OBITUARIES

Rafael Pont-Lezica
(1940–2011)

Longtime ASPB member Rafael Pont-Lezica, Plant Physiology, Biochemistry and Biotechnology Emeritus Professor at the Université de Toulouse, passed away on September 26, 2011, after losing his fight with cancer. He had studied agronomy at the Universidad Nacional de Cuyo in Argentina and earned a PhD in 1978 at the Université de Gembloux, Belgium.

Rafael began his scientific career as a research assistant in plant physiology at the Universidad Nacional de Cuyo (1966–1971), where his work centered on plant morphogenesis and secondary metabolism. He then became assistant professor in biology at the Fundación Bariloche in Argentina (1972–1977), where he developed an interest in sugar metabolism, particularly in the synthesis of cellulose precursors and protein glycosylation.

He obtained a Humboldt Stiftung Fellowship in Heinrich Kauss’s lab in Kaiserslautern, West Germany (1978–1979). From 1979 to 1988, he was a professor at the Universidad Nacional de Mar del Plata in Argentina, where he cofounded, with Horacio Pontis, the Instituto de Investigaciones Biológicas. His main research topics there were on lectin biosynthesis and protein glycosylation. In the course of his first collaboration with Joe Varner, from Washington University in St. Louis, Missouri, Rafael focused his attention on the study of the plant cell wall. Consequently, he was invited as a visiting professor at Washington University in St. Louis (1987–1991). A crucial result of this fruitful collaboration was the development of the tissue printing technique, which became an alternative to in situ hybridization and immunocytochemistry.

In 1992 Rafael obtained a professorship at the Université de Toulouse and set up his own research group. At the Université de Toulouse, he directed the Plant Science Master’s Program (1999–2004) and the European Marie Curie Training Program SIGNAL (Plant Signaling and Biotechnology; 2001–2005). Following his retirement in 2009, he became emeritus professor. As such, he kept up intense research activity, interacting with his former team, today called Cell Wall Proteins and Development, in reference to his mentorship. Rafael’s main research interest was the identification of Arabidopsis thaliana RGD-containing or integrin-like proteins involved in cell wall–plasma membrane contacts. He also began to work on plant cell wall proteomics. He presented the first overview of cell wall proteins and identified proteins that had never before been described. His most recent contribution was setting up two international research programs, introducing Brachypodium distachyon as a model plant for biomass production in our lab: European Knowledge-Based Bio-Economy (KBBE) and Comité Français d’Évaluation de la Coopération Universitaire et Scientifique avec le Brésil (COFECUB). All these developments led to new insights in plant cell wall biology.

Rafael was a member of numerous scientific groups and councils at the local, national, and international levels: the Fundación Bariloche, the Universidad Nacional de Mar del Plata, the Université de Toulouse, the Ecole Doctorale de Biologie in Toulouse, the Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) in Argentina, among others. Although he developed his career in many different universities and countries, he stayed in touch with colleagues with whom he had worked.

Rafael was an appreciated teacher, always encouraging graduate students, postdocs, and young coworkers in the lab. His sound judgment and numerous personal qualities were valued and called upon by his colleagues and collaborators. As a researcher and a human being, he was enthusiastic and creative, communicating his drive and love of life to those around him.
