摘要：Fusarium species, recognised as global priority pathogens, frequently induce severe diseases in crops; however, certain species exhibit alternative symbiotic lifestyles and are either non-pathogenic or endophytic. In this study, we characterised the mutualistic relationship between the eFp isolate of F. pseudograminearum and five poplar species, resulting in formation root structures reminiscent of ectomycorrhizal (ECM) symbiosis. This functional symbiosis is evidenced by enhanced plant growth, reciprocal nutrient exchange, improved nitrogen and phosphorus uptake and upregulation of root sugar transporter gene expression (PtSweet1). Comparative and population genomics confirmed that eFp maintains a structurally similar genome, but exhibits significant diver- gence from ten conspecific pathogenic isolates. Notably, eFp enhanced the growth of diverse plant lineages (Oryza,Arabidopsis, Pinus and non-vascular liverworts), indicating a near-complete loss of virulence. Although this specialised symbiosis has only been established in vitro, it holds significant value in elucidating the evolutionary track from endophytic to mycorrhizal associations.
