Microbial community structures associated with halophytes and their compositions among different habitats, particularly natural saline sites, have not yet been investigated in detail. In the present study, we examined the diversity and composition of the rhizosphere and root endosphere bacteria of two halophytes, Salicornia europaea L. and Glaux maritima L., collected from two adjacent brackish lakes, Lake Notoro and Lake Tofutsu, in Japan. The bacterial species richness and diversity indices of the two halophytes collected from both lakes showed no significant differences in the rhizosphere or root endosphere. In contrast, beta diversity and taxonomic analyses revealed significant differences in the bacterial communities from each halophyte between the two lakes even though the two locations were natural saline sites, indicating that the bacterial communities for S. europaea and G. maritima both fluctuated in a manner that depended on the geographical location. Common and abundant genera associated with each halophyte across the two lakes were then identified to verify the bacterial genera specifically inhabiting each plant species. The results obtained showed that the composition of abundant genera inhabiting each halophyte across two lakes was distinct from that reported previously in other saline soil areas. These results suggest that each halophyte in different geographical sites had an individual complex bacterial community.

细菌多样性，并在两个盐生植物，根际和根Endosphere群落结构的比较分析海蓬子和Glaux袍，在日本从两个咸水湖泊收集

与盐生植物相关的微生物群落结构及其在不同生境，特别是天然盐碱地的组成，尚未得到详细研究。在本研究中，我们检测了两种盐生植物 Salicornia europaea L. 和 Glaux maritima L. 的根际和根内层细菌的多样性和组成，这些植物是从日本两个相邻的咸水湖——能取湖和东富津湖采集的。从两个湖泊收集的两种盐生植物的细菌物种丰富度和多样性指数在根际或根内圈中没有显着差异。相比之下，β 多样性和分类学分析揭示了两个湖泊之间每种盐生植物的细菌群落存在显着差异，尽管这两个位置是天然盐碱地，表明 S. europaea 和 G. maritima 的细菌群落都以取决于地理位置的方式波动。然后确定了与两个湖泊中每个盐生植物相关的常见和丰富的属，以验证专门栖息在每个植物物种中的细菌属。获得的结果表明，栖息在两个湖泊中每个盐生植物的丰富属的组成与先前在其他盐渍土壤地区报道的不同。这些结果表明，不同地理位置的每种盐生植物都有一个复杂的细菌群落。然后确定了与两个湖泊中每个盐生植物相关的常见和丰富的属，以验证专门栖息在每个植物物种中的细菌属。获得的结果表明，栖息在两个湖泊中每个盐生植物的丰富属的组成与先前在其他盐渍土壤地区报道的不同。这些结果表明，不同地理位置的每种盐生植物都有一个复杂的细菌群落。然后确定了与两个湖泊中每个盐生植物相关的常见和丰富的属，以验证专门栖息在每个植物物种中的细菌属。获得的结果表明，栖息在两个湖泊中每个盐生植物的丰富属的组成与先前在其他盐渍土壤地区报道的不同。这些结果表明，不同地理位置的每种盐生植物都有一个复杂的细菌群落。
