Abstract below:
All plants, including those in cultivated and managed settings, host diverse fungal symbionts called endophytes in their healthy photosynthetic tissue. While plant genotype is often linked with endophytic community structure in agroecosystems, it is becoming increasingly evident that community assembly and function are context-dependent and change across species and ecological scales. We sampled Torreya taxifolia saplings at a conservation nursery in Durham, North Carolina to characterize foliar endophytic fungi for this species the first time, and link variation in endophyte communities to host genotype and to the nursery setting. We found all trees to be healthy and pathogen-free, each harboring distinct endophytic fungal communities that are structured spatially based on proximity to a forest edge. We saw class-level differences in fungal taxa between two sampling years, indicating that young saplings may be experiencing successional dynamics in their endophyte communities after 7 years in-ground. Overall, our results show that fine-scale environmental variation is a strong influence on endophyte communities, that T. taxifolia possesses a high capacity for establishing symbioses with fungi outside of its native range, and that understanding these symbioses has the potential to inform cultivation practices in host taxa that are rare or threatened.
