Abstract:
We show that exceedingly small two-dimensional slugs of Dictyostelium differentiate normally and have an anterior prestalk zone and a posterior prespore zone. Using GFP as a marker attached to the appropriate promoter, prestalk expression is concentrated in the anterior, while prespore expression is produced in the posterior, closely resembling what is found in normal, large slugs.
