Résumé:
L'interaction entre les petits ARN et d'autres ARN non codants (ncRNA), les marques de chromatine et les facteurs de transcription jouent un rôle décisif dans le contrôle de l'expression des gènes. Au cours des dernières années, des petits ARN ont été reliés à des changements épigénétiques et à la régulation post-transcriptionnelle dans une variété de processus de différenciation et / ou de maladies chez les eucaryotes. La capacité des plantes à adapter leur croissance aux stimuli environnementaux grâce à des modifications épigénétiques qui pourraient être transmises à leur descendance, renforce leur utilisation pour l'élucidation de ces mécanismes de régulation. L'objectif principal de ce projet est de comprendre l'action des petits et longs ARN non codants dans l'expression des gènes et la régulation épigénétique, ainsi que la dynamique de ces régulations ncRNA-dépendantes chez les plantes. Nous avons modifié les profils d'expression d’enzymes spécifiques qui contrôlent la production de petits ARN et nous avons caractérisé de nouvelles cibles épigénétiques potentielles de ce mécanisme par des approches « genome-wide » Cela a permis d’approfondir l'analyse de la grande utilité de cette technologie dans l’identification de nouvelles cibles en agriculture. Nous avons également identifié de nouveaux liens entre la régulation de la chromatine et les longs ARN non codants, ainsi qu'une connexion inattendue avec la régulation de l'épissage alternatif. Par conséquent, nous apportons une base pour aborder la manière dont le répertoire des ncRNA et/ou la machinerie liée à l’ARN peuvent améliorer le potentiel épigénétique des plantes.
