Seasonal dynamics of bacterial communities in soils underneath Panicum virgatum in a Mississippi common garden experiment

Switchgrass (Panicum virgatum L.) is a conservation agriculture crop with broad geographical distribution and high potential yields on marginal agricultural lands. We sampled bacteria in soils under four switchgrass cultivars planted at low and high densities in southeastern Mississippi and MiSeq-analyzed bacterial metabarcode (hyperveriable V4 region of the 16S ribosomal rna gene) markers to evaluate bacterial 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.

紫花茅草（ Panicum virgatum L.）作为一种具有广泛地理分布和在高产潜力的边际农业土地上得以推广的保育型农业作物，本研究对其土壤中的细菌进行了采样。采样地点位于密西西比州东南部，种植了四种不同品种的紫花茅草，且种植密度分为低密度和高密度。通过 MiSeq 测序技术对细菌的宏条形码（16S 核糖体RNA基因的可变V4区域）进行测序分析，旨在评估细菌群落随季节的变化动态，以及分析群落对紫花茅草品种和种植密度的响应。这些数据有助于深入理解植物与其相关微生物组之间的相互作用及其季节性动态。
