Summer School 2021 - Plant cell walls

Plant cell walls in development, plant-microbe interactions and for the bioeconomy

July 4-10, 2021 – Versailles (France)

The study of the cell wall is an important research frontier in plant biology. Over the past decade, the field has seen major technological and conceptual advances. In addition, the study of cell wall structure and metabolism has become an integral part of the research on plant development and the adaptation to abiotic and biotic stresses. A better knowledge of the cell wall is also essential for the optimization of lignocellulosic biomass processing procedures in the framework of the emerging bioeconomy.

SPS Summer School 2019

This SPS Summer School 2021 is a one-week programme for outstanding and enthusiastic PhD students and young post-docs. It will provide them with an introduction in chemistry, biophysics, molecular and cell biology in relation to the plant cell wall.

This Summer School will bring together 16 to 20 participants from all over the world and offer them the chance to receive scientific training in an international and rather informal atmosphere, facilitating exchanges. This course will involve theoretical lectures delivered by world-class experts and hands on practical courses on state of the art technologies.
