Figure 5
Sequence identity distribution of chromosomal predicted orthologs. Panels: (a), syntenic and non-syntenic products from the S. meliloti-A. tumefaciens (both chromosomes) comparison. Y-axis, relative proportions. (b), syntenic and non-syntenic products from the E. coli-S. typhimurium comparison. Y-axis, number of proteins in each range. (c), syntenic and non-syntenic products from the S. meliloti-E. coli comparison. Y-axis, relative proportions. Red bars, syntenic products. Blue bars, non-syntenic products.
