Endocytosis-like DNA uptake by cell wall-deficient bacteria

Nature Communications, 2022
Horizontal gene transfer in bacteria can occur through mechanisms such as conjugation, transduction and transformation, which facilitate the passage of DNA across the cell wall. Here, Kapteijn et al. show that cell wall-deficient bacteria can take up DNA
