**Elisabeth Jamet**

Elisabeth Jamet gained a Ph.D. in 1985 at Strasbourg University (France) on so-called plant-pathogenesis-related proteins. She was the first to be able to purify these proteins which were considered at that time as degradation products due to their great stability. She was hired as a permanent researcher at the National Center for Scientific Research (CNRS) in 1986 at the Institute of Plant Molecular Biology (IBMP) in Strasbourg. She then developed a research project dealing with plant cell dedifferentiation through protoplasts. She focused on the role of the cell wall in protoplast recovery, a critical step to acquire the capability to divide, form a callus, and regenerate a plant. In 2001, as a research director at CNRS, she moved to the Plant Science Research Laboratory (LRSV) close to Toulouse (France) where she developed her own team focusing on the role of cell wall proteins in plant development. She has greatly contributed to the establishment of diverse strategies to characterize the plant cell wall proteome, including experimental approaches and bioinformatics treatment of mass spectrometry data. In parallel, she has contributed to the unraveling of the function of several families of cell wall proteins, notably the PAC (proline-rich, arabinogalactan proteins, conserved cysteines) domain proteins. She is presently the co-leader of the Dynamics and Evolution of Plant Cell Walls team at LRSV. She has co-authored 100 articles in international journals, and she is an editor of *Frontiers in Plant Science*, the *International Journal of Molecular Science*, and *Cells*. She has been/is a member of different scientific evaluation committees at national and international levels. She was the head of LRSV between 2011 and 2015, and she presently exercises responsibilities at Toulouse University.

### **Christophe Dunand**

Christophe Dunand gained a Ph.D. in 1997 at Grenoble University (France) in plant biochemistry. He has demonstrated the binding and biological effects of oligosaccharides on the enzymatic activity of plant protoplast extracts. After gaining his Ph.D., he completed three post-doctoral internships. First, he completed 1 year at the University J. Fourier (Grenoble) on Arabidopsis floral development and then 18 months at the University of Connecticut on the study of cell walls. In 2000, he joined the Plant Physiology Laboratory of Geneva University as an assistant professor. Until 2008, he strongly developed bioinformatics and molecular biology approaches dedicated to plant peroxidase genes. He was hired as a full professor at the University of Toulouse in 2008 at the Plant Science Research Laboratory (LRSV) close to Toulouse (France). He then developed his own team to continue studies on plant peroxidase functions and evolution. His research interests mainly focus on the model plant Arabidopsis, and his research has taken a more integrative direction with the use of less typical models and approaches such as hepatic or aquatic plants. He is presently the co-leader of the Dynamics and Evolution of Plant Cell Walls team at LRSV. He has co-authored 90 articles in international journals, and he is an editor of *Frontiers in Plant Science*, the *International Journal of Molecular Science*, and *Cells*.
