive.
• The knowledge of temporal and spatial structure of populations of ectomycorrhizal fungi, together with the origin and maintenance of their genetic variation, is critical to understanding how populations of these fungi establish, evolve and disappear at different stages of development of forest ecosystems. • Identification and spatial delimitation of genets in populations of the ectomycorrhizal basidiomycetes, Laccaria amethystina, Xerocomus chrysenteron and X. pruinatus were inferred from the polymorphism of two codominant genetic loci, the nuclear rDNA internal transcribed spacers (ITS) and intergenic spacers (IGS), and anonymous dominant RAPD markers from basidiocarps collected in a mixed mature forest in the fungal reserve of La Chanéaz (Switzerland).
