“…Recent experiments have suggested that multiple nutrients such as nitrogen (N), phosphorus (P), zinc (Zn) etc. may be obtained in the rhizophagy cycle (21)(22)(23). Endophytes enhance the concentration of N and P in roots and shoots of endophyte-inoculated plants (24)(25)(26)(27).…”

Endophytes are ubiquitous and grow in plant tissues without causing any harmful effects to the host. They include different groups of microorganisms such as bacteria, fungi and actinomycetes. Along with the host plants, the existing endophytes also co-evolve after a long relationship between them. Host plant-endophyte interaction is similar to that of plant growth promoting microbes as they induce the growth of the host plant and increase resilience against biotic and abiotic stresses. The interaction of plant endophytes at the molecular level and the effect of endophytes on host gene expression is a new field of study and are still rarely explored. Endophytes act as a promising resource of many invaluable bioactive secondary metabolites. Some of these bioactive compounds include alkaloids, polyphenols, sterols, xanthones, terpenoids, flavones, coumarins, polyketides, quinones, saponins, tannins, benzopyrones, dibenzofurans. These secondary metabolites are beneficial for agriculture, industrial and pharmacological purposes. As endophytes have beneficial effects in sustainable agriculture, plant disease management, pharmaceuticals, industry and environmental management in an eco-friendly way, thus improving the strategy of application of endophytes as biological agents in every aspect of our life is a very challenging field of research. Our aim in this present review is to focus on plant-endophyte interactions and their various dimensions in order to address some future possibilities for expediting the bioactive secondary metabolite production.

“…Plant growth-promoting microbes can provide resistance against phytopathogens via the production of phytohormones and regulating nutritional balances in unfavorable stress conditions. Thus, plant-soil-microbes create a tripartite interaction environment that is controlled by the dominant interaction, such as plant-microbes, microbes-microbes, and microbes-plant interactions (Das et al 2022). The impact of soil microbes on human health can draw on the Fig.…”

Potential applications include using PGPR and PGPB as biofertilizers, biopesticides, and biocontrol agents instead of using chemical fertilizers to enhance crop productivity(Das et al 2022). Soil microbes can improve soil fertility by breaking down soil organic matter, recycling nutrients in the soil, and fixing nitrogen.…”

ECOGNITION of the links between soil and human health goes back thousands of years, when ancient people recognized the value of soil and its potential for human life. As a dynamic, complex, and open system soil consists of flora and fauna (microbes and others), water, air, and mineral and organic particles. These components of soil may cause negative (diseases, nutrient imbalances) and/or positive (supply of antibiotics, bioactives, secondary metabolites, or essential nutrients) impacts on human health. Soil microbes are a crucial component of the soil system that can cause human diseases or be used in the production of antibiotics and other drugs. There is still great need to study the soil microbial community, as new soil microbes are regularly discovered along with new compounds that are beneficial to human health, such as drugs, bioactives, and secondary metabolites. This mini-review discuses the potential of soil microbes, including their positive and negative influences within the soil-human health nexus. This work is unique in that it mainly depends on diagrammatic presentations, which can explain the target meaning in a very simple manner.

“…Soil microbial supplementation is influenced by root exudates that produce different enzymes and metabolites, nutrient accumulation, and hormone production ( Singh and Gupta, 2018 ; Zayed et al., 2022 ). Plant growth-promoting bacteria (PGPB) improve growth and can protect plants against biotic and abiotic stresses by producing volatile compounds, siderophores, growth hormones, biological nitrogen fixation, and reducing plant ethylene synthesis ( Khatoon et al., 2020 ; Das et al., 2022 ). Identifying the signaling pathways governing the associations between plants and different PGPB can play an important role in improving agricultural production sustainably ( Wiggins et al., 2022 ).…”

Seed Endophyte bacteria enhance drought stress tolerance in Hordeum vulgare by regulating, physiological characteristics, antioxidants and minerals uptake

Growth stimulating bacteria help remediate dry arid soil and plant stress. Here, Pseudomonas sp. and Pantoea sp. we used to study the stress ecology of Hordeum vulgare and the environmental impact of water deficit on soil characteristics, growth, photosynthesis apparatus, mineral acquisition and antioxidiant defense. Plants inoculated with Pseudomonas or Pantoea had significantly higher (about 2 folds) soil carbon flux (soil respiration), chlorophyll levels (18%), net photosynthetic rate (33% in Pantoea and 54% in Pseudomonas), (44%) stomatal conductance than uninoculated plants in stressed conditions. Both bacterial strains improved leaf growth (23-29%) and root development under well-watered conditions but reduced around (25%) root biomass under drought. Plants inoculated with Pseudomonas or Pantoea under drought also increased of about 27% leaf respiration and transpiration (48%) but decreased water use efficiency, photoinhibition (91%), and the risk of oxidative stress (ETR/A) (49%). Drought stress increased most of the studied antioxidant enzymatic activities in the plants inoculated with Pseudomonas or Pantoea, which reduce the membrane damage and protect plants form oxidative defenses. Drought stress increased K+ acquisition around 50% in both shoots inoculated with Pseudomonas or Pantoea relative to non-stressed plants. Plants inoculated with Pseudomonas or Pantoea increased shoot Na+ while root Na+ only increased in plants inoculated with Pseudomonas in stressed conditions. Drought stress increased shoot Mg2+ in plants inoculated with Pseudomonas or Pantoea but did not affect Ca2+ relative to non-stressed plants. Drought stress increased about 70% K+/Na+ ratio only in plants inoculated with Pseudomonas relative to non-stressed plants. Our results indicate that inoculating barley with the studied bacterial strains increases plant biomass and can therefore play a role in the environmental remediation of drylands for food production.
