Project name: uncultured fungus

Description: The aim of this study was to identify the aerial endomycobiota associated with Abies balsamea branches and to compare its diversity and composition as a function of tissue type at a regional scale. Based on 256 samples from 16 healthy looking individuals of balsam fir trees collected at 2 locations within the Forêt Montmorency research forest north of Quebec City, we first show that the diversity of the endomycobiota differs as a function of tissue type. Communities associated with needle and wood were more diverse than bud and bark communities. Then, we demonstrate that the different tissue types displayed distinct communities which impaired the definition of a precise core community shared by all tissue types. We thus advocate refining the scope of resolution to the tissue type level for a better understanding of the interactions between the plant and its associated microorganisms. Together, our results suggest that the aerial endomycobiota of balsam fir trees might be fractioned in distinct communities depending on the tissue types.
