Fungal endophytes: cryptic keys to understanding the evolution of major ecological modes in the Ascomycota.
In the last five years, tremendous progress in inferring the fungal tree of life has provided new insight into broad patterns underlying the evolution of plant-fungal symbioses. A major missing piece, however, remains in the poorly known and cryptic microfungi, such as endophytes associated with healthy foliage, which are not yet routinely incorporated into multilocus phylogenies. I will highlight the tremendous diversity, variable host specificity, and diverse evolutionary history of endophytic fungi (1) associated with all major lineages of land plants and (2) at sites ranging from the tropics to the tundra. Using multi-gene phylogenies as a foundation, I will show that these often overlooked fungi are key to understanding the shape and content of the fungal tree of life, and that they provide a critical ‘missing piece’ for understanding the evolution of major ecological modes in the Ascomycota, the most species-rich fungal phylum.
