Rhizosphere interactions from plant-soil-microbiome occur dynamically all the time in "black microzone" underground, where we can't see intuitively. metabolites including root exudates and microbial act as various chemical signalings involving rhizosphere interactions, play vital roles on plant growth, development, disease suppression resistance to stress conditions well proper soil health. Although are a mixture roots microbes, they often discussed alone. As rapid appearance of omics platforms analytical methods, it offers possibilities opportunities for exploring unprecedented breadth depth. However, our comprehensive understanding about fine-tuning mechanisms mediated by these compounds still remain clear. Thus, this review summarizes recent advances systemically features their effects ecosystem, looks forward future research perspectives, which contributes facilitating better biochemical communications belowground helping identify novel metabolites. We also address challenges promoting different environmental stresses.

Maize and cowpea are among the staple foods most consumed by of African population, significant importance in food security, crop diversification, biodiversity preservation, livelihoods. In order to satisfy growing demand for agricultural products, fertilizers pesticides have been extensively used increase yields protect plants against pathogens. However, excessive use these chemicals has harmful consequences on environment also public health. These include soil acidification, loss biodiversity, groundwater pollution, reduced fertility, contamination crops heavy metals, etc . Therefore, essential find alternatives promote sustainable agriculture ensure well-being people. Among alternatives, techniques that offer sustainable, environmentally friendly solutions reduce or eliminate inputs increasingly attracting attention researchers. One such alternative is beneficial microorganisms as plant growth-promoting rhizobacteria (PGPR). PGPR provides a variety ecological services can play an role yield enhancers biological control agents. They root development plants, increasing their capacity absorb water nutrients from soil, stress tolerance, disease development. Previous research highlighted benefits using PGPRs productivity. A thorough understanding mechanisms action exploitation biofertilizers would present promising prospect production, particularly maize cowpea, ensuring prosperous agriculture, while contributing security reducing impact chemical environment. Looking ahead, should continue deepen our crops, with view constantly improving practices. On other hand, farmers industry players need be made aware encouraged adopt them

Effects of Plant-Growth-Promoting Rhizobacteria (PGPR) and Cyanobacteria on Botanical Characteristics of Tomato (Solanum lycopersicon L.) Plants

Plants, Journal Year: 2022, Volume and Issue: 11(20), P. 2732 - 2732

Published: Oct. 15, 2022

Tomatoes are an important agricultural product because they contain high concentrations of bioactive substances, such as folate, ascorbate, polyphenols, and carotenoids, well many other essential elements. As a result, tomatoes thought to be extremely beneficial human health. Chemical fertilizers insecticides routinely utilized maximize tomato production. In this context, microbial inoculations, particularly those containing PGPR, may in place chemical pesticides. study, we investigated the effects PGPR (Bacillus subtilis, Bacillus amyloliquefaciens) cyanobacteria when alone, conjunction with each other, on growth, quality, yield fresh fruits plants. The results showed that inoculation significantly increased all measured parameters plants compared control. Combined use B. subtilis amyloliquefaciens had positive impact yield, increasing fruit yield. Moreover, leaflet anatomical characteristics were altered, thickness upper epidermis, lower palisade tissue, spongy vascular bundles. Tomato quality was improved, by number per plant (76% increase), weight (g; 33% height (cm; 50% diameter 50%), total soluble solids (TSS; 26% ascorbic acid (mg/100 g F.W.; 75% relative control, first season. addition, contents (N, P, K) inoculation. suggest could successfully used enhance growth

Management of abiotic stresses by microbiome-based engineering of the rhizosphere

Journal of Applied Microbiology, Journal Year: 2022, Volume and Issue: 133(2), P. 254 - 272

Published: March 30, 2022

Abstract Abiotic stresses detrimentally affect both plant and soil health, threatening food security in an ever-increasing world population. Sustainable agriculture is necessary to augment crop yield with simultaneous management of stresses. Limitations conventional bioinoculants have shifted the focus more effective alternatives. With realization potential rhizospheric microbiome engineering enhancing plant's fitness under stress, efforts accelerated this direction. Though still its infancy, microbiome-based has gained popularity because advantages over microbe-based approach. This review briefly presents major abiotic afflicting arable land, followed by introduction approach enhancement attributes stress mitigation inherent limitations. It then focuses on significance possibilities harnessing strategic for management. Further, success stories related two approaches (generation synthetic microbial community/consortium, host-mediated artificial selection) pertaining been critically presented. Together bringing forth challenges associated wide application agriculture, proposes adoption a combinational scheme same, together ecological reductionist improvised sustainable agricultural practices.

Microorganisms, Journal Year: 2024, Volume and Issue: 12(2), P. 398 - 398

Published: Feb. 17, 2024

This study tested the hypothesis that cocoa monoculture (MS) and cocoa-açai agroforestry systems (AFS) may influence microbial community structure populations of plant growth-promoting bacteria (PGPR). Accordingly, aim was to analyze PGPR in different agroecosystems Brazilian Amazon. To achieve this, rhizosphere açai plants both Amazonian seasons (dry rainy) analyzed using culture-dependent (PGPR screening) -independent methods [PCR-DGGE based on rrs, alp, nifH gene, intergenic region (ITS) fungi]. Concerning screening, out 48 isolated bacterial strains, 25% were capable siderophore production, 29% mineralized organic phosphate, 8% inorganic phosphate solubilization, 4% indole acetic acid production. Moreover, 17% isolates could inhibit growth various phytopathogenic fungi. Statistical analyses DGGE fingerprints (p < 0.05) showed fungal structures influenced by seasons, supporting results physicochemical analysis environment. Furthermore, as hypothesized, communities differed statistically when comparing MS AFS. These findings provide important insights into climate cultivation soil guide development sustainable agricultural practices.
