“…Biosynthesis of IAA by PGPR stimulates the plant growth. Previous studies reported that various IAA producers (Pseudomonas and Bacillus) can promote lateral root growth with the IAA production of about 213.25 ± 1.32 μg ml −1 (Ansari and Ahmad, 2019;Baliyan et al, 2021). In the present study, the maximum IAA was found to be 103.82 ± 1.02 μg ml −1 by PSF1.…”

Plant Growth Promoting Rhizobacteria (PGPR), a microbial biostimulant has been widely studied to stimulate plant growth through induction of natural biological processes. However, lack of successful validation under open field remains a barrier to mark their standard in agriculture. Therefore, the aim of the research was to highlight the potential of PGPR biostimulants via in vitro studies and subsequently to demonstrate the in planta evaluation in oilseed crop, Arachis hypogaea L. (Groundnut) under pot and field trials. The two rhizobacterial strain was identified as Pseudomonas fluorescens and Bacillus subtilis by 16s rRNA gene sequence analysis. Both the strains were functionally screened for plant growth promoting traits. Pot and field trials were conducted where seeds were inoculated with PGPR biostimulants and harvested at 30 and 90 days. Biostimulant treatments were applied as single and co-inoculation in groundnut and the growth factors, biochemical parameters, yield, and seed quality were analyzed. The study inferred that the consortium of PGPR biostimulants significantly (p < 0.05) showed highest growth, photosynthetic pigments, nodulation status, leghaemoglobin content, yield attributes, and also biofortification of seed nutrients in oilseed crop under both pot and field conditions than un-inoculated control. This study supports the idea of the application of PGPR as microbial biostimulants through successful open field trial to facilitate its implementation as a feasible and potential agricultural product to synthetic fertilizers thereby influencing sustainable and stable crop production.

“…Similarly, phages also control the size and composition of these microbiomes (Koskella and Taylor 2018 , Gilbert et al 2020 , Holtappels et al 2023 ). The mechanisms of predation, be it via protozoan grazing or lysis by phages, represent an understudied but promising intervention tool to elicit benefits for the host including nutrient supply (Gao et al 2019 , Gilbert et al 2020 ) or biocontrol of pathogens (Chabé et al 2017 , Baliyan et al 2022 , Holtappels et al 2023 ).…”

Microbiomes are foundational components of the environment that provide essential services relating to food security, carbon sequestration, human health, and the overall well-being of ecosystems. Microbiota exert their effects primarily through complex interactions at interfaces with their plant, animal, and human hosts, as well as within the soil environment. This review aims to explore the ecological, evolutionary, and molecular processes governing the establishment and function of microbiome-host relationships, specifically at interfaces critical to One Health – a transdisciplinary framework that recognises that the health outcomes of people, animals, plants and the environment are tightly interconnected. Within the context of One Health, the core principles underpinning microbiome assembly will be discussed in detail, including biofilm formation, microbial recruitment strategies, mechanisms of microbial attachment, community succession and the effect these processes have on host function and health. Finally, this review will catalogue recent advances in microbiology and microbial ecology methods that can be used to profile microbial interfaces, with particular attention to multi-omic, advanced imaging, and modelling approaches. These technologies are essential for delineating the general and specific principles governing microbiome assembly and functions, mapping microbial interconnectivity across varying spatial and temporal scales, and for the establishment of predictive frameworks that will guide the development of targeted microbiome-interventions to deliver One Health outcomes.

“…Atroseptica ), responsible for potato tuber rot [ 177 ]. However, nowadays, the indiscriminate use of antibiotics, chemicals, and copper-based formulations as antibacterial treatments for crops has led to the development of resistant phytopathogen bacterial strains, and, in addition, the continuous use of these substances is highly harmful to the environment [ 177 , 178 , 179 ].…”

This review aims at presenting the main strategies that are currently available for the delivery of bacteriophages to combat bacterial infections in humans, animals, and plants. It can be seen that the main routes for phage delivery are topical, oral, systemic, and airways for humans. In animals, the topical and oral routes are the most used. To combat infections in plant species, spraying the plant’s phyllosphere or drenching the soil are the most commonly used methods. In both phage therapy and biocontrol using phages, very promising results have been obtained so far. However, more experiments are needed to establish forms of treatment and phage doses, among other parameters. Furthermore, in general, there is a lack of specific standards for the use of phages to combat bacterial infections.
