Figure 5From: Deciphering the complex leaf transcriptome of the allotetraploid species Nicotiana tabacum: a phylogenomic perspectiveNucleotide substitution rates in Nicotiana genes. Frequency histograms showing the rate of synonymous nucleotide substitutions (Ks) in orthologous genes between N. tabacum and S. lycopersicum (A), N. sylvesteris and N. tomentosiformis (B), N. tabacum and N. sylvesteris (C) and N. tabacum and N. tomentosiformis (D).Back to article page
