Plant roots aid the growth and functions of several kinds microorganisms such as plant growth-promoting rhizobacteria, mycorrhizal fungi, endophytic bacteria, actinomycetes, nematodes, protozoans which may impart significant impacts on health growth. soil–microbe interaction is an intricate, continuous, dynamic process that occurs in a distinct zone known rhizosphere. Plants interact with these soil microbes variety ways, including competitive, exploitative, neutral, commensal, symbiotic relationships. Both types were found to have impact community diversity structure rhizosphere, or vice versa. The thought be essential for management quality because it has different biocontrol effects could very advantageous host alter physiology nutrition. composition microbial influenced by type. Besides beneficial microbes, also harbors are detrimental plants, competing nutrients space, causing diseases. Numerous antagonistic activity ability defend plants from soil-borne study microbiome formulating strategies transforming rhizosphere benefit plants. This review pays special emphasis populations how they influence growth, nutrient acquisition, inter-relationships between stress resistance, carbon sequestration, phytoremediation.

The soil microbiome plays an important role in maintaining health, plant productivity, and ecosystem services. Current molecular-based studies have shed light on the fact that has been quantitatively underestimated. In addition to metagenomic studies, metaproteomics metatranscriptomic target functional part of are becoming more common. These for a better understanding deciphering plant-microbe interactions. Free-living beneficial bacteria promote growth by colonizing roots called growth-promoting rhizobacteria (PGPRs). They exert their effects different ways, either facilitating uptake nutrients synthesizing particular compounds plants or preventing protecting from diseases. A interactions both natural agroecosystems will offer us biotechnological tool managing fertility obtaining high-yield food production system.

Abstract Sustainable increase in agriculture productivity is confronted by over‐reliance and over‐use of synthetic chemical fertilizers. With a market projection $5.02 billion 2030, biofertilizers are gaining momentum as supplement and, some cases, an alternative to Biofertilizers can improve the nutritional supply plant simultaneously soil health, reduce greenhouse emissions, hence directly contribute towards environmental sustainability. Plant growth‐promoting microbes (PGPMs) particularly receiving significant attention biofertilizers. They widely known for their ability growth via increasing nutrient availability use efficiency. However, except few successful commercialization PGPM‐based inoculants still limited, mainly due lack field efficacy consistency. Lack effective formulation technologies that keep microbial viable during storage, transport application considered one key factors drive inconsistent In this review, we identify current challenges associated with inoculants. We propose future paths, including advancement potentially efficient, eco‐friendly cost‐effective. argue enhance global adoption biofertilizers, new innovations based on transdisciplinary approaches indispensable. The emerging framework should encompass robust quality control system at all stages. Additionally, active partnership between academic industry stakeholders will pave way enhanced

Introduction While co-inoculation with rhizobia and plant growth-promoting rhizobacteria (PGPR) can enhance soybean growth nodulation, the interaction mechanisms between Bacillus velezensis 20507 Bradyrhizobium japonicum USDA110 under varying nitrogen (N) supply levels (0–10 mmol/L) remain unclear. This study investigates how their synergistic interactions influence content per molecular pathways. Methods Soybean plants were co-inoculated B. across four N levels. Nodulation, growth, physiology, quantified. Transcriptome sequencing of roots deficiency compared single treatments. Flavonoids in fermentation broth identified via mass spectrometry, rutin’s regulatory effects on nodulation genes (NodD1/NodD2) tested coculture. Results Co-inoculation significantly increased biomass, to inoculations all Under deficiency, induced 5,367 differentially expressed (DEGs), Kyoto Encyclopedia Genes Genomes (KEGG) enrichment phenylpropanoid (ko00940) flavonoid biosynthesis (ko00941). produced 29 flavonoids 4 isoflavonoids (including rutin). Rutin (5–10 mg/L) upregulated NodD1 suppressed NodD2 . Discussion enhances japonicum-soybean symbiosis secretion, particularly rutin, which modulates gene expression. metabiotic improves assimilation even low conditions. The findings provide a foundation for designing composite inoculants optimize yield nitrogen-use efficiency.
