Abstract Mycorrhizal symbiosis, specifically arbuscular mycorrhiza, is one of Earth's oldest and most widespread symbiosis. Existing evidence suggests that plant species differ in their associations with mycorrhizal partners, different reported to be always (obligately mycorrhizal, OM), sometimes (facultatively FM) or never (non‐mycorrhizal, NM) associating (AM) fungi this reliance on AM called status. However, very little known about how host status shapes the network topology interacting fungi.

Abstract Rhizosphere microbes play important roles in plant performance and ecosystem functioning. It is becoming increasingly clear that rhizosphere communities vary with soil properties variation root traits among species. However, less known about whether how within species influences the microbial communities. We evaluated intraspecific explored their associations bacterial fungal by focusing on an ectomycorrhizal tree species, Pinus massoniana , 22 sites subtropical China. The first dimension of principal component analysis revealed evidence for ‘conservation’ gradient economics space. Overall, explained more than rhizosphere. Functional composition changed significantly along gradient, fast‐growing copiotrophic bacteria symbiotic fungi were enriched ‘acquisition’ side, while slow‐growing oligotrophic side gradient.

The vast expanse of saline-alkali land in China represents a significant reserve resources for agricultural development. Therefore, it is essential to explore the tolerance crops, benefits soil improvement, and their carbon sequestration potential. This study utilized sorghum variety Jinliang 211 as experimental material, conducting trials woodland. A control four different treatments combining organic fertilizers amendments were established investigate effects these mixtures on growth, antioxidant enzyme activity, characteristics. results indicated that combined application fertilizer rice husk biochar could enhance salt 211, improve quality, increase capacity. Among measured plant indicators, T2 treatment (combined biochar) resulted highest dry matter accumulation, which was 68.4% higher than control. Concurrently, activities enzymes such SOD, POD, CAT significantly increased during jointing stage post-treatment, with observed treatment.

Abstract Soil phosphorus (P) availability is a crucial factor determining primary productivity in terrestrial ecosystem. Plant functional traits and microbes under P‐deficient conditions can respond positively to increase soil P bioavailability. Whether and/or how the fine‐root (FRTs) of deep‐rooted desert species affect rhizosphere bulk community phoD ‐harbouring bacteria thus improve P, however, remains unclear. We conducted three‐year artificial outdoor pot experiment supply using Alhagi sparsifolia Shap. (hereafter ) address this gap. Fine‐root samples from 1‐ 3‐year‐old seedlings rhizospheres were collected. High‐throughput sequencing, sequential extraction root system scanning used determine community, Hedley‐P fractions FRTs. surface area (RSA), specific length, foliar Mn concentration (indicating quantities carboxylates that are released) acid phosphatase (APase) activity significantly higher no‐P compared with high‐P conditions.

In addition significant effects species richness, we show that collaboration and conservation gradient are strong drivers composition different guilds fungi. Saprotrophic fungi most diverse species-rich communities with 'slow' traits, whereas pathogenic abundant 'fast' 'DIY' traits. Fungal biomass is strongly driven by richness.

Abstract The emergence of β‐diversity plant‐associated fungi across diverse coexisting host plant species in natural habitats is intricately linked to specific community assembly processes. Despite this, the relative contributions various processes observed patterns, as well influence traits on these contributions, are still poorly understood. Here, we investigated leaf/root‐associated fungal communities nine dominant herbaceous perennials a temperate grassland that had undergone 17‐year mowing treatment. We elucidated components and communities. Furthermore, explored relationships between leaf/root functional trait variations assemblies. tested following hypotheses: (1) both turnover nestedness important β‐diversity, with selection predominating assemblies; (2) enhances nestedness/selection; (3) significantly affect Unexpectedly, our findings demonstrated predominance among hosts, contrasting nestedness. Moreover, dispersal limitation emerged primary factor shaping assemblies, rather than Although inhibited growth, its effects overall patterns assemblages were limited. further higher degrees primarily stronger limitation, relatively weaker heterogeneous selection. Additionally, impact process root‐associated was more pronounced compared leaf‐associated fungi. Synthesis .
