Abstract Climate change-driven extreme events are reducing barley productivity. The high use of mineral fertilizers, combined with low nutrient efficiency, leads to environmental and economic concerns. Indigenous arbuscular mycorrhizal fungi (AMF) inoculants offer a sustainable alternative, especially in intensive farming systems where AM colonization diversity low. However, poor adaptation local conditions limits inoculant success. Few studies have tested indigenous AMF inoculated on field crops, limited research barley. No has yet explored how genotype environment modulate inoculation outcomes terms crop Key factors such as fungal abundance community structure shifts remain unidentified. This study evaluated the agroecological effects an consortium three varieties (Atlante, Atomo, Concerto) over 2 years. In 2020, Atomo Concerto responded positively root colonization, grain yield increases 64% 37%, respectively. 2021, only showed enhanced while increased by 78% 134% Atlante. Multivariate analysis revealed strong impact productivity, significant third-order interaction among AMF, genotype, environment. Inoculation slightly altered composition but strongly influenced structure, particularly at different plant growth stages. Root was correlated length containing arbuscules being best predictor. Changes rather than composition, drove response, Glomus Septoglomus , present inoculum, main players. These findings support for biofertilization highlight importance selecting genotypes stable response across environments. Our results disclose first time role stage host preference without inoculants.

The overuse of chemical fertilizers not only leads to resource wastage but also causes problems such as environmental pollution and soil degradation. In particular, crop growth in saline–sodic soils is severely restricted due high salinity alkalinity, further exacerbating challenges agricultural production. aim this study was investigate different fertilization strategies that combine fertilizer reduction with arbuscular mycorrhizal fungi (AMF) for improving assess the effects these protocols on yield, properties, microbial communities. Field experiments across two sites (BeiWuLao XuJiaZhen) demonstrated integrating AMF CF (AHCF treatment) significantly enhanced maize yield by 23.5% at BeiWuLao (from 11,475 14,175 kg/ha) 81.2% XuJiaZhen 7245 13,125 compared conventional (CK) (p < 0.01). Soil nutrient analysis revealed substantial improvements: available potassium (AK) increased 77.7% (61.35 vs. 39.33 mg/kg), phosphorus (AP) 33.9% (20.50 15.50 ammonium nitrogen (AN) 57.3% (64.17 40.83 organic matter (SOM) 96.4% (46.98 23.91 mg/kg) under AHCF treatment 0.05). Although pH electrical conductivity (ECe) remained unaffected, inoculation shifted composition, elevating salinity-tolerant taxa Actinobacteria (+24.7%) Anabaena. Beta diversity (PCoA) confirmed distinct community structures between treatments, ECe AN identified primary drivers bacterial (RDA variance: 74.08%) fungal 54.63%) communities, respectively. Overall, combination effectively improved fertility, structure, yield. These findings have important implications saline promoting sustainability.

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.

Functional team selection: a framework for local adaptation in plants and their belowground microbiomes

Опубликована: Апрель 9, 2024

Plants and their microbiomes are complex adaptive systems consisting of host plants a dynamic network associated microorganisms inside around plant tissues. This article introduces Functional Team Selection (FTS) as framework to help envision study the movement matter, energy, information within plant-microbiome systems. FTS embraces fact that belowground, surrounded by trillions soil organisms may or hinder function roots provide essential resources for photosynthetic production. We describe how limited antagonistic biotic interactions drive host-mediated microbiome engineering belowground can be selected -even during host’s lifespan- generate adaptation in stressful but not benign environments. The provides guidelines work with, rather than against, evolutionary ecological forces durable cooperation mutualism microbiome.

Abstract Arbuscular mycorrhizal (AM) fungi are important plant symbionts that provide plants with nutrients and water as well support defences against pests disease. Consequently, they present a promising alternative to using environmentally damaging costly fertilisers pesticides in agricultural systems. However, our limited understanding of how practices impact AM fungal diversity functions is key impediment them effectively agriculture. We assessed organic conventional management systems shaped communities. also investigated communities derived from these affected crop biomass development. Six soil samples five organically conventionally managed sites were used cultivate Sorghum bicolor . Plant growth, nutrient concentrations colonisation rates analysed alongside DNA metabarcoding community composition. observed fields resulted pronounced reduction sorghum (−53.6%) significant delay flowering compared grown without fungi. was reduced the system, but lesser extent (−30%) flowering. Organic associated large proportion taxa (50.5% VTs) not found systems, including Diversispora ( r 2 = 0.09, p < 0.001), Archaeospora 0.07, 0.001) Glomus 0.25, spp., shared (42.3% VTs). Conventional had relatively few unique (7.2% Our results suggest selected were, this context, more beneficial for host plants.
