AB  - The widespread existence of microplastics (MPs) in soil has been extensively 
      demonstrated, and their presence would ineluctably change soil physicochemical 
      properties and microbial community composition. However, there is limited 
      understanding of how MPs affect soil microbial assembly. In this study, three 
      different polymer types of MPs, i.e., high-density polyethylene (HDPE), 
      polystyrene (PS), and polylactic acid (PLA), with the same particle size (100 mum) 
      and dose (2%) were applied under the planted and unplanted condition, Pennisetum 
      alopecuroides was chosen as a model species. Plant growth parameters, soil 
      physicochemical properties, and microbial communities (including bacteria and 
      eukaryotes) were determined. The assembly and the co-occurrence network of 
      microbial communities were analyzed. Results revealed that the effect of MPs on 
      soil physicochemical properties was type-dependent and could influenced by the 
      presence of P . alopecuroides. MPs could enrich bacterial genera related to 
      nitrogen cycle and some pathogens of eukaryotes. The presence of MPs changed 
      bacterial and eukaryotic community assembly, in which diversity drove the 
      deterministic/stochastic assembly processes. MPs addition increased the 
      complexity of bacterial network, while had a minor effect on eukaryotic network. 
      The inhibition of MPs on P . alopecuroides growth decayed over time, HDPE MPs was 
      more harmful to P . alopecuroides growth than PS and PLA MPs. Our findings 
      enormously improved our comprehensions of MPs-induced ecological impacts and 
      interactions of soil bacterial and eukaryotic communities .
