FIG. 1.
R. solanacearum motility in culture and in planta. Wild-type strain K60 cells were grown in BMM broth (open triangles) or extracted from midstem xylem vessels of infected tomato plants (closed circles). The percentage of motile cells was determined microscopically by counting motile and nonmotile cells on a hemocytometer slide. Cell density was confirmed by dilution plating in triplicate.
