TL;DR
Indigenous bacterial and archaeal communities in agricultural soils were analyzed to provide a basis for biocontrol and bioremediation solutions to be reintroduced in affected areas and showed in vitro the most promising combination of PGP traits, metal tolerance, and antifungal activity against most phytopathogenic fungi.
Bacterial diversity was lower in the rhizosphere, which was characterized by a distinct taxonomic composition, including taxa such as Promicromonospora and Nocardioides potentially involved in nutrient cycling and stress adaptation.

The increasing demand for food has driven intensive agricultural practices, which negatively impact soil health and ecosystem stability; therefore, it is necessary to adopt sustainable alternatives that enhance crop productivity while minimizing environmental damage. The aim of this study was to characterize the bacterial and fungal microbiota present in bioinputs derived from mountain soil microorganisms used in maize cultivation, as well as the microbial communities in agricultural soils at the end of the cultivation stage across different plots in the Frailesca region, Chiapas, Mexico. Bacterial communities showed differences among bioinputs depending on their origin, while soil samples showed relatively similar bacterial distribution patterns across plots. Conversely, fungal communities displayed heterogeneous distribution patterns in both bioinputs and soils. Several microbial groups related to beneficial functions for plants and soil, such as nitrogen fixation, phosphate solubilization, and the production of phytohormones and siderophores were identified; those belonging to the genera Acetobacter, Klebsiella, Meyerozyma, Saccharomyces, and Paecilomyces were found in bioinputs, while those belonging to the genera Bradyrhizobium, Sphingomonas, Penicillium, Talaromyces, Humicola, and Metarhizium were identified in soil samples. The results demonstrate that bioinputs contain microbial communities with potential plant growth-promoting functions and can serve as strategies for improving soil health through sustainable agricultural production.

Western ghats in India, one of the world’s biodiversity hot spots is the reservoirs of microbial resources having agricultural and industrial significance. However, the diversity of plant growth-promoting microbial communities associated with the plants and soil in the Western Ghats is untapped vault. The current emphasis on natural farming is more depending on the indigenous microbial communities and their metabolic functions towards sustainable one -health. With this background, the present study examines the bacterial diversity of soils from the Western Ghats of Nilgiris, Coimbatore and Dindigul regions. Among the 10 soil samples collected (S1 to S10), three soil samples (S2, S4 and S6) representing respective three regions were subjected for metagenomic studies based on their distinct soil chemical and biological properties. The computational analysis of the metagenome revealed the core genus
Bradhyrhizobium
in all soil samples, while
Trebonia
,
Arthrobacter, Streptomyces,
and
Pseudomonas
are the next most abundant genera, which varied substantially. The results collectively demonstrate that soil sample from Dindigul harbours the richest and most diverse microbial community among the three regions. In culturable studies, a total of 101 bacterial isolates were obtained from 10 soil samples (S1 to S10). Among them four Gram-negative bacterial isolates showed potential plant growth-promoting attributes, such as Ammonia, Indole Acetic Acid, Hydrogen cyanide and siderophore production, phosphorus, potassium, and zinc solubilization. The 16S rDNA analysis revealed that the bacterial isolates were
Pseudomonas glycinae
S6B1,
Pseudomonas tolaasii
S2B3,
Pseudomonas azotoformans
S9H10, and
Pseudomonas poae
S10B2. The isolate, S10B2, exhibited the maximum inhibition, with 81.25%, 70.1%, and 35% against plant pathogenic fungi,
Rhizoctonia solani
,
Sclerotium rolfsii
, and
Fusarium oxysporum
, respectively, indicating strong biocontrol potential. The effect of bacterial inoculants on chick pea (
Cicer arietinum
var. JG 62), showed that
P. glycinae
S6B1 significantly promoted plant growth such as root length, shoot length, and fresh/dry biomass. These findings unlock the core microbiome of soils of Western Ghats, which can be utilized to develop a synthetic microbial consortium to boost agricultural productivity.

These distinct functional profiles demonstrates that the protected root endomicrobiome specializes in plant signalling and nutrient assimilation, while the rhizosphere microbiome, facing higher competition, specializes in nutrient acquisition and stress resilience.
