Natural variation of root exudates in Arabidopsis thaliana-linking metabolomic and genomic data

ABSTRACT: The 19 parent lines of the Arabidopsis thaliana MAGIC collection show significant differences in their root exudate profiles. Changes in metabolism were analyzed by ultra-performance liquid chromatography coupled to electrospray ionization quadrupole time–of–flight mass spectrometry (UPLC-ESI-QTOF-MS) untargeted in positive and negative mode, and targeted for a set of known metabolites.

INSTRUMENT(S): micrOTOF-Q I ESI-Qq-TOF (Bruker)

Many metabolomics studies focus on aboveground parts of the plant, while metabolism within roots and the chemical composition of the rhizosphere, as influenced by exudation, are not deeply investigated. In this study, we analysed exudate metabolic patterns of Arabidopsis thaliana and their variation in genetically diverse accessions. For this project, we used the 19 parental accessions of the Arabidopsis MAGIC collection. Plants were grown in a hydroponic system, their exudates were harvested be ...[more]

Linking root exudates to functional plant traits

Project description:Primary and secondary metabolites exuded by plant roots have mainly been studied under laboratory conditions, while knowledge of root exudate patterns of plants growing in natural communities is very limited. Focusing on ten common European grassland plant species, we asked to which degree exuded metabolite compositions are specific to species or growth forms (forbs and grasses), depend on environments and local neighbourhoods, and reflect traditional plant functional traits. Root exudates were collected under field conditions and analysed using a non-targeted gas chromatography coupled mass spectrometry (GC-MS) approach. In total, we annotated 153 compounds of which 36 were identified by structure and name as metabolites mainly derived from the primary metabolism. Here we show by using variance partitioning, that the composition of exuded polar metabolites was mostly explained by plot identity, followed by plant species identity while plant species composition of the local neighbourhood played no role. Total and root dry biomass explained the largest proportion of variance in exudate composition, with additional variance explained by traditional plant traits. Although the exudate composition was quite similar between the two growth forms, we found some metabolites that occurred only in one of the two growth forms. Our study demonstrated the feasibility of measuring polar exudates under non-sterile field conditions by mass spectrometry, which opens new avenues of research for functional plant ecology.

Root transcriptomes for the 19 parents of the Arabidopsis thaliana MAGIC lines

Project description:We produced RNA-Seq reads from messenger RNA isolated from root tissue for the 19 MAGIC founder accessions (inbred strains) of Arabidopsis thaliana (see Gan et al. 2011. Nature 477:419-23 for a description of the MAGIC genetic mapping resource). The read data was generated with biological replication (two replicates). The resulting RNA-Seq data provide a resource to assess root gene expression across different accessions of A. thaliana. Comparable RNA-Seq read data for the MAGIC founder accessions for aerial seedling tissue has previously been released under GEO series GSE30720 (Gan et al. 2011. Nature, 477:419-23).

Semi‐polar root exudates in natural grassland communities

Project description:In the rhizosphere, plants are exposed to a multitude of different biotic and abiotic factors, to which they respond by exuding a wide range of secondary root metabolites. So far, it has been unknown to which degree root exudate composition is species-specific and is affected by land use, the local impact and local neighborhood under field conditions. In this study, root exudates of 10 common grassland species were analyzed, each five of forbs and grasses, in the German Biodiversity Exploratories using a combined phytometer and untargeted liquid chromatography-mass spectrometry (LC-MS) approach. Redundancy analysis and hierarchical clustering revealed a large set of semi-polar metabolites common to all species in addition to species-specific metabolites. Chemical richness and exudate composition revealed that forbs, such as Plantago lanceolata and Galium species, exuded more species-specific metabolites than grasses. Grasses instead were primarily affected by environmental conditions. In both forbs and grasses, plant functional traits had only a minor impact on plant root exudation patterns. Overall, our results demonstrate the feasibility of obtaining and untargeted profiling of semi-polar metabolites under field condition and allow a deeper view in the exudation of plants in a natural grassland community.
