Intercropping enhances maize growth and nutrient uptake by driving the link between rhizosphere metabolites and microbiomes

New Phytologist, Год журнала: 2024, Номер 243(4), С. 1506 - 1521

Intercropping leads to different plant roots directly influencing belowground processes and has gained interest for its promotion of increased crop yields resource utilization. However, the precise mechanisms through which interactions between rhizosphere metabolites microbiome contribute production remain ambiguous, thus impeding understanding yield-enhancing advantages intercropping. This study conducted field experiments (initiated in 2013) pot experiments, coupled with multi-omics analysis, investigate plant-metabolite-microbiome maize. Field-based data revealed significant differences metabolite profiles soils maize monoculture In particular, intercropping exhibited higher microbial diversity chemodiversity. The chemodiversity composition were significantly related diversity, community composition, network complexity soil microbiomes, this relationship further impacted nutrient uptake. Pot-based findings demonstrated that exogenous application a metabolic mixture comprising key components enriched by (soyasapogenol B, 6-hydroxynicotinic acid, lycorine, shikimic phosphocreatine) enhanced root activity, content, biomass natural soil, but not sterilized soil. Overall, emphasized significance metabolite-microbe enhancing systems. It can provide new insights into controls within intensive agroecosystems, aiming enhance ecosystem services.

ABSTRACT Unraveling how agricultural management practices affect soil biota network complexity and stability these changes relate to processes functions is critical for the development of sustainable agriculture. However, our understanding knowledge still remains unclear. Here, we explored effects intensity on complexity, stability, multifunctionality, as well relationships among factors. Four typical land use types representing a gradient disturbance were selected in calcareous red soils southwest China. The four with increasing included pasture, sugarcane farmland, rice paddy fields, maize cropland. cohesion, topological features (e.g., average degree, clustering coefficient, path length, diameter, graph density, modularity), variation degree used evaluate strength interactions between species, respectively. results showed that intensive increased species competition but decreased stability.

Dual roles of microbes in mediating soil carbon dynamics in response to warming

Abstract Understanding the alterations in soil microbial communities response to climate warming and their controls over carbon (C) processes is crucial for projecting permafrost C-climate feedback. However, previous studies have mainly focused on microorganism-mediated C release, little known about whether how affects anabolism subsequent input regions. Here, based a more than half-decade of situ experiment, we show that compared with ambient control, significantly reduces use efficiency enhances network complexity, which promotes heterotrophic respiration. Meanwhile, necromass markedly accumulates under likely due preferential decomposition plant-derived C, further leading increase mineral-associated organic C. Altogether, these results demonstrate dual roles microbes affecting release stabilization, implying feedback would weaken time dampened respiration increased proportion stable pool.

Arbuscular mycorrhizal fungi (AMF) and biochar application individually can enhance plant tolerance to saline-alkali stress promote growth efficiency. However, little is known about the potential synergistic effects of their combination on improving soil quality under stress. This experiment adopted potted method explore four treatments switchgrass quality: (BC), Rhizophagus irregularis (Ri), + Ri (BR) a control without or (CK). Compared CK treatment, biomass increased by 92.4 %, 148.6 177.3 % in BC, Ri, BR treatment groups, respectively. Similarly, rhizosphere index 29.33 22.7 49.1 respective groups. The significantly altered microbial composition diversity. Notably, compared other treatments, archaeal α-diversity group showed significant decrease. relative abundance bacteria, archaea at genus level (e.g., Bacillus, Trichome candidatus_methanopenens). Network analysis that complexity closeness interactions between different taxa were stronger than with being more prominent. In summary, combined has better effect promoting stress, soil, increasing study provides new approach for efficient development utilization land.
