	% variability Axis 1 11.7 Axis 2 6.7 Axis 3 4.6 Axis 4 4.4 Axis 5 4.0 Axis 6 3.9
Red (), blue () and green squares () correspond to genes proposed as being acquired by HGT and included in regions with a low, high and non-deviated G+C content, respectively. Yellow cross diagonals (x) correspond to putative highly expressed genes.
