Summary: The research revealed that the invasion of F. oxysporum had a significant impact on the endophytic microbiota communities, particularly showing a reduction in the abundance of Bacillus sp. which are crucial for suppressing F. oxysporum. This suggests that monitoring the dynamics of endophytic bacteria communities and pathogen densities could lead to more accurate disease diagnostics and efficient screening methods for plant pathogens.

Summary: By sequencing the soil microbial diversity in six main banana-producing areas in Yunnan, this study found that Chujaibacter, Bacillus, and Sphingomonas were significantly enriched. Further correlation analysis revealed a significant negative correlation between Bacillus and the soil pathogen Foc TR4. Thus, a B. velezensis strain YN1910 was isolated from disease-suppressive soils, which showed significant control (78.43-81.76%) of banana Fusarium wilt and significant growth promotion on banana plants in vitro and pot experiments.

Summary: By analyzing the composition and functional potentials of soil microbiomes, this study identified specific microbial communities and genes associated with the suppression of banana Panama disease caused by Fusarium oxysporum f. sp. cubense tropical race 4 (Foc4). Pseudomonas was identified as a potential key taxon linked to pathogen suppression, and the microbiomes in suppressive soils displayed a greater incidence of genes related to quorum sensing, biofilm formation, and synthesis of antimicrobial compounds. These findings suggest the importance of specific microbial communities and functional capacities in disease suppression.

Summary: This study used molecular techniques to analyze the bacterial communities in suppressive and conducive soils, finding higher diversity and species richness in the suppressive soil. The dominant phylogenetic groups in suppressive soil were Actinobacteria and Proteobacteria, while conducive soil had fewer Actinobacterial sequences and was dominated by Gamma- and Betaproteobacteria.

Summary: This study tracked the succession of Fusarium in steam-sterilized soil. The results indicated that although steam sterilization can temporarily eliminate Fusarium, its re-emergence may be exacerbated as the resident bacterial community is continuously depleted by the sterilization process, while Fusarium benefits from nutrients released by steaming.

Summary: This study found that the diversity of rhizosphere microbiota is negatively correlated with Fusarium wilt disease in tomato plants. Cross-kingdom SynComs showed the best suppression effect against the disease, providing a new effective strategy for controlling soil-borne diseases.

Summary: The large outbreak of banana Fusarium wilt has become a bottleneck to the industry's development. This study investigated the effects of pineapple-banana crop rotation and pineapple residue amendment on the soil microbial communities and disease incidence. The results showed that both rotation and residue addition significantly reduced disease incidence and altered the bacterial and fungal community composition.

Summary: Nematode-suppressive soils are characterized by microbial communities which can reduce populations of plant-parasitic nematodes. Different soil origins have a major effect on the composition of nematode-attached bacteria, with the highest bacterial abundance and richness observed in suppressive soils. Further research is needed to understand the complexity of nematode-microbial interactions and the exact role of nematode-attached microorganisms in nematode suppression and protection.

Summary: This study investigates the impact of long-term contamination on the soil microbiome composition and diversity at an urban brownfield in Los Angeles. The findings suggest that the presence of heavy metals and organic pollutants shape the soil microbiome diversity, and certain bacteria and fungi show tolerance to these contaminants. The study recommends incorporating DNA-based multi-marker microbial community profiling in brownfield site assessment and restoration.

Summary: Biochar plays a crucial role in the distribution and forms of soil phosphorus by impacting soil biochemical characteristics and microbial community. This study found that medium application rates of biochar led to the highest increase in bacterial diversity and abundances, as well as the retention of phosphorus forms in bacterial cells. At low application rates, the abundance of nitrogen-fixing and phosphorus solubilizing and mineralizing bacteria increased. However, at high application rates, the proportion of phosphorus retained in bacterial cells decreased while more stable forms of phosphorus steadily increased.

Summary: The study demonstrated that fumigation with dazomet followed by the application of biological organic fertilizer effectively suppressed Fusarium wilt disease incidence with a 93.6% control rate. Fumigation reduced soil microbial diversity and altered relative taxa abundances, while the addition of bio-fertilizer promoted interactions within the soil microbial community, leading to increased relative abundances of beneficial microbes and decreased presence of Fusarium.

Summary: This study provides the first detailed characterization of the microbiota and chemistry in different arid habitats of Qatar. The dominant microbial phyla were Actinobacteria, Proteobacteria, Firmicutes, Bacteroidetes, and Chloroflexi, though their abundances varied across soils. The study also found correlations between microbial diversity and soil characteristics such as sand, clay, and silt.
