consequently , we propose that the steps required for formation of swarmer cells and subsequent development into stalked cells are organized into at least two developmental pathways : a plea-dependent sequence of events , responsible for flagellum biosynthesis in predivisional cells , and a plec-pled-dependent sequence , responsible for flagellum activation in predivisional cells and loss of motility and stalk formation in progeny swarmer cells .
