Beschreibung:
In terrestrial ecosystems, plants take up phosphate predominantly via association with arbuscular mycorrhizal fungi (AMF). We identified loss of responsiveness to AMF in the rice (Oryza sativa) mutant hebiba, reflected by the absence of physical contact and of characteristic transcriptional responses to fungal signals. Among the 26 genes deleted in hebiba, DWARF 14 LIKE is, the one responsible for loss of symbiosis . It encodes an alpha/beta-fold hydrolase, that is a component of an intracellular receptor complex involved in the detection of the smoke compound karrikin. Our finding reveals an unexpected plant recognition strategy for AMF and a previously unknown signaling link between symbiosis and plant development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gutjahr, Caroline -- Gobbato, Enrico -- Choi, Jeongmin -- Riemann, Michael -- Johnston, Matthew G -- Summers, William -- Carbonnel, Samy -- Mansfield, Catherine -- Yang, Shu-Yi -- Nadal, Marina -- Acosta, Ivan -- Takano, Makoto -- Jiao, Wen-Biao -- Schneeberger, Korbinian -- Kelly, Krystyna A -- Paszkowski, Uta -- PDAG/223 T39/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2015 Dec 18;350(6267):1521-4. doi: 10.1126/science.aac9715.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Molecular Biology, University of Lausanne, Biophore Building, 1015 Lausanne, Switzerland.
