Ethylene inhibits the Nod factor signal transduction pathway of Medicago truncatula.
Legumes form a mutualistic symbiosis with bacteria collectively referred to as rhizobia. The bacteria induce the formation of nodules on the roots of the appropriate host plant, and this process requires the bacterial signaling molecule Nod factor. Although the interaction is beneficial to the plant, the number of nodules is tightly regulated. The gaseous plant hormone ethylene has been shown t...
متن کاملRoot-knot nematodes and bacterial Nod factors elicit common signal transduction events in Lotus japonicus.
The symbiosis responsible for nitrogen fixation in legume root nodules is initiated by rhizobial signaling molecules [Nod factors (NF)]. Using transgenically tagged microtubules and actin, we dynamically profiled the spatiotemporal changes in the cytoskeleton of living Lotus japonicus root hairs, which precede root-hair deformation and reflect one of the earliest host responses to NF. Remarkabl...
متن کاملNod proteins link bacterial sensing and autophagy.
Autophagy is one of the main cellular degradation systems in eukaryotes, responsible for the elimination of long-lived proteins and damaged organelles. Besides its well-documented role as a housekeeping mechanism, autophagy has recently caught the attention of groups working in the fields of microbiology and immunology, especially those working in innate immunity. In particular, the highly spec...
متن کاملAn ERF transcription factor in Medicago truncatula that is essential for Nod factor signal transduction.
Rhizobial bacteria activate the formation of nodules on the appropriate host legume plant, and this requires the bacterial signaling molecule Nod factor. Perception of Nod factor in the plant leads to the activation of a number of rhizobial-induced genes. Putative transcriptional regulators in the GRAS family are known to function in Nod factor signaling, but these proteins have not been shown ...
متن کاملSignal Transduction by a Fungal NOD-Like Receptor Based on Propagation of a Prion Amyloid Fold
In the fungus Podospora anserina, the [Het-s] prion induces programmed cell death by activating the HET-S pore-forming protein. The HET-s β-solenoid prion fold serves as a template for converting the HET-S prion-forming domain into the same fold. This conversion, in turn, activates the HET-S pore-forming domain. The gene immediately adjacent to het-S encodes NWD2, a Nod-like receptor (NLR) with...
