Figure 4.

Average number of cells attached to (A), and cell aggregates (defined as a tight cluster of >10 cells) (B) on U. australis for GFP-labeled WT (solid fill) and GFP-labeled ΔptlL32 (horizontal stripes) after 6 h incubation. The number of green fluorescing cells or aggregates in each field of view was counted using ImageJ and an average expressed for cells per mm². Error bars represent standard deviation. Error bars represent standard deviation at 45 replicates and ^* denotes a significant difference with a p < 0.001 using the unpaired Students two-tailed t-test.
