The early molecular dialogue between soybean and the bacterium Bradyrhizobium japonicum is crucial for triggering their symbiotic interaction. Here we found a single large genomic locus that is widely separated from the symbiosis island and was conspicuously induced within minutes after the addition of genistein. This locus (named BjG30) contains genes for the multidrug efflux pump, TetR family...

In Rhizobium strains the transcription of symbiosis plasmid-localized nod genes, except nodD, is induced by plant flavonoids and requires the nodD gene product. In order to localize NodD protein in R. leguminosarum, a NodD protein-specific antiserum was raised against a lacZ'-'nodD gene fusion product. Using these antibodies, we determined that the NodD protein is located exclusively in the cyt...

Nonobese diabetic (NOD) is an inbred mouse strain susceptible to development of T cell-mediated autoimmune diabetes. The strain is characterized by high percentages of T lymphocytes in lymphoid organs. The syngeneic mixed lymphocyte reaction (SMLR), a T cell response to self MHC class II Ag, is reportedly involved in the generation of a number of immunoregulatory cells, including suppressor ind...

Bradyrhizobium sp. DOA9 isolated from the legume Aeschynomene americana exhibited a broad host range and divergent nodulation (nod) genes compared with other members of the Bradyrhizobiaceae. Genome analysis of DOA9 revealed that its genome comprised a single chromosome of 7.1 Mbp and a plasmid of 0.7 Mbp. The chromosome showed highest similarity with that of the nod gene-harboring soybean symb...

For Bradyrhizobium japonicum, the chemotactic and the nod gene-inducing effects of hydroxycinnamic acids and two of their derivatives were compared with those of isoflavonoids. Only the hydroxycinnamic acids were strong chemoattractants, while the other substances tested were chemotactically inactive. Besides the known nod gene induction by isoflavonoids, a weak nod gene induction by coniferyl ...

The rhizobial-derived signaling molecule Nod factor is essential for the establishment of the Medicago truncatula/Sinorhizobium meliloti symbiosis. Nod factor perception and signal transduction in the plant involve calcium spiking and lead to the induction of nodulation gene expression. It has previously been shown that the heterotrimeric G-protein agonist mastoparan can activate nodulation gen...

Conditioning regimens prior to hematopoietic stem cell transplantation (HSCT) are often accompanied by a period of aplasia characterized severe neutropenia, anemia, and thrombocytopenia. Long-term antibacterial immunosuppressive therapy in patients with graft-versus-host disease (GVHD) exacerbates depression. Colony-stimulating factors, erythropoietins, thrombopoietin receptor agonists used cor...

background anaerobic-inducible promoters are alternatives of chemical-inducible promoters for expression of recombinant proteins especially in conditions where chemical induction is not possible or anaerobic conditions are preferable. the nirb promoter is the promoter of the first gene of nir operon in escherichia coli, which encodes nadh-dependent nitrite reductase. this promoter is naturally ...

Rhizobium-made Nod factors induce rapid changes in both Ca(2+) and gene expression. Mutations and inhibitors that abolish Nod-factor-induced Ca(2+) spiking block gene induction, indicating a specific role for Ca(2+) spiking in signal transduction. We used transgenic Medicago truncatula expressing a "cameleon" Ca(2+) sensor to assess the relationship between Nod-factor-induced Ca(2+) spiking and...

Cultivar Afghanistan peas are resistant to nodulation by many strains of Rhizobium leguminosarum bv. viciae but are nodulated by strain TOM, which carries the host specificity gene nodX. Some strains that lack nodX can inhibit nodulation of cv. Afghanistan by strain TOM. We present evidence that this "competitive nodulation-blocking" (Cnb) phenotype may result from high levels of Nod factors in...
