Arbuscular mycorrhizal (AM) and dark septate endophytic (DSE) fungi are rarely studied at extremely high elevations. Here, AM and DSE colonization in two dominant plant species (Melandrium apetalum and Poa litwinowiana) were microscopically observed on the forefront of Zhadang Glacier (5,500 m above sea level) in the Qinghai-Tibet Plateau, China. The AM fungal taxa were also identified by molecular methods. Both AM and DSE fungi synchronously colonized these two plant species, but AM dominated in M. apetalum and DSE dominated in P. litwinowiana. A total of five AM fungal spore morphotypes (Acaulospora capsicula, Diversispora sp., Glomus constrictum, G. eburneum and Glomus sp.) were found in the rhizosphere soils. Molecular identification revealed two AM fungal phylotypes: one Claroideoglomus phylotype from roots and one Diversispora phylotype from spores. These results extend the elevation at which both AM and DSE are known to occur. |
