Foliar endophyte diversity in eastern Asia-eastern North America disjunct tree species – Influences of host identity, environment, phylogeny, and geographic isolation

The well-known eastern Asia (EA) and eastern North America (ENA) floristic disjunction provides a unique system for biogeographic and evolutionary studies. Despite considerable interest in the disjunction, few studies have investigated the patterns and their underlying drivers of allopatric divergence in sister species or clades isolated in the two areas. Endophyte diversity and assembly in disjunct sister taxa, as an ecological trait, may have played an important role in the processes of allopatric evolution, but no studies have examined endophytes in these disjunct lineages. In this study, we compared foliar endophytes (including both fungi and bacteria) in 17 EA-ENA disjunct species pairs from genera representing conifers and major clades of angiosperms, as well as 23 species of Cornus from the US and China. We sequenced the ITS of fungi and 16S rDNA of bacteria to understand the composition of the endophyte community and gain insights into the relative roles of geographic isolation,..., , , # Foliar Endophyte Diversity in Eastern Asia-Eastern North America Disjunct Tree Species Influences of Host Identity, Environment, Phylogeny, and Geographic Isolation
