Biological nitrogen fixation by Rhizobium-legume symbioses represents an environmentally
friendly and inexpensive alternative to the use of chemical nitrogen fertilizers in legume …

Colonization of host cells by rhizobium bacteria involves the progressive remodelling of the
plant–microbial interface. Following induction of nodulation genes by legume-derived …

Research on legume nodule development has contributed greatly to our current
understanding of plant–microbe interactions. However, the factors that orchestrate root …

Plants in their natural habitats are surrounded by a large number of microorganisms. Some
microbes directly interact with plants in a mutually beneficial manner whereas others …

Bacteria have evolved a wide variety of metabolic strategies to cope with varied
environments. Some are specialists and only able to survive in restricted environments; …

Molecules exuded by plant roots are thought to act as signals to influence the ability of
microbial strains to colonize the roots and to survive in the rhizosphere. Differential bacterial …

The soil-dwelling α-proteobacterium Sinorhizobium meliloti engages in a symbiosis with
legumes: S. meliloti elicits the formation of plant root nodules where it converts dinitrogen to …

Alfalfa (Medicago sativa) plants were exposed to drought to examine the involvement of
carbon metabolism and oxidative stress in the decline of nitrogenase (N2ase) activity …

Symbiotic nitrogen fixation (SNF) by intracellular rhizobia within legume root nodules
requires the exchange of nutrients between host plant cells and their resident bacteria. Little …

The complete reduction of molecular oxygen to water requires four electrons and is
catalyzed by cytochrome oxidase in aerobic bacteria and mitochondria. However, 1% to 3 …
