Genes and signals in the rhizobium-legume symbiosis.
Rhizobium-legume symbiosis begins with two free living organisms, and ends with an intimate cellular co-existence. Rhizobium bacteria recognize specific plants, provoke development of a root nodule, and invade the plant tissue. Eventually, the Rhizobium cell transfers itself into a host cell, surrounds itself with plant membrane, and arranges a nutrient exchange in which the bacteria brings fix...
متن کاملIron: an essential micronutrient for the legume-rhizobium symbiosis
Legumes, which develop a symbiosis with nitrogen-fixing bacteria, have an increased demand for iron. Iron is required for the synthesis of iron-containing proteins in the host, including the highly abundant leghemoglobin, and in bacteroids for nitrogenase and cytochromes of the electron transport chain. Deficiencies in iron can affect initiation and development of the nodule. Within root cells,...

متن کاملIntergeneric transfer of genes involved in the Rhizobium-legume symbiosis.
Genes that seem to be involved in the initial steps of infection of a legume by Rhizobium have been transferred, by transformation, to mutant strains of Azotobacter vinelandii that are unable to fix nitrogen. These genes code for a surface antigen that binds specifically to a protein from the host plant.
