Molecular Plant Physiology

Plants are able to perceive the signals provided by the light environment. These signals affect key aspects of plant physiology and plant yield. The aim of our group is to know and functionally understand the signalling networks linking photo-receptors to the points of control of plant body shape and function. Our idea is that the complexity of the signalling networks is justified by the complexity of the light environment that plants have to face. We use techniques of molecular biology, analysis of the transcriptome, genetics and cell biology in combination with light treatments that simulate selected aspects of the environment experienced by plants.
