Fig. 1

Distribution of the four pangene categories between upper and lower half of 11 Vibrionaceae genomes. Bars in the histogram show percent of total CDSs per chromosome for each pangene category. Core and softcore genes are overrepresented on the upper half of Chr 1, shell and cloud genes are overrepresented on the lower half. On Chr 2 the genes are more evenly distributed between the upper and lower halves of Chr 2
