    LysM-type mycorrhizal receptor recruited for rhizobium symbiosis in nonlegume Parasponia (2011)

    Beschreibung: Rhizobium-root nodule symbiosis is generally considered to be unique for legumes. However, there is one exception, and that is Parasponia. In this nonlegume, the rhizobial nodule symbiosis evolved independently and is, as in legumes, induced by rhizobium Nod factors. We used Parasponia andersonii to identify genetic constraints underlying evolution of Nod factor signaling. Part of the signaling cascade, downstream of Nod factor perception, has been recruited from the more-ancient arbuscular endomycorrhizal symbiosis. However, legume Nod factor receptors that activate this common signaling pathway are not essential for arbuscular endomycorrhizae. Here, we show that in Parasponia a single Nod factor-like receptor is indispensable for both symbiotic interactions. Therefore, we conclude that the Nod factor perception mechanism also is recruited from the widespread endomycorrhizal symbiosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Op den Camp, Rik -- Streng, Arend -- De Mita, Stephane -- Cao, Qingqin -- Polone, Elisa -- Liu, Wei -- Ammiraju, Jetty S S -- Kudrna, Dave -- Wing, Rod -- Untergasser, Andreas -- Bisseling, Ton -- Geurts, Rene -- New York, N.Y. -- Science. 2011 Feb 18;331(6019):909-12. doi: 10.1126/science.1198181.

    LysM domain receptor kinases regulating rhizobial Nod factor-induced infection (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2003-08-30
    Beschreibung: The rhizobial infection of legumes has the most stringent demand toward Nod factor structure of all host responses, and therefore a specific Nod factor entry receptor has been proposed. The SYM2 gene identified in certain ecotypes of pea (Pisum sativum) is a good candidate for such an entry receptor. We exploited the close phylogenetic relationship of pea and the model legume Medicago truncatula to identify genes specifically involved in rhizobial infection. The SYM2 orthologous region of M. truncatula contains 15 putative receptor-like genes, of which 7 are LysM domain-containing receptor-like kinases (LYKs). Using reverse genetics in M. truncatula, we show that two LYK genes are specifically involved in infection thread formation. This, as well as the properties of the LysM domains, strongly suggests that they are Nod factor entry receptors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Limpens, Erik -- Franken, Carolien -- Smit, Patrick -- Willemse, Joost -- Bisseling, Ton -- Geurts, Rene -- New York, N.Y. -- Science. 2003 Oct 24;302(5645):630-3.

    NSP1 of the GRAS protein family is essential for rhizobial Nod factor-induced transcription (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2005-06-18
    Beschreibung: 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〉
