Root fungi isolated from common Louisiana marsh plants 2017-18.

Nearly all plants are colonized by fungal endophytes, and a growing body of work shows that both environment and host species shape plant-associated fungal communities. However, few studies place their work in a phylogenetic context to understand endophyte community assembly through an evolutionary lens. Here we collected data to investigate environmental and host effects on root endophyte assemblages in coastal Louisiana marshes. We isolated and sequenced culturable fungal endophytes from roots of three-four dominant plant species from each of three sites of varying salinity. We provide data on abundance and taxonomy of the isolated fungal taxa as well as phylogenetic diversity (mean phylogenetic distance, MPD) and phylogenetic composition (based on MPD).

几乎所有植物都会被真菌内生菌（fungal endophytes）定殖，且越来越多的研究表明，环境与宿主物种共同塑造了植物关联真菌群落的组成。然而，鲜有研究从系统发育视角出发，以进化维度解析内生菌群落的构建机制。本研究通过采集数据，探究环境与宿主对路易斯安那州沿海沼泽植物根系内生菌群落组装的影响。我们从盐度各异的3个采样点中，各选取3至4种优势植物的根系，分离并测序了其中可培养的真菌内生菌。本数据集提供了分离得到的真菌类群的丰度与分类学信息，以及系统发育多样性（平均系统发育距离，mean phylogenetic distance, MPD）和基于MPD的系统发育组成数据。
