18S rRNA gene amplicon of the arbuscular mycorrhizal fungi associated with the roots of the fern Botrychium lunaria in the Swiss Alps
The primers AMV4.5NF (5-AAGCTCGTAGTTGAATTTGC-3) and AMDGR (5-CCCAACTATCCCTATTAATCAT-3) (Sato et al., 2005) were used to amplify a fragment of the 18S rRNA gene including the variable domain V4.
