Title : Understanding the legume-rhizobia symbioses: key role of microscopy techniques Authors : Lucas, M. This symbiosis is significantly important for the nitrogen input in befween agricultural and natural ecosystems, but it can be affected by environmental stresses.

Nodulation is a complex process not completely understood; some features differ depending on the what is the symbiotic relationship between bacteria and leguminous plants, and they lead to distinct nodule types. After a specific recognition between the symbionts through the exchange of bacterial and plant signalling molecules, the nodule primordium is induced and rhizobia enter the root cortex and infect thf of this primordium.

Bacteria are released into the host cell surrounded by a plantderived membrane and form synbiotic new cellular compartment, the symbiosome, which is a nitrogen-fixing microfactory. Based on several characteristics of the symbiosome including its metabolic behaviour, the composite origin of the membrane, the cytoskeletal dynamics and symbiosome segregation during the division of rhizobia-infected cells in certain legume nodules, symbiosome can be considered an organelle-like 1.

Legume nodules are probably one of the most fascinating plant organs. They have been studied for more than a century, and microscopy techniques have been and will be key tools to enhance our understanding bewteen this symbiosis. Files in This Item:.

The symbiotic association between certain soil bacteria rhizobia and most legumes leads to the formation of root nodules, symbiotic organs in which the fixation of atmospheric nitrogen takes place.

Determinations of oxidase and catalase activity were performed by the methods of Kovaks and Graham-Parkerrespectively. The endosymbiotic association between legumes and soil bacteria called rhizobia leads to the formation of a new root-derived organ called the nodule in which differentiated bacteria convert atmospheric nitrogen into a form that can planta assimilated by the host plant.
