What if transposases are already transcription factors in disguise? Our new preprint shows that transcriptional regulatory activity is an intrinsic property of transposases, revealing a direct route for their domestication into transcription factors. www.biorxiv.org/content/10.6...

Leandro Quadrana, lauréat d’une bourse « ERC Consolidator »
Le Conseil européen de la recherche a annoncé le 9 décembre les lauréats des bourses « Consolidator », qui soutiennent chaque année de nombreux projets de scientifiques en milieu de carrière. Leandro Quadrana, directeur de recherche à l’Institute of Plant Sciences Paris-Saclay - IPS2 (CNRS/INRAE/UEVE/UPSaclay, Gif-sur-Yvette), a été retenu pour son projet HosTEome   La recherche de Leandro Quadrana combine des approches de génétique moléculaire, de génomique des populations et de biologie computationnelle pour comprendre comment les éléments transposables façonnent les génomes et l’adaptation des organismes. Après une thèse (2008-2013) réalisée à l’Université de Buenos Aires, il rejoint l’équipe de Vincent Colot à l’Institut de biologie de l’École normale supérieure à Paris comme chercheur post-doctoral, où il étudie le contrôle épigénétique des éléments transposables. Recruté au CNRS en tant que chargé de recherche en 2017, il crée et dirige depuis 2021 l’équipe « Génomique et épigénomique des plantes » au sein de l’Institute of Plant Sciences Paris-Saclay - IPS2 (CNRS/INRAE/UEVE/UPSaclay, Gif-sur-Yvette). Grâce au programme Momentum du CNRS et une ERC Starting Grant, son équipe a mis en place des approches expérimentales et bio-informatiques pour suivre l’activité des éléments transposables dans des populations entières de plantes et en réponse aux changements environnementaux. Ses travaux ont été récompensés par la médaille de bronze du CNRS en 2021 et ont contribué à positionner son équipe comme un acteur majeur de l’étude des « gènes sauteurs » chez les plantes.   Le projet « HosTEome » s’intéresse aux éléments transposables (ETs) dans le génome des plantes, parfois appelés « gènes sauteurs », qui sont des séquences d’ADN capables de changer de position et de se multiplier dans le génome. Longtemps considérés comme de l’« ADN poubelle », ils sont aujourd’hui reconnus comme des moteurs essentiels de l’évolution, et occupent une part importante des génomes de la plupart des organismes. Jusqu’à présent, la recherche s’est surtout concentrée sur les mécanismes associés à leur mobilisation, sur leurs impacts en termes de mutations génétiques, et sur les mécanismes épigénétiques qui les maintiennent sous contrôle. Pourtant, les ETs ne sont pas de simples séquences répétées : ils codent des protéines spécialisées qui catalysent leur déplacement et interagissent avec l’environnement cellulaire. La nature de ces interactions et leur impact sur la capacité des ET à se propager restent cependant largement méconnus.   Le projet « HosTEome » vise à mieux comprendre comment les protéines des ETs et celles de leurs génomes-hôtes s’influencent mutuellement, et comment ces relations contribuent, à long terme, à façonner la structure et l’évolution des génomes. Pour cela, le projet mobilisera des approches de protéomique, d’interactomique, d’épigénomique, de bioinformatique, et de génomique guidée par l’intelligence artificielle, afin d’explorer ces interactions et leur diversification à grande échelle au cours de l’évolution des eucaryotes.   ->Contact : leandro.quadrana@universite-paris-saclay.fr
