Root-knot nematodes are predicted to encode PSY-like peptides. (A) Amino acid sequences of the conserved PSY motif from Arabidopsis [Arabidopsis thaliana] AtPSY1 and from the bacterial species, Xoo (RaxX13-c), compared with the predicted translation products from the three MigPSY types. Letters in blue represent the conserved amino acids of the PSY motif. For each of the MigPSY types, the predicted product extending from the conserved motif to the C terminus is shown. (B) Protein logo alignment of 11 predicted MigPSY gene products in the species M. incognita, M. javanica, and M. arenaria (SI Appendix, Table S1). Spaces with no amino acids indicate positions that are not present in the majority of the predicted products. The amino acid sequences are predicted to contain a highly conserved N-terminal secretion signal peptide followed by a PSY-like domain beginning 1 to 4 amino acids after the signal peptide cleavage site.
