AB  - Human industrial activities have left millions of hectares of land polluted with 
      trace element metals and persistent organic pollutants (POPs) around the world. 
      Although contaminated sites are environmentally damaging, high economic costs 
      often discourage soil remediation efforts. Phytoremediation is a potential green 
      technology solution but can be challenging due to the diversity of anthropogenic 
      contaminants. Co-cropping could provide improved tolerance to diverse soil 
      challenges by taking advantage of distinct crop capabilities. Co-cropping of 
      three species with potentially complementary functions, Festuca arundinacea, 
      Salix miyabeana and Medicago sativa, perform well on diversely contaminated 
      soils. Here, rhizosphere microbiomes of each crop in monoculture and in all 
      co-cropping combinations were compared using 16S rRNA gene amplification, 
      sequencing and differential abundance analysis. The hyperaccumulating F. 
      arundinacea rhizosphere microbiome included putative plant growth promoting 
      bacteria (PGPB) and metal tolerance species, such as Rhizorhapis suberifaciens, 
      Cellvibrio fibrivorans and Pseudomonas lini. The rhizosphere microbiome of the 
      fast-growing tree S. miyabeana included diverse taxa involved in POP degradation, 
      including the species Phenylobacterium panacis. The well-characterised 
      nitrogen-fixing M. sativa microbiome species, Sinorhizobium meliloti, was 
      identified alongside others involved in nutrient acquisition and putative 
      yet-to-be-cultured Candidatus saccharibacteria (TM7-1 group). The majority of 
      differentially abundant rhizosphere-associated bacterial species were maintained 
      in co-cropping pairs, with pairs having higher numbers of differentially abundant 
      taxa than monocultures in all cases. This was not the case when all three crops 
      were co-cropped, where most host-specific bacterial species were not detected as 
      differentially abundant, indicating the potential for reduced rhizosphere 
      functionality. The crops cultivated in pairs here retained rhizosphere microbiome 
      bacteria involved in these monoculture ecosystem services of plant growth 
      promotion, POP tolerance and degradation, and improved nutrient acquisition. 
      These findings provide a promising outlook of the potential for complementary 
      co-cropping strategies for phytoremediation of the multifaceted anthropogenic 
      pollution which can disastrously affect soils around the world.
