Symbioses are unique habitats for bacteria. We surveyed the spatial diversity of bacterial communities across multiple individuals of closely related lichens using terminal restriction fragment length polymorphism (T-RFLP) and pyrosequencing. Centers of lichens house richer, more consistent assemblages than species-poor and compositionally disparate lichen edges, suggesting that ecological succession plays a role in structuring these communities.
共生体是细菌的独特栖息地。我们使用末端限制性片段长度多态性(T-RFLP)和焦磷酸测序技术,对多个亲缘关系密切的地衣个体的细菌群落的空间多样性进行了调查。地衣的中心区域拥有比物种贫乏且组成差异大的地衣边缘更为丰富和一致的组合,这表明生态演替在这些群落的结构形成中发挥了作用。
