FIG. 4.
culB− cells have a propensity to form stalk cells in culB−/wild-type chimeras. Cells marked with an actin/GFP reporter plasmid were mixed with unmarked wild-type cells in a 1:9 ratio and allowed to develop into fruiting bodies. The actin/GFP-marked wild-type cells (WT) used as a control were mixed with unmarked wild-type cells.
