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...

MetabolomicsMetabolomic analysis of alfalfa (Medicago sativa L.) root-symbiotic rhizobia responses under alkali stress
Alkaline salts (e.g., NaHCO3 and Na2CO3) causes more severe morphological and physiological damage to plants than neutral salts (e.g., NaCl and Na2SO4) due to differences in pH. The mechanism by which plants respond to alkali stress is not fully understood, especially in plants having symbotic relat...

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...

ProteomicsComparative proteomics analysis of root and nodule mitochondria of soybean
Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bactero...

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...

MetabolomicsRoot hair developmental regulators orchestrate drought induced microbiome changes and affect the interactions with stress alleviating Rhizobiaceae

Drought is one of the most severe abiotic stresses. However, there is a lack of genetic evidence regarding whether and how plants coordinate the dynamic assembly of the microbiome in response to drought. Through the use of mutants with enhanced or reduced root hair densities (rsl2 rsl4, hairless ...

MetabolomicsUntargeted metabolomic analysis of Stylosanthes guianensis roots and nodules following Bradyrhizobium inoculation in acidic soil
Prior to transplantation into acidic soil, 30-day-old Stylosanthes guianensis seedlings were inoculated with Bradyrhizobium (Br) strain LZ3-2. Sixty days after transplantation, root and nodule samples were collected, flash-frozen in liquid nitrogen, and stored at negative 80 degrees Celsius for subs...
