Target genomic locus and integrative expression vectors. (a) Schematic of B. theta genomic locus PUL75 containing genes required for homogalacturonan (HG) utilization (top). These genes are deleted in the B. theta ΔPUL75 strain (bottom). (b) Growth profiles of wild-type (WT) B. theta (grey) and the ΔPUL75 strain (purple) in MM containing either glucose (GLC) or HG as sole carbon source. Growth was measured by OD600 readings over the course of 16 h. Values represent the average of three biological replicates. Variation is represented by standard error of the mean (s.e.m.) (c) Plasmid maps of the pINT (left) and pNBU2 (right) vectors. The orientation of the DX, AG, and ON, expression cassettes and the sequence of the MCS are indicated.
