PlantStressLab - Francesca Secchi
Associate Professor in Plant Physiology
She has expertise in molecular plant physiology. Her current research focuses on whole woody plant water relations, sugar metabolism, structure and function of plant vascular network and abiotic plant stress biology.
PB-PINE: Short and long term effects of prescribed burning on soil-plant system in alpine forest stands (Pinus sylvestris L.)
MITIWOOD: Holistic understanding of xylem recovery from water stress to mitigate future climate impact on woody plants
MicroCT-xRec: The main goal of the proposed research is to use concurrently physiological treatments and in vivo 3-D micro-tomography to gain mechanistic insight into biological activity of poplar vessels-parenchyma complex during the cycle of embolism and subsequent recovery of hydraulic conductivity (recovery).
