Network conservation. (A-C) Gene co-expression (link) conservation and (D-F) network neighbourhood conservation. One coordinate (x, y) corresponds to two fractions of link/neighbourhood conservation (or divergence); x is the fraction of conserved links/neighbourhoods when comparing the species on the x-axis to the species on the y-axis, and y is the fraction of conserved links/neighbourhoods when comparing the species on the y-axis to the species on the x-axis. The numbers in the plot is the CLR-threshold used to construct the compared networks (two CLR thresholds are given when different thresholds were used for the two compared networks). Results are given both for co-expression networks (Genes, green) and gene regulation networks (Transcription factors, blue).
