Mechanisms regulating legume root nodule development are still poorly understood, and very few regulatory genes have been cloned and characterized. Here, we describe EFD (for ethylene response factor required for nodule differentiation), a gene that is upregulated during nodulation in Medicago truncatula. The EFD transcription factor belongs to the ethylene response factor (ERF) group V, which contains ERN1, 2, and 3, three ERFs involved in Nod factor signaling. The role of EFD in the regulation ...[more]

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

Project description: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. We used microarrays to detail the global programme of gene expression in response to Glutamine synthetase inhibition in root nodules and identified genes differentially expressed over a time course. Medicago truncatula nodulated plants (20 days post inoculation) were treated with 0.25 mM of PPT. Root nodules were harvested at 4, 8 and 24 hours after PPT application. As a control, root nodules collected just before PPT application were used (PPT 0h). Three biological replicates consisting of pools of root nodules harvested from five distinct plants were used for RNA extraction and hybridization on Affymetrix GeneChips.

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

Project description:We used laser-capture microdissection (LCM) to isolate specific cells from the Medicago truncatula nodule meristem (M), the distal infection (DIZ), the proximal infection zone (PIZ), infected cells (IC) and uninfected cells (UIC) from the fixation zone. Based on Medicago GeneChips, we identified the cell- and tissue-specific programm of gene expression in Medicago truncatula root nodules. Nodules were harvested three weeks after inoculation of Medicago truncatula (genotype Jemalong A17) plants with Sinorhizobium meliloti strain 2011. Nodules were fixed in Farmer's fixative and subsequently embedded in paraffin. 8 M-BM-5m de-paraffined sections were used to capture cells from the nodule meristem, distal infection zone, proximal infection zone, infected cells and uninfected cells from the fixation zone, using an Arcturus Pixcell II laser capture microscope. 3 biological replicates were used for each cell-/tissue type. After RNA extraction, the RNA was amplified and used for Medicago Gene Chip hybridization.

Identification of genes involved in the establishment of plant-microorganism interactions

Project description:affy_pathogen_medicago - In compatible interaction between plants and biotrophic microorganisms, neoformation of organs occurs to ensure an efficient relationship between both partners. During the interaction between Medicago truncatula and Sinorhizobium meliloti, bacteria induce the development of root nodule with a permanent meristem, and chronically infect plant cells from zone II before differentiating into atmospheric nitrogen fixing bacteroids. M. truncatula is also plant host for root-knot nematodes, such as Meloidogyne incognita. During this compatible pathogenic interaction, root-knot nematodes induce redifferenciation of root cells from the vascular cylinder into specialized feeding cells called “giant cells”. Hyperplasia and hypertrophy of the surrounding cells lead to the formation of typical root galls. This phenomenon invokes host pathways in common with those necessary for nitrogen-nodule formation, suggesting that nematode and rhizobia exploit a relative common strategy of plant cell infection at the cellular and molecular levels. In order to highlight key genes involved in gall and nodule developments, parallel laser microdissection of giant cells from galls and cells from zone II of nodules, followed by transcriptomic analysis, were performed. The RNA pools were extracted from these cells, amplified and used for transcriptomic studies with M. truncatula Affymetrix DNA chips. Keywords: organ comparison 12 arrays - Medicago infected with M. incognita or S. meliloti.
