Summary: Bacteriophage phi sp1 isolated in this study was highly host specific, effective in biofilm prevention, and capable of inhibiting bacterial wilt at low multiplicity of infection (1.0 MOI) in tomato and potato tuber bioassays. The phages showed environmental stability, surviving variable pH and temperature, suggesting their potential for biocontrol formulation against R. solanacearum bacterial wilt disease.

Summary: Bacterial wilt caused by Ralstonia solanacearum is a growing concern in amaranth production in Benin. Host resistance is identified as the most sustainable disease control measure. The study suggests that the UG-AMES13-2 variety from the World Vegetable Center shows high resistance to R. solanacearum and should be promoted for seed production to support farmers.

Summary: This study systematically analysed the infection of R. solanacearum in S. dulcamara, showing that bittersweet plants exhibit partial resistance to bacterial wilt compared with susceptible hosts like tomatoes, especially at lower temperatures. The findings suggest that inherent resistance and perennial growth habits enable bittersweet plants to act as reservoirs for the pathogen.

Summary: In this study, the changes in rhizobacteria, endobacteria, and root exudates during the pathogenesis of bacterial wilt in ginger caused by Ralstonia solanacearum (Rs) were analyzed using high-throughput sequencing and gas chromatography-mass spectrometry (GC-MS). The results showed that Rs infection led to a 50.00% incidence of bacterial wilt in ginger and altered the composition of bacterial communities in both the endosphere and rhizosphere. Furthermore, the changes in rhizobacterial composition induced corresponding changes in endobacterial and root exudate compositions. The upregulated exudates inhibited ginger bacterial wilt, indicating that ginger produces antibacterial compounds as a defense mechanism against bacterial pathogens.

Summary: Plant and soil-associated microbiome play a crucial role in conferring tolerance to bacterial wilt disease in plants. Ralstonia solanacearum (RS), the causative agent of bacterial wilt, colonizes the xylem vessels and restricts water supply, leading to wilting. This review highlights the dynamics of microbiome associated with bacterial wilt disease and provides an update on microbial and non-microbial approaches utilized for disease control in crop plants.

Summary: This study investigates the influence of rhizosphere phage communities on soil suppressiveness and bacterial wilt disease. It shows that healthy plants are associated with phage communities that have stronger control over the pathogen R. solanacearum. Additionally, phages that target pathogen-inhibiting bacteria are more abundant in diseased plant microbiomes. These findings suggest that rhizosphere phage communities play a crucial role in determining bacterial wilt disease outcomes and soil suppressiveness.

Summary: The study investigated the antibacterial activities of novel plant-derived coumarins against Ralstonia solanacearum and found that 6-methylcoumarin exhibited the best in vitro antibacterial activity. It was shown to affect cell morphology, disrupt cell division, and suppress the expression of bacterial division protein coding genes ftsZ. The application of 6-methylcoumarin effectively suppressed the development of tobacco bacterial wilt in pot and field experiments, demonstrating its potential as an eco-friendly and target-specific agent for disease control.

Summary: This study demonstrates the positive impact of M. salsuginis TNMB03 biotization on the growth and survival of tissue culture banana plantlets in both greenhouse and open environmental conditions. Plantlets biotized with M. salsuginis TNMB03 showed better acclimatization response, increased growth parameters, and improved chlorophyll content compared to uninoculated plantlets. The inoculation of M. salsuginis TNMB03 presents a potential technique for enhancing plantlet growth without the need for traditional acclimatization procedures.

Summary: The rapid increase in soil salinization threatens agricultural output and food security. Improving soil fertility and agricultural yield is crucial, as abiotic factors like soil salinity have rendered a third of land unproductive. Microbes play a key role in addressing agricultural challenges, particularly in communication and stress reduction between plants and beneficial microbes. Proteins and metabolites synthesized by bacteria and plants have important roles in plant stress tolerance, and their genomic, proteomic, and metabolomic characterization aids in increasing crop output.
