  1. Class 1: Phy and Pop>95%; Class 2: Phy>95% and 50%<Pop<95%; Class 3: 50%<Phy<95% and Pop>95%; Class 4: sites with alignment gaps and Pop>95%; Class 5: Phy>95% and Pop<50%; Class 6: Phy<50% and Pop>95%; Class 7: 50%<Phy<95% and 50%<Pop<95%; where Phy and Pop stands for the posterior probability of the amino-acid site being positively selected using Yang (1997) phylogenetic approach and Wilson and McVean (2006) population genetics method, respectively.
  2. Amino-acid sites identified using 37 Prunus SFB sequences (Nunes et al., 2006) are marked as:
  3. *amino acids identified by Phy and Pop;
  4. #amino-acid sites identified using only Phy;
  5. &amino-acid sites identified using only Pop and
  6. +sites with alignment gaps detected as being positively selected by Pop.
