Description of the thesis topic

In challenging situations like in the shade of competitive neighbors or under high ambient temperature, plants elicit elongation of their vegetative organs like hypocotyls. To fuel growth, plants need nutrients like nitrogen, which for many species is taken up by roots as nitrate ions. Despite its critical role for plants, nitrate in excess can be potentially harmful for the environment. It is crucial to understand how plants deal with nitrate supply and how it impacts their development, especially in constraining environments. The main objective of this project is to understand how shade or high temperature affect nitrate homeostasis.

To do so, the PhD candidate will analyze the different steps of nitrate metabolism in plants subjected to shade or elevated temperature (uptake, transport and assimilation) and identify which actors of the nitrate pathway (metabolism and signaling) are required for adapted growth responses upon exposure to shade or high temperature.

The PhD candidate should have a Master degree in plant biology. A good knowledge in plant physiology and molecular biology is required, as well as motivation for the subject. Knowledge in biostats is a plus. Communication skills will be appreciated.

Work Context

The future PhD student will work within the Institute of Integrative Biology of the Cell (I2BC), in the Cell Biology department, in the team "Integrative Approaches to Ion Transport".

The I2BC is a joint CNRS-Paris-Saclay University-CEA research unit located on the CNRS campus in Gif-sur-Yvette, near Paris. This institute, which is composed of 600 people, brings together basic research teams organized into 5 departments (Cell Biology, Genome Biology, Virology, Microbiology, Biochemistry-Biophysics-Structural Biology) as well as several cutting-edge technological platforms.

The "Integrative approaches to ion transport" team is developing various research projects aimed at understanding the properties of ion transport systems in plants at different scales (molecular, cellular, organism) and using different models (Arabidopsis, Poplar, Noccea, etc.). The team is also part of the SPS Labex (Sciences des Plantes de Saclay), which brings together 50 plant science research teams in southern Paris.

The doctoral student will join the PLANT SCIENCES: FROM GENE TO ECOSYSTEM (SEVE) doctoral school at Paris-Saclay University.
