HpaR1 is involved in the tolerance of Xcc to phenol, SDS, D-sorbitol and heavy metal cations.
Cultures of Xcc strains were diluted and plated on an NYG plate supplemented with different concentrations of phenol (A) SDS (B) D-sorbitol (C) and heavy metal salts (CoCl2, CdCl2 and ZnSO4) (D). Bacterial colonies were counted after incubation at 28 °C for 3 days. The representative results of only one out of three replicated experiments are presented.
