Rhizobia are phylogenetically disparate α-and β-proteobacteria that have achieved the
environmentally essential function of fixing atmospheric nitrogen (N 2) in symbiosis with …

Rhizobia are one of the most important and best studied groups of bacterial symbionts. They
are defined by their ability to establish nitrogen-fixing intracellular infections within plant …

Over the last several decades, there have been a large number of studies done on the
genetics, biochemistry, physiology, ecology, and agronomics of the bacteria forming …

Since the world's population is still growing, food production should be increased. This
should be done without damaging the environment further and with a decreased input of …

Horizontal gene transfer has been recognized as one of the principal contributors to
bacterial evolution and diversification. One of the mechanisms involved in this process is …

Plasmids, extrachromosomal DNA molecules commonly found in bacterial and archaeal
cells, play an important role in bacterial genetics and evolution. Our understanding of …

In bacteria, niche adaptation may be determined by mobile extrachromosomal elements. A
remarkable characteristic of Rhizobium and Ensifer (Sinorhizobium) but also of …

Agrobacteria are important plant pathogens responsible for crown/cane gall and hairy root
diseases. Crown/cane gall disease is associated with strains carrying tumor-inducing (Ti) …

An analysis of the conjugative transfer of pRetCFN42d, the symbiotic plasmid (pSym) of
Rhizobium etli, has revealed a novel gene, rctA, as an essential element of a regulatory …

Conjugative transfer is one of the mechanisms allowing diversification and evolution of
bacteria. Rhizobium etli CFN42 is a bacterial strain whose habitat is the rhizosphere and is …
