This study aimed to investigate the influence of ectomycorrhizal fungi on nutrient uptake and activity enzymes alkaline phosphatase urease under pot conditions. In experiment, seedlings Persian oak (Quercus brantii) were inoculated with four species (Amanita crocea, Boletus comptus, Inocybe rimosa, Tricholoma giganteum) in three replicates. After seven months a greenhouse controlled humidity, various parameters examined, including leaf dry weight, percentage root colonization, concentration (N, P, Ca, Mg, Zn, Fe, Cu), enzyme activity. The results showed that all types contributed an increase concentration, N, K, Cu compared control group. treatments also differences comptus showing highest (87%). particular, rimosa giganteum significant success improving phosphatase. suggests potential these fungi, especially giganteum, can be utilized for establishment support regeneration forests affected by blight disease.

ABSTRACT Shrub encroachment significantly impacts biodiversity and ecosystem functions in grassland ecosystems. Soil microbial communities may play a key role this process. Previous studies have focused on plant competition soil abiotic factors, but the specific biological mechanisms by which microbiota drive shrub remained poorly understood. Through integrated vegetation surveys high‐throughput sequencing of across gradients Inner Mongolia, we assessed composition functional genes importance value. We found that value closely correlated with limited resources, including water nitrogen (N), during encroachment. Ectomycorrhizal (EcM) fungi were recruited semishrub Artemisia ordosica , increasing its competitiveness under conditions resource scarcity. Changes community affected N cycling reducing abundance involved fixation, nitrification, nitrate assimilation. Concurrently, shrubs preferred (NO 3 − ‐N) over herbaceous plants nutrient‐poor environments. The was facilitated EcM fungi, enabling them to thrive N‐deficient arid environments preferentially utilize NO ‐N. Our findings establish novel microbial‐mediated pathway driving encroachment, fungal symbionts enable host alleviate limitations through modified nutrient acquisition strategies. These results suggest targeted manipulation associations could inform restoration strategies shrub‐encroached grasslands highlight need for management approach accounts dynamics.

Endophytic bacteria within plant tissues play crucial roles in health, stress tolerance, and contribute to the metabolite diversity of host plants. Cannabis sativa L. is an economically significant plant, with industrial hemp (IH) medicinal (MC) being two main cultivars. However, composition functional traits their endophytic bacterial communities roots leaves are not well understood. In this study, DNA metabarcode sequencing were employed compare between IH MC. Significant differences observed root leaf niches. enriched stress-tolerant bacteria, while MC showed higher levels biofilm-forming bacteria. leaves, even more pronounced, particularly abundance Gram-negative potential pathogens, PICRUSt2 predictions revealed nitrogen metabolism secondary biosynthesis pathways different cultivars niches, FAPROTAX analysis highlighted variations carbon, nitrogen, sulfur cycling functions. These findings underscore distinct regulating responses, metabolic processes niches cultivars, providing insights for improving cultivation practices resilience.
