Full textThe mitochondrial DNA (mtDNA) of flowering plants is characterized by the recombination activities that modulate its structure. These activities are required for the mtDNA maintenance, and drive its rapid structural evolution. The factors that control recombination are therefore essential for plant mtDNA stability. During my PhD, I identified and characterized two DNA helicases that are present in the organelles of Arabidopsisthaliana. One is the homologue of a bacterial helicase involved in transcription-coupled repair. Its role in the plant organelles is still not determined. The other one, the RECG1 helicase, has roles in recombination dependent repair, the surveillance of ectopic recombination involving short repeated sequences, and also the segregation of the mtDNA. We have found that in the absence of RECG1 there is loss of recombination control resulting in the occurrence of alternative versions of the mtDNA generated by recombination. The analysis oftheir segregation, induced by RECG1, allowed us to build a model to how new stable mtDNA configurations are generated by the stoichiometric shift of mtDNA sub-genomes. This work allowed us to better understand the recombination and segregation mechanisms that modulate the Arabidopsis mtDNA

Full textFor long, the plant mitochondrial genome (mtDNA) was not amenable to manipulation, until recent advancements in genome engineering using Transcription Activator-Like Effector Nucleases (TALEN). In this work I used TALENs specifically targeted to mitochondria (mitoTALENs) to study plant mtDNA repair and segregation. MitoTALEN constructs were transformed into the background of 10 different Arabidopsis thaliana mutant lines, deficient in various factors involved in plant mitochondrial repair by homologous recombination. The resulting lines were analysed by Illumina sequencing and qPCR approaches. In wild type plants, the mtDNA double-strand-break (DSB) induced by MitoTALENs was repaired by homologous recombination, resulting in the replacement of the region containing the DSB by a distal unaffected sequence of the mtDNA, flanked by the same set of repeated sequences. In mutants deficient in repair factors, repair could shift to alternative pathways, such as Single-Strand Annealing (SSA) and Microhomology-mediated recombination (MHMR). Furthermore, in some mutants, the data revealed no evidence of DSB repair, but rather suggested that plants deficient in key repair factors could survive by reconstituting an alternative viable mitochondrial genome, from pre-existing autonomously replicating sub-genomes

Full textMitochondria are organelles that possess their own genome, the mitochondrial DNA (mtDNA). Repair of oxidative damages, defective replication, or various exogenous sources, such as chemotherapeutic agents or ionizing radiations, can generate double-strand breaks (DSBs) in mtDNA. MtDNA encodes for essential proteins involved in ATP production and maintenance of integrity of this genome is thus of crucial importance. Mutations in mtDNA are indeed found in numerous pathologies such as mitochondrial myopathies, neurodegenerative disorders or cancers. However, the mechanisms involved in mtDNA maintenance after DSBs remain unknown.To elucidate this question, we have generated mtDNA DSBs using a human inducible cell system expressing the restriction enzyme PstI targeted to mitochondria. Using this system, we could not find any support for DSBs repair of mtDNA. Instead we observed a loss of the damaged mtDNA molecules and a severe decrease in mtDNA content, followed by reamplification of intact mtDNA molecules. We have demonstrated that none of the known mitochondrial nucleases are involved in mtDNA degradation and that DNA loss is not due to autophagy, mitophagy or apoptosis but to a selective mechanism. Our study suggests that a still uncharacterized pathway for the targeted degradation of damaged mtDNA in a mitophagy/autophagy-independent manner is present in mitochondria, and might provide the main mechanism used by the cells to deal with DSBs. Global approaches are ongoing to identify proteins involved in degradation of damaged mtDNA following DSBs, mainly an RNAi screen targeting 80 nucleases. In parallel we are interested in a family of phosphohydrolases named Nudix and their putative protective role in sanitizing the nucleotides pool in mitochondria

Full textThe mitochondrial DNA of plants is dynamic and its expression is complex. Using a strategy based on the natural import of nuclear-encoded transfer RNAs from the cytosol, we targeted to mitochondria in Arabidopsis thaliana the orf77 RNA characteristic for S-CMS in maize and we analyzed the effects on the transcriptome. The results showed that the mitochondrial transcriptome is tighly regulated during plant development and is strongly buffered at early stages. Mitochondrial targeting of orf77 also triggered a cross-talk with the nucleus. On the other hand, DNA replication and repair in plant mitochondria involve active recombination controled by nuclear-encoded factors. We identified a new member of this set of factors, the 5'-3' exonuclease potentially responsible for the resection of DNA ends in recombination-mediated repair of double-strand breaks. As a whole, the results open prospects for generating mitochondrial genetic diversity and creating CMS lines with agronomical interest

Full textMitochondria possess their own DNA (mtDNA) and are a major source for Reactive Oxygen Species (ROS) production. Due to its close proximity to the ROS source the mtDNA is a likely to be oxidized. 8-oxo-guanine (8oxoG) and uracile are the most studied oxidative lesion and are repaired by the Base Excision Repair (BER) pathway. This DNA repair pathway is also the only one found with absolute certainty in mitochondria. As the question of DNA repair in plant’s organelles remains open our laboratory has initiated a study whose aim was to show whether mitochondria and chloroplast are able to repair DNA or not. In a first set of in vitro experiments we have shown that plant organelle do actually harbor DNA glycosylase and AP endonuclease activities, and that some part of each activities is somehow present in a membrane associated fashion. The second set of in organello experiments has enable us to show that a DNA carrying uracile can be imported and fully repaired in plant mitochondria. So, these organelles do actually have also DNA repair synthesis and ligase activity. The presence of a complete BER pathway in plant mitochondria is thus undoubtful, but the question of its association with the membrane remains open and the protein involved in this pathway should still be identified

Full textERCC1-XPF (Excision Repair Cross Complementing gene 1/Xeroderma Pigmentosum group F) is a heterodimeric endonuclease involved in many DNA repair systems. Phenotypes of ERCC1 deficiency in diverse organisms suggest that this protein may have an additional role in the regulation of cell cycle progression. To evaluate this hypothesis in human tumoral and non-tumoral cell lines, we knocked-down ERCC1 by RNA interference (ERCC1KD). Our results have shown that ERCC1KD cells become multinucleated, not only in tumoral cells but also in non-tumoral cells and regardless of tissue type. These multinucleated cells accumulate nuclei through abnormal mitoses ending by a defective cytokinesis. In addition, when mitotic abnormalities are too drastic, ERCC1KD cells die in mitosis, and this is highly reminiscent of mitotic catastrophe. In an original way, cells knocked-down for XPF do not share this phenotype of multinucleation, suggesting for the first time that ERCC1 could bear a new role, independently of its known DNA repair activity. Furthermore, we have provided evidence suggesting that this new role of ERCC1 could potentially involve the oxidant/antioxidant balance and could be linked to a mitochondrial function. This ERCC1 new role may be crucial for development, growth, proliferation and cell survival. Finally, it may be conceivable that ERCC1 might become a new promising therapeutic target for cancer treatment
