Published: Jan. 1, 2024

Symbiosis of plants with arbuscular mycorrhizal (AM) fungi is arguably the most widespread inter-kingdom association in terrestrial ecosystems, implicated various ways ecosystem nutrient and carbon fluxes, biological diversity maintenance resistance resilience to a range (abiotic biotic) stresses. Here we present similarities specificities AM symbiosis effects on phosphorus (P) nitrogen (N) cycling ecosystems including those under agricultural use. We highlight important features relevant potential exploitation this ancient but largely invisible still not often purposefully managed interaction within framework production. also bring forward some partly controversial issues that consider need being given research priority broad societal attention successfully master transition from nonrenewable resources- fossil energy-based truly sustainable fully circular agriculture.

Abstract Introduction Inoculation of plants with beneficial microorganisms may improve plant performance yet suffers from efficacy variability. A solution might be the combined application different inoculants as consortium. The objective present study was to evaluate effects single or inoculation Trichoderma harzianum , strain TGFG411, and a consortium arbuscular mycorrhizal fungi (AMF) on growth, native microbial communities (here bacteria/archaea, AMF) in root‐associated soil (RAS) rhizosphere (RH), that is, loosely tightly attached roots, respectively. Materials Methods greenhouse experiment carried out non‐sterile agricultural model crop maize, which inoculated either TGFG411 AMF received + AMF. Control only water. Seven weeks after second inoculation, growth promotion capacity measured based shoot root parameters. Furthermore, RAS RH microbiota (fungi including AMF, bacteria archaea) were assessed via combination cultivation‐dependent, microscopic DNA‐based methods. Results After 7 maize both enhanced dry weight led significant reduction biomass. successfully established soil. However, no definite evidence for establishment found. Single modified composition total bacterial RH, whereas modulated fungal RAS. Conclusion did not result improvement compared likely due optimal nutrient supply. samples receiving exhibited distinct modulation RAS/RH microbiota, influence inoculant under less favourable conditions.

Abstract Himalayan balsam ( Impatiens glandulifera ) is one of the most invasive weeds across Europe. The rust fungus, Puccinia komarovii var. glanduliferae has been introduced as a biological control agent, but success patchy. Here, we investigated whether mycorrhizal and endophytic fungi can affect efficacy plant growth. Over three experiments, found that AM alone or together consistently reduced growth, this depended on identity species in inoculum. Meanwhile, increased infection frequency endophyte Colletotrichum acutatum . Rust inoculation had no detrimental effects colonisation C. infection, latter two sporulation. However, size was when all fungal types were present, suggesting combined inoculum offers promising approach for weed.
