FIG. 2.

Mixed autoaggregation of strains expressing α1 bundlin and β6 bundlin alleles. Strain E2348/69 expressing α1 bundlin and DsRed and strain RN587/1 expressing β6 bundlin and eGFP were incubated together and examined by immunofluorescence microscopy to detect red (left panel) or green (middle panel) fluorescent bacteria in microcolonies. The right panel shows the merged red and green images. Bar = 20 μm.
