FIG. 3.—

Amino acid alignments for (A) AvrP123 and (B) AvrP4, with sites (clade A alleles only) under significant (P < 0.05) positive selection (M8) (shaded in dark gray). Alleles recovered from Linum marginale isolates are in black font and prefixed with Lm. Alleles recovered from L. usitatissimum isolates are in blue font and prefixed with Lu. Only those amino acids that differ from the top sequence are shown, with identical residues indicated by dots. Conserved Cysteine amino acid residues are highlighted in light gray. The names of the allelic variants used in transient transformation assays are underlined below.
