Seasonal dynamics of fungal communities associated in soils in a Panicum virgatum Mississippi common garden experiment

Switchgrass (Panicum virgatum L.) is used in conservation agriculture because of its broad geographical distribution and its potential high yields on marginal or low-productivity agricultural lands. We sampled fungi inhibiting roots of four switchgrass cultivars planted at low and high in southeastern Mississippi and MiSeq-analyzed fungal (Internal Transcribed Spacer 2 (ITS2) of the ribosomal RNA repeat) metabarcode markers to evaluate fungal community seasonal dynamics as well as to analyze community responses to switchgrass cultivars and planting densities. These data contribute towards a better understanding of interactions among plants and their associated microbiomes as well as their seasonal dynamics.柳枝稷（Switchgrass，*Panicum virgatum* L.）因具有广泛的地理分布，且在边际或低产农田上具备潜在的高产能，被应用于保护性农业。本研究采集了种植于密西西比州东南部、分别以低密度和高密度栽培的4个柳枝稷品种的根系真菌，通过MiSeq测序技术对真菌代谢条形码标记——核糖体RNA重复序列的内转录间隔区2（ITS2）进行分析，以评估真菌群落的季节动态，并解析真菌群落对柳枝稷栽培品种及种植密度的响应。本数据集有助于深化对植物与其相关微生物组之间的互作关系及其季节动态的认知。
