Figure 6From: Genome sequencing of two Neorhizobium galegae strains reveals a noeT gene responsible for the unusual acetylation of the nodulation factorsIllustration of d N / d S of the symbiosis genes of the two N. galegae strains. The HAMBI 540T symbiosis gene region used as model sequence. The blue bars represent the rate of synonymous substitutions d S , and the magenta-coloured bars the rate of nonsynonymous substitutions d N . The numbers on top of the bars are the d N /d S ratios.Back to article page
