Soil microorganisms, highly sensitive to environmental changes, adapt accordingly. This study focused on four areas of the Burdai coal mine: a non-subsidence area (CK), half-yearly (HY), 1-year (OY), and 2-year (TY) subsidence areas. Using high-throughput sequencing and molecular ecological network analysis, we examined soil microbial community diversity and structure across these zones, exploring microbial community assembly and functional predictions. Results showed that compared to the control, subsidence areas experienced reduced soil water content, organic matter, available phosphorus, and alkaline nitrogen, with the lowest levels observed at 1 year. These values began to rise after 1 year, suggesting natural recovery after subsidence stabilized. Microbial communities were closely related to soil organic matter, water content, and alkaline nitrogen. At the 1-year mark, soil property changes significantly reduced microbial diversity, which then began to recover after 2 years. The microbial network during 1-year subsidence was simpler, with 102 nodes, 179 edges, and an average degree of 3.51, indicating that early subsidence was unstable, and the microbial community was still adapting. By 1 year, community structure and interactions had begun to stabilize. Stochastic processes played a key role in microbial variability during short-term subsidence.","PeriodicalId":15101,"journal":{"name":"Journal of Basic Microbiology","volume":" ","pages":"e70002"},"PeriodicalIF":3.5,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143065828","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In protozoa, MCA plays an important role in programmed cell death (PCD). In Trichomonas vaginalis, a kind of PCD that resembles apoptosis has been described, but the activators of this mechanism have not been demonstrated. We performed a genome-wide in silico analysis in the T. vaginalis database using consensus MCA domains. A total of 15 protein annotations for MCA-like sequences were retrieved. Only 7/15 (TvMCA1-6 and TvMCA9) of the sequences were annotated as putative MCA and exhibited a similar range of amino acid length in comparison to the consensus sequences used for the query. By in silico analysis, we found that they are thermostable, hydrophilic proteins with molecular weights ranging from 27 to 33 KDa and their theoretical isoelectric points are in a 5.08-8.57 range. The phylogenetic analysis showed the similarity of conserved motifs for the predicted TvMCA proteins. 3D structure prediction by homology modeling demonstrated that TvMCA proteins show a similar conformation to crystallized MCA proteins. Taken together, our results indicate that these trichomonad proteins have conserved sequences like MCA proteins and suggest that they may be responsible for proteolytic activity during a PCD-like mechanism in this parasite.","PeriodicalId":15101,"journal":{"name":"Journal of Basic Microbiology","volume":" ","pages":"e2400786"},"PeriodicalIF":3.5,"publicationDate":"2025-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143046865","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A conventional chemotherapy approach to these pathogens has numerous environmental issues, while biological control agents (BCAs) are less promising under field conditions.

Simulation of BCA metabolites to nanoparticle biocontrol metabolites is considered the most effective biocontrol approach. Combining Fe2O3 nanoparticles and Trichoderma in nursery and field conditions manages pathogens and increases plant growth characteristics. The present study evaluated the commercial biocontrol strains and the use of NPFe in combination with Trichoderma harzianum to enhance the biocontrol potential of T. harzianum against soil-borne pathogens. The effectiveness of (NPFe + T. harzianum) was evaluated under in vitro conditions where combination was found most effective upto (87.63%) mycelial growth inhibition of pathogen and under field conditions lowest pooled Fusarium wilt incidence (19.54%) was recorded.
