Introduced, invasive plants can alter local soil chemistry and  microbial communities, but the underlying mechanisms and extent of these  changes are largely unknown. Based on characteristics associated with  invasiveness in plants, it was hypothesized that introduced species that  produce large amounts of litter with distinctive secondary compounds can  a) alter the chemistry of both extractable and bulk carbon in the soil, b)  shift microbial communities towards microbes better able to metabolize the  compounds in the litter, and c) cause soil carbon chemistry and microbial  communities to shift to relatively uniform, novel states at multiple  sites. 2. Composition of phenolics in senescent tissues (leaves and roots)  of Polygonum cuspidatum was compared to the composition of extractable  phenolics and non-extractable bulk organic carbon in soils under and  adjacent to large, long-established stands of P. cuspidatum at four sites  in the eastern U.S. Rates of degradation of phenolics, activities of  enzymes associated with the breakdown of phenolics, and shifts in  microbial community composition were also measured at the sites. 3. Soils  under P. cuspidatum stands contained twice as much phenolics as adjacent  soils, but the composition of phenolics differed greatly between soils  under stands and senescent tissues of P. cuspidatum. Flavonoids and  proanthocyanidins constituted >90% of the identified phenolics in  P. cuspidatum tissues, whereas monophenolic compounds accounted for  > 90% of the phenolics in soils under stands. Soils under and  adjacent to stands also exhibited distinctive compositions of relatively  persistent bulk organic carbon; composition differed less between soils  under stands at different sites than between soils under and adjacent to  stands at the same site. 4. Soils under P. cuspidatum had 2.8 times  greater abundance of fungi than soils adjacent to stands, and fungal  markers showed clear separation of soils under and adjacent to P.  cuspidatum. However, the potential activity of enzymes that degrade  polyphenols was lower in soils under stands. Exogenously applied  chemically complex polyphenols persisted in both P. cuspidatum invaded and  adjacent non-invaded soils, whereas less complex compounds rapidly  disappeared from both soils. 5. Synthesis. Results suggest that  interactions between plant inputs, abiotic reactions, and biotic  transformations may create and maintain new states in invaded soils that  are chemically and biologically less diverse. In the case of polyphenol  rich, fast growing invasive species, these interactions may alter the  composition of bulk soil organic matter that has slower turnover rates,  resulting in legacy effects. Restoration could thus require, not just  removal of the species, but also post-removal interventions such as soil  amendments.", "keywords": ["Flavonoids", "Peroxidases", "Mass spectrometry", "tannins", "Fallopia japonica", "Japanese knotweed", "Reynoutria japonica", "Polyphenols", "home-field advantage", "Legacy effect", "15.
