In addition, transgenic N. benthamiana (Hahn-Löbmann et al., 2019) and N. tabacum L. plants expressing ColM were developed (Łojewska et al., 2020) and the antibacterial activity of purified ColM obtained from these plants was confirmed against an array of pathogenic strains, including clinical isolates of E. coli and Klebsiella pneumonia. Here, GLDN is linked to Klebsiella pneumonia.
