Description de l'offre

Photosynthetic organisms (microalgae and plants) are in constant interaction with their environment, responding to various abiotic pressures (temperature, nutrients, light), as well as biotic ones (symbiosis, parasitism). Molecular approaches (‘omics’) have improved our understanding of the adaptive mechanisms to these changes. However, the cellular architecture and structural organisation of organelles such as the chloroplast and mitochondria must be revealed to fully understand how organisms respond to their environment.

3D electron microscopy has become one of the essential approaches for revealing and deciphering the mechanisms of cellular plasticity. Technological advances and cryogenic sample preparation now make it possible to visualise cellular structures, membrane arrangements, contacts between organelles, and macro-complex structures in their cellular context (in situ structural biology). The laboratory Cell and Plant Ph...
