Legume-nodulating betaproteobacteria: diversity, host range, and future prospects.
Rhizobia form specialized nodules on the roots of legumes (family Fabaceae) and fix nitrogen in exchange for carbon from the host plant. Although the majority of legumes form symbioses with membersExpand

Role of soil microorganisms in improving P nutrition of plants
Phosphorus (P) is one of the major plant growth-limiting nutrients although it is abundant in soils in both inorganic and organic forms. Phosphate solubilizing micro-organisms (PSMs) are ubiquitousExpand

Herbaspirillum colonization increases growth and nitrogen accumulation in aluminium-tolerant rice varieties
Summary • Varieties of rice (Oryza sativa) differing in tolerance to aluminium (Al) were evaluated for their N-fixation ability after inoculation with a gusA-marked strain of HerbaspirillumExpand

Identification of a New Member of the Phage Shock Protein Response in Escherichia coli, the Phage Shock Protein G (PspG)*[boxs]
The phage shock protein operon (pspABCDE) of Escherichia coli is strongly up-regulated in response to overexpression of the filamentous phage secretin protein IV (pIV) and by many other stressExpand

A previously undescribed pathway for pyrimidine catabolism.
The b1012 operon of Escherichia coli K-12, which is composed of seven unidentified ORFs, is one of the most highly expressed operons under control of nitrogen regulatory protein C. Examination ofExpand

Sulfur and nitrogen limitation in Escherichia coli K-12: specific homeostatic responses.
We determined global transcriptional responses of Escherichia coli K-12 to sulfur (S)- or nitrogen (N)-limited growth in adapted batch cultures and cultures subjected to nutrient shifts. Using twoExpand

SlyA Regulates Type III Secretion System (T3SS) Genes in Parallel with the T3SS Master Regulator HrpL in Dickeya dadantii 3937
ABSTRACT The hypersensitive response and pathogenicity (hrp) genes of Dickeya dadantii 3937 encode a type III secretion system (T3SS) which is essential for its full virulence. Previous studies ofExpand

Lessons from Escherichia coli genes similarly regulated in response to nitrogen and sulfur limitation.
We previously characterized nutrient-specific transcriptional changes in Escherichia coli upon limitation of nitrogen (N) or sulfur (S). These global homeostatic responses presumably minimize theExpand

Characterization of an Acid-Inducible Sulfatase in Salmonella enterica Serovar Typhimurium
ABSTRACT Sulfatases of enteric bacteria can provide access to heavily sulfated mucosal glycans. In this study, we show that aslA (STM0084) of Salmonella enterica serovar Typhimurium LT2 encodes aExpand
