species other than plants as a joint research within and outside of our field. (2) To challenge stable gene transfer beyond the current limitations of genome editing (targeted truncation and base substitution) as a challenge to freely modify cytoplasmic genomes. In particular, we will transiently introduce DNA sequences encoding genome-editing enzymes (in collaboration with the Numata Group) and apply Gene drive to amplify and stabilize inserted genes to create stable foreign gene insertions in the mitochondrial genome of multicellular organisms, which has not been achieved in the world. In addition, to understand the genetic individuality and heterogeneity of mitochondria that exist in cells, we will (3) establish a single organelle genomics analysis technology and (4) elucidate plant mitochondrial heterogeneity using (3). While providing materials and technologies, including newly developed technologies, both within and outside the field, we aim to (5) simplify the technologies (kits and manuals) and spread the use of cytoplasmic genome modification technologies that can be used by anyone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Publications\u3000<span data-fontsize=\"16px\" style=\"font-size: 16px;\" class=\"vk_inline-font-size\">*correspon<\/span><span data-fontsize=\"16px\" style=\"font-size: 16px;\" class=\"vk_inline-font-size\">d<\/span><span data-fontsize=\"16px\" style=\"font-size: 16px;\" class=\"vk_inline-font-size\">ing author<\/span><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Nakazato I, Okuno M, Zhou C, Itoh T, Tsutsumi N, Takenaka M, Arimura SI* (2022) Targeted base editing in the mitochondrial genome of Arabidopsis thaliana. <strong><em>Proc Natl Acad Sci USA<\/em><\/strong>, 119: e2121177119.<\/li>\n\n\n\n<li>Nakazato I, Okuno M, Yamamoto H, Tamura Y, Itoh T, Shikanai T, Takanashi H, Tsutsumi N, Arimura SI* (2021).

organisms, using existing technologies. In this study, we will develop and provide composite biotechnologies that enable selective gene transfer to genome-preserving organelles of diverse target organisms by using fused peptides with different functions, methods combining carbon nanotubes and peptides, and the nanocapsule MITO-Porter. Numata uses the \u201cpeptide method,\u201d a DNA carrier fused with multiple functional peptides, and Yamada uses MITO-Porter, which has been successfully used for mitochondrial delivery of drugs in mammals, to introduce nucleic acids such as DNA into specific organelles within cells. Numata et al. have succeeded for the first time in the world in selectively introducing genes into plant mitochondria by utilizing a fusion peptide consisting of a yeast-derived mitochondrial transfer sequence and a polycation in addition to the cell-permeable peptide CPP. In this research, 1) introduction of the protein into organelles, and 2) development of technology to select modified organelles and cells will be carried out. By delivering the enzymes and coding sequences to the organelle in combination with the genome editing technology of the Arimura group, target-specific insertion of the introduced gene and disappearance of the wild-type genome will be attempted. In addition, we will provide delivery materials to various target organisms in this research area and consult with them about the modification, and establish a standard technology for cytoplasmic genome gene transfer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Publications\u3000<span data-fontsize=\"16px\" style=\"font-size: 16px;\" class=\"vk_inline-font-size\">*corresponding

is regulated in response to organ, developmental, and environmental conditions. The regulatory mechanisms are far more complex than originally thought, and many nuclear-encoded proteins have been identified as regulators of transcription, RNA cleavage, RNA editing, splicing, translation, and RNA degradation. However, the integrated regulatory mechanisms by which they work in tandem remain largely unexplored. In this study, we aim to understand the dynamic regulatory mechanism of organelle gene expression in which multiple molecules work in tandem. To this end, it is necessary to elucidate the relationship between each regulatory factor and genomic DNA and RNA. In collaboration with the Arimura and Yamori groups, we will screen for gene regulatory mutants from random base substitution mutants in the cytoplasmic genome to elucidate the relationship between DNA and RNA sequences and the regulation of gene expression. (2) In collaboration with the Arimura group, introduce mutations near the transcription start site of organelle genes to conduct detailed promoter analysis, which has been technically difficult. (3) We will also convert each C-to-U RNA editing site to T at the DNA stage and analyze its effects in detail to clarify the biological significance of RNA editing as a regulatory mechanism of gene expression. (4) Information synchronization among mitochondria is essential for the regulatory expression of multiple mitochondrial genomic genes. In collaboration with the Arimura, Ishihara, and Nishimura groups, we will analyze the effects of mitochondrial fusion\/division and abnormal formation\/distribution of nucleoid bodies on the regulation of mitochondrial genomic gene expression. Based on the above analysis, we will contribute to this field by aiming to understand the regulatory mechanism of gene expression, which is one of the important pipes connecting the cytoplasmic genome and the life phenomena it plays a role in.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Publications\u3000<span data-fontsize=\"16px\" style=\"font-size: 16px;\"

\u201cmaternal inheritance\u201d and \u201cheteroplasmy\u201d (the ability to exist in a mixed state of intracellular mtDNA). Although these characteristics are fundamental concepts for understanding mitochondrial diseases for which no treatment has been established, their molecular basis and physiological significance are still unresolved issues in mitochondrial genome research. Using a variety of model systems (C. elegans, mouse, mammalian cultured cells, yeast), this research group aims to elucidate the following issues, starting from mitophagy, a mitochondrial quality control mechanism. (1) Elucidation of the molecular mechanism and physiological significance of maternal inheritance, focusing on paternal mitochondria-specific mitophagy, (2) Elucidation of the mechanism that generates differences between sperm and egg mitochondria during germ cell differentiation, (3) Elucidation of the mechanism that maintains heteroplasmy and analysis of its effect on mitochondrial function, (4) Understanding the mechanism of mitochondrial genome quality control by mitophagy and its application to mitochondrial disease model organisms. To accomplish these tasks, we will conduct mitochondrial genome editing in individual animals (nematode worms and mice) using the technology developed by the A01 group, construct an experimental system that can easily distinguish between male and female mitochondrial genomes, and construct mitochondrial disease model organisms to promote research. We will also contribute to the further development of cytoplasmic genome regulation methods by providing feedback to Group A01 on the findings of these mitochondrial genome-specific behaviors and inheritance patterns.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Publications\u3000<span data-fontsize=\"16px\" style=\"font-size: 16px;\" class=\"vk_inline-font-size\">*corresponding author<\/span><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Sato M*, Sato K, Tomura K, Kosako H, Sato K* (2018) The autophagy receptor ALLO-1 and the IKKE-1 kinase control clearance of paternal mitochondria in Caenorhabditis elegans. <strong><em>Nat Cell Biol<\/em><\/strong>, 20: 81\u201391.<\/li>\n\n\n\n<li>Saegusa K, Sato M*, Morooka N, Hara T, Sato K* (2018) SFT-4\/Surf4 control ER export of soluble cargo proteins and participate in ER exit site organization. <strong><em>J Cell Biol<\/em><\/strong>, 217: 2073\u20132085.<\/li>\n\n\n\n<li>Sakaguchi A, Sato M (co-first author), Sato K, Gengyo-Ando K, Yorimitsu T, Nakai J, Hara T, Sato K, Sato K* (2015) REI-1 is a guanine nucleotide exchange factor regulating RAB-11 localization and function in <em>C. elegans<\/em> embryos. <strong><em>Dev Cell<\/em><\/strong>, 35: 211\u2013221.<\/li>\n\n\n\n<li>Sato M*, Konuma R, Sato K, Tomura K, Sato K* (2015) Fertilization-induced K63-linked ubiquitylation mediates clearance of maternal membrane proteins. <strong><em>Development<\/em><\/strong>, 141: 1324\u20131331.<\/li>\n\n\n\n<li>Sato M, Sato K* (2011) Degradation of paternal mitochondria by fertilization-triggered autophagy in <em>C. elegans<\/em> embryos. <strong><em>Science<\/em><\/strong>, 334: 1141\u20131144.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n\n\n\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"b01-3\"><strong><strong><strong><strong><strong>B01-3\uff1aCytoplasmic genome\/chloroplast nucleoid dynamics, repair, and maternal inheritance controlled by ChloroTALEN<\/strong><\/strong><\/strong><\/strong><\/strong><\/h3>\n\n\n\n<div class=\"wp-block-columns vk_block-margin-md--margin-bottom is-layout-flex wp-container-core-columns-is-layout-7387b849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:180px\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"222\" height=\"297\" src=\"https:\/\/www.agr.kyushu-u.ac.jp\/cytoplasmicgenomeregulation\/wpsite\/wp-content\/uploads\/2024\/08\/photo-Nishimura_1.jpg\" alt=\"\" class=\"wp-image-713\"\/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-vk-blocks-spacer vk_spacer vk_spacer-type-margin-top\"><div class=\"vk_block-margin-sm--margin-top\"><\/div><\/div>\n\n\n\n<h4 class=\"wp-block-heading is-style-vk-heading-plain\">PI : Yoshiki NISHIMURA<\/h4>\n\n\n\n<p class=\"vk_custom_css_6 wp-block-paragraph\">Waseda University<br><mark style=\"background-color:#0073b6\" class=\"has-inline-color has-white-color\">Lab HP<\/mark>\u3000<a aria-label=\" (opens in a new tab)\" class=\"ek-link\" href=\"https:\/\/sites.google.com\/view\/shikanailab\/research\/nishimura-group\/english-ver-nishimura-group\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/sites.google.com\/view\/shikanailab\/research\/nishimura-group\/english-ver-nishimura-group<\/a><br><mark style=\"background-color:#0073b6\" class=\"has-inline-color has-white-color\">Researchmap<\/mark>\u3000<a aria-label=\" (opens in a new tab)\" class=\"ek-link\" href=\"https:\/\/researchmap.jp\/7000008742\/?lang=en\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/researchmap.jp\/7000008742\/?lang=en<\/a><br><mark style=\"background-color:#0073b6\" class=\"has-inline-color has-white-color\">ORCID<\/mark>\u3000<a aria-label=\" (opens in a new tab)\" class=\"ek-link\" href=\"https:\/\/orcid.org\/0000-0001-8686-9206\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/orcid.org\/0000-0001-8686-9206<\/a><\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-vk-blocks-accordion vk_accordion group-info\" data-initial-state=\"close\" data-initial-state-mobile=\"\" data-initial-state-tablet=\"\" data-initial-state-desktop=\"\" data-device-specific=\"false\">\n<div class=\"wp-block-vk-blocks-accordion-trigger vk_accordion-trigger\">\n<p class=\"has-text-align-center vk_block-margin-0--margin-bottom wp-block-paragraph\">MORE<\/p>\n<span class=\"vk_accordion-toggle vk_accordion-toggle-close\"><\/span><\/div>\n\n\n\n<div class=\"wp-block-vk-blocks-accordion-target vk_accordion-target\">\n<p class=\"wp-block-paragraph\">Based on chloroplast transitional TALEN (chloroTALEN) and live imaging technology of chloroplast nucleoid, we will investigate the dynamics of chloroplast nucleolus-like bodies during the cytoplasmic genome repair process and the regulatory mechanism of maternal inheritance. (1) Spatiotemporal analysis of chloroplast DNA repair: Chloroplasts, the key component of photosynthesis in plants, have their own DNA (chloroplast DNA) and mechanisms for its replication and gene expression. Chloroplast DNA encodes a set of genes essential for photosynthesis and maintenance of chloroplast function, and its repair and stable inheritance are life-and-death matter for plants. In this study, with the cooperation of the Arimura group, We will develop and induce the expression of a chloroplast-transitional TALEN (chloroTALEN) that introduces a double strand break (DSB) in chloroplast DNA in the model green alga Chlamydomonas, and capture the behavior of chloroplast DNA repair factors in response to this by live imaging. We aim to understand the chloroplast DNA repair system spatiotemporally by such analysis. (2) Development of technology for artificial control of chloroplast maternal inheritance. In the green alga Chlamydomonas, chloroplast DNA is maternally inherited.  We will try to artificially convert and control maternal inheritance to paternal inheritance by expressing chloroTALEN in zygotic females and fragmenting their chloroplast DNA. We will also select mutants in which paternal inheritance is promoted and identify the responsible gene, thereby approaching the molecular mechanism of maternal inheritance. (3) The techniques established in this research and the knowledge obtained will be applied to animals and land plants in cooperation with the Sato, Arimura, and Takenaka groups, aiming to understand cytoplasmic genome repair and maternal inheritance mechanisms in eukaryotes as a whole, thereby contributing to the advancement of this research field.<\/p>\n\n\n\n<h3

and their morphology is regulated by a balance between fusion and fission. However, the details of how mitochondrial internal DNA (mtDNA) is distributed and functionally expressed, and the coordinated regulation of the membrane and genome, are unknown. In this study, we aim to understand the molecular basis for the regulation of mitochondrial genome functions (e.g., respiratory chain complex formation, mtDNA stabilization, and cytoplasmic inheritance) from the perspective of multiple membrane mitochondrial dynamics. In our previous studies, we have found that respiratory chain formation is activated by nucleoid dispersion and that mitochondrial mitogenic factors and mtDNA binding and packaging factors are involved in its regulation. We aim to understand the molecular details by identifying the relevant factors and understanding the molecular mechanisms in detail. Mitochondrial dysfunction contributes not only to mitochondrial diseases but also to aging, diabetes, metabolic diseases, and neurodegenerative diseases. Based on the results of this research, we will construct mitochondrial activation technology in cells and individuals. Based on the molecular findings obtained in this area, we will seek collaboration with clinical research groups in related diseases. The molecular understanding gained from this research will also provide fundamental knowledge for innovations in cytoplasmic genome regulation technologies across species. The project will also contribute to the development of this field by providing broad support for the analysis of mitochondrial function, including respiratory measurements in mammals within the field.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Publications\u3000<span data-fontsize=\"16px\" style=\"font-size: 16px;\" class=\"vk_inline-font-size\">*corresponding author<\/span><\/h3>\n\n\n\n<ol

have mainly focused on plant modification by introducing single or multiple foreign genes targeting the nuclear genome, and have not led to drastic photosynthetic improvement. It is well known that the major rate-limiting factor of photosynthesis is ribulose-1,5-bisphosphate carboxylase\/oxygenase (Rubisco), whose catalytic site rbcL is encoded in the chloroplast genome. However, it has been difficult to improve the catalytic properties of Rubisco because its catalytic site rbcL is encoded in chloroplast genome. Therefore, this project group aims to enhance the photosynthetic ability based on Rubisco modification and elucidate its function by utilizing the \u201cchloroplast genome editing technology\u201d provided by the Arimura Group. Yamori will select photosynthetically competent Arabidopsis mutants from random mutant populations targeting the entire chloroplast genome or the Rubisco catalytic site rbcL gene to elucidate their functions. He also aims to elucidate the catalytic reaction mechanism of Rubisco and design highly catalytically active Rubisco by targeted single nucleotide replacement technology at sites predicted to affect Rubisco catalytic reaction. Fukayama will establish an experimental system in which rbcL is knocked out by chloroplast genome editing and a foreign rbcL with a chloroplast transit peptide is introduced into rice plants. Using this experimental system, we will introduce Rubisco rbcL, a C4 plant with high catalytic speed, and C4-optimized rice rbcL designed using the genetic algorithm GAOptimizer. Analysis of these transformants will be used to search for mutations in the rbcL gene that are effective in improving the Rubisco catalytic properties and to improve the Rubisco enzyme properties. Matsumura will conduct crystal structure analysis and cryo-EM analysis to fully elucidate the catalytic mechanism of the highly efficient and functional Rubisco produced by this project group. YAMORI will support the research on the functional analysis of the photosynthesis\/respiration system using chlorophyll fluorescence and gas exchange measurements, and MATSUMURA will support the structure-function analysis of organelle proteins using \u201cartificial binding proteins\u201d.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Publications\u3000<span data-fontsize=\"16px\"

an organelle within the cell and is passed on to the next generation through maternal inheritance. In order to spread its infection within a host population, <em>Wolbachia<\/em> may manipulate the sex and reproduction of the host, for example, by specifically killing the male (male-killing). It is also known that <em>Wolbachia<\/em>-infected mosquitoes are less likely to transmit dengue virus and malaria. Insect control techniques using <em>Wolbachia<\/em> that apply these unique life phenomena have been devised, and some of them have already been implemented. However, extracellular culture or transplantation of <em>Wolbachia<\/em> is difficult, there is no genetic manipulation technology, and the execution factors and mechanisms of action of <em>Wolbachia<\/em>-specific life phenomena, such as symbiosis mechanisms (maternal inheritance, reduced pathogen vectors) and sexual control mechanisms, remain unresolved except in some cases. Therefore, in this research project, we will elucidate the function of the <em>Wolbachia<\/em> gene, which has not been elucidated so far, through the development of the world's first <em>Wolbachia<\/em> (Wol) TALEN. In the future, we aim to develop insect control technology using <em>Wolbachia<\/em>. To this end, the following three issues will be addressed. (1) We aim to develop WolTALEN by constructing a system to transport TALEN within <em>Wolbachia<\/em> through technical cooperation within this project. Targeting the male-killing factor Oscar (Nat Commun 2022), which we have identified, and using the functional reversion of Masc (Nature 2014), a protein responsible for malefication and gene dosage compensation, as an indicator, we can rapidly evaluate the effects of genome editing. (2) We aim to elucidate the sexual regulation and symbiotic mechanisms of <em>Wolbachia<\/em>, which are becoming organelles, and to develop applications using these mechanisms, as well as to discuss about their commonality and diversity by comparing them with mitochondria and chloroplasts, and contribute to the development of symbiotic organelle studies. We will play a bridging role to intracellular symbiotic bacteria research in this research area and provide WolTALEN within the area (publicly recruited groups) to create diversity and ripple effects in the research.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Publications\u3000<span data-fontsize=\"16px\" style=\"font-size: 16px;\" class=\"vk_inline-font-size\">*corresponding author<\/span><\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Kiuchi T*, Katsuma S (2022) Functional characterization of silkworm PIWI proteins by embryonic RNAi. <strong><em>Methods Mol Biol<\/em><\/strong>, 2360: 19\u201331.<\/li>\n\n\n\n<li>Katsuma S*, Hirota K, Matsuda-Imai N, Fukui T, Muro T, Nishino K, Kosako H, Shoji K, Takanashi H, Fujii T, Arimura S, Kiuchi T (2022) A Wolbachia factor for male killing in lepidopteran insects. <strong><em>Nat Commun<\/em><\/strong>, 13: 6764.<\/li>\n\n\n\n<li>Cortes-Silva N, Ulmer J, Kiuchi T, Hsieh E, Cornilleau G, Ladid I, Dingli F, Loew D, Katsuma S, Drinnenberg IA* (2020) CenH3-independent kinetochore assembly in Lepidoptera requires CCAN, including CENPT. <strong><em>Curr Biol<\/em><\/strong>, 30: 561\u2013572.e10.<\/li>\n\n\n\n<li>Fukui T\u2020, Kawamoto M\u2020, Shoji K\u2020, Kiuchi T\u2020, Sugano S, Shimada T, Suzuki Y, Katsuma S* (2015) The endosymbiotic bacterium Wolbachia selectively kills male hosts by targeting the masculinizing gene. <strong><em>PLoS Pathogens<\/em><\/strong>, 11: e1005048.

genomes, we are challenging to elucidate a novel \u201cmale-killing\u201d system that causes pollen development inhibition in the mitochondrial genome, and to establish a novel F1 breeding system by applying this system. Using precise mutagenesis (mitoTALECD) and gene disruption (mitoTALEN) of the mitochondrial genome, (1) we will clarify the functions of mitochondrial genes whose functions are still unknown (in collaboration with the Arimura Group). (2) We will also identify nuclear genes that may be involved in the regulation of the expression of these genes and elucidate their regulatory mechanisms (in collaboration with the Takenaka Group). Furthermore, by artificially controlling the combination of mitochondrial and nuclear genes identified in (1) and (2), (3) we will create new \u201cmale-killing\u201d plants by genome editing. If these processes reveal the sequence conditions essential to function as a \u201cmale-killer\u201d gene, the \u201cmale-killer\u201d gene can be synthesized artificially. By introducing the synthesized artificial \u201cmale-killing\u201d gene using organelle gene transfer technology (in collaboration with the Numata Group), it will be possible to create \u201cmale-killing\u201d plants that do not rely on genetic resources. Furthermore, by applying the results to other plants, it will be possible to create \u201cmale-killing\u201d plants in plants where \u201cmale-killing\u201d has not yet been obtained, which is a trait with high commercial value, such as efficient F1 seed production. Thus, we show that it is possible to apply this Japanese-originated technology to organelle breeding. Furthermore, we will clarify the biological significance of \u201cmale-killing\u201d in plants by comparing it with the male-killing mechanism in Wolbachia (in collaboration with the Kiuchi group).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Publications\u3000<span data-fontsize=\"16px\" style=\"font-size: 16px;\" class=\"vk_inline-font-size\">*corresponding
