Horizontal gene transfer (HGT) has been proven to have a much stronger impact than mutation in the microbial world. Evidence of HGT is currently expressed as comparative sequence homology, whereas a substance with residing transfer initiative remains ambiguous. The simultaneous transfer of multiple genes could have more profound impacts than single-gene exchange on the evolutionary processes, but such data are still insufficient. Although three novel modes of HGT mechanisms have come to light—gene transfer agents (GTAs), membrane vesicles (MVs), and intercellular nanotubes (Ins)—the classic concepts of transformation, transduction, and conjugation must not be ignored. |
