迄今为止，世界范围内约1000种温带树种中约有10%已被调查真菌内生菌的发生。观察到的多样性，主要以栽培菌株的物种丰富度来衡量，范围从几个分类群到每个树种超过100个物种。然而，统计物种丰富度和分子系统发育分析表明，观察到的物种数量只是宿主植物有效内生菌丰富度的一小部分，生物组织的相关单位可能低于物种水平，在种群和种型水平上。最先进的高通量技术，如稀释至灭绝培养和目标DNA位点的大规模平行测序，可以克服迄今为止阻碍详尽调查的限制。生物多样性的其他方面，如寄主偏好和物种在不同基质、地理区域或采集时间上的更替，很少得到解决，但将揭示温带森林内生植物生物和功能多样性的新模式。此外，将经典生态学理论应用于植物内生生理学将会带来该领域的实质性进展。
Approximately 10% of around 1,000 temperate tree species have so far been investigated for the occurrence of fungal endophytes, world-wide. The observed diversity, mostly measured as species richness of cultivated strains, ranges from a few taxa to more than 100 species per tree species. Statistical species richness and molecular phylogeny analyses indicate however, that the observed species numbers are only a fraction of the effective endophyte richness of a host plant, and that the relevant unit of biological organisation may lie below the species level, at the level of populations and phylotypes. State-of-the-art high-throughput techniques such as dilution-to-extinction cultivation and massively parallel sequencing of target DNA loci could overcome the limits that have prevented exhaustive surveys so far. Further aspects of biodiversity, such as host preference and species turnover on different substrata, geographical regions, or collection times have rarely been addressed, but would reveal new patterns of biological and functional diversity of temperate forest endophytes. Furthermore, application of classical ecological theory to endophytology could lead to substantial progress in the field.
