Figure 4From: Reconstruction of an ancestral Yersinia pestisgenome and comparison with an ancient sequenceAncestral adjacency graph obtained using DeCo on the set of 3656 gene families. Each node is colored according to its number of neighbors: green for two (ideal, linear case), turquoise for one (where one adjacency has been lost), orange for three and gray for four (when an error in the number of ancestral copies creates conflict in the ancestral gene order).Back to article page
