Bacterial wilt, caused by Ralstonia solanacearum , is one of the most destructive diseases of tomato, with biovar 3 race 1 isolates predominant in India. The present study investigated rhizosphere bacterial isolates (ToRB-1 to ToRB-45) for their antagonistic potential against a virulent R. solanacearum isolate Rs-TN-02. Among these, the cell-free supernatants of isolates ToRB-7, ToRB-23, and ToRB-26 exhibited greater inhibition in agar diffusion assays. Molecular characterization using 16S rRNA and DNA gyrase genes identified these isolates as Bacillus velezensis . Chemical profiling using gas chromatography–mass spectrometry revealed the presence of several secondary metabolites, and selected compounds were subjected to in silico docking analysis with virulence-related proteins of R. solanacearum . Scanning electron microscopy of co-cultured broth indicated the predominance of B. velezensis cells and observable morphological alterations in Rs-TN-02. Under in vitro conditions, the isolates demonstrated multiple plant growth-promoting traits, including IAA, ammonia, HCN, and siderophore production, as well as phosphorus and zinc solubilization. In a glasshouse experiment, their combined application enhanced seed germination (97.33%), shoot length (37.9 cm) and root length (15.6 cm), and reduced bacterial wilt incidence by 88.13% compared with the untreated control. Treated plants showed enhanced defence enzyme activities and total phenol content. RT-qPCR analysis of selected defence-related genes indicated a positive transcriptional response with a 3.6-fold increase in NPR-1 expression. Overall, the study highlights the antagonistic, plant growth-promoting, and disease-suppressive attributes of B. velezensis isolates under controlled experimental conditions, supporting their potential inclusion in integrated and sustainable management strategies for tomato bacterial wilt, pending further field-level validation. • Bacillus velezensis isolates suppressed Ralstonia solanacearum Rs-TN-02 under in vitro conditions. • Co-culturing resulted in growth suppression and cellular alterations of Rs-TN-02 as observed by scanning electron microscopy. • B. velezensis exhibited hydrolytic enzyme activities and plant growth-promoting traits in vitro. • Combined application of B. velezensis isolates improved tomato growth and reduced wilt incidence under controlled conditions. • Defence enzyme activities and defence-related gene expression were enhanced following B. velezensis treatment.

Microbial Pathogenesis, 2026
Dry root rot caused by Macrophomina phaseolina is the most destructive soil-borne fungal disease that severely hampers groundnut production. This study investigated the multifaceted biocontrol and plant growth-promoting potential of rhizospheric Streptomyces spp., focusing on the strain Streptomyces clavuligerus GRS-8. In vitro dual culture assays revealed that GRS-8 exhibited the highest antifungal activity, inhibiting 76.50 % of M. phaseolina mycelial growth. The strain also produced key metabolites, including indole-3-acetic acid, siderophores, and hydrolytic enzymes, contributing to plant growth promotion and defense priming. In silico molecular docking identified quininone oxime as a potent bioactive compound with high binding affinity to five virulence-associated proteins of M. phaseolina. Molecular dynamics simulations confirmed the structural stability of the lipase-quininone oxime complex, supporting its potential as a fungal inhibitor. Under protected cultivation, the combined application of GRS-8 liquid formulation via seed treatment, basal application, and soil drenching significantly reduced dry root rot incidence by 73.10 % and enhanced the activity of host defense enzymes. These findings highlight the dualistic mechanism of S. clavuligerus GRS-8 involving direct antifungal action and host defense induction, underscoring its potential as a promising biocontrol agent for sustainable groundnut cultivation.

Actinobacteria are a source of prolific antimicrobial compounds with broad-spectrum biocontrol potential against phytopathogens. This review elucidates the antagonistic mechanisms of actinobacteria and highlights their antimicrobial activities through an integrated omics approach that encompasses genomics, transcriptomics, proteomics, and metabolomics. Genomic mining has revealed diverse biosynthesis-related gene clusters responsible for the production of secondary metabolites such as polyketides, non-ribosomal peptides, siderophores, and volatile organic compounds. Transcriptomic analysis demonstrated the ability of actinobacteria especially Streptomycetes spp. to modulate host defense gene expression and suppress pathogen virulence factors. Metabolomic technology has identified novel bioactive compounds using Liquid Chromatography –Mass Spectrometry/ Mass-Spectrometry, whereas proteomics has enabled functional profiling of defense-related proteins, including polyketide synthases, chitinases, polyene macrolides, phenazine and regulatory proteins that disrupt the fungal membranes. Integration of omics strategies increases our knowledge of actinobacterial biocontrol mechanisms and facilitates the identification of effective strains to combat destructive phytopathogens. Unveiling microbial interactions and metabolite pathways through a multi-omics approach hastens the development of eco-friendly bioformulation(s). This review also highlights recent insights into actinobacteria-mediated plant disease management, and identification of antagonistic mechanisms of actinobacteria at the molecular level, and emphasizes the value of omics-driven discovery to develop eco-friendly formulations to combat the phytopathogens. • Comprehensive overview of actinobacteria as plant growth-promoting and biocontrol agents in sustainable agriculture. • Integrated multi-omics approaches connect genetic potential to metabolite production, elucidating molecular mechanisms of pathogen inhibition. • Case studies demonstrate successful omics-guided discovery of potent Streptomyces strains and metabolites.

This study investigates the effects of commercially available entomopathogenic fungal formulations on the Indian honey bee Apis cerana indica Fabricius (Hymenoptera: Apidae). A 10-day bioassay conducted under laboratory conditions used four methods (topical, spray, leaf dip, feeding) to evaluate the pathogenicity of Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Cordycipitaceae), Beauveria brongniartii (Sacc.) Petch (Hypocreales: Cordycipitaceae), Metarhizium sp. (Metschnikoff) Sorokin (Hypocreales: Clavicipitaceae), and Lecanicillium sp. (Zimmermann) Zare & Gams (Hypocreales: Cordycipitaceae) on A. cerana indica at 5 × 108 conidia/ml. After exposure to fungal formulations via different methods, we recorded conidial acquisition by bees (4.36 × 104 – 21.08 × 104 conidia/bee). The mortality rates were significantly lower in the topical (6.58%), leaf dip (10.17%), spray (9.92%), and feeding (9.17%) exposure methods, indicating their nontoxicity (< 25% mortality) according to IOBC classification. Among the fungal formulations tested, Lecanicillium (93.25%) recorded significantly higher survival rates. Mycosis percentage (3.66 – 15%) was observed in the 10-day-old moribund bees. The lethal time (LT) estimates, viz., LT10 and LT25, were comparatively lower in the topical exposure method (LT10: 13.4 – 16.08 days, LT25: 17.08 – 19.68 days). However, the effects of entomopathogenic fungal formulations must be further confirmed under field conditions.

Physiological and Molecular Plant Pathology, 2025
The rhizosphere, phyllosphere and endosphere of plants are a collection of microorganisms simply called as the plant microbiome, essential to the health and protection of plants. Responses of plants to soil-borne diseases, which cause large-scale agricultural losses worldwide, are significantly impacted by this microbiome. According to recent study, there is a chance to confront these infections by using plant-associated microbiomes as an environmentally beneficial substitute for current chemical control methods. Examining the state of plant microbiome research in relation to managing soil-borne pathogens, this review highlights important discoveries and developments. It investigates the processes such as resource competition, antimicrobial synthesis, and stimulation of plant defense responses by which advantageous microorganisms give plants resistance. Notwithstanding encouraging outcomes, a number of obstacles stand in the way of using microbiome-based treatments in practical applications. These include the complicated nature of the relationships between microbes, the variation in the structure of the microbiome in various soils and environments, and the requirement for scalable and reliable application techniques. In order to overcome these obstacles, future studies must improve our knowledge of the dynamics of microbial communities, make use of cutting-edge genomic and metagenomic technologies, and combine sustainable farming methods with microbiome management techniques. This all encompassing strategy could transform disease control and improve food security worldwide.
