Figure 2.

Venn diagram showing the numbers of predicted sequence clusters that receive high support (P > 0.5 and/or Z score < -2.0) and their distribution along the different genome combinations. The maximum number of 46 elements is shared between Synechocystis and Microcystis and only six are present in all genomes. One of these is Yfr1, other examples are CIRCE (Fig. 3) and the Yfr2 ncRNA family (Fig. 5). The figure was produced using Venny [32].
