Evolutionary rates and purifying selection of the <i>MAGO</i> and <i>Y14</i> families.

<p>(<b>a</b>) Evolutionary rates of the MAGO and Y14 families inferred from all included homologous sequences. <i>dN</i>: non-synonymous substitution rate; <i>dS</i>: synonymous substitution rate. ω = <i>dN</i>/<i>dS</i>. (<b>b</b>) Comparison of the evolutionary rate. <i>dN</i> and <i>dS</i> values were determined with different inputs. 1, <i>Y14</i> genes excluding <i>Y14b</i> copies; 2, <i>Y14</i> genes excluding <i>Y14a</i> copies; 3, <i>MAGO</i> genes excluding <i>MAGO2</i> copies. 4, <i>MAGO</i> genes excluding <i>MAGO1</i> copies; 5, all <i>Y14</i> genes and 6, all <i>MAGO</i> genes.
