RESEARCH SUBJECTS
Epigenetic regulation of plant-microbe symbioses: We study the role of epigenetic modifications and regulators in the establishment of symbioses between plants and microorganisms. In particular, we explore the molecular mechanisms by which long non-coding RNAs participate in the remodeling of transcription and chromatin structure during the development of the nodule, a symbiotic nitrogen-fixing organ produced by the symbiosis between legumes and rhizobia bacteria. For this, we combine approaches of molecular biology, genetics, transcriptomics, epigenomics, and microscopy.

Matthias Benoit obtained his PhD in Physiology and Molecular Genetics in the Genetics, Reproduction and Development laboratory (GReD, Clermont-Ferrand, France), supervised by Dr. Aline V. Probst. His work has demonstrated the importance of histone variants in the organization of chromatin during developmental transitions in plants, in particular during the early development of the model plant Arabidopsis thaliana. He then joined The Sainsbury Laboratory Cambridge University (SLCU, Cambridge, UK) and the team of Jurek Paszkowski to study the epigenetic and environmental mechanisms involved in the control of transposable elements in cultivated plants. Matthias completed his training by joining the team of Zach Lippman (Cold Spring Harbor Laboratory, New York, USA) to conduct work on the importance of epigenetic and structural variation during the domestication and evolutionary history of the tomato.

I am working on the pioneer transcription factor NF-YA1 in symbiotic nodules
TRAINING
Thi Thu Dang did her PhD in the lab of Plant Molecular Genetics, Nara Institute of Science and Technology (NAIST, Japan), 2009-2013. Her PhD project was to characterize the Constitutively Active OsRac1 (CA-OsRac1), a master regulator in rice immunity, generated by homologous recombination. From 2015-2017, she then did her first postdoc in the lab of Plant Immunity Signaling, Shanghai Center for Plant Stress Biology, China. There, she continued to study the down-stream regulator of OsRac1, called OsGAPC3, which plays an important role in NO-pathway and histone modification. From 2017 to 2020, she joined the Conserto team, INRAE, Angers for her second postdoc. The project focused on the identification of the protein network regulating ABI4, a transcription factor controlling seed chlorophyll content and longevity. Since October 2020, Thu joined the ENOD group to work on the “PIOSYM” ANR project aiming to evaluate the importance of NF-YA1 as a pioneer transcription factor regulating the formation of symbiotic nodules in Medicago.
