Comments P.2 left column top paragraph: "For [motility], A. tumefaciens produces a small tuft of up to 6 flagella that are typically localized at or around a single pole of the cell (primary source). Only the flagella-mediated swimming motility is recognized to occur in A. tumefaciens and there is no evidence of alternate motility mechanisms occurring in this bacterium (Mohari et al., 2015). The flagella in A. tumefaciens rotate clockwise to propel the bacterial cells forward. In contrast to the E. coli paradigm, tumbling in A. tumefaciens is thought to occur due to asynchronous slowing of flagellar rotation, resulting in disruption of the flagellar bundle, rather than a reversal of flagellar rotation (Merritt et al., 2007 Tomlinson and Fuqua, 2009)."
