Abstract Information is reviewed under various headings, including (1) genetic requirement
for nodulation;(2) isolation and identification of Rhizobium nod genes;(3) the common …

Attachment of bacteria to plant cells is one of the earliest steps in many plant‐bacterium
interactions. This review covers the current knowledge on one of the best‐studied examples …

194 HALVERSON AND STACEY for many plant-microbe interactions. The purpose of this
article is to identify the signal molecules involved in plantmicrobe interactions and the …

The Rhizobium leguminosarum biovar viciae genome contains several genes predicted to
determine surface polysaccharides. Mutants predicted to affect the initial steps of …

Rhizobium and Bradyrhizobium have attracted great attention due to their capacity to
establish a symbiosis with the roots of legumes, resulting in the reduction of atmospheric …

A genome-wide transcriptional profile of Bradyrhizobium japonicum, the nitrogen-fixing
endosymbiont of the soybean plant, revealed differential expression of approximately 15 …

Nitrate is usually the principle form of mineral nitrogen available to plants in the soil. Many
legume species also have direct access to biologically fixed nitrogen, but preferentially …

Plant lectins have been implicated as playing an important role in mediating recognition and
specificity in the Rhizobium–legume nitrogen-fixing symbiosis. To test this hypothesis, we …

Transgenic alfalfa (Medicago sativa L. cv Regen) roots carrying genes encoding soybean
lectin or pea (Pisum sativum) seed lectin (PSL) were inoculated with Bradyrhizobium …

During the Rhizobium-legume interactions that lead to the establishment of the nitrogen
fixing symbiosis, an exchange of molecular signals regulates the expression of genes …
