Developmentally regulated gene expression. (A) Fluorescence microscopy of wild-type (Ax2) or detA− slugs transformed with the prestalk reporter [ecmAO]:GFP 17 h after the onset of starvation; (B) fluorescence microscopy of wild-type or detA− slugs transformed with the prespore reporter [cotB]:GFP 17 h after the onset of starvation. Scale bar, 100 μm.
