Figure 3From: Population-associated differences between the phase variable LPS biosynthetic genes of Helicobacter pyloriNeighbour-joining tree based on combined sequencing data of the two alpha-1,3-fucosyltransferase genes (HP0651 and HP0379). All distances are based on Kimura two-parameter estimates and are to scale (scale bar, lower left). Population are coded as in Figure 1; Solid shapes indicate phase variable alleles and empty shapes indicate non-phase variable alleles.Back to article page
