The new CDS arsR is involved in arsenate resistance in Xcc strain 8004. (A) Domain organization of arsR predicted by SMART ( webcite). (B) Genomic localization of ArsR and its flanking genes in the chromosome of Xcc strain 8004. (C) RT-PCR analysis of the arsR-XC_2295-XC_2294 operon. (D) Survival of Xcc strain 8004 and its derivatives in liquid NYG media with different concentrations of sodium arsenate. (E) Growth of Xcc strain 8004 and its derivatives on an NYG plate with 0.5 mM sodium arsenate. ΔarsR (arsR) indicates the complemented deletion mutant defective in arsR.
