Article Title: A plant-derived antimicrobial peptide with multiple mechanisms of action exhibiting antibacterial and antibiofilm activities comparable to or superior to polymyxin B

doi: 10.1016/j.crmicr.2025.100535

Figure Lengend Snippet: Membrane integrity or damage and morphology of E. coli following exposure to various concentrations of the NCR169C 17–38 peptide. (A) E. coli cells were stained with SYTO 9 and PI, and pictures were taken with confocal microscope; scale bar: 10 µm. (B) Cells were treated with the peptide in the absence of fluorescent dyes and imaged using a scanning electron microscope; scale bar: 1 µm. (C) Monitoring of PI uptake in E. coli treated with a series of concentrations of NCR169C 17–38 in Hidex Plate reader. RFU (535/616) = Relative Fluorescence Units (excitation/emission wavelengths). 0.8 µM Polymyxin B (PMB) was used as a control.

Article Snippet: The trimmed samples were aligned to the E. coli ATCC_8739 genome database using STAR ( ) as described by ( ; supplementary Table 37).

Figure Lengend Snippet: In vitro interaction of NCR169C 17–38 , NCR169, NCR169 16–27 and NCR169 17–27 with nucleic acids. (A) Gel retardation assay of 100 ng E. coli genomic DNA incubated with 0, 10, or 100 µM peptide. (B) Same setup as in (A), but using 100 ng E. coli total RNA. (C) Interaction of NCR169C 17–38 with 250 ng circular plasmid DNA at varying concentrations. (D) Real-time monitoring of DNA binding by fluorescence of SYBR Gold–DNA complexes (excitation 490 nm, emission 535 nm). Peptides (10 µM) were added to 100 ng DNA at 0 or 14 min (red arrows); Proteinase K (1 mg/mL) was added at 27 min (black arrow).
