Intriguingly, TEs are activated in the sperm companion cell – vegetative cell (VC) – of the flowering plant Arabidopsis thaliana. However, the extent and mechanism of this activation are unknown. Here we show that about 100 heterochromatic TEs are activated in VCs, mostly by DEMETER-catalyzed DNA demethylation. We further demonstrate that DEMETER access to some of these TEs is permitted by the natural depletion of linker histone H1 in VCs. Ectopically expressed H1 suppresses TEs in VCs by reducing DNA demethylation and via a methylation-independent mechanism. We demonstrate that H1 is required for heterochromatin condensation in plant cells and show that H1 overexpression creates heterochromatic foci in the VC progenitor cell. Taken together, our results demonstrate that the natural depletion of H1 during male gametogenesis facilitates DEMETER-directed DNA demethylation, heterochromatin relaxation, and TE activation."}],"article_number":"42530","file":[{"file_size":2493837,"creator":"alisjak","file_name":"2019_elife_He.pdf","access_level":"open_access","date_updated":"2023-02-07T09:42:46Z","checksum":"ea6b89c20d59e5eb3646916fe5d568ad","relation":"main_file","file_id":"12525","content_type":"application/pdf","success":1,"date_created":"2023-02-07T09:42:46Z"}],"article_processing_charge":"No","volume":8,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"file_date_updated":"2023-02-07T09:42:46Z","main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6594752/","open_access":"1"}],"oa":1,"publication_status":"published","has_accepted_license":"1","year":"2019","oa_version":"Published Version","article_type":"original","publication_identifier":{"issn":["2050-084X"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-05-08T10:54:12Z","scopus_import":"1","external_id":{"unknown":["31135340"]}},{"month":"11","extern":"1","date_created":"2021-11-29T08:51:38Z","publication":"eLife","quality_controlled":"1","status":"public","intvolume":"         6","publisher":"eLife Sciences Publications","day":"09","type":"journal_article","author":[{"last_name":"Helle","full_name":"Helle, Sebastian Carsten Johannes","first_name":"Sebastian Carsten Johannes"},{"last_name":"Feng","full_name":"Feng, Qian","first_name":"Qian"},{"last_name":"Aebersold","full_name":"Aebersold, Mathias J","first_name":"Mathias J"},{"last_name":"Hirt","full_name":"Hirt, Luca","first_name":"Luca"},{"first_name":"Raphael R","full_name":"Grüter, Raphael R","last_name":"Grüter"},{"first_name":"Afshin","full_name":"Vahid, Afshin","last_name":"Vahid"},{"full_name":"Sirianni, Andrea","first_name":"Andrea","last_name":"Sirianni"},{"full_name":"Mostowy, Serge","first_name":"Serge","last_name":"Mostowy"},{"full_name":"Snedeker, Jess G","first_name":"Jess G","last_name":"Snedeker"},{"orcid":"0000-0002-7854-2139","id":"bf63d406-f056-11eb-b41d-f263a6566d8b","last_name":"Šarić","first_name":"Anđela","full_name":"Šarić, Anđela"},{"last_name":"Idema","full_name":"Idema, Timon","first_name":"Timon"},{"full_name":"Zambelli, Tomaso","first_name":"Tomaso","last_name":"Zambelli"},{"full_name":"Kornmann, Benoît","first_name":"Benoît","last_name":"Kornmann"}],"citation":{"mla":"Helle, Sebastian Carsten Johannes, et al. “Mechanical Force Induces Mitochondrial Fission.” <i>ELife</i>, vol. 6, e30292, eLife Sciences Publications, 2017, doi:<a href=\"https://doi.org/10.7554/elife.30292\">10.7554/elife.30292</a>.","ista":"Helle SCJ, Feng Q, Aebersold MJ, Hirt L, Grüter RR, Vahid A, Sirianni A, Mostowy S, Snedeker JG, Šarić A, Idema T, Zambelli T, Kornmann B. 2017.

Intriguingly, organelles avoid clashing and entangling with each other in such limited space. Mitochondria form extensive networks constantly remodeled by fission and fusion. Here, we show that mitochondrial fission is triggered by mechanical forces. Mechano-stimulation of mitochondria – via encounter with motile intracellular pathogens, via external pressure applied by an atomic force microscope, or via cell migration across uneven microsurfaces – results in the recruitment of the mitochondrial fission machinery, and subsequent division. We propose that MFF, owing to affinity for narrow mitochondria, acts as a membrane-bound force sensor to recruit the fission machinery to mechanically strained sites. Thus, mitochondria adapt to the environment by sensing and responding to biomechanical cues. Our findings that mechanical triggers can be coupled to biochemical responses in membrane dynamics may explain how organelles orderly cohabit in the crowded cytoplasm.","lang":"eng"}],"article_processing_charge":"No","file_date_updated":"2021-11-29T09:07:41Z","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","image":"/images/cc_by.png","short":"CC BY (4.0)"},"volume":6,"publication_status":"published","main_file_link":[{"open_access":"1","url":"https://elifesciences.org/articles/30292"}],"oa":1,"article_type":"original","has_accepted_license":"1","year":"2017","oa_version":"Published Version","external_id":{"pmid":["29119945"]},"scopus_import":"1","user_id":"8b945eb4-e2f2-11eb-945a-df72226e66a9","date_updated":"2021-11-29T09:28:14Z","publication_identifier":{"issn":["2050-084X"]}}]
