Molecular Signals Controlling the Inhibition of Nodulation by Nitrate in Medicago truncatula
The presence of nitrogen inhibits legume nodule formation, but the mechanism of this inhibition is poorly understood. We found that 2.5 mM nitrate and above significantly inhibited nodule initiation but not root hair curling in Medicago trunatula. We analyzed protein abundance in M. truncatula roots after treatment with either 0 or 2.5 mM nitrate in the presence or absence of its symbiont Sinor...
متن کاملMultiple Autoregulation of Nodulation (AON) Signals Identified through Split Root Analysis of Medicago truncatula sunn and rdn1 Mutants
Nodulation is energetically costly to the host: legumes balance the nitrogen demand with the energy expense by limiting the number of nodules through long-distance signaling. A split root system was used to investigate systemic autoregulation of nodulation (AON) in Medicago truncatula and the role of the AON genes RDN1 and SUNN in the regulatory circuit. Developing nodule primordia did not trig...
متن کاملTranscript analysis of early nodulation events in Medicago truncatula.
Within the first 72 h of the interaction between rhizobia and their host plants, nodule primordium induction and infection occur. We predicted that transcription profiling of early stages of the symbiosis between Medicago truncatula roots and Sinorhizobium meliloti would identify regulated plant genes that likely condition key events in nodule initiation. Therefore, using a microarray with abou...
متن کاملAbscisic acid coordinates nod factor and cytokinin signaling during the regulation of nodulation in Medicago truncatula.
Nodulation is tightly regulated in legumes to ensure appropriate levels of nitrogen fixation without excessive depletion of carbon reserves. This balance is maintained by intimately linking nodulation and its regulation with plant hormones. It has previously been shown that ethylene and jasmonic acid (JA) are able to regulate nodulation and Nod factor signal transduction. Here, we characterize ...
متن کاملIN BRIEF Medicago truncatula CRE1 Cytokinin Receptor Regulates Nodulation and Lateral Root Development
The plant hormone cytokinin is implicated in the control of root architecture and development, including legume root nodulation. Gonzalez-Rizzo et al. (pages 2680–2693) identified a Medicago truncatula homolog of Arabidopsis, CYTOKININ RESPONSE1 (CRE1), which encodes a cytokinin receptor histidine kinase, and made use of RNA interference of Mt CRE1 to investigate the role of cytokinin in the no...
