AB  - Microplastics (MPs) occur and distribute widely in agroecosystems, posing a 
      potential threat to soil-plant systems. However, little is known about their 
      effects on legumes and N-fixing microbes. Here, we explored the effects of 
      high-density polyethylene (HDPE), polystyrene (PS), and polylactic acid (PLA) on 
      the growth of peanuts and soil N-fixing bacterial communities. All MPs treatments 
      showed no phytotoxic effects on plant biomass, and PS and PLA even increased 
      plant height, especially at the high dose. All MPs changed soil NO(3)(-)-N and 
      NH(4)(+)-N contents and the activities of urease and FDAse. Particularly, 
      high-dose PLA decreased soil NO(3)(-)-N content by 97% and increased soil urease 
      activity by 104%. In most cases, MPs negatively affected plant N content, and 
      high-dose PLA had the most pronounced effects. All MPs especially PLA changed 
      soil N-fixing bacterial community structure. Symbiotic N-fixer Rhizoboales were 
      greatly enriched by high-dose PLA, accompanied by the emergence of root 
      nodulation, which may represent an adaptive strategy for peanuts to overcome N 
      deficiency caused by PLA MPs pollution. Our findings indicate that MPs can change 
      peanut-N fixing bacteria systems in a type- and dose-dependent manner, and 
      biodegradable MPs may have more profound consequences for N biogeochemical 
      cycling than traditional MPs.
