pattern and molecular diversity of arbuscular mycorrhizal fungi from floating islands in Hungary. – Sydowia 72: 131–148.
Floating islands are pseudo-dry lands composed by littoral macrophyte vegetation bending down on water and forming interwoven
rhizomes and roots collecting debris and litter, which may be followed by a succession of herbal and woody species.
Arbuscular mycorrhizal (AM) symbiosis of characteristic plant species from the rooting layers of three species-poor floating islands
with distinct trophity in Hungary were studied. According to our knowledge, colonization of 25 plant species was shown
for the first time in a wetland/floating island ecosystem. As a first report of AM fungal molecular diversity on floating islands 15
phylotypes belonging to Glomeraceae, Entrophosporaceae and Acaulosporaceae were characterized. Results confirm that certain
AM fungal taxa may have a preference of wetlands although specific taxa characteristic to floating islands have not been shown.
