Rhizobial bacteria enter a symbiotic association with leguminous plants, resulting in
differentiated bacteria enclosed in intracellular compartments called symbiosomes within …

Highlights•Nodulation of legumes is encoded by at least three genetic rhizobial
strategies.•The 'nod'strategy has been the most successful evolutionarily.•Evolution of nod …

Engineering N2-fixing symbioses between cereals and diazotrophic bacteria represents a
promising strategy to sustainably deliver biologically fixed nitrogen (N) in agriculture. We …

Horizontal transfer of genomic islands (GEIs), that is, chromosomal regions encoding
functions that can be advantageous for the host, plays a key role in bacterial evolution, but …

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

The growing human population requires increasing amounts of food, but modern agriculture
has limited possibilities for increasing yields. New crop varieties may be bred to have …

This important book provides a comprehensive review of our current knowledge of the
world's leguminous plants and their symbiotic bacteria. Written by Professor Janet Sprent, a …

Bacteria navigate their way often as individual cells through their chemical and biological
environment in aqueous medium or across solid surfaces. They swim when starved or in …

Biological nitrogen fixation is vital to nutrient cycling in the biosphere and is the major route
by which atmospheric dinitrogen (N 2) is reduced to ammonia. The largest single …

Plants form diverse symbioses with nitrogen-fixing bacteria to gain access to ammonium, a
product of the prokaryote-exclusive enzyme nitrogenase. Improving the symbiotic …
