Mass spectrometry based quantitative proteome analyses for the import mutants ppi2 and tic56-1 as well as for spectinomycin treated Arabidopsis thalian plants

ABSTRACT: We acquired quantitative proteomics data from eight week old ppi2 and tic56-1 mutants as well as from wild type treated with 60 µg/ml spectinomycin and related them to their respective wildtype reference. Protein identification and quantification was performed by data-independent MSE acquisition on a Synapt G2S mass spectrometer (Waters). Quantification was based on the Hi3 method (Silva et al., 2006). Silva, J.C., Gorenstein, M.V., Li, G.Z., Vissers, J.P., and Geromanos, S.J. (2006).

Importance of Translocon Subunit Tic56 for rRNA Processing and Chloroplast Ribosome Assembly.

Köhler Daniel D Helm Stefan S Agne Birgit B Baginsky Sacha S

Plant physiology 20161012 4

Toc159-containing complexes at the outer chloroplast envelope membrane form stable supercomplexes with a 1-MD translocon at the inner chloroplast envelope membrane of which Tic56 is one essential subunit. While the single mutants tic56-1 and ppi2 (toc159) have an albino phenotype and are able to grow heterotrophically, we find the double mutant to be embryo lethal. Comprehensive quantitative proteome profiling with both single mutants in combination with GeneChip analyses identified a posttransc ...[more]

The Arabidopsis NOT4A E3 ligase promotes PGR3 expression and regulates chloroplast function

Project description:Chloroplast function requires the coordinated action of nuclear- and chloroplast-derived proteins, including several hundred nuclear-encoded pentatricopeptide repeat (PPR) proteins that regulate plastid mRNA metabolism. Despite their large number and importance, regulatory mechanisms controlling PPR expression are poorly understood. Here we show that the Arabidopsis NOT4A ubiquitin-ligase positively regulates PROTON GRADIENT 3 (PGR3), a PPR protein required for translating 30S ribosome subunits and several thylakoid-localised photosynthetic components within chloroplasts.

The small RNA PsrR1 affects oligomerization of photosystem I by post-transcriptional repression of psaL in Synechocystis sp. PCC6803

Project description:Comparison of gene expression of WT Synechocystis cells with cells overexpressing the sRNA PsrR1 in order to detect direct targets of the sRNA PsrR1. We monitored gene expression of an Synechocystis PCC6083 overexpressor strain (psrR1+) (Mitschke et al., 2011) harboring a self-replicating plasmid from which PsrR1 is transcribed under control of the copper responsive PpetJ promoter and a control strain (WT) harboring an empty plasmid 0h and 24 h after copper depletion. For the timepoint (0h) we sampled biological replicates and for timepoint (24h) we sampled biological triplicates.

Systematic Discovery of Deeply conse4rved Plant Protein Complexes, soy

Project description:The associated files are mass spec data from 2 Size exclusion chromatography experiments. The material was a native extract prepared from the green leafy tissue of approximately two-week-old soy sprouts. For size calibration the extract for the second fractionation was spiked with three size markers (Sigma-Aldrich MWGF1000) Thyroglobulin, beta-amylase, and BSA.

The Arabidopsis kinase YODA regulates non-canonical immune responses conferring broad-spectrum disease resistance

Project description:Mitogen-activated protein kinases (MAPK) cascades play essential roles in plants and animals by transducing developmental cues and environmental signals into cellular responses. Among the latter are microbe-associated molecular patterns perceived by plant pattern recognition receptors (PRRs), which trigger immunity. We found that YODA (YDA), a MAPK kinase kinase regulating several Arabidopsis developmental processes, like stomatal and embryo patterning, also modulates immune responses. Resistance to pathogens is compromised in a yda11 hypomorphic allele whereas plants expressing the constitutively active YDA (CA-YDA) protein show broad-spectrum disease resistance to necrotrophic and biotrophic fungi, bacteria and oomycetes. We found that YDA functions downstream ERECTA (ER) Receptor-Like Kinase regulating both immunity and stomatal patterning. ER/YDA-mediated immune responses act in parallel to canonical disease resistance pathways regulated by defensive phytohormones and PRRs, like FLS2 and CERK1, which are required for bacterial and fungal resistance, respectively. CA-YDA plants constitutively express defense-associated genes and exhibit altered cell wall integrity, which contribute to their broad-spectrum disease resistance. CA-YDA plants also show a strong reprogramming of their phosphoproteome, which contains protein targets that do not significantly overlap with described plant MAPKs substrates. Our data suggest that plants might have evolutionarily co-opted the stomata development pathway regulated by ER/YDA to generate a novel immune surveillance system that is distinct from the canonical immune pathways mediated by previously described PRRs and plant defensive hormones.

Systematic Discovery of Deeply Conserved Plant Protein Complexes, Arabidopsis seeds

Project description:The associated files are mass spec data from individual fractions of mixed-bed ion exchange chromatography of native extract made from Arabidopsis thaliana (mutant ttg1-1, Koornneef (1981) Arabid. Inf. Serv. 18,45-51.) seeds. This is a hypomorph of the Transparent Testa Glabra 1 gene and was used instead of wild type because it is mucilage-less, facilitating protein extract preparation.

Transcriptome changes triggered by the loss of function of gene Mppcs in genome-edited Marchantia polymorpha plants

Project description:In the present study, Marchantia polymorpha Mppcs loss of function mutants were generated through CRISPR/cas9 mediated genome-editing. To assess whether the knockout of MpPCS gene affects the transcription of M. polymorpha nuclear genes in unstressed condition, the Mppcs-2 knockout mutant and Cam2 wild-type transcriptomes were compared by RNA-Seq.

Tripartite symbiosis formed by Pisum sativum, rhizobia and mycorrhiza: Implications for the symbionts, the host plant and the pathogenic fungi, part 2

Project description:The lower needs for chemical fertilisers make the Pisum Sativum well suited for sustainable agricultural systems. During the past decades, yield losses were mainly due to pathogenic infestation, with Ascochyta blight as the most severe disease. In this fungal disease complex Didymella pinodes, as the most aggressive pathogen, has been examined intensively. Despite the great number of varieties, no resistance was yet found and several strategies were developed to avoid infestation. In recent years enhanced resistance to pathogens due to previous infestation by symbiotic microorganisms was discovered in several plants. However, only little attention was drawn on the implications of P. Sativum´s symbionts (Rhizobia, Mycorrhiza) on the disease severity as well as the effects of the pathogen on the symbiotic interactions. Hence, here the implications of the pathogenic infestation on the tripartite symbiosis of P. Sativum on a molecular (proteomics, metabolomics) and physiological level, and moreover, the potential of the root symbionts to enhance resistance against Didymella pinodes are investigated.

arabidopsis_thaliana_floral_meristem_atlas

Project description:Transcriptomic changes during early developmental stages of reproductive meristems in Arabidopsis thaliana. Through laser microdissection coupled to RNA sequencing, we provide precise transcriptomic analysis of the inflorescence meristem, floral meristem and of the flower at the beginning of organ differentiation. Transcript abundance quantification and differential expression (DE) analyses were performed using the Bowtie/Tophat/Cufflinks pipeline (BTC) (Trapnell et al., 2012) with the RefSeq Arabidopsis annotation. The BTC pipeline identified 46 genes as differentially expressed between IM and FM, 171 genes differentially expressed between FM and ST3 and 178 genes differentially expressed between IM and ST3. The obtained data turned out to be solid since they are highly consistent with established knowledge but they also allowed the identification of new high profile candidate genes as well as new insights into potential regulatory networks underlying the formation of these reproductive structures. We provide a web interface for easy interrogation of these unique datasets.
