Biography

Guido Sessa received his B.Sc. in Agriculture from The Hebrew University of Jerusalem, and M.Sc. and Ph.D. in plant genetics from the Weizmann Institute of Science. From 1997 to 2000, he carried out a postdoctoral training at Purdue University and Cornell University. Since 2000, he is a faculty member at the Dept. of Molecular Biology and Ecology of Plants at Tel Aviv University.

Research Interests

The main interest of the Sessa laboratory is to study of molecular mechanisms that govern plant immunity and susceptibility to bacterial pathogens. On the plant side, we use molecular biology, functional genomics and proteomics approaches to dissect recognition events and signal transduction pathways that mediate immunity. On the bacterial side, we apply genetic and biochemical strategies to unveil the mode of action of bacterial virulence factors that manipulate host functions. Our investigation has a direct impact on agriculture by providing targets and biotechnological strategies for the development of disease control against economically important pathogens.
