Mycorrhiza and root-associated fungi of the ericaceous Arctic plant Cassiope tetragona after artificial warming and in the natural environment
Mycorrhizal associations are essential to most plant life on earth. Cassiope tetragona is a circumpolar Arctic plant in the Ericaceae family, which has been reported to form ericoid mycorrhiza as well as ectomycorrhiza, though little is known about the functions and identities of these fungal partne...
