  1. BLASTX and PFAM hits were considered significant when E-value ≤ 1e-4 and 1e-5, respectively.
  2. aNS: non-secreted; S: secreted.
  3. bHighest calculated dN/dS ratio among all pairwise comparisons within each HGG.
  4. cLength is 271 (M. medusae f. sp. deltoidae, M. medusae f. sp. tremuloidae and M. occidentalis), and 276 (M. larici-populina); an 86 amino acids insertion and a 5 amino acids minisatellite are also present in a M. medusae f. sp. deltoidae unisequence (length: 357) and a M. larici-populina unisequence (length: 281), respectively.
  5. dA 44 amino acids deletion (including 4 Cys residues) is present in a M. medusae f. sp. deltoidae unisequence.
  6. eLength is 119 (M. medusae f. sp. tremuloidae) and 123 (M. occidentalis).
  7. fA 12 amino acids minisatellite is present in a M. occidentalis unisequence (length: 181).
  8. gAdditional Cys residues are present before the signal peptide cleavage site.
