Proteomic analysis of Arabidopsis plda1 mutants

ABSTRACT: PLDa1 is a phospholipid hydrolyzing enzyme playing multiple regulatory roles in stress response in plants. Its signaling activity is mediated via the PLDa1 dependent phosphatidic acid production, by its capacity to bind and modulate the G-protein complex or by interaction with other proteins. Relative quantitative proteomic analysis of two tDNA insertion Arabidopsis plda1 mutants has been performed. Remarkably, PLDa1 deficiency caused differential regulation of many proteins which form protein complexes.

Phospholipase D alpha 1 (PLDα1) is a phospholipid hydrolyzing enzyme playing multiple regulatory roles in stress responses of plants. Its signaling activity is mediated by phosphatidic acid (PA) production, capacity to bind, and modulate G-protein complexes or by interaction with other proteins. This work presents a quantitative proteomic analysis of two T-DNA insertion pldα1 mutants of Arabidopsis thaliana. Remarkably, PLDα1 knockouts caused differential regul ...[more]

Functional characterization of Taf4b in Arabidopsis thaliana

Project description:Expression analysis was performed with two TDNA insertion mutants of taf4b i.e; taf4bprm (TDNA insertion in promoter region) and taf4bint (TDNA insertion in intronic region), Taf4b overexpression lines, taf4bprmcpr5 double mutant lines (Double mutant was generated by crossing taf4bprm with cpr5) and Col-0 in normal condition as well as with taf4bprm mutant and Col-0 infected with fungi AB (Alternaria brassicicola) and bacteria ES4 (Pseudomonas syringae pv.maculicola ES4326 ) in different perspectives. Affymatrix expression analysis was executed to provide mechanistic details of regulation of genes by Taf4b in plants.

HIV-1 integrase variants retarget viral integration and are associated with disease progression in a chronic infection cohort.

Project description:Distinct integration patterns of different retroviruses have puzzled virologists for over 20 years. The viral integrase (IN), as part of the intasome complex, docks onto the target DNA (tDNA) and catalyzes the insertion of the viral genome into the host chromatin. We identified retroviral IN amino acids directly contacting tDNA bases and affecting the local integration site sequence biases. These residues also determine the propensity of the virus to integrate into flexible tDNA sequences. Remarkably, natural polymorphisms INS119G and INR231G retarget viral integration away from gene dense regions, without affecting the interaction with the lentiviral tethering cofactor LEDGF/p75 (PSIP1). Precisely these variants were associated with rapid disease progression in a chronic HIV-1 subtype C infection cohort. These findings link integration site selection to virulence and viral evolution but also to the host immune response and antiretroviral therapy, since HIV-1 IN119 is under selection by HLA alleles and integrase inhibitors.

Transcription profiling of Arabidopsis CYP98A3 knockout mutant

Project description:TDNA insertion mutants in CYP98A3 were produced by K. Feldmann, and studied through transcriptomic analysis against the wild type WS (specific insertion was checked by PCR and segregation analysis). Characterization of knockout mutants for P450s can be very helpful to fully understand the function of the disrupted gene, and is expected to generate information about the molecular basis of mutants phenotype.

HAP5 Triple Mutant vs. Constans Mutant

Project description:Aims: To compare the transcriptional profiles of an AtHAP5 (AtNF-YC, AtCBF-C) triple mutant vs. a Constans mutant. Background Information on Mutants: AtHAP5 triple mutant created by cross between the following SALK TDNA inserts: SALK_034838, SALK_058903, SALK_032163; these correspond to At1G54830, At1G08970, At5G63470, respectively. co-SAIL TDNA insertion SAIL_24_H04 corresponds to AT5G15840. Tissue: Above-ground whole plants grown for 10 days, under 16 hr light 8 hrs dark at constant 22C. Tissue collected 14 hrs after lights on. RT-PCR analysis on test RNA confirmed FT levels reduced in mutants lines compared to wild-type. 9 samples were used in this experiment.

What is the transcriptomic contrast between a TDNA-mutant and its respective wild-type from young Arabidopsis rosette?

Project description:ra15-07_burxcol_465 - burxcol-465 - What is the transcriptomic contrast between a TDNA-mutant and its respective wild-type from young rosette grown in precisely-controlled conditions on our phenotyping robot (Phenoscope)? - The candidate gene (AT1G36310) was identified through QTL mapping and cloning for rosette leaf growth trait in a Bur x Col RIL set. It corresponds to a medium effect on growth and a major effect on other traits (leaf colour and pigments). We are now exploiting an independent TDNA-insertion line (SALK_135308) in the Col-0 background) to study its effect in a simple genetic context. This is a simple comparison between homozygous T-DNA (2 lines) and their respective WT (2 lines).

Arabidopsis MED8 functions in oxidative stress

Project description:In this work, we describe a TDNA insertion mutant for Mediator complex subunit 8 (MED8) that regulates the oxidative stress responses. Wild-type Col-0 and med8 seedlings were growth under control condition or oxidative stress (induced by methyl viologen treatment) and were subjected to RNA-seq profiling. Total mRNA fractions were isolated and subjected to signle-end deep sequencing (approx.30M reads/sample) to reveal differential expression between genotypes and conditions.

HiRIEF Proteomics of Arabidopsis thaliana Col-0 and CIAF1 mutants

Project description:The assembly of the mitochondrial Complex I requires the expression of nuclear and mitochondrial located genes, co-factor biosynthesis and the assembly of at least 44 subunits. This requires the involvement of assembly factors that interact with subunits of Complex I but are not part of the final holocomplex. A novel plant specific mitochondrial matrix protein encoded by At1g76060, named COMPLEX I ASSEMBLY FACTOR 1 (CIAF1), containing a conserved LYR domain, was shown to be required for Complex I activity. T-DNA insertion mutants of At1g76060 lack the monomeric Complex I and the Supercomplex I+III, displaying the common Complex I growth deficient phenotype. Assembly of Complex I is stalled at 650 and 800 kDa intermediates in mitochondria isolated from these mutants. Evidence points to CIAF1 playing an essential role in the assembly of the peripheral matrix arm Complex I subunits to form the holoenzyme Complex I. We here performed quantitative proteomics by HiRIEF LC-MS with a TMT10plex isobaric tag labeling strategy comparing the control plant Col-0 and several mutant lines, including the mutant with inactivating insertion in At1g76060 (a.k.a. Ciaf1-1, a.k.a. SALK_143656). Among up-regulated proteins were components required for mitochondrial biogenesis, which points to a mitochondrial retrograde signaling pathway being activated and executed in response to the lack of Complex I.
