Arbuscular mycorrhizal fungi (AMF) influence silicon (Si) uptake by plants, but the mechanisms remain unclear. This study investigated of AMF-mediated Si rice, a model Si-accumulating plant, and explored tripartite interactions among AMF, Si, phosphorus (P). AMF inoculation increased shoot content 97% when supplied with silicic acid 29% calcium silicate upregulated expression transporters

Growing in phosphorus‐impoverished habitats in south‐western Australia: How general are phosphorus‐acquisition and ‐allocation strategies among Proteaceae, Fabaceae and Myrtaceae species?

Numerous phosphorus (P)-acquisition and -utilisation strategies have evolved in plants growing severely P-impoverished environments. Although these been well characterised for certain taxa, like Proteaceae, P-poor habitats are by a high biodiversity, we know little about how species other families cope with P scarcity. We compared the P-acquisition leaf P-allocation of Fabaceae Myrtaceae those Proteaceae same habitat. exhibited multiple strategies: P-mining carboxylates or phosphatases, uptake facilitated carboxylate-releasing neighbours, dependence on elevated soil availability after fire. Surprisingly, not all showed photosynthetic P-use efficiency (PPUE). Highly P-efficient positive correlations between PPUE proportion metabolite (enzyme substrates), negative phospholipids (cellular membranes) nucleic acid (mostly ribosomal RNA), while found no less species. Overall, that used wider range than to scarcity, at both rhizosphere level. This knowledge is pivotal better understand mechanisms underlying plant survival nutrient-impoverished biodiverse ecosystems.

Mycorrhizal symbioses are complex relationships between plants and fungi that significantly affect ecosystem dynamics functions across terrestrial environments. These symbiotic interactions, which involve a diverse range of fungal lineages, including Mucoromycotina, Glomeromycotina, Ascomycota, Basidiomycota, as well various plant hosts, critical for nutrient cycling, carbon sequestration, growth, resilience both partners to environmental stressors. Recent advances in molecular biology, genetics, sciences have enhanced our understanding mycorrhizal illuminated the mechanisms govern these intricate interactions their ecological implications.

Summary The response of arbuscular mycorrhizal (AM) symbiosis to environmental fluctuations involves resource exchange between host plants and fungal partners, associations different AM taxa, biomass allocation spore hyphal structures; yet a systematic understanding these responses meadow degradation remains relatively unknown, particularly in Xizang alpine meadow. Here, we approached this knowledge gap by labeling dual isotopes air 13 CO 2 soil 15 NH 4 Cl, computing ecological networks communities, quantifying among spores, intra‐ extraradical hyphae. We found that the ratio photosynthate nitrogen fungi increased with increasing severity degradation, indicating greater dependence on for acquisition. Additionally, using 18S rRNA gene metabarcoding, co‐occurrence were more complex degraded meadows, supporting stress gradient hypothesis. Meadow also toward traits associated hyphae at expense spores. Our findings suggest an integrated consideration exchange, networks, may be important restoration ecosystems.

Mycelium biomass and community composition impact nutrient concentration in arbuscular mycorrhizal fungi at fine spatial scale

Abstract The dynamic exchange of carbon (C) and nutrients between arbuscular mycorrhizal (AM) fungi their host plants is crucial for shaping the spatial heterogeneity within hyphal network. This influenced not only by mycelial growth its interactions with but also variability soil nutrients. Despite importance, network factors driving this remain poorly understood. In field plant–AM interactions, many studies have predominantly concentrated on large‐scale patterns, disregarding at fine scales potentially missing vital insights into nutrient AM fungi. We conducted an experiment to quantify plant–soil–mycelia a gridded 2 × m quadrat. Hyphal in‐growth bags were installed extract pure mycelium. concentrations C ([C]), nitrogen ([N]), phosphorus ([P]) in both plant mycelium tissues measured. Additionally, fungal community from extracted hyphae was sequenced assess composition. Mycelium [N] [P] ranged 2.18% 3.37% 0.99% 4.46%, respectively, variations much higher than those shoot root tissues. stored significant amounts nutrients, particularly (2.27% average), levels exceeding found tissue over 20‐fold.
