Host genotype shapes the foliar fungal microbiome of balsam poplar (Populus balsamifera).

Foliar fungal communities of plants are diverse and ubiquitous. In grasses endophytes may increase host fitness; in trees, their ecological roles are poorly understood. We investigated whether the genotype of the host tree influences community structure of foliar fungi. We sampled leaves from genoty...
