Summary Nodulation in alfalfa ( Medicago sativa L.) is controlled by a systemic feedback regulatory mechanism that suppresses nodule initiation in younger portions of the root system. Excision of primary root nodules induced by wild-type Rhizobium meliloti stimulates the formation of new nodules on lateral roots.

2009 Third International Symposium on Plant Growth Modeling, Simulation, Visualization and Applications, 2009
In legume plants, the balance of nodule formation is maintained by a long-distance shoot-root signalling system known as autoregulation of nodulation. Due to the complexity of plants’ signalling nature, the underlying mechanisms of autoregulation of nodulation still remain largely unknown.

Journal of Integrative Plant Biology
ABSTRACTThe combination of mutation‐based genetics and functional genomics has allowed a detailed dissection of the nodulation‐induction and autoregulation of nodulation (AON) pathways of soybean. Applicable to all legumes, nodulation is induced by Rhizobium/Bradyrhizobium‐produced lipopolysaccharides (Nod factors), perceived by Nod factor receptors ...

Autoregulation of soybean–Bradyrhizobium nodule symbiosis is controlled by shoot or/and root factors
World Journal of Microbiology and Biotechnology, 1999Two strains of Bradyrhizobium japonicum were evaluated with five commercial cultivars of soybean (Clark, Crauford, Davis, Centaur, and Nessen) and one hypernodulating mutant NOD1-3. The hypernodulating NOD1-3 produced 30–50 times the number of nodules of commercial cultivars either inoculated with B. japonicum strain USDA 123 or RCR 3409.

Expression and promoter analysis of Glycine max nodule autoregulation receptor kinase gene
Legume-rhizobia symbioses contribute at least 20% of the biosphere's supply of reactive nitrogen. These unique associations rely on the exchange of specific molecular signals between nitrogen-fixing soil bacteria, collectively called rhizobia, and their host plants and, with few exceptions, result in the formation of root nodules, which provide an ...openaire +1 more source
A proteomic approach to study the autoregulation of nodulation in Medicago truncatula.
2011Plant belonging to Leguminosae family can establish a symbiotic relationship with nitrogen-fixing bacteria, termed rhizobia, that lead to the formation of a new organ, the root nodule. This organogenetic pathway starts as a consequence of a molecular cross-talk between plants and bacteria. The systemic pathway, also termed Autoregulation Of Nodulation (
