Extracellular adenosine 5'-triphosphate (ATP) is an essential signaling molecule that is perceived in mammals by plasma membrane P2-type purinoceptors. Similar ATP receptors do not exist in plants, although extracellular ATP has been shown to play critical roles in plant growth, development, and stress responses. Here, we identify an ATP-insensitive Arabidopsis mutant, dorn1 (Does not Respond to Nucleotides 1), defective in lectin receptor kinase I.9 (Arabidopsis Information Resource accession c ...[more]

Cell type-specific transcriptional responses of Arabidopsis to salinity

Project description:Microarray data were generated to investigate the changes in gene expression for two cell types of the root: pericycle and cortical cells in response to salt treatment. The transcription profile of both cell types were also generated. Cell-types of interest expressing specifically Green Fluorescent Protein (GFP) were isolated from the rest of the root using fluorescence-activated cell sorting (FACS). 11 arrays were generated from plants grown in control and salt conditions. All seedlings grew in one tank were collected and correspond to one biological sample. Two control biological replicates were used for pericycle and 3 for cortical cells. By comparison from control microarray, 6 others arrays from salt treated plant (3 for each cell types) were used to identified salt responsive genes. The salt treatment was done on day 6 and 7 with increment of 25mM every 24h.

Bone marrow-derived and resident liver macrophages display unique transcriptomic signatures but similar biological functions

Project description:Liver macrophages play a major role in the control of infections in the liver and in the pathology associated with chronic liver diseases. It was recently shown that liver macrophages can have two different origins, however, the extent to which these populations are functionally distinct remains to be fully addressed. In this study, we compare the gene expression profile of liver resident and bone marrow derived liver macrophages in mouse, 6 weeks after total body irradiation and bone marrow transplantation.

Transcriptome analysis of transgenic plants with ectopic expression (driven by 35S promoter) of At14a-Like1 (AFL1, At3g28270) YFP fusion protein.

Project description:Transcriptome analysis was used to identify genes differentially expressed in transgenic plants expressing At14a-Like1 (AFL1, At3g28270)) YFP fusion protein compared to wild type. Transcriptome analysis was performed using seedlings grown under either control conditions or low water potential stress with the objective of identifying genes associated with the increased growth caused by AFL1 overexpression under stress. The analysis identified 172 genes up-regulated and 525 genes down regulated in 35S:AFL1-YFP relative to wild type in control condtions. In the stress treatment 398 genes were up regulated and 722 down regulated in 35S:AFL1-YFP plants relative to wild type. The criteria used to identify up and down regulated genes was fold change greater than 1.5 and corrected p value M-bM-^IM-$0.05. Wild type (Col-0) or transgenic Arabidopsis thaliana seedlings were germinated on agar plates and after seven days of growth, seedlings were transferred either to fresh plates of control media or to low water potential (-1.2 MPa) stress plates. Samples were collected 10 h after transfer.

Impact of rhamnolipids (RLs), natural defense elicitors, on shoot and root proteomes of Brassica napus by a Tandem Mass tags (TMTs) labeling approach

Project description:The rapeseed crop (Brassica napus) is valued mainly for animal feed, food oil and biofuel production. This plant is particularly susceptible to many pathogens like parasitic plants, fungi or animals attacking aerial or root parts. Conventional plant protection products, used intensively in agriculture, have a negative impact on the environment (air and water quality, biodiversity, etc.) as well as on human health. There is therefore a growing demand for the development of new, more planet-friendly alternative protection methods such as biocontrol compounds. Natural rhamnolipids (RLs) can be used as elicitors of plant defense mechanisms. Indeed, these glycolipids, from bacteria secretome, are biodegradable, non-toxic and they are known for their stimulating and protective effects, in particular on rapeseed against filamentous fungi. Characterizing the organ responsiveness to defense stimulating compounds like RLs is missing. This analysis is crucial in the frame of optimizing the effectiveness of RLs against various diseases. A TMT labeling of the proteins extracted from the shoots and roots of B. napus has been performed and showed a differential pattern of protein abundance between them. These results have allowed identifying several protein families possibly involved in the differential responses observed in shoots and roots of rapeseed upon RLs treatment. In particular, quantitative proteomic analysis highlighted differential accumulation of parietal and cytoplasmic defense or stress proteins in response to treatments with RLs with a clear effect of the type of application (foliar spraying or root absorption). These results must be considered for further use of RLs to fight specific rapeseed pathogens.

Identification of PM-localized proteins

Project description:In order to assess the quality of alleged PM identifications from Arabidopsis, PM-enriched fractions were compared to PM-depleted fractions using 18O isotopic labeling and mass spectrometry. The two samples submitted are biological replicates. Keywords: Protein Localization via MS Two biological replicates were analyzed in order to assess sample complexity. PM-derived vesicles were digested in 18O water and compared to PM-depleted fractions digested in 16O (natural abundance) water. Relative ion intensities were then used to calculate a heavy/lite ratio with proteins showing enrichment in the upper phase having a ratio greater than 1 or 0 on a log2 scale.

Control, low water potential (drought) stress and stress release transcriptome analysis of mutants impaired in proline (Delta1-pyrroline-5-carboxylate synthase1-4; p5cs1-4) or abscisic acid (aba2-1) synthesis.

Project description:mRNA sequencing was used to identify genes differentially expressed in Delta1-pyrroline-5-carboxylate synthase1-4 (p5cs1-4) mutants deficient in low water potential-induced proline accumulation and the Abscisic Acid (ABA) deficient mutant aba2-1 compared to Col-0 wild type. Three treatments were analyzed for each genotype: unstressed control, a 96 hour low water potential (-1.2 MPa) treatment and a stress-release treatment where seedlings were removed from the stress treatment and transferred back to control media for 10 hours. Approximately 100 genes were found to be significantly up-regulated in p5cs1-4 compared to wild type in both the control and stress treatments with an equal number down regulated. There was also a substantial transcription response to the stress release treatment which varied between wild type, p5cs1-4 and aba2-1. Wild type (Col-0), p5cs1-4 and aba2-1 Arabidopsis thaliana seedlings were germinated on agar plates and after seven days of growth, seedlings were transferred either to fresh plates of control media or to low water potential (-1.2 MPa) stress plates. Samples were collected 96 h after transfer (Control and stress treatments). At 96 h, additional seedlings were transferred from the stress treatment back to control agar plates and samples collected 10 h after this stress release. Three independent biological experiments and mRNA extractions were performed for each genotype/treatment (27 mRNA extractions. After quality check and quantitation, the mRNA samples were pooled to produce a set of 9 samples for sequencing.

Gene regulation by the seed maturation master regulators, LEC1, LEC2, FUS3 and ABI3 [set 2]

Project description:During seed maturation, the embryo accumulates nutrition storage compounds such as oil and reserve proteins, and acquires dormancy and desiccation tolerance. Arabidopsis transcription factors LEC1, LEC2, FUS3 and ABI3 are known as the master regulators of seed maturation because all these events during the seed maturation are severely affected by the respective mutants. In addition, the lec1, lec2 and fus3 mutants exhibit some heterochronic characteristics, as exemplified by the development of true leaf-like cotyledons during embryogenesis. To characterize these mutants at the whole genome expression level, microarray experiments were performed. Developing seeds were dissected from the siliques of the abi3-6 homozygous plants or the respective wild type plants (Col-0) at 12 and 16 days after flowering. Seeds samples were obtained from triplicate batches of plants and used for RNA preparation.
