CYCLOPS, a mediator of symbiotic intracellular accommodation.
The initiation of intracellular infection of legume roots by symbiotic rhizobia bacteria and arbuscular mycorrhiza (AM) fungi is preceded by the induction of calcium signatures in and around the nucleus of root epidermal cells. Although a calcium and calmodulin-dependent kinase (CCaMK) is a key mediator of symbiotic root responses, the decoding of the calcium signal and the molecular events dow...
متن کاملDiscovery of a rhizobial RNA that is essential for symbiotic root nodule development.
All of the Azorhizobium, Bradyrhizobium, and Rhizobium genes known to be involved in the development of nitrogen-fixing legume root nodules are genes that code for proteins. Here we report the first exception to this rule: the sra gene; it was discovered during the genetic analysis of a Bradyrhizobium japonicum Tn5 mutant (strain 259) which had a severe deficiency in colonizing soybean nodules....
متن کاملThe 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...
متن کاملMtNF-YA1, A Central Transcriptional Regulator of Symbiotic Nodule Development, Is Also a Determinant of Medicago truncatula Susceptibility toward a Root Pathogen
Plant NF-Y transcription factors control a wide array of biological functions enabling appropriate reproductive and developmental processes as well as adaptation to various abiotic and biotic environments. In Medicago truncatula, MtNF-YA1 was previously identified as a key determinant for nodule development and establishment of rhizobial symbiosis. Here, we highlight a new role for this protein...
متن کاملNovel avidin-like protein from a root nodule symbiotic bacterium, Bradyrhizobium japonicum.
Bradyrhizobium japonicum is an important nitrogenfixing symbiotic bacterium, which can form root nodules on soybeans. These bacteria have a gene encoding a putative avidin- and streptavidin-like protein, which bears an amino acid sequence identity of only about 30% over the core regions with both of them. We produced this protein in Escherichia coli both as the full-length wild type and as a C-...
