Poll pausing and epigenetic regulation of transcription in Arabidopsis

The precise and coordinated regulation of gene expression, as well as its epigenetic maintenance during cell divisions, is central to the development of the organism and its response to stimuli from the environment. Recently, RNA Polymerase II (PolII) pausing has been shown to play important roles in gene expression, RNA processing and chromatin organization in animals. Evidence that PolII pausing also occurs in plants is still lacking. Based on encouraging preliminary results from Scott Michaels' group, we will evaluate if PolII pausing occurs in Arabidopsis thaliana and how it could interact with transcriptional and epigenetic mechanisms using genome-wide approaches and bioinformatics.

Biography & research interests

After obtaining my diploma of engineering in agronomy and my MSc at Agrocampus Ouest (2000), I obtained my PhD, on transcriptional regulation by nuclear receptors (PPARalpha and RXR, supervisor: T. Pineau) in 2007. I was appointed research engineer at INRA during my PhD (2004) and I co-directed the group of Integrative Toxicology & Metabolism for 4 years (20072011). I next created a transcriptomic platform at INRA ToxAlim (2011-2013). During these years, I led significant research projects that contributed to the development of ToxAlim. In 2013-2015, I joined the group of Olivier Cuvier, where I studied chromatin organization and transcription in Drosophila cells using various genome-wide approaches based on NGS. Thanks to the AgreenSkills+ program, I then joined the group of Scott Michaels at Indiana University (2015-2017) where we studied a new family of transcription elongation factors and deciphered their role on RNA polymerase II processivity, chromatin organization and gene expression. Throughout my career, I have balanced biology with bioinformatics and biostatistics and gained experience in the production and analysis of different types of microarray and NGS data.
