Individual Research Project 4. Non-genetic phenotypic plasticity induced by light acclimation under the supervision of Fredy Barneche at Institut de Biologie de l'Ecole Normale Supérieure (IBENS) and Sorbonne University (SU)in Paris, France.

It is a project about short-term priming and transgenerational acclimation to light stress. The host laboratory identified that gene induction during Arabidopsis photomorphogenesis is enhanced by a prior, short and transient, exposure to light. The physiological relevance and molecular mechanisms underlying light-induced plant priming have not been addressed, nor its links to other priming mechanisms. The process could significantly favour seedling vigour in agriculture under extreme light conditions (heat waves, high altitude, low latitude).

The objectives of the Project are:

  • to contrast and compare epigenome and transcriptome/epitranscriptome changes induced by short-term priming in Arabidopsis and oilseed rape plants.
  • to characterise gene regulatory pathways impacting light-induced priming and transgenerational effects of high light acclimation.

In these analyses, you will use Arabidopsis chromatin and photoperception mutant lines and benefit from a unique collection of Arabidopsis wild type and mutant lines with different life histories of light environment for five successive generations.

Active collaboration with partners at the University of Amsterdam (Netherlands), Regensburg (Germany), and DSV (Deutsche Saatveredelung AG, Germany) to get not only specific training in molecular and industrial approaches but also intellectual input that will be valuable to the progress of the project.

ENS and SU- Host Institutions

Ecole Normale Supérieure (ENS) is a small and historical French institution located in the centre of Paris. ENS is dedicated to training through research with a multidisciplinary and international perspective with 300 foreign researchers and 650 PhD students. ENS is a founding member of Paris Sciences Lettres (PSL) University, ranked among the top 5 young universities under 50 years of age in the THE (Times Higher Education) and QS (Quacquarelli Symonds) rankings (2019-2021), and the 38th best university according to the 2021 Shanghai ranking.

Sorbonne University (SU) is a public research university located in Paris, France. The institution represents one of the first universities in Europe, reaching back to the Middle Ages in 1257.t universities in Europe. As of 2021, Sorbonne’s alumni and professors have won 33 Nobel Prizes, six Fields Medals, and one Turing Award.
