Fig 5. thiG is involved in regulating xanthan biosynthesis genes expression but had no effect on xanthan production.

Fig 5

(A) The expression level of 13 gum genes in the thiG mutant compared to the wild type strain ZJ173.Wild-type strain ZJ173 expression level was set as 1. gyrB was used as an internal control for data analyses. (B) The xanthan production in the mutant compare with the wild-type strain ZJ173. Wild-type strain ZJ173 was set as equal to 100%. (C) Biofilm formation is decreased in gumE, gumM and gumH mutants compared to the wild-type strain ZJ173. Vertical bars represent standard errors. Different letters above the data bars represents the significant value P<0.05.
