Nod Factor Elicits Two Separable Calcium Responses in Medicago truncatula Root Hair Cells1

Modulation of intracellular calcium levels plays a key role in the transduction of many biological signals. Here, we characterize early calcium responses of wild-type and mutant Medicago truncatula plants to nodulation factors produced by the bacterial symbiont Sinorhizobium meliloti using a dual-dye ratiometric imaging technique. When presented with 1 nM Nod factor, root hair cells exhibited on...

Ethylene inhibits the Nod factor signal transduction pathway of Medicago truncatula
Plant Cell ; 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
Nod factor inhibition of reactive oxygen efflux in a host legume
Plant Physiology ; Hydrogen peroxide (H^sub 2^O^sub 2^) efflux was measured from Medicago truncatula root segments exposed to purified Nod factor and to poly-GalUA (PGA) heptamers. Nod factor, at concentrations > 100 pM, reduced H^sub 2^O^sub 2^ efflux rates to 60% of baseline levels beginning 20 to 30 min after

Peace Talks and Trade Deals. Keys to Long-Term Harmony in Legume-Microbe Symbioses
Plant Physiology ; Terrestrial autotrophs such as higher plants are confronted with challenges largely unknown to their counterparts in the seas, including extreme patchiness of inorganic nutrients. Evolution of higher plants has yielded interesting and important solutions to the problem of nutrient acquisition on
Mastoparan Activates Calcium Spiking Analogous to Nod Factor-Induced Responses in Medicago truncatula Root Hair Cells1[W][OA]
Plant Physiology ; 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
Pharmacological analysis of nod factor-induced calcium spiking in Medicago truncatula. Evidence for the requirement of type IIA calcium pumps and phosphoinositide signaling
Plant Physiology ; Pharmacological Analysis of Nod Factor-Induced Calcium Spiking in Medicago truncatula. Evidence for the Requirement of Type IIA Calcium Pumps and Phosphoinositide Signaling1 Bacterial Nod factors trigger a number of cellular responses in root hairs of compatible legume hosts, which include
Nod factor and elicitors activate different phospholipid signaling pathways in suspension-cultured alfalfa cells1
Plant Physiology ; Lipo-chitooligosaccharides (Nod factors) are produced by symbiotic Rhizobium sp. bacteria to elicit Nod responses on their legume hosts. One of the earliest responses is the formation of phosphatidic acid (PA), a novel second messenger in plant cells. Remarkably, pathogens have also been reported
Rhizobium nod factor perception and signalling
Plant Cell ; INTRODUCTION Biological nitrogen fixation is a process that can only be performed by certain prokaryotes. In some cases, such bacteria are able to fix nitrogen in a symbiotic relationship with plants. Bacteria of the genera Azorhizobium, Bradyrhizobium, Mesorhizobium, Rhizobium, and Sinorhizobium
The DMI1 and DMI2 Early Symbiotic Genes of Medicago truncatula Are Required for a High-Affinity Nodulation Factor-Binding Site Associated to a Particulate Fraction of Roots1
Plant Physiology ; The establishment of the legume-rhizobia symbiosis between Medicago spp. and Sinorhizobium meliloti is dependent on the production of sulfated lipo-chitooligosaccharidic nodulation (Nod) factors by the bacterial partner.
