Distribution of synonymous substitution rates (Ks) for all cDNAs transferred between chemotrophic (red), between phototrophic (blue), and from chemotrophic-to-phototrophic (green) communities. The inset expands the lowest Ks (<0.01) bin, illustrating the low Ks peak (Ks ~0 to 0.2) in chemotrophic and especially phototrophic communities. The top axis uses recently published prokaryotic mutation rates to bracket likely upper (top) and lower (bottom) limits on cDNA transfer times.
