Figure 4From: Comparative transcriptomic analyses revealed divergences of two agriculturally important aphid speciesDistribution of Ka and Ks between orthologs in grain aphid and pea aphid. Sequences with Ka/Ks > 2 fall above the dash line; while sequences with Ka/Ks of 1–2 fall between the solid and dash lines; Sequences with Ka/Ks <1 below the solid line. Analysis was performed using the method of Yang & Nielsen [21].Back to article page
