Expression data of Medicago truncatula Jemalong A17 roots treated with auxin transport inhibitors

(Submitter supplied) Rhizobium and allied bacteria form symbiotic nitrogen-fixing nodules on legume roots. Plant hormones appear to play a role in nodule formation. We treated Medicago truncatula roots with auxin transport inhibitors (ATIs) N-(1-naphthyl)phthalamic acid (NPA) and 2,3,5-triiodobenzoic acid (TIBA) to induce the formation of pseudonodules. We compared the transcriptional responses of M. truncatula roots treated with ATIs to roots inoculated with Sinorhizobium meliloti. more...

Genes differentially expressed in wild-type Medicago truncatula plants during nodulation

(Submitter supplied) We used an Affymetrix oligonucleotide microarray consisting of 9,935 tentative consensus (TC)sequences, which are based on cDNA libraries (Mitra et al., 2004 [PMID:15220482]). We examined gene expression of wild-type M. truncatula plants after inoculation with wild-type S. meliloti at 1 d, 4 d, 7d, 14 d, and 21 d. We chose these time points because they span the range of development of the Rhizobium-legume symbiosis, from initiation of the interaction through nitrogen fixation. more...

Salt stress enhances early symbiotic gene expression in Medicago truncatula and induces a stress-specific set of rhizobium-responsive genes

(Submitter supplied) Salt stress is a major agricultural concern inhibiting not only plant growth but also the symbiotic association between legume roots and the soil bacteria rhizobia. This symbiotic association is initiated by a molecular dialogue between the two partners, leading to the activation of a signaling cascade in the legume host and ultimately the formation of nitrogen-fixing root nodules. Here we show that a moderate salt stress increases the responsiveness of early symbiotic genes in Medicago truncatula to its symbiotic partner, Sinorhizobium meliloti, while conversely, inoculation with S. more...

Reprogramming of root cells during nitrogen-fixing symbiosis entails dynamic polysome association of coding and non-coding RNAs

Cell- and tissue-specific transcriptome analyses of Medicago truncatula root nodules

Based on Medicago GeneChips, we identified the cell- and tissue-specific programm of gene expression in Medicago truncatula root nodules.

Expression data from wildtype Sinorhizobium meliloti Rm1021 and an hfq mutant

(Submitter supplied) The RNA-binding protein Hfq is a global regulator, which controls diverse cellular processes in bacteria. To begin understanding the role of Hfq in the Sinorhizobium meliloti-Medicago truncatula nitrogen-fixing symbiosis, we defined free-living and symbiotic phenotypes of an hfq mutant. Over 500 transcripts were differentially accumulated in the hfq mutant of S. meliloti Rm1021 when grown in a shaking culture.

Strigolactone biosynthesis requires the symbiotic GRAS-type transcription factors NSP1 and NSP2

(Submitter supplied) Legume GRAS-type transcription factors NSP1 and NSP2 are essential for Rhizobium Nod factor-induced nodulation. Both proteins are considered to be Nod factor response factors regulating gene expression upon symbiotic signalling. However, legume NSP1 and NSP2 can be functionally replaced by non-legume orthologs; including rice (Oryza sativa) OsNSP1 and OsNSP2. This shows that both proteins are functionally conserved in higher plants, suggesting an ancient function that was conserved during evolution. more...

Gene expression data from phosphinothricin (PPT) treated Medicago truncatula root nodules

(Submitter supplied) Nitrogen assimilation in plants is a tightly regulated process that integrates developmental and environmental signals. The legume-rhizobial symbiosis results in the formation of a specialized organ called root nodule, where the rhizobia fixes atmospheric nitrogen into ammonia. Ammonia is assimilated by the plant enzyme glutamine synthetase, which is specifically inhibited by PPT. The expression of key genes related to the regulation of root nodule metabolism will likely be affected by glutamine synthetase inhibition. more...

Identification of putative H2O2 regulated genes during the establishment of the Sinorhizobi...

(Submitter supplied) The involvement of ROS in the legume – Rhizobium symbiotic interaction has been highlighted (Santos et al., 2001; Rubio et al., 2004). This interaction is characterized by the formation of a new organ on the root, the nodule and by the penetration, in parallel, of the bacteria into the root tissue via an infection thread (IT) (Parniske and Downie, 2003; Gage, 2004). H2O2 production has been shown in ITs during the Medicago – Sinorhizobium meliloti interaction (Santos et al., 2001). more...

A Ca2+/calmodulin-dependent protein kinase required for symbiotic nodule development: Gene identification by transcript-based cloning

(Submitter supplied) Trancript Based Cloning (TBC) uses standard Gene Expression techniques to quickly isolate genes of interest and begin to determine their function. Using a particular mutant phenotype, identified during a programme of mutagenesis and screning, and a wild-type control we can quickly determine a list of genes that is likely to contain the gene responsible for the phenotype. TBC is a general method for identifying and cloning important plant genes that is fast and may be applicable to almost any plant species Transcript abundance assays on the barley rar1-2 mutant and Sultan5 wild type were performed by using standard methods for the Affymetrix barley genome array (Affymetrix). more...

Influence of Nod Factors on early developmental stages of root development in Medicago truncatula

(Submitter supplied) We would like to know how symbiotic molecules such as Nod Factors (NF) influence lateral root (LR) development in M. truncatula. We have preliminary evidence that this action is through early stages of root development. Auxin is the major phytohormone controlling LR development and we also have evidence that NF interfere with auxin for the control of LR development. This transcriptomic study aims at finding new molecular targets that would be responsive to auxin and NF treatment, even at a higher level by the combination of both auxin and NF. more...

Gene expression response in roots of Medicago truncatula mutants treated with Myc-LCOs

(Submitter supplied) Legumes interact with soil fungi, leading to the development of arbuscular mycorrhizal (AM) roots. Diffusible AM fungal signals were identified as sulphated and non-sulphated LCOs (sMyc-LCOs and nsMyc-LCOs). Applying Myc-LCOs on roots of symbiotic mutants, we used GeneChips to detail the global programme of gene expression in these mutants in response to the external application of Myc-LCOs.
