MMS19 is an essential component of the cytoplasmic iron-sulfur (Fe-S) cluster assembly complex in fungi and mammals; the mms19 null mutant alleles are lethal. Our study demonstrates that MMS19/MET18 in Arabidopsis thaliana interacts with the cytoplasmic Fe-S cluster assembly complex but is not an essential component of the complex. We find that MMS19 also interacts with the catalytic subunits of DNA polymerases, which have been demonstrated to be involved in transcriptional gene silencing (TGS), ...[more]

RNA-seq analysis of flg22-induced gene expression changes in wild type, asr3-1 mutant and OX9 overexpression line

Project description:The correlation coefficient (R) for the expression profile of all transcripts between WT and asr3-1, and between WT and OX9 without flg22 treatment is close to linear, suggesting that ASR3 does not affect general gene transcription. Hierarchical clustering analysis flg22-induced genes in any of the three genotypes suggested that the asr3-1 mutant displayed overall enhanced flg22 response whereas OX9 displayed overall reduced responses compared to WT plants. RNA-seq analysis was performed with 10-day-old seedlings of WT, asr3-1 and 35S:ASR3-HA transgenic line OX9 with or without 100 nM flg22 treatment for 30 min. Two independent repeats were performed for RNA-seq analysis. For each repeat, equal amount of RNA from two biological replicates was pooled for RNA-seq library construction. RNA-seq library preparation and sequencing were carried out on an Illumina HiSeq 2500 platform with 100 nt single end reads.

Identification of mRNAs Regulated in Response to Transcriptional Activation of the Arabidopsis Abscisic Acid Insensitive Growth 1 (AIG1) Transcription Factor cDNA

Project description:Liquid grown, seven day old wild type Arabidopsis seedlings and seedlings carrying a cDNA encoding the Abscisic Acid Insensitive Growth (AIG1) gene under the control of an estrogen inducible promoter were treated with estrogen for 0, 60 and 120 minutes at which point seedlings were flash frozen and mRNA was extracted. Wild-type and ESTAIG1 Col samples were treated with estrogen and flash frozen 0, 60 and 120 minutes later. Each sample type has three biological reps, except ESTHAT22.120, which has two. There are therefore 17 total samples. mRNA samples were sequenced by Otogenetics and then analyzed using the Tuxedo suite of applications.

Transcription profiling of Arabidopsis plants overexpressing SlHsfA3

Project description:In order to investigate the possible molecular mechanisms of SlHsfA3 function in plant growth and stress responses, we employed the RNA-seq approach to identify the genes with altered expression levels in the transgenic Arabidopsis overexpressing SlHsfA3. Processing of RNA samples on the Illumina HiSeq 2000 system yielded more than 24 million reads, each 100bp in length, encompassing 2.4Gb of sequence data for each sample which was then mapped to the reference genome. Quantitative analysis of RNA-seq data identified substantial variation in expression profiles among different genotypes, consistent with known functional differences. Transcript abundance obtained from RNA-seq data was indicated as RPKMs and therefore, Up- and down-regulated genes were determined by a greater than 2-fold change of normalized RPKMs in comparison analysis (35S:SlHsfA3 transgenic plants versus Col-0(WT) plants) in both over-expression lines: Q-value < 0.05. The statistical analysis identified a total of 181 differentially expressed genes between OE lines and Col-0(WT) at Q-value < 0.05, among which 114 (63%) were up-regulated and 67 (37%) were down-regulated with fold changes higher than 2. RNA-sequencing was carried out using two independent transgenic lines (35S:SlHsfA3-3 and 35S:SlHsfA3-6). Total RNA was isolated with Trizol reagent (Invitrogen, USA) from the aerial part of the 4-week-old seedlings of 35Spro:SlHsfA3 and Col-0 (WT) plants grown in parallel under unstressed conditions. Materials from 20 plants of each genotype were pooled for RNA isolation.

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.

Cytosolic Hsp60 orchestrates the survival and inflammatory responses of vascular smooth muscle cells in injured aortic vessels by regulating NF-κB-dependent gene expression

Project description:Pro-inflammatory response of VSMCs is triggered by endothelial damage and a causative step for thrombosis and neointimal thickening in the arterial vessels. Therefore, we investigate a role of cytosolic Hsp60 as a novel pro-inflammatory mediator in VSMCs. Hsp60 was detected in the cytosol of VSMCs. The selective depletion of cytosolic Hsp60 in VSMCs reduced the IKK activation, repressed the induction of NF-κB-dependent pro-survival genes (MnSOD and Bfl-1/A1), and enhanced apoptotic death in response to TNF-α. Moreover, a quantitative RNA sequencing revealed that the expression of 75 genes among the 774 TNF-α-inducible genes was significantly reduced by the depletion of cytosolic Hsp60. In particular, the expression of pro-inflammatory cytokines/chemokines, such as CCL2, CCL20, and IL-6, was regulated by the cytosolic Hsp60 in VSMCs. Finally, the depletion of cytosolic Hsp60 markedly inhibited the neointimal thickening in the balloon-injured arterial vessels by inducing apoptotic cell death and inhibiting chemokine production. This study provides the first evidence that cytosolic Hsp60 could be a therapeutic target for preventing inflammation-driven VSMC hyperplasia in the injured vessels.
