Complexome profiling of mitochondrial complexes isolated from seedlings or mature leaves

ABSTRACT: Assembly of the plant OXPHOS complexes was studied using complexome profiling. mitochondria were extracted from seedlings or mature leaves of the reference organism Arabidopsis thaliana. In seedlings, a fast-growing tissue, mitochondria biogenesis is very active whereas in mature leaves, little biogenesis is occurring. Comparison of both datasets allow the identification of assembly intermediates that are accumulating in seedlings but not in leaves.

The assembly pathway of complex I in Arabidopsis thaliana.

All present-day mitochondria originate from a single endosymbiotic event that gave rise to the last eukaryotic common ancestor more than a billion years ago. However, to date, many aspects of mitochondrial evolution have remained unresolved. Comparative genomics and proteomics have revealed a complex evolutionary origin for many mitochondrial components. To understand the evolution of the respiratory chain, we have examined both the components and the mechanisms of the assembly pathway of comple ...[more]

Transcriptome-wide analysis of gene expression using detached first-pair rosette leaves before culture (time 0) and 1 day after culture (DAC) from 9-day-old, 12-day-old and 15-day-old Col-0 seedlings

Project description:To analyze the molecular mechanism behind the relationship between Arabidopsis leaf maturation and de novo root regeneration, we carried out an RNA-seq analysis using detached first-pair rosette leaves before culturing (time 0) and 1 d after culturing (DAC) from 9-, 12- and 15-d-old Col-0 seedlings. We first analyzed gene expression levels in the leaves before detachment (at time 0) from the three developmental states. Changes in gene expression could be grouped into six clusters. Many genes were upregulated or downregulated during leaf maturation. Next, we analyzed gene expression levels in the leaf explants from 9- and 15-d-old seedlings at 1 DAC compared with gene expression levels at time 0. By comparing up- or downregulated genes (1 DAC vs time 0) between leaves from 9- and 15-d-old seedlings, we found that many of the genes were particularly up- or downregulated only in immature leaves or only in mature leaves after 1 d of culturing.

Defective mitochondrial translation due to loss of COX14 function triggers ROS-induced inflammation in liver

Project description:Mitochondrial oxidative phosphorylation (OXPHOS) fuels cellular ATP demands. OXPHOS defects lead to severe human disorders with unexplained tissue specific pathologies. Mitochondrial gene expression is essential for OXPHOS biogenesis since core subunits of the complexes are mitochondrial-encoded. COX14 is required for translation of COX1, the central mitochondrial-encoded subunit of complex IV. Here we generated a COX14 mouse mutant corresponding to a patient with complex IV deficiency. COX14M19I mice display broad tissue-specific pathologies. A hallmark phenotype is severe liver inflammation linked to release of mitochondrial RNA into the cytosol sensed by RIG-1 pathway. We find that mitochondrial RNA release is triggered by increased reactive oxygen species production in the absence of complex IV. Additionally, we also generated a COA3Y72C mouse, affected in COX1 biogenesis, which displays a similar yet milder inflammatory phenotype. Our study provides mechanistic insight into how defective mitochondrial gene expression causes tissue-specific inflammation.

Transcriptome maps of mRNP biogenesis factors define pre-mRNA recognition

Project description:Biogenesis of eukaryotic messenger ribonucleoprotein complexes (mRNPs) involves the synthesis, splicing, and 3M-bM-^@M-^Y-processing of pre-mRNA, and the assembly of mature mRNPs for nuclear export. We mapped 23 mRNP biogenesis factors onto the newly synthesized yeast transcriptome, providing ~10^5-10^6 high-confidence RNA interaction sites per factor.

Transcription factor ATAF1 integrates carbon starvation responses with trehalose metabolism

Project description:Global transcriptome patterns were obtained from ATAF1-IOE seedlings at 1 h, 2 h and 5 h after estradiol induction or mock treatment, and from mature ATAF1-IOE leaves at 5 h after estradiol induction or mock treatment. To identify genes rapidly responding to elevated ATAF1 expression estradiol induction experiments were performed on ATAF1-IOE seedlings after 1 h, 2 h and 5 h of ATAF1 induction. In addition, expression profiles were obtained from mature leaves after 5 h of ATAF1 induction.
