植物入侵可以改变土壤有机质组成，间接影响河口生态，因此，了解植物入侵如何影响细菌群落是至关重要的。本研究采用16 S rRNA基因绝对定量测序技术对大叶藻和互花米草覆盖区的细菌群落进行了研究。黄河口粳稻退化区。我们的数据显示，表层的细菌绝对数量显著（p <0.05）高于底层和降解区。随着S.互花米草中类杆菌属、酸性微生物科和脱卤球菌科的丰度较高;互花米草沉积此外，沉积物细菌群落在门水平上的组成变化与总有机碳（TOC）的关系最为密切，重金属的含量会降低细菌的丰度。本研究为了解S.互花米草入侵Z.从微生物组水平的角度来看，表层细菌绝对数量高于其他区域。互花米草的入侵增加了细菌群落的丰度。硫酸盐还原菌和黄杆菌科是海草床中的优势细菌。
Plant invasion can alter soil organic matter composition and indirectly impact estuary ecology; therefore, it is paramount to understand how plant invasion influences the bacterial community. Here, we present an absolute quantification 16S rRNA gene sequencing to investigate the bacterial communities that were collected from Zostera japonica and Spartina alterniflora covered areas and Z. japonica degradation areas in the Yellow River Estuary. Our data revealed that the absolute quantity of bacteria in the surface layer was significantly (p < .05) higher than that in the bottom and degradation areas. Following the invasion of S. alterniflora, the abundances of Bacteroidia, Acidimicrobiaceae, and Dehalococcoidaceaewere enriched in the S. alterniflora sediment. In addition, variations in the composition of sediment bacterial communities at the phylum level were the most intimately related to total organic carbon (TOC), and the content of heavy metals could reduce the abundance of bacteria. This study provided some information to understand the effects of S. alterniflora invasion on Z. japonica from the perspective of microbiome level. The absolute quantity of surface layer bacteria was higher than the other area. Spartina alterniflora invasion increased the bacterial community abundance. The Sulfate‐Reducing Bacteria and Flavobacteriaceae are dominant bacteria in seagrass beds.
