    A putative Ca2+ and calmodulin-dependent protein kinase required for bacterial and fungal symbioses (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-14
    Description: Legumes can enter into symbiotic relationships with both nitrogen-fixing bacteria (rhizobia) and mycorrhizal fungi. Nodulation by rhizobia results from a signal transduction pathway induced in legume roots by rhizobial Nod factors. DMI3, a Medicago truncatula gene that acts immediately downstream of calcium spiking in this signaling pathway and is required for both nodulation and mycorrhizal infection, has high sequence similarity to genes encoding calcium and calmodulin-dependent protein kinases (CCaMKs). This indicates that calcium spiking is likely an essential component of the signaling cascade leading to nodule development and mycorrhizal infection, and sheds light on the biological role of plant CCaMKs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levy, Julien -- Bres, Cecile -- Geurts, Rene -- Chalhoub, Boulos -- Kulikova, Olga -- Duc, Gerard -- Journet, Etienne-Pascal -- Ane, Jean-Michel -- Lauber, Emmanuelle -- Bisseling, Ton -- Denarie, Jean -- Rosenberg, Charles -- Debelle, Frederic -- New York, N.Y. -- Science. 2004 Feb 27;303(5662):1361-4.

    NSP1 of the GRAS protein family is essential for rhizobial Nod factor-induced transcription (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-06-18
    Description: Rhizobial Nod factors induce in their legume hosts the expression of many genes and set in motion developmental processes leading to root nodule formation. Here we report the identification of the Medicago GRAS-type protein Nodulation signaling pathway 1 (NSP1), which is essential for all known Nod factor-induced changes in gene expression. NSP1 is constitutively expressed, and so it acts as a primary transcriptional regulator mediating all known Nod factor-induced transcriptional responses, and therefore, we named it a Nod factor response factor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smit, Patrick -- Raedts, John -- Portyanko, Vladimir -- Debelle, Frederic -- Gough, Clare -- Bisseling, Ton -- Geurts, Rene -- New York, N.Y. -- Science. 2005 Jun 17;308(5729):1789-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Science, Laboratory of Molecular Biology, Wageningen University, Wageningen 6703 HA, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15961669" target="_blank"〉PubMed〈/a〉
