Elaboration of the quality of grain components in plants: molecular and physiological regulations in response to environmental constraints linked to global warming (defended on December 13th, 2021)

Jane Roche’s tenure track focused on the elaboration of the quality of grain components in plants; and more particularly molecular and physiological regulations in response to environmental constraints linked to global warming through the study of two signalling pathways: the UPS pathway (Ubiquitin Proteasome 26S) and the UPR pathway (Unfolded protein Response). These two pathways, involved in the maturation of proteins in the cytosol (UPS) and endoplasmic reticulum (UPR), are used to ensure cellular protein homeostasis in the developing plant. The aim is to understand their role in response to abiotic stress (temperature rise and/or water stress); and, in the accumulation of the storage proteins in the bread wheat grain (Triticum aestivum), proteins guaranteeing flour quality and the formation of gluten during the baking process in particular.

Thus, through the identification of the major genes involved in these pathways, their interaction and the validation of their function, this work will lead to develop a model of molecular physiology for the response to global warming in wheat trying to answer to the future agricultural and societal challenges.
