MetabolomicsMetabolome of the Medicago truncatula symbiosome space, bacteroid, and nodule cytosol
This study characterizes the metabolome of the Medicago truncatula-Sinorhizobium meliloti symbiosis. Symbiosome space, bacteroid, and nodule cytosol fractions were isolated from 4-week-old root nodules and profiled by untargeted liquid chromatography-tandem mass spectrometry (LC-MS/MS). Polar metabo...

TranscriptomicsHigh-throughput sequencing of small RNAs in Medicago truncatula
Medicago truncatula endogenous small RNAs The dataset contains Medicago truncatula Gaertn. cv. Jemalong endogenous small RNA sequences in the range 18-28 nucleotides. High-throughput Solexa/Illumina sequencing was carried out at the Sainsbury Laboratory, Norwich, UK. Please see www.illumina.com for...

TranscriptomicsHigh-throughput pyrosequencing of miRNAs from Medicago truncatula nodules and roots
We have used deep sequencing of small RNAs from nodules and root apexes of the model legume Medicago truncatula, to identify 113 novel candidate miRNAs. These miRNAs (legume or Mt-specific) are encoded by 278 putative hairpin precursors in the M. truncatula genome. Several miRNAs are differentially ...

TranscriptomicsCell- and tissue-specific transcriptome analyses of Medicago truncatula root nodules
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...

TranscriptomicsGene expression data from phosphinothricin (PPT) treated Medicago truncatula root nodules
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 assimilate...

TranscriptomicsmicroRNA profiling of root tissues and root forming explant cultures in Medicago truncatula
To identify key miRNAs involved in root meristem formation in M. truncatula, deep sequencing was used to compare the miRNA populations dreived from four tissues. These were; root tip tissue, containing the root apical meristem, elongation zone tissue, root forming callus tissue and non-root formi...

TranscriptomicsTranscription profiling of seed coat of Medicago truncatula 10-36 days after pollination
Genes specifically or induced in seed coat of Medicago truncatula 10-36 days after pollination were identified by comparing with genes expressed in other organs.

TranscriptomicsTranscription profiling of Medicago truncatula time series of flower and pod development
To study the development of flowers and pods in Medicago truncatula, eight stages of flower and pod development (designated F1-F4 and P1-P4, respectively) were chosen for tissue harvesting. As a common reference, young but already fully developed leaves (corresponding to the third-distant node from ...

TranscriptomicsExpression data of Medicago truncatula Jemalong A17 roots treated with S. meliloti exoA mutant or auxin transport inhibitors
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 indu...
