The symbiotic interaction of rhizobia with Legume roots results in nodule formation and
eventually nitrogen fixation. An alternative to nitrogenous fertilizers is the application of …

Legume diversity is very large in the tropics, and legume evolution appears to have followed
a tropical to temperate direction. Many tropical legumes have been domesticated as crops …

Rhizobial bacteria are commonly found in soil but also establish symbiotic relationships with
legumes, inhabiting the root nodules, where they fix nitrogen. Endophytic rhizobia have also …

Brazil is the largest producer and consumer of common bean worldwide, and the crop can
benefit from its symbiosis with a variety of rhizobia by means of biological nitrogen fixation in …

Common bean is one of the primary protein sources in third-world countries. They form
nodules with nitrogen-fixing rhizobia, which have to be adapted to the local soils …

The current interest on biodiversity, allied with the use of powerful molecular biology
techniques, are revealing the nodulation abilities of tropical legumes, their preferences in …

The ability of indigenous rhizobia to nodulate a legume crop effectively, or to act as barrier to
the successful establishment of inoculant strains, is critical to successful establishment and …

The application of lime to acidic soils may provide nutrients and favourable conditions to kick-
start the growth of bacterial cells in the short term, while long term alteration due to liming …

Rhizobia are soil bacteria that fix atmospheric nitrogen in symbiosis with legumes in
specialized organs called nodules. The legumes thus acquire the autonomy to grow in …

A single gram of soil is said to contain more than 8 billion bacterial cells, representing up to
50,000 different species1. These microorganisms play important roles, from tweaking how …
