Feature 2 means that an Ile, Leu, Val, or Pro is located at the third or fourth residue of the protein. Feature 3 means no Asp or Glu residues within the first 12 amino acids. The matrix is boolean, i.e., 1 means true and 0 means false. The involved rhizobial species are abbreviated as Sino for Sinorhizobium, Meso for Mesorhizobium, and Brady for Bradyrhizobium. The effectors marked by * are from the four strains considered in this study. The third column lists GI numbers from NCBI GenBank.
