The Orientation of Certain Root-nodule Bacteria at Interfaces, Including Legume Root-hair Surfaces

Root Colonization of Root and Nodule Endophytic Bacteria in Legume and Non Legume Plants Grown in Liquid Medium

Endophytes have a symbiotic relationship with the different parts of plants and could play a very important role in supporting the plant growth. In present study, 11 most efficient isolates were selected out of more than 200 endophytic bacteria isolated previously from roots of chickpea (Cicer arietinum), field pea (Pisum sativum), Lucerne (Medicago sativa), wheat (Triticum aestivum) and oat (A...

The Legume Root Nodule: From Symbiotic Nitrogen Fixation to Senescence

Biological nitrogen fixation (BNF) is the biological process by which the atmospheric nitrogen (N2) is converted to ammonia by an enzyme called nitrogenase. It is the major source of the biosphere nitrogen and as such has an important ecological and agronomical role, accounting for 65 % of the nitrogen used in agriculture worldwide. The most important source of fixed nitrogen is the symbiotic a...

[Root nodule bacteria on leguminous plants].

Regulators and regulation of legume root nodule development.

Nitrogen is the nutrient plants require in the highest amount, and in agriculture nitrogen availability has a major influence on both yield and product quality. In nature plants acquire nitrogen by assimilation of nitrate and ammonium or from dinitrogen through association with nitrogen-fixing bacteria. Symbiotic nitrogen fixation, where the plant supplies the carbon source for the energy-depen...

Molecular Diversity of Legume Root-Nodule Bacteria in Kakadu National Park, Northern Territory, Australia

BACKGROUND Symbiotic relationships between leguminous plants (family Fabaceae) and nodule-forming bacteria in Australia native ecosystems remain poorly characterized despite their importance. Most studies have focused on temperate parts of the country, where the use of molecular approaches have already revealed the presence of Bradyrhizobium, Ensifer (formerly Sinorhizobium), Mesorhizobium and ...
