Résumé :

TGS du gene GUS Les eucaryotes régulent l’expression génique grâce à des mécanismes d'inactivation épigénétique faisant intervenir des petits ARN de 21-24 nucléotides chlorose due a la PTGS de la nitrite reductase (siRNAs et miRNAs) conduisant soit à un blocage de la transcription (transcriptional gene silencing: TGS), soit à une dégradation des ARN (post-transcriptional gene silencing: PTGS), soit à une répression de la traduction. Les cibles de ces processus sont des éléments exogènes (virus, bactéries) ou endogènes (gènes, transposons, hétérochromatine). Une approche de génétique moleculaire a été entreprise pour identifier les gènes cellulaires contrôlant ces processus et comprendre les mécanismes sous-jacents.

 


Résultats marquants :

chlorose due a la PTGS de la nitrite reductase Nos travaux ont mis en évidence plusieurs protéines cellulaires participant à différents réseaux de silencing : TGS et PTGS des transgènes, atténuation de l’infection virale, régulation post-transcriptionnelle de gènes endogènes par des microRNAs (miRNAs) ou des trans-acting siRNAs (ta-siRNAs), contrôle transcriptionnel des éléments répétés du génome. Outre leur rôle dans la régulation du développement, certains miRNAs et ta-siRNAs participent à des boucles de rétro-action permettant de maintenir l’homéostasie de ces réseaux complexes de régulation.
