Multi-Protease Investigation of Arabidopsis Thaliana Cell Culture Mitochondria

ABSTRACT: The aim of this project is to deeply map the proteome of mitochondria from the model plant Arabidopsis thaliana. For this purpose, mitochondria were isolated from Arabidopsis cell cultures, their proteins extracted and processed using SP3 digestion. To achieve high sequence coverage, the proteins were digested with a total of six different proteases and measured using sensitive timsTOF Pro hardware and TIMS fractionation.

Deep Proteomics reveals incorporation of unedited proteins into mitochondrial protein complexes in Arabidopsis.

Rugen Nils N Senkler Michael M Braun Hans-Peter HP

Plant physiology 20231207

The mitochondrial proteome consists of numerous types of proteins which either are encoded and synthesized in the mitochondria, or encoded in the cell nucleus, synthesized in the cytoplasm and imported into the mitochondria. Their synthesis in the mitochondria, but not in the nucleus, relies on the editing of the primary transcripts of their genes at defined sites. Here, we present an in-depth investigation of the mitochondrial proteome of Arabidopsis (Arabidopsis thaliana) and a public online p ...[more]

HPLC-TIMS-TOF-MS of purified mitochondrial I+III2 supercomplex from Arabidopsis thaliana

Project description:Mitochondrial I+III2 supercomplex was purified from Arabidopsis thaliana cells using differential centrifugation including Percoll step gradients and continuous sucrose gradients. Supercomplex fractions were digested with trypsin using the SP3 approach. Peptides were further purified with SepPak cartridges and measured by HPLC-ESI-TIMS-TOF-MS. Database search was performed with MaxQuant (Version 2.0.3.0.) Over 1,300 proteins were identified using this highly sensitive approach, including all known subunits of the I+III2 supercomplex. This MS analysis is part of a publication on the structure of the I+III2 supercomplex from Arabidopsis by Klusch et al., 2022.

Rapid single-step affinity purification of HA-tagged mitochondria from Arabidopsis thaliana

Project description:Photosynthesis in plant cells would not be possible without the supportive role of mitochondria. However, isolating mitochondria for physiological and biochemical analyses from plant cells is a lengthy and tedious process. Established isolation protocols require multiple centrifugation steps and substantial amounts of starting material. To overcome these limitations, we tagged mitochondria in plant cells with a triple haemagglutinin-tag for rapid purification by a single affinity purification step. This protocol yields highly purified mitochondria from 1 g of Arabidopsis seedlings that are suitable for enzyme activity measurements and delivers sufficient amounts of mitochondrial proteins for deep proteomic profiling. We demonstrate that the method can be applied to proteomic analysis of an Arabidopsis mutant deficient in the mitochondrial glutamate transporter À bout de souffle (BOU) and we identify 27 differentially expressed proteins in the bou mutant. Our work also sets the stage for the development of advanced isolation protocols for mitochondria from distinct cell types.

Protein Interaction Patterns in Arabidopsis thaliana Leaf Mitochondria Change in Response to Illumination

Project description:Light is the most important cue for plant metabolism since its presence enables photosynthesis. Mitochondria respond to light conditions by adjusting flow through the citric acid cycle and the respiratory chain to support photosynthesis in the light and provide the cell with ATP in the light and in the dark. The data presented here serve in identifying changes in protein:protein interactions (PPIs) of Arabidopsis thaliana leaf mitochondria in response to illumination and pave the way towards an understanding how PPIs affect and regulate mitochondrial metabolism.

Analysis of the translational landscape of Arabidopsis mitochondria

Project description:Messenger RNA translation is a complex process that is still poorly understood in eukaryotic organelles like mitochondria. Growing evidence indicate though that mitochondrial translation differs from its bacterial counterpart in many key aspects. In this analysis, we used the ribosome profiling technology to generate a genome-wide snapshot view of mitochondrial translation in Arabidopsis. We show that, unlike in humans, most Arabidopsis mitochondrial ribosomes footprints measure 27 and 28 bases. We also reveal that respiratory subunits encoding mRNAs show much higher ribosome association than other mitochondrial mRNAs, implying that they are translated to higher levels. Homogenous ribosome densities were generally detected within each respiratory complex except for complex V where higher ribosome coverage corroborate with higher needs in specific subunits. In complex I respiratory mutants, a slight reorganization of mitochondrial mRNAs ribosome association was detected involving an increase in ribosome densities on certain ribosomal protein encoding transcripts and a reduction in the translation of a few complex V mRNAs. Altogether, our observations reveal that plant mitochondrial translation is a dynamic process and that translational control is important for gene expression in plant mitochondria. This study paves the way for future advances in the understanding of translation in higher plant mitochondria.

Mitochondria-originating novel coding gene sORF2146 controls flowering

Project description:It has been reported that a number of small coding genes (30–100 amino acids) tend to be lineage-specifically emerged in evolution but such de-novo genes tend to be missed in genomes. Plant mitochondrial genomes might be fostering sources of de-novo genes because of a high rearrangement rate. However, the functional role of de-novo genes derived from mitochondria is unclear. Here, in the best model species of plants (Arabidopsis thaliana), we showed that Arabidopsis-specifically emerged de-novo genes derived from mitochondrial genome contributed to phenotypic variation in a species. We previously identified 49 candidates of small coding genes inducing abnormal morphological changes on overexpression in the nuclear genome. Among them, we focused on a candidate (sORF2146) potentially encoding 66 amino acids in large-scale intergenic genomic transferring region from mitochondrial genome. Comparative genome analysis showed that sORF2146 had been appeared in Arabidopsis lineage. Mitochondrial sORF2146 is fixed among A. thaliana ecotypes but nucleus sORF2146 is not fixed in A. thaliana ecotypes. After showing evidence that nucleus sORF2146 was transcribed and translated as a coding gene, we performed transcriptome analysis in transgenic plant overexpressing sORF2146. Genes associated with flowering transition are highly regulated in the transgenic plant. We then examined phenotypic effects of overexpression and knockdown transgenic plant. Overexpression and knockdown transgenic plant induce late and early flowering, respectively. Taken together, we conclude that a nucleus de-novo gene derived from mitochondria contributes to the variation of floral timing in Arabidopsis population.

Human mitochondria hub of small RNAs: Analysis by deep Sequencing

Project description:We report here that human mitochondria contain small RNA including microRNA, piRNA, tRNA, rRNA, and RNA repeats. Mitochondria from human cells were purified and RNA isolated. Small RNAs were purified, library generated and analyzed by Illumina Hiseq 2000 system. The sequencing generated 19.5 and 17.7 million reads from HEK-293 and HeLa respectively. 91% and 97% sequences of HEK293 and HeLa respectively were annotated to various classes of small RNA. The total percentage of 4.21 and 2.58 sequences from HEK293 and HeLa respectively was found to be of miRNA. Further, we found only 1.2 % sequences from both the libraries aligned to mitochondrial genome. These results suggest that there is efficient transport of nuclear encoded small RNA to mitochondria. The small RNA in mitochondria may regulate critical cellular processes. Analyzing the smallRNA in human mitochondria from two human cell lines (HEK-293 and HeLa).

CircRNAs in Arabidopsis thaliana across the lifespan

Project description:To explore the overall circRNAs involved in growth and development of Arabidopsis thaliana across the lifespan, we deeply sequenced samples of whole plants from different developmental stages (cotyledons emergence, rosette leavesï¹¥1 mm, rosette growth complete, first flower open, flourishing florescence, first silique shattered, senescence). The total RNA was purified by rRNA-depletion and linear RNA removal with RNAseR, and sequenced by the Illumina HiSeq2500 platform. We obtained 31 Gb raw data and identified 1217 circRNAs with expression quantity. We annotated these circRNAs and predicted their targeted microRNA. The circRNAs involved in growth and development of Arabidopsis thaliana across lifespan were identified and analyzed using the Illumina HiSeq2500 platform.
