Multiple-sequence alignment of the Vip1 proteins. Sequence identity is indicated by shading, where violet is 100% sequence identity, pale blue is 80 to 100%, yellow is 60 to 80%, and white is <60%. Intervals of 10 amino acids are marked with “*.” SP, signal peptide. Proteins used in this analysis are as follows: Vip1Aa1 (Seq. ID no. 5 in reference 28), Vip1Ab1 (Seq. ID no. 21 in reference 28), Vip1Ac1 (GenBank accession number HM439098), Vip1Ad1 (accession number JQ855505), Vip1Ba1 (accession number AAR40886), Vip1Bb1 (accession number AAR40282), Vip1Ca1 (accession number AAO86514), and Vip1Da1 (accession number CAI40767).
