New Phytologist, Journal Year: 2024, Volume and Issue: 242(6), P. 2401 - 2410

Published: March 17, 2024

Summary The rhizosphere microbiome plays critical roles in plant growth and provides promising solutions for sustainable agriculture. While the frequently fluctuates with soil environment, recent studies have demonstrated that a small proportion of is consistently assembled specific genotype regardless condition, which determined by host genetics. Based on these breakthroughs, involved exploiting plant‐beneficial function microbiome, we propose to divide into environment‐dominated genetic‐dominated components based their different assembly mechanisms. Subsequently, two strategies explore agricultural production are suggested, is, precise management agronomic practices, elucidation genetic basis breeding microbiome‐assisted crop varieties. We finally present major challenges need be overcome implement modulating microbiome.

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

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.

Microbiome-Mediated Strategies to Manage Major Soil-Borne Diseases of Tomato

Plants, Journal Year: 2024, Volume and Issue: 13(3), P. 364 - 364

Published: Jan. 25, 2024

The tomato (Solanum lycopersicum L.) is consumed globally as a fresh vegetable due to its high nutritional value and antioxidant properties. However, soil-borne diseases can severely limit production. These diseases, such bacterial wilt (BW), Fusarium (FW), Verticillium (VW), root-knot nematodes (RKN), significantly reduce the yield quality of tomatoes. Using agrochemicals combat these lead chemical residues, pesticide resistance, environmental pollution. Unfortunately, resistant varieties are not yet available. Therefore, we must find alternative strategies protect tomatoes from diseases. One most promising solutions harnessing microbial communities that suppress disease promote plant growth immunity. Recent omics technologies next-generation sequencing advances help us develop microbiome-based mitigate This review emphasizes importance interdisciplinary approaches understanding utilization beneficial microbiomes improve crop productivity.
