Rhizobium, Bradyrhizobium, and Azorhizobium species are able to elicit the formation of
unique structures, called nodules, on the roots or stems of the leguminous host. In these …

How good and how pleasant it is for organisms to dwell together in unity! And, probably, how
common it is in the biological world. This review concerns a dramatic association, one of the …

Initial stages in the Rhizobium–legume symbiosis can be thought of as a reciprocal
molecular conversation: transmission of a gene inducer from legume host to bacterium, with …

A region of 16.8 kb of the Sym (biosis) plasmid pRL1JI of Rhizobium leguminosarum,
consisting of the established 9.7 kb nodulation region which confers nodulation ability on …

The subject is reviewed under the headings: legume nodulation; role of the bacterial
symbiont; nodulation as a developmentally regulated phenomenon; plant nodulation …

The early events in legume nodulation by Rhizobium spp. involve a conserved gene cluster
known as the common nod region. A broad-host-range plasmid (pEA2-21) containing a …

At least nine different bacterial proteins belong to the LysR family. The gene sequence for
one of these proteins is presented here. Six others (Escherichia coli LysR, IlvY, CysB; …

Symbiotic nitrogen fixing bacteria—known as rhizobia—harbour a set of nodulation (nod)
genes that control the synthesis of modified lipo-chitooligosaccharides, called Nod factors …

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

Rhizobium trifolii mutants containing Escherichia coli lac gene fusions to specific nodulation
(nod) genes were used to characterise phenolic compounds secreted from the roots of white …
