Project summary


My project focus on the biodiversity and the patterns of distribution of the endophyte fungi within balsam fir trees (Abies balsamea) in boreal forest (Forêt Montmorency ). I use a metabarcoding approach on ITS fragment (=Internal Transcribed Spacer, a nuclear rDNA fragment which was recently defined as the official fungal barcode, but used since the 1990s) with parallel/second-generation sequencing (454 Roche pyrosequencing) and occasionally Petri cultures. I am more looking at local variations within trees than a geographical scale.

Research Affiliate at Natural Resources Canada (September 2010 - September 2015)

Worked on the transition from cloning technics to parallel/second-generation sequencing (454 Roche pyrosequencing) to access endophytic fungal biodiversity on boreal forest trees (metabarcoding on ITS fragment from environmental samples); defining laboratory protocols and bioinformatical treatment of the data. The concern was to elaborate a reference native endophytic fungal database to identify exotic fungi in imported plant material in Canada and evaluate their potential as pathogenic agent.
