Symbiotic nitrogen fixation by rhizobia in legume root nodules injects approximately 40
million tonnes of nitrogen into agricultural systems each year. In exchange for reduced …

The literature on nitrogen (N) form effects on plants at different stages of their development
has been critically reviewed, assessing the possible mechanisms of these effects. In …

Nitrogen is generally considered one of the major limiting nutrients in plant growth. The
biological process responsible for reduction of molecular nitrogen into ammonia is referred …

Nitrogen is the most limiting nutrient in most agro-ecosystems and thus critical for sustaining
high yields. Conventional agricultural practices use synthetic fertilizers to ensure an …

Microbial ecology is the study of interactions among microbes in natural environments and
their roles in biogeochemical cycles, food web dynamics, and the evolution of life. Microbes …

Legumes are ecologically and economically important plants that contribute to nutrient
cycling and agricultural sustainability, features tied to their intimate symbiosis with nitrogen …

Leguminous plants possess the almost unique ability to enter symbiosis with soil-resident,
nitrogen fixing bacteria called rhizobia. During this symbiosis, the bacteria physically …

By analyzing successive lifestyle stages of a model Rhizobium–legume symbiosis using
mariner-based transposon insertion sequencing (INSeq), we have defined the genes …

In legume nodules, symbiosomes containing endosymbiotic rhizobial bacteria act as
temporary plant organelles that are responsible for nitrogen fixation, these bacteria develop …

Rhizobial bacteria colonize legume roots for the purpose of biological nitrogen fixation. A
complex series of events, coordinated by host and bacterial signal molecules, underlie the …
