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

New Phytologist, Journal Year: 2024, Volume and Issue: 243(4), P. 1506 - 1521

Published: June 14, 2024

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.

Plant Diversity Reduces the Risk of Antibiotic Resistance Genes in Agroecosystems

Advanced Science, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 28, 2025

Abstract Despite advances in dispersal mechanisms and risk assessment of antibiotic resistance genes (ARGs), how plants influence ARG contamination agricultural soils remains underexplored. Here, the impacts plant species diversity on ARGs mobile genetic elements (MGEs) three are comprehensively investigated a pot experiment. The results indicate that increased reduces MGEs abundance by 19.2%–51.2%, whereas exhibit inconsistent soil‐dependent effects. Potential bacterial hosts harboring abundant have greater relative than nonhosts, both their richness cumulative reduced diversity. Notably, inhibited present other hosts. enriched compounds root exudates due to play more important role metabolic network contribute rebalancing potential nonhosts. An independent test using pure organics reveals higher resource diversity, resulting from mobility high‐risk ARGs. This study highlights resource‐mediated mitigation risks posed indicates ensuring is promising strategy for controlling agroecosystems.

Consortium of Phosphorus-Solubilizing Bacteria Promotes Maize Growth and Changes the Microbial Community Composition of Rhizosphere Soil

Agronomy, Journal Year: 2024, Volume and Issue: 14(7), P. 1535 - 1535

Published: July 15, 2024

Phosphorus deficiency severely limits crop yields and hinders sustainable agricultural development. Phosphate-solubilizing bacteria (PSB) are beneficial for growth because they enhance the uptake utilization of phosphorus. This study explored phosphorus-solubilizing, IAA-producing, nitrogen-fixing, potassium-solubilizing, siderophore-producing abilities three bacterial strains (Pantoea sp. J-1, Burkholderia cepacia Z-7, Acinetobacter baumannii B-6) screened from maize rhizosphere. A pot experiment was also conducted to explore role PSB in maize. Finally, effects on physicochemical properties, enzyme activities, microbial community structure rhizosphere soil were analyzed. The results showed that strain Z-7 had strongest phosphorus solubilization, nitrogen fixation, potassium siderophore production, while J-1 exhibited highest yield IAA. application promoted plants different extents. Among treatments, mixed treatment (J-1 + most potent promotion effect, consortium significantly enhanced activity phosphatase. Soil pH, total (TP), (TK), available (AP), NH4+-N, NO3−-N key factors plants. In addition, altered soil, relative abundance Proteobacteria increased by 16.07–69.10% compared control. These have obvious growth-promoting abilities, with potential productivity as excellent candidate development biological fertilizers.
