Holdfast formation in motile swarmer cells optimizes surface attachment during Caulobacter crescentus development.
The adhesive holdfast is required for irreversible surface anchoring of Caulobacter crescentus cells. The holdfast is synthesized early during swarmer cell development and, together with pili and a functional flagellum, contributes to optimal attachment during cell differentiation. We present evidence that the timing of holdfast formation in swarmer cells is regulated posttranslationally and is dependent on the diguanylate cyclase PleD.
