Transcription profiling of Arabidopsis mutants mpk4 and ctr1

ABSTRACT: Arabidopsis MPK4 is involved in the control of antagonism between salicylic acid (SA) and ethylene (ET)/jasmonic acid (JA) pathways in the plant innate immune system as a repressor of the SA pathway, but an activator of the ET/JA pathway. Here we and use comparative microarray analysis of ctr1, ctr1/mpk4, mpk4 and wild type to show that MPK4 is required for only a narrow subset of ET regulated genes.

Arabidopsis systemic immunity uses conserved defense signaling pathways and is mediated by jasmonates.

Truman William W Bennett Mark H MH Kubigsteltig Ines I Turnbull Colin C Grant Murray M

Proceedings of the National Academy of Sciences of the United States of America 20070110 3

In the absence of adaptive immunity displayed by animals, plants respond locally to biotic challenge via inducible basal defense networks activated through recognition and response to conserved pathogen-associated molecular patterns. In addition, immunity can be induced in tissues remote from infection sites by systemic acquired resistance (SAR), initiated after gene-for-gene recognition between plant resistance proteins and microbial effectors. The nature of the mobile signal and remotely activ ...[more]

Transcription profiling of Arabidopsis wild type, 35S:mks1 and mpk4 plants

Project description:In plants, MAPKs are implicated in signalling cascades regulating immediate as well as systemic responses to pathogens. Arabidopsis MAP kinase 4 (MPK4) negatively regulates systemic acquired resistance (SAR) accompanied by the expression of pathogenesis-related (PR) genes. MPK4 interacts with and phosphorylates MKS1. Plants that over-express MKS1 exhibit constitutive SAR. RNA was independently isolated three times from each of the three genotypes, wild-type, mpk4 and 35S:mks1 and hybridized to nine Affymetrix ATH1 GeneChips.

Frequent in-frame somatic deletions activate gp130 in inflammatory hepatocellular tumours

Project description:Inflammatory hepatocellular adenomas (IHCA) are benign liver tumours defined by the presence of inflammatory infiltrates and by the elevated expression of inflammatory proteins in tumour hepatocytes1,2. Here we show a striking activation of the IL6 signalling pathway in this tumour type, and sequencing candidate genes pinpointed this response to somatic gain-of-function mutations in the IL6ST gene that encodes the signalling co-receptor gp130. Indeed, ~70% of IHCA harbour small in-frame deletions that target the binding site of gp130 for IL6, and expression of the most frequent gp130 mutant, Delta-STVY190, in hepatocellular cells activates STAT3 in absence of ligand. Further, analysis of hepatocellular carcinomas revealed rare gp130 alterations always accompanied by M-CM-^_-catenin-activating mutations, suggesting a cooperative effect of these signalling pathways in the malignant conversion of hepatocytes. The recurrent gain-of-function gp130 mutations in these human hepatocellular adenomas explains their inflammatory phenotype, and suggest that similar alterations may occur in other inflammatory epithelial tumours with STAT3 activation. HG-U133A Affymetrix GeneChipTM arrays were used to compare the expression profiles of 4 Inflammatory hepatocellular adenomas (IHCA) and 4 non related non-tumor livers. RNA labelling, hybridization and analysis were carried out following the manufacturerM-bM-^@M-^Ys instructions (Affymetrix, Santa Clara, CA). Raw data were obtained by using Microarray Suite 5.0 (MAS5) software, embedded in the Affymetrix GeneChip Operating Software (Santa Clara, USA); the resulting raw numerical data (CEL files) - available as supplementary files - collected from 8 Affymetrix GeneChips were pre-processed for normalization and filtering as described in [Rebouissou et al., J Biol Chem 2007, 282(19):14437-46, PMID: 17379603; Rebuissou et al., J Hepatol 2008, 49(1):61-71.

MPK4 phosphorylation dynamics and interacting proteins in plant immunity

Project description:The Arabidopsis MAP kinase 4 (MPK4) has been proposed as negative player in plant immunity, but it is activated by pathogen-associated molecular patterns (PAMPs), such as flg22. The molecular mechanisms by which MPK4 is activated and controls plant defense remain elusive. In this study, we investigated the Arabidopsis defense against a bacterial pathogen Pseudomonas syringae pv. tomato (Pst) DC3000 when the MPK4 is overexpressed. We showed an increase in pathogen resistance and suppression of jasmonic acid (JA) signaling in the MPK4 overexpressing (OE) plants. We also showed that the OE plants are very sensitive to flg22-triggered reactive oxygen species (ROS) burst in guard cells, which resulted in an enhanced stomatal closure, compared to wild-type (WT). During the flg22 activation, dynamic phosphorylation of MPK4 within and outside of the conserved TEY activation loop was observed. To elucidate how MPK4 functions during the defense response, we used immunoprecipitation coupled with mass spectrometry (IP-MS) to identify MPK4 interacting proteins in the absence and presence of flg22. Quantitative proteomic analysis revealed a shift in MPK4-associated protein network, providing insight into the molecular functions of MPK4 at a systems level.

Mitogen-activated protein kinase 4 regulated metabolic networks

Project description:Mitogen-activated protein kinase 4 (MPK4) was first identified as a negative regulator of systemic acquired resistance (SAR). It is also an important kinase that gets involved in other plant biological processes in plants, including cytokinesis, reproduction and photosynthesis. Arabidopsis thaliana mpk4 mutant is a dwarf and sterile. Previous ‘omics’ studies including genomics, transcriptomics and proteomics have revealed new functions of MPK4 in different biological processes. However, due to challenges in metabolomics, no study has focused on metabolomic profiles of the mpk4 mutant and what metabolites and metabolic pathways are potentially regulated by MPK4 are not known. Metabolites are crucial components of plants, which plays an and they play important roles in plant signaling, defense, and growth and development. Here we used targeted and untargeted metabolomics to profile metabolites in wild type (WT) and the mpk4 mutant where we found that in addition to jasmonic acid (JA) and salicylic acid (SA) pathways, MPK4 got involved in polyamine synthesis and photosynthesis. In addition, we also conducted label-free proteomics of the two genotypes. Integration of metabolomics and proteomics data allowed insight into the metabolomic networks that are potentially regulated by MPK4.

Characterization of the starvation response in the Arabidopsis dcl1-9 mutant

Project description:The SnRK1 protein kinase, the plant ortholog of mammalian AMPK and yeast Snf1, is activated by the energy depletion caused by adverse environmental conditions. Upon activation, SnRK1 triggers extensive transcriptional changes to restore homeostasis and promote stress tolerance and survival partly through the inhibition of anabolism and the activation of catabolism. Despite the identification of a few bZIP transcription factors as downstream effectors, the mechanisms underlying gene regulation, and in particular gene repression by SnRK1, remain mostly unknown. microRNAs (miRNAs) are 20-24nt RNAs that regulate gene expression post-transcriptionally by driving the cleavage and/or translation attenuation of complementary mRNA targets. In addition to the well-established role of miRNAs as regulators of plant development, mounting evidence implicates miRNAs in the response to environmental stress. Given the involvement of miRNAs in stress responses and the fact that some of the SnRK1-regulated genes are miRNA targets, we postulated that miRNAs drive part of the transcriptional reprogramming triggered by SnRK1 activation. To test this we have performed comparative analyses of the transcriptional response to energy deprivation between WT and dcl1-9, a mutant deficient in miRNA biogenesis. To assess the impact of miRNA deficiency on the starvation response we performed transcriptomics analyses of WT and dcl1-9 plants by subjecting leaves to 6h of light (control) or darkness (starvation)

Protein production by Aspergillus oryzae

Project description:The filamentous fungus Aspergillus oryzae is an important microbial cell factory for industrial production of useful enzymes, such as α-amylase. In order to optimize the industrial enzyme production process, there is a need to understand fundamental processes underlying protein production, here under how protein production links to metabolism through global regulatory structures. In this study, two α-amylase-producing strains of A. oryzae, a wild type strain and a transformant strain containing additional copies of the α-amylase gene, were characterized at a systematic level. Based on integrated analysis of ome-data together with genome-scale metabolic network and flux calculation, we identified key genes, key enzymes, key proteins, and key metabolites involved in the processes of protein synthesis and secretion, nucleotide metabolism, and amino acid metabolism that can be the potential targets for improving industrial protein production. Keywords: Two Aspergillus oryzae strains and two different carbon sources Two carbon sources (glucose, maltose) with three biological replicates for A. oryzae strain A1560 and strain CF1.1

Transcription profiling of human Burkitts lymphoma cells (L3055) treated with low and high concentrations of CD154

Project description:Activated B cells reacting to small amounts of CD40 ligand (CD154) maintain homeostasis by suppressing default apoptosis. Additional outcomes, particularly differentiation, demand higher CD40 occupancy. Here we compared changes in the transcriptome of pleiotropically competent, early-passage L3055 Burkitts lymphoma cells confronted with low (picomolar) and high (nanomolar) concentrations of CD154 to gain insight into how a single receptor sets these distinct phenotypes.
