Methylation Changes in Soybean Early Maturation Seed Compartments Using Laser Capture Microdissection (LCM)

Project description:What methylation changes are occurring in different compartments of early maturation stage seed largely remains unknown. To uncover the possible role of DNA methylation in different compartments of early maturation stage seed, we characterized the methylome of two major compartments (abaxial parenchyma and adaxial parenchyma) in embryonic cotyledon, four major compartments (parenchyma, plumule, root tip, and vascular) in embryonic axis, and seed coat layers (parenchyma and palisade) using Illumina sequencing. The whole seed coat and embryonic cotyledons were captured using LCM to serve as controls.

Large-scale transcriptomics provides insights on the mycorrhizal symbiosis of the Mediterranean orchid Limodorum abortivum in nature

Project description:The study of orchid mycorrhizal interactions is particularly complex because of the peculiar life cycle of these plants and their diverse trophic strategies. Here, large-scale transcriptomics has been applied to investigate gene expression in the mycorrhizal roots of the terrestrial mixotrophic orchid Limodorum abortivum under natural conditions. Our results provide new insights into the mechanisms underlying plant-fungus interactions in orchids and in particular on the plant responses to the mycorrhizal symbiont(s) in adult roots. Comparison with gene expression in mycorrhizal roots of another orchid species, Oeceoclades maculata, suggests that amino acids may represent the main nitrogen source in both protocorms and adult orchids, at least for mixotrophic species. The upregulation, in mycorrhizal L. abortivum roots, of some symbiotic molecular marker genes identified in mycorrhizal roots from other orchids as well as in arbuscular mycorrhiza, suggests a common plant core of genes in endomycorrhizal symbioses. Further efforts will be required to understand whether the specificities of orchid mycorrhiza depend on fine-tuned regulation of these common components, or whether specific additional genes are involved.

Laser Capture Microdissection of Hyperlipidemic Mouse Aorta Atherosclerosis

Project description:Atherosclerosis is a transmural chronic inflammatory condition of small and large arteries that is associated with adaptive immune responses at all disease stages. However, impacts of adaptive immune reactions on clinically apparent atherosclerosis such as intima lesion (plaque) rupture, thrombosis, myocardial infarction, and aneurysm largely remain to be identified. It is increasingly recognized that leukocyte infiltrates in plaque, media, and adventitia are distinct but their specific roles have not been defined. To map these infiltrates, we employed laser capture microdissection (LCM) to isolate the three arterial wall laminae using apoE-/- mouse aorta as a model. RNA from LCM-separated tissues was extracted and large scale whole genome expression microarrays were prepared. We observed that the quality of the resulting gene expression maps was compromised by tissue RNA carried over from adjacent laminae during LCM. To account for these flaws, we established quality controls and algorithms to improve the predictive power of LCM-derived microarray data. Our approach creates robust transcriptome atlases of normal and atherosclerotic aorta. Assessing LCM transcriptomes for immunity-related mRNAs indicated markedly distinctive gene expression patterns in the three laminae of the atherosclerotic aorta. These mouse mRNA expression data banks can now be mined to address a wide range of questions in cardiovascular biology.

Gene expression changes in Oidiodendron maius- Vaccinium myrtillus mycorrhizal roots compared to Oidiodendron maius free-living mycelium

Project description:Illumina HiSeq technology was used to generate mRNA profiles from Oidiodendron maius mycorrhizal roots compared to free-living mycelium . Mycorrhizal roots and control mycelium were harvested after 45 days and used for RNA extraction. Reads of 2X100bp were generated and aligned to Oidiodendron maius transcripts (http://genome.jgi-psf.org/Oidma1) using CLC Genomics Workbench 6. mRNA profiles from Oidiodendron maius mycorrhizal roots and free-living mycelium were generated by paired-end (2x100bp) Illumina HiSeq2000 sequencing. Three biological replicates were sequenced for mycorrhizal and mycelium samples.

Root and leaf metabolome of non-mycorrhizal and mycorrhizal seedlings by UHPLC-Orbitrap-MS/MS

Project description:This study compared mycorrhizal-associated metabolome alterations across multiple plant-mycorrhizal fungus combinations. Specifically, we inoculated a phylogenetically diverse set of temperate tree species with either arbuscular mycorrhizal or ectomycorrhizal fungi (the two major mycorrhizal lifestyles). Using comprehensive metabolomics approaches, we then assessed the metabolome in mycorrhizal and non-mycorrhizal roots and the corresponding leaves.

Gene expression data from arbuscular mycorrhizal and phosphate-treated Medicago truncatula roots.

Project description:Arbuscular mycorrhiza (AM) interactions between plants and Glomeromycota fungi primarily support phosphate aquisition of most terrestrial plant species. To unravel gene expression in Medicago truncatula root colonization by AM fungi, we used genome-wide transcriptome profiling based on whole mycorrhizal roots. We used GeneChips to detail the global programme of gene expression in response to colonization by arbuscular mycorrhizal fungi and in response to a treatment with phosphate and identified genes differentially expressed during this process. Medicago truncatula roots were harvested at 28 days post inoculation with the two different arbuscular mycorrhizal fungi Glomus intraradices (Gi-Myc) and Glomus mosseae (Gm-Myc) under low phosphate conditions (20 µM phosphate) or after a 28 days treatment with 2 mM phosphate in the absence of arbuscular mycorrhizal fungi (2mM-P). As a control, uninfected roots grown under low phosphate conditions (20 µM phosphate) were used (20miM-P). Three biological replicates consisting of pools of five roots were used for RNA extraction and hybridization on Affymetrix GeneChips.

Proteomic and transcriptomic analyses indicate metabolic changes and reduced defense responses in mycorrhizal roots of Oeceoclades maculata (Orchidaceae) collected in nature

Project description:Orchids form an endomycorrhizal association with fungal symbionts mainly belonging to Basidiomycetes. The molecular events taking place in orchid mycorrhiza are poorly understood, although the cellular changes necessary to accommodate the fungus and to control nutrient exchange between the symbionts imply a modulation of gene expression. In this study, we used proteomic and transcriptomic approaches to identify changes in the steady-state levels of proteins and transcripts in roots of the green terrestrial orchid Oeceoclades maculata. When mycorrhizal and non-mycorrhizal roots from the same individuals of O. maculata were compared, 94 proteins showed differential accumulation using the label-free protein quantitation approach, 86 using isobaric tagging (iTRAQ) and 60 using 2D-differential electrophoresis. After de novo assembly of transcriptomic data, 11,179 plant transcripts were found to be differentially expressed and 2175 were successfully annotated. The annotated plant transcripts allowed the identification of up- and down-regulated metabolic pathways in mycorrhizal roots, as compared to non-mycorrhizal roots. Overall, proteomics and transcriptomics revealed in mycorrhizal roots increased levels of transcription factors and nutrient transporters, as well as ethylene-related proteins. The expression pattern of proteins and transcripts involved in plant defense responses suggest that plant defense is reduced in mycorrhizal roots. These results expand our current knowledge towards a better understanding of the orchid mycorrhizal symbiosis in adult plants under natural conditions.
