Fig. 6From: The Xylella fastidosa RTX operons: evidence for the evolution of protein mosaics through novel genetic exchangesNucleotide sequence alignments of N-terminal repeats with homology to other Xf strains and other organisms. a The Xf (Temecula) RTX1 operon contains an N-terminal repeat homologous to the N-terminus of RTX1 from strain 9a5c. b The Xf (Dixon) RTX4 operon contains an N-terminal repeat homologous to the N-terminus of RTX4 from Ralstonia solanacearumBack to article page
