A single nucleotide polymorphism genotyping panel for efficient genetic stock identification of the Teno river Atlantic salmon (Salmo salar) population complex

Journal of Fish Biology, EarlyView.
Abstract A new single nucleotide polymorphism (SNP) panel for genetic stock identification in the Teno river Atlantic salmon, Salmo salar L., fishery was developed, with a view to improving on an existing microsatellite panel. Twenty‐two genetically differentiated reporting units were proposed based on population genetic analyses of 1212 individuals ...

Endophytic and ectomycorrhizal, an overlooked dual ecological niche? Insights from natural environments and Russula species

New Phytologist, EarlyView.
Summary Ectomycorrhizal fungi (EcMF) are key components of temperate ecosystems, and recent studies suggest that they can also inhabit non‐EcM plant roots as endophytes. We aimed to (1) provide new evidence of EcMF colonization of non‐EcM hosts, (2) offer direct microscopic confirmation of such endophytism and (3) assess factors influencing ...
