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 …

This volume surveys the chemistry, biochemistry, biosynthesis, metabolism and
pharmacological properties of lectins. Lectins, which are most commonly found in plants, are …

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 …

Biotic interactions in the rhizosphere are biologically important, and although many of those
interactions have been well studied, the role of secreted proteins in the cross-talk between …

In the soybean (Glycine max [L.] Merr.) N2-fixing symbiosis, suboptimal root zone
temperatures (RZTs) slow nodule development, especially at temperatures below 17 [deg] …

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 …

The nodulation genes of rhizobia are regulated by the nodD gene product in response to
host-produced flavonoids and appear to encode enzymes involved in the production of a …

Mutant strains of Rhizobium leguminosarum have been isolated in which the transposon Tn
5 was inserted into the cloned nodulation genes. The mutant strains were examined for their …

The ectomycorrhizal fungus Paxillus involutus Fr. was grown in the presence of root exudate
of Pinus resinosa Ait, for two weeks. The effect of root exudate on the synthesis of ethanol …
