The primary objective is to conduct a study on the morphoplasticity of eight accessions collected from diverse locations and categorized into three distinct biotypes based on floral pigmentation: Biotype 1 (White; accessions 1, 4, and 7), Biotype 2 (Pale Pink; accessions 2, 5, and 8), and Biotype 3 (Pink; accessions 3 and 6) of Convolvulus arvensis L. Based on the aforementioned characteristics-flower colour, stem outline, leaf shape, pollen features, shape, colpus and pori shapes, epidermal cell shape, and the number of vascular bundles in both stem and petiole-the study employed morphological and anatomical studies, as well as CDDP markers, to evaluate differences among accessions. Leaf tissues are parenchyma above the main vascular bundle, with an angle between the midrib and the wing region. Three distinct biotypes (B1, B2, and B3) have been defined. CDDP marker analysis revealed high polymorphism (74.36%) and Rp (9.50). Samples 7 and 8 (location 3) showed the most informative polymorphism of flower color (white/pale pink/pink). Genetic distances clustered samples primarily by location rather than by color, underscoring the dominant role of location in structuring populations. The interaction between genotype and ecological conditions led to the genetic variation in flower color in C. arvensis.</p>","PeriodicalId":8905,"journal":{"name":"BMC Biotechnology","volume":"26 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13615628/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149057917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, infections associated with antibiotic-resistant VISA isolates have increasingly posed life-threatening risks. Accordingly, there is an urgent necessity to investigate and develop efficient strategies against the rapid spread of VISA strains in the healthcare system. In this research, a niosomal drug delivery system was developed using the thin-film hydration method and then surface‑modified with polyethylene glycol (PEG). Teicoplanin (TEC) was further incorporated into PEGylated niosome (TEC-PEGylated niosome), and key physicochemical properties, including encapsulation efficiency (EE %), drug release profile, particle size, surface zeta charge, morphology, polydispersity index (PDI), and 30-day stability were measured. The antimicrobial potential of TEC-PEGylated niosome against five VISA strains isolated from burn wounds was investigated by determining the minimum inhibitory/bactericidal concentrations (MIC, MBC) and the time-kill assay. Furthermore, the anti-biofilm properties of the synthesized niosomal formulation were evaluated with a microtiter-plate (MTP) method and compared to those of free drug. FE-SEM results revealed that the niosomal formulation had spherical morphology with an approximate size of 250 nm. Hydrodynamic size, surface zeta charge, and EE% of the formulated niosomes were found be 278.8 ± 5.0 nm, + 9.5 ± 3.4 mV, and 65.9% ± 1.6, respectively. Also, TEC-PEGylated niosome demonstrated a significantly improved antibacterial ability compared to free drug. Additionally, TEC-PEGylated niosome effectively inhibited the biofilm formation capacity in all VISA strains. It was concluded that synthesized niosomal system could be an effective drug delivery system owing to several advantageous characteristics, including sustained-release profiles, acceptable stability, and other desirable features. These properties enable PEGylated niosomes to effectively deliver a diverse array of antimicrobial agents, including TEC. This capability could present a promising novel strategy for addressing burn infections, particularly those caused by VISA strains.</p>","PeriodicalId":8905,"journal":{"name":"BMC Biotechnology","volume":" ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13663312/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148418163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
