Phosphate limitation induces catalase expression in Sinorhizobium meliloti, Pseudomonas aeruginosa and Agrobacterium tumefaciens
Abstract
Growth of Sinorhizobium meliloti under Pi-limiting conditions induced expression of the major H2O2-inducible catalase (HPII) gene (katA) in this organism. This transcription required the PhoB transcriptional regulator and initiated from a promoter that was distinct from the OxyR-dependent promoter which activates katA transcription in response to addition of H2O2. In N2-fixing root nodules, katA was transcribed from the OxyR- and not the …
