Figure 4. Iron recovery predominates behaviours of E. coli in colonic mucus.

Figure 4

Genes (a) belonging to Fur regulon29 or (b) repressed by RyhB30 or (c) responding to oxygen levels (ArcA/FNR)31 of E. coli as reported previously were listed out. The ratio of expression levels of the whole panel of genes in colonic mucus relative to colonic contents is shown. Several genes/clusters were highlighted in indicated colours referring to same genes shown in Supplementary Fig. 9. The annotations of all displayed dots were listed in Supplementary Data 4. The red dotted line indicates a ratio of unity between colonic mucus and contents.
