Summary: This study evaluated the effects of wheat straw biochar on disease development, plant physiology, and proteomic expression in tomato plants infected with Ralstonia solanacearum. The results showed that biochar application improved plant growth, reduced disease severity, and decreased the colonization of R. solanacearum in tomato stems. Physiological analysis revealed that biochar treatment increased peroxidase and lipoxygenase activities, as well as the content of total soluble phenolics and lignin-like phenolic polymers in tomato leaves. Proteomic analysis showed that biochar treatment upregulated genes involved in lignin synthesis, anion channel and sulfur metabolism, and downregulated genes involved in microtubule and cytoskeleton organization, as well as UDP-glucose metabolism.

Summary: Soil microbial communities play a crucial role in ecosystem functions, but understanding the complex nature of the microbial world and leveraging positive interactions for environmental benefits remains challenging. In this study, we investigated soil bacterial communities in healthy and diseased tomatoes and found that disease samples had higher abundance of a pathogen and lower bacterial diversity. Healthy tomato rhizosphere harbored more plant-beneficial microbes and had a more complicated co-occurrence network, suggesting better adaptability to soil-borne pathogen invasion. Community assembly analysis showed that the healthy rhizosphere communities were less phylogenetically clustered and mainly driven by dispersal limitation, while the diseased rhizosphere communities were primarily shaped by homogeneous selection. These findings highlight the importance of soil bacterial community composition and assembly in responding to soil-borne pathogen invasion.

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: Siderophores secreted by microorganisms can promote ecological efficiency and regulate the unbalanced microbial community structure. This study investigated the effect of siderophore activity from Trichoderma yunnanense strain 2-14F2 and Beauveria pseudobassiana strain 2-8F2 on soil enzyme activities, microbial metabolism, and community structure affected by tobacco bacterial wilt (TBW). The findings showed that these siderophores could significantly increase enzyme activities and carbon source utilization capacity of the microbial community in TBW soil, and have an impact on the composition and diversity of the microbial community.

Summary: Synthetic chemical pesticides pose major health and environmental hazards, but using biocontrol microbes and their bioactive compounds provides a safe and sustainable approach to plant protection. This study identified a furoic acid compound from Aspergillus niger that exhibits strong antibacterial activity against a soil-borne phytopathogenic bacterium. The compound enhanced host resistance, reduced bacterial population, and decreased disease severity in tomato plants.

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 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: 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 review introduces the techniques and mechanisms of bacteria immobilization on biochar, as well as its applications in bioremediation and agriculture. The immobilization characteristics of biochar depend on pyrolysis methods, raw materials, and properties of biochar. Scanning electron microscope and colony forming unit analysis are commonly used to verify the immobilization efficiency. Applying biochar-immobilized bacteria can improve soil quality, plant growth, and crop yield.
