From: Allelic diversity and phylogeny of homB, a novel co-virulence marker of Helicobacter pylori
Similarity plot representation of homB (black lines) and homA (grey lines) genes of various Helicobacter pylori strains. The plot was generated by using 16 strains representative of each gene, with the Jukes-Cantor correction (1-parameter), a 200-bp window, a 20-bp step, without Gap Strip and the jhp870 gene sequence as reference (GenBank accession number NC_000921). The arrow delineates the region which discriminates between homB and homA genotypes. bp, base pair.
