Plants have evolved symbioses with mycorrhizal and endophytic fungi that are essential for their growth survival. While most plants associate a single guild of fungi, select group termed “dual-mycorrhizal plants” both arbuscular ectomycorrhizal fungi. Although shift from to colonization plant development has been demonstrated on other dual-mycorrhizal hosts, it is not known how shifts age in Populus species. We performed an in planta mycorrhization experiment test the occurrence switching response host-specific patterns fungal two species (P. tremuloides P. trichocarpa). found only trichocarpa displayed colonization, while associated but On trichocarpa, guilds increased abundance age, root decreased. Many early-colonizing we documented strong saprotrophic capabilities, which may be important trait fast colonization. Dark septate endophytes were more abundant than either likely functionally members community. Our findings represent novel pattern illustrate vary association results also stress importance “third guild” symbionts – dark plants.

Pine wilt disease (PWD) poses a significant threat to pine forest health, making sanitation thinning of infected trees and cultivation disease-resistant stands crucial measures for ecosystem restoration. To date, limited studies have systematically investigated how post-sanitation planting pine-wilt-disease-resistant Pinus species affects soil microbiome, especially regarding bacterial fungal diversity characteristics, functional succession patterns, community assembly processes. In this study, we performed comparative analysis microbial characteristics biochemical properties between experimental plots subjected those replanted with species. The results indicated that compared the sanitation-thinned plot, (Pinus taeda plot thunbergii plot) exhibited significantly higher activities β-glucosidase (S-β-GC), N-acetyl-β-D-glucosidase (S-NAG), arylsulfatase (S-ASF). Compared logging stands, our revealed evenness (OTUs), greater abundance more unique taxa. Furthermore, edaphic properties—specifically moisture content (SMC), pH levels, total potassium (TK)—significantly influenced structures communities. wood saprotrophic fungi ectomycorrhizal increased in both P. plot. null models enhanced undominated processes bacteria fungi. summary, data elucidate differences responses forests undergoing due cultivated resistance. This deepens understanding functions within these ecosystems.
