One could certainly highlight a conceptual resemblance between social interactions as the
basis of societies and civilizations and the ability of molecules to interact in a noncovalent …

The lectin recognition hypothesis proposes that plant lectins mediate specificity in the
Rhizobium-legume symbiosis. Although the hypothesis was developed eight years before …

THE induction of nitrogen-fixing nodules in legume roots by soil bacteria from the genera
Rhizobium and Bradyrhizobium is host-plant-specific. This specificity is expressed at an …

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

Spontaneous mutants of Rhizobium meliloti L5-30 defective in motility or chemotaxis were
isolated and compared against the parent with respect to symbiotic competence. Each of the …

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 …

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 …

Infection of soybean root hairs by Bradyrhizobium japonicum is the first of several complex
events leading to nodulation. In the current proteomic study, soybean root hairs after …

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 …
