Summary :


microscopie electronique In land plants, carbon allocation from the photosynthetic organs to the other organs is an integrative process enabling the plant to adjust the delivery of carbon and energetic resources depending on the plant development and environmental constraints. Thereby, carbon allocation coordinates use and storage of sugars at various scales, from the cell to the whole organism. Our  goal is to determine, in the different plant organs, the mechanisms acting at a cellular and tissular level for the allocation of carbohydrates. We focus on the gene networks involved in this process and their coupling with other nutritional and developmental mechanisms, in relationship with adaptive anatomic and metabolic adjustments.
