Acid tolerance in Rhizobium meliloti strain WSM419 involves a two-component sensor-regulator system.

Microbiology (Reading, England) - 1 Jul 1996

Tiwari R P, Reeve W G, Dilworth M J, Glenn A R

Abstract excerpt

An acid-sensitive mutant, TG5-46, derived from Rhizobium meliloti WSM419 by Tn5 mutagenesis, fails to grow below pH 6.0 whereas the parent strain grows at pH 5.7. The DNA sequence of a 2.2 kb rhizobial DNA region flanking Tn5 in TG5-46 contains two open reading frames, ORF1 (designated actS) and ORF2 (designated actR), having high similarity to the sensor-regulator pairs of the two-component systems involved in...
