Fig. 3From: Multilevel comparative bioinformatics to investigate evolutionary relationships and specificities in gene annotations: an example for tomato and grapevineOrtholog/paralog networks detected with a stringent e-value threshold (e− 50). a Bar chart showing the number of networks classified according to their size. b Scatter plots showing the distribution of the networks based on the respective number of genes from S. lycopersicum and V. vinifera. The diameter of the circles is proportional to the number of BBHs inside each networkBack to article page
