QQ activity was confirmed by the loss of violacein pigment in <em>Chromobacterium violaceum</em> (MCC 2290). Quorum quenching metabolites were extracted using ethyl acetate, and the Quorum Quenching Extract (QQE) demonstrated positive activity in assays with <em>C. violaceum</em> CV026 (MCC 2216). HRLC-MS analysis identified diketopiperazines, L,L-Cyclo (leucylprolyl) and Cyclo (L-Phe-L-Pro), which are N-acyl homoserine lactones (AHLs) antagonists competing for LuxR receptor binding sites. In vitro and <em>in planta</em> assays evaluated QQB's biocontrol potential using treatment I (<em>Pcc</em>), treatment II (<em>Pcc</em> + QQB), and a control (sterile water). In the in vitro soft rot attenuation assay showed that treatment I caused severe maceration in vegetable slices, particularly in radish, exhibiting the highest maceration diameter (25.33 ± 3.52 mm) and percentage (46.14 ± 5.70 %). However, co-inoculation with QQB significantly reduced maceration across all tested vegetables. In the plate assay, germination rates decreased to approximately 50 % in both <em>Vigna radiata</em> and <em>Raphanus sativus</em> for treatment I, but improved to 86.67 % in treatment II. The seed vigour and germination indices also improved with QQB treatment in both plant species. In the pot assay after 30 days, in contrast to a 50 % decrease in root and shoot lengths in treatment I, treatment II led to a substantial recovery, with root lengths increase by 112.07 % and 138.76 %, while shoot length by 315.65 % and 163.63 % in <em>V. radiata</em> and <em>R. sativus</em>, respectively.

Shrubby mycorrhizal fungi (AMF), an important genetic resource of tropical soils, have a high potential for agricultural production, generally used as inoculant medium that provides better yield, productivity and physiological response to crops. This research study explores the presence of AMF in a botanical garden, composed of four areas: cactarium collection, epiphytes and ornamental collection, tropical forest area and coastal zone. Each area is composed of plants representative of its ecosystem. For the study, a random systematic model was used, with nine samples per site at a depth of 20 cm. A physicochemical characterization of the soils was developed. The extraction of AMF spores was carried out by wet sieving and centrifugation in 60% sucrose. The spores were identified by taxon. The results indicate a total of 379 AMF spores identified in the study area. The highest spore incidence was recorded in the tropical forest area with a total of 161 (53.67±5.51) spores extracted, followed by the coastal zone and cactus collection area with 78 (26.00±9.64) and 73 (24.33±4.73) spores in total. In the study two taxa were identified, Glomeraceae and Gigasporaceae. The taxon Glomeraceae is also considered to be the most representative (highest abundance and frequency) of the study. In conclusion, botanical gardens, by their extructure (plant composition) and management can be taken into account as important ecosystems reservoirs and source of viable microbial genetic material for the bioprospecting of beneficial soil genotic resources (rhizophiles and endophylls) for use in modern agriculture and sustainable food production systems.</div></div>","PeriodicalId":34305,"journal":{"name":"Current Research in Microbial Sciences","volume":"7 ","pages":"Article 100320"},"PeriodicalIF":4.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142721803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent clinical scenarios, AGS, including this species, have frequently been isolated from infections and disorders beyond those in the oral cavity. Consequently, investigating this situation will reveal the potential pathogenicity of AGS to ectopic infections in humans. However, the precise mechanism underlying the cellular response induced by secreted SLS and its relevance to the pathogenicity of AGS strains remain largely unknown.

In THP-1 cells incubated with the culture supernatant of β-hemolytic SAA containing SLS as the sole cytotoxic factor, increased Ca²⁺ influx and elevated expression of proinflammatory cytokines were observed. Significantly reduced expression of SLS-dependent upregulated cytokine genes under Ca²⁺-chelating conditions suggests that Ca²⁺ influx triggers SLS-dependent cellular responses. Furthermore, SLS-dependent enhanced expression of IL-8 was also implicated in the activation of extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (MAPK) signaling pathways.
