Re-considering the signed break-points (marked in blue) between the two gene orders exemplified in Fig. 2, this time taking into account the PQ-tree representing the corresponding gene cluster. A The PQ-tree. Note that in this figures, as well as the following figures, P-nodes are marked with circles and Q-nodes are marked with rectangles. B The first gene order. C The second gene order
