Renee Johansen is a P.D. student at the Univ. of Auckland and Landcare Research in Auckland,New Zeand, and is visiting our lab for 8 months on a Fulbright scholarship. Renee is using next-gen sequencing to characterize mycorrhizal fungal communities associated with European marram grass (Ammophila sp.), an invasive species that competes with native dune plants in NZ and in North America.
Here are some links to articles and videos about Renee’s research:

This project addresses taxonomic, genetic and functional diversity of ectomycorrhizal fungi (EMF) associated with Pines across North America. This project will utilize next-generation sequencing techniques, coupled with population genomics, metagenomics, functional enzyme assays and a rigorous ecological sampling design to investigate the diversity of EMF across multiple spatial, genetic and functional scales. Aims of this study are to (1) provide a continental scale perspective on EMF taxonomic diversity associated with pines (2) establish patterns of gene flow and selection for multiple EMF taxa across North America, (3) use hierarchical phylogenetic sampling to measure variation in functional enzyme production across individuals, populations and species of EMF, and (4) use RNA based metagenomics to measure the full spectrum of functional trait expression on individual mycorrhizal root tips. By doing so, this project will synthesize the links among taxonomic, genetic and functional diversity for EMF across dominant pinaceous ecosystems in North America.
