dc.description.abstract | Fungal diversity and composition are still relatively unknown in many ecosystems; however, host
identity and environmental conditions are hypothesized to influence fungal community assembly. To
test these hypotheses we characterized the richness, diversity, and composition of rhizosphere fungi
colonizing three alpine plant species, Taraxacum ceratophorum, Taraxacum officinale, and Polemonium
viscosum. Roots were collected from open meadow and willow understory habitats at treeline on
Pennsylvania Mountain, Colorado, USA. Fungal small subunit ribosomal DNA was sequenced using
fungal-specific primers, sample-specific DNA tags, and 454 pyrosequencing. We classified operational
taxonomic units (OTUs) as arbuscular mycorrhizal (AMF) or non-arbuscular mycorrhizal (non-AMF) fungi,
then tested whether habitat or host identity influenced these fungal communities. Approximately 14%
of the sequences represented AMF taxa (44 OTUs) with the majority belonging to Glomus group A and B.
NON-AMF sequences represented 186 OTUs belonging to Ascomycota (58%), Basidiomycota (26%),
Zygomycota (14%), and Chytridiomycota (2%) phyla. Total AMF and non-AMF richness were similar
between habitats, but varied among host species. AMF richness and diversity per root sample also
varied among host species and were highest in T. ceratophorum compared to T. officinale and P.
viscosum. In contrast, non-AMF richness and diversity per root sample were similar among host species
except in the willow understory where diversity was reduced in T. officinale. Fungal community
composition was influenced by host identity, but not habitat. Specifically, T. officinale hosted a different
AMF community than T. ceratophorum and P. viscosum, while P. viscosum hosted a different non-AMF
community than T. ceratophorum and T. officinale. Our results suggest that host identity has a stronger
effect on rhizosphere fungi than habitat. Furthermore, although host identity influenced both AMF and
non-AMF this effect was stronger for the mutualistic AMF community. | |
