Taxonomic affinities of dark septate root endophytes of Colobanthus quitensis and Deschampsia antarctica, the two native Antarctic vascular plant species
Although dark septate fungal endophytes (DSE) occur widely in association with plant roots in cold-stressed habitats, little is known of the taxonomic status of DSE in Antarctica. Here we investigate the phylogenetic affinities of DSE colonising the roots of Colobanthus quitensis and Deschampsia ant...
