AB  - Although various persistent organic pollutants (POPs) can affect microbial 
      communities and functions in aquatic ecosystems, little is known about how 
      bacteria and microeukaryotes respond to the POPs in sediments planted with 
      different submerged macrophytes. Here, a 60-day microcosm experiment was carried 
      out to investigate the changes in the diversity and interaction of bacterial and 
      microeukaryotic communities in sediments collected from Taihu lake, either with 
      decabromodiphenyl ether (BDE-209) own or combined with two common submerged 
      macrophyte species (Vallisneria natans and Hydrilla verticillate). The results 
      showed that BDE-209 significantly decreased the bacterial alpha-diversity but 
      increased the microeukaryotic one. In sediments planted with submerged 
      macrophytes, the negative effect of BDE-209 on bacterial diversity was weakened, 
      and its positive effect on microeukaryotic one was strengthened. Co-occurrence 
      network analysis revealed that the negative relationship was dominant in 
      bacterial and microeukaryotic communities, while the cooperative relationship 
      between microbial species was increased in planted sediments. Among nine keystone 
      species, one belonging to bacterial family Thermoanaerobaculaceae was enriched by 
      BDE-209, and others were inhibited. Notably, such inhibition was weakened, and 
      the stimulation was enhanced in planted sediments. Together, these observations 
      indicate that the responses of bacteria and microeukaryotes to BDE-209 are 
      different, and their communities under BDE-209 contamination are more stable in 
      sediments planted with submerged macrophytes. Moreover, the effects of plant 
      species on the microbial responses to BDE-209 need to be explored by more 
      specific field studies in the future.
