“…Microbial inoculants are used as an economically viable and environmentally friendly method that tailors microbes as renewable biofertilizers, and also as an alternative to replacing synthetic fertilizers and pesticides (Babalola & Glick, 2012; Bhattacharjee et al, 2023; Li et al, 2023; Liu et al, 2022; Poppeliers et al, 2023; Selvakumar et al, 2012). Such an eco‐friendly method helps promote agriculture by functioning as an organic biocontrol agent and biofertilizer, minimizing the effects of synthetic fertilizers and agrochemicals on agricultural fields and crop production, which often has adverse health and environmental effects.…”

“…Crop yield and health might be compromised in agricultural lands that lack healthy soil properties, whether under distressed or normal conditions, as well as poor organic carbon content. Crop rate of production was greatly improved in poor soils after introducing microbial inoculants (Bhattacharjee et al, 2023; Poppeliers et al, 2023; Tavasolee et al, 2011; Upadhyay et al, 2011; Vuolo et al, 2022; Wu, Cao, et al, 2014; Wu, Huang, et al, 2014).…”

Harnessing the power of microbes for sustainable development: Climate change mitigation and sustainable food security

The effects of releasing carbon from the terrestrial pool into the atmosphere have significant long‐term and short‐term implications that affect many parts of our globe. Agricultural fields might help to address these concerns and provide cost‐effective solutions, such as lowering carbon dioxide levels (CO2) in the atmosphere while raising carbon levels in the soil. In order to increase agricultural land's potential to absorb and store carbon, the proper selection of suitable microbial inoculants with the capability to sequester carbon into soils is critical. Soil quality and characteristics would improve as a result, and atmospheric carbon would therefore be reduced. Soil microbes have the potential to influence the level of organic matter, which has an impact on the soil's ecological system and characteristics. Soil microbes play a role in carbon sequestration in soils by regulating multiple and distinct pathways for CO2 inputs and losses, such as biochemical processes that could sequester CO2, the capacity to sediment carbonates, the rigid nature of their components and vegetative tissues, or the composition of complex substances that preserve carbon in the soil. Further research is needed to investigate if particular microbial strains that can sequester carbon will help enhance soil quality and prevent climate change.

“…28 The design of bioinoculants, however, often relies heavily on trial-and-error experiments, and the efficacy of the most promising microbe-based biofertilizers in laboratory settings may vary under different agricultural conditions. 29 Single microbial inoculants verified in the laboratory have difficulty simulating complex field conditions, which influences the effectiveness of the inoculant to a certain extent. Furthermore, various factors, such as the specific crop, edaphic conditions (e.g., pH, salinity, and soil type), biotic interactions (e.g., competition, parasites, and predators), and climatic influences, impede the effectiveness of commercial inoculants.…”

Nitrogen is the most limiting factor in crop production. Legumes establish a symbiotic relationship with rhizobia and enhance nitrogen fixation. We analyzed 1,624 rhizosphere 16S rRNA gene samples and 113 rhizosphere metagenomic samples from three typical legumes and three non-legumes. The rhizosphere microbial community of the legumes had low diversity and was enriched with nitrogen-cycling bacteria (Sphingomonadaceae, Xanthobacteraceae, Rhizobiaceae, and Bacillaceae). Furthermore, the rhizosphere microbiota of legumes exhibited a high abundance of nitrogen-fixing genes, reflecting a stronger nitrogen-fixing potential, and Streptomycetaceae and Nocardioidaceae were the predominant nitrogen-fixing bacteria. We also identified helper bacteria and confirmed through metadata analysis and a pot experiment that the synthesis of riboflavin by helper bacteria is the key factor in promoting nitrogen fixation. Our study emphasizes that the construction of synthetic communities of nitrogen-fixing bacteria and helper bacteria is crucial for the development of efficient nitrogen-fixing microbial fertilizers.

“…However, the natural rhizosphere environment presents significant differences that make effective application of bioinoculants in agriculture difficult. Successful colonization of the rhizosphere depends on edaphic factors, -factors such as soil chemistry and structure-, host genotype, and, particularly, the complex web of microbial interactions in the rhizosphere microbiome that results in a strong resistance to invasion (Poppeliers et al, 2023). Consequently, many promising bioinoculants fail to exert their positive effects or show variable efficacies in the field.…”

ThePseudomonasgenus has shown great potential as a sustainable solution to support agriculture through its plant-growth promoting and biocontrol activities. However, their efficacy as bioinoculants is limited by unpredictable colonization in natural conditions. Our study identifies theiollocus, a gene cluster inPseudomonasinvolved in inositol catabolism, as a feature enriched among superior root colonizers in natural soil. Further characterization revealed that theiollocus increases competitiveness by inducing swimming motility and fluorescent siderophore production in response to inositol, a plant-derived compound. Public data analyses indicate that theiollocus is broadly conserved in thePseudomonasgenus and linked to diverse host-microbe interactions. Our findings suggest theiollocus as a potential target for developing more effective bioinoculants, given its conservation and association with diverse host-microbe interactions.
