|摘要||The internal tissues of photosynthetic organisms represent one of the most|
extensive and biochemically dynamic habitats on earth. In turn these tissues host
some of the planet’s most ubiquitous and diverse symbionts, endophytic fungi. By
sampling across the green tree of life – from woody angiosperms to the green
algae and cyanobacteria that occur in lichen thalli – we have assembled a global
collection of endophytes that provides a basis for evaluating the factors shaping
this species-rich portion of the ‘global endobiome’ in photosynthetic tissues
across diverse spatial scales, hosts, and ecological communities. Here we use
newly developed phylogenetic- and biodiversity informatics tools to visualize the
relationships of endophytic fungi and ecological metadata in an eco-evolutionary
framework. We discuss the factors shaping endophyte distributions at local,
regional, and landscape scales, and address gaps in knowledge regarding the complementarity of culture-based and next-generation studies; the taxonomic novelty
of fungi obtained in survey efforts, for which only short sequences and/or few to
no morphological characters are available; and the relevance of taxonomic vs.
functional similarity in community structure. Finally we will describe progress
with multilocus- and genomic approaches to interrogate some of the limitations of
current methods for understanding the biogeography of endophytic fungi.
