aTo eliminate potential artifacts caused by misalignment, all positions containing a deletion or insertion in the alignment within 5 adjacent position both upstream and downstream were discarded from calculation [16]; the results changed minimally when a stricter criterion was applied by eliminating 10 adjacent positions (data not shown).
