The dimorphic bacterium Caulobacter crescentus provides a simple model for cellular differentiation. Each cell division produces two distinct cell types: a swarmer cell and a stalked cell. These cells possess distinet functional morphologies and differential programs of transeription and DNA replication. The synthesis of a single polar flagellum is(More)
The genes involved in the biogenesis of the flagellum and the chemotaxis machinery are temporally regulated during the Caulobacter crescentus cell cycle. Using plasmid complementation, we have mapped the extent of the flaY and flaE genes. These genes function in trans to regulate the expression of the flagellin genes and the chemotaxis genes. We have found(More)
