Constructs for insertional mutagenesis, transcriptional signal localization and gene regulation studies in root nodule and other bacteria.
TLDR
The new constructs provide useful tools for insertional mutagenesis, transcriptional signal localization and gene regulation studies in the root nodule bacteria and possibly other gram-negative bacteria. Expand
Maintenance of Intracellular pH and Acid Tolerance in Rhizobium meliloti.
TLDR
The ability to generate a large pH gradient under acid conditions may be a better indicator of acid tolerance in R. meliloti under field conditions than is growth on acidic agar plates. Expand
ActP controls copper homeostasis in Rhizobium leguminosarum bv. viciae and Sinorhizobium meliloti preventing low pH‐induced copper toxicity
TLDR
It is shown that copper homeostasis is an essential mechanism for the acid tolerance of these root nodule bacteria since it prevents this heavy metal from becoming overtly toxic in acidic conditions. Expand

Exoprotein Synthesis on Membrane-Bound Ribosomes and mRNA Transport-A Speculative Mechanism: A Background Perspective and Specificity oj Exop protein Synthesis. Expand
The transcriptional regulator gene phrR in Sinorhizobium meliloti WSM419 is regulated by low pH and other stresses.
TLDR
The phrR gene in Sinorhizobium meliloti WSM419, directly downstream from actA, is induced by low pH or certain stresses, but not in stationary phase or by other stresses (e.g. phosphate limitation, elevated temperature, high concentrations of sucrose or iron). Expand
Acid tolerance in Rhizobium meliloti strain WSM419 involves a two-component sensor-regulator system.
TLDR
Data implicate a two-component sensor-regulator protein pair in acid tolerance in R. meliloti and suggest their involvement in pH sensing and/or response by these bacteria. Expand
Properties of organic acid utilization mutants of Rhizobium leguminosarum strain 300
TLDR
The data support previous findings which suggest that utilization of exogenous dicarboxylates is essential for effective nodule development by R. leguminosarum. Expand
Problems of adverse pH and bacterial strategies to combat it.
This chapter aims to survey the problems faced by bacteria found in environments of adverse pH, to review strategies used to combat those problems and to ask how those strategies are implemented. AtExpand
Identification and characterization of fast- and slow-growing root nodule bacteria from South-Western Australian soils able to nodulate Acacia saligna
Abstract A total of 133 root nodule bacterial strains were isolated from nodules of Acacia saligna growing in soils from nine geographically separate locations in South-Western Australia; 40 wereExpand
