Abstract/OtherAbstract:
We describe the isolation of staB, a Dictyostelium gene that is selectively expressed in stalk cells. If an aggregate enters culmination immediately staB is expressed in the bottom half of the stalk and in the basal disc but if a migratory slug is formed it is also expressed in the top of the stalk and in a disc of cells that surmounts the spore head. The latter two populations of cells derive from the rear part of the prestalk region, the pstO cells, which would therefore seem to change their transcriptional competency during slug migration. The staB promoter contains a distal region that is required for expression within both the stalk and the basal disc and a proximal region that is required only for expression within the basal disc. This uncoupling of transcriptional specificities suggests that the signalling mechanisms that direct terminal differentiation in these two tissues differ in some way.
