Data on top line includes polymorphic count from both species; data on bottom line include polymorphic count from A. thaliana only. Degree of significance remained the same regardless of sample set and/or inclusion of polymorphic data from one or both species. N, nonsynonymous; S, synonymous; NA, not applicable; NS, not significant.
