| phylogenetic relationships, host affinity, and geographic structure of boreal and arctic endophytes from three major plant lineages. | although associated with all plants, fungal endophytes (microfungi that live within healthy plant tissues) represent an unknown proportion of fungal diversity. while there is a growing appreciation of their ecological importance and human uses, little is known about their host specificity, geographic structure, or phylogenetic relationships. we surveyed endophytic ascomycota from healthy photosynthetic tissues of three plant species (huperzia selago, picea mariana, and dryas integrifolia, repres ... | 2007 | 17005421 |
