Table 1. Summary of dN/dS analysis for the SR superfamily.
| SR family | No. of sequences analyzed (total tree length) | Significance |
|---|---|---|
| sra | 8 (4), 4 (9), 10 (32) | — |
| srb | 4 (7), 7 (8), 4 (10), 6 (13), 12 (20) | — |
| srd | 4 (5), 6 (6), 7 (8), 6 (10), 7 (18), 7 (19), 5 (28) | 1/7 |
| sre | 7 (13), 7 (13), 27 (143) | — |
| srg | 4 (6), 7 (7), 5 (8), 24 (61) | — |
| srh | 5 (6), 6 (6), 6 (8), 7 (8), 8 (8), 8 (15), 19 (28), 16 (31) | — |
| sri | 5 (5), 5 (8), 7 (12), 13 (18), 16 (29) | — |
| str | 6 (5), 6 (8), 5 (10), 12 (13), 40 (23), 22 (78), 27 (78) | — |
| sru | 4 (6), 7 (9), 6 (11), 8 (28) | — |
| srv | 4 (6), 5 (8), 7 (9), 12 (38) | — |
| srw | 4 (3), 5 (3), 12 (21), 9 (22), 14 (26) | 1/5 |
| srx | 8 (16), 7 (18), 8 (18), 20 (77), 6 (184) | — |
| srz | Many (see Table 2) | P < 0.0001 |
All results were statistically insignificant (marked “—”), with the exception of the srz family (see Table 2) and one group each from the srd and srw families. The significance for the srw case was marginal (P ≈ 0.01) and may result from a multiple testing artifact. The significance for the srd case was high (P < 0.0001) but was found in only one small clade of the family.
