Islam1, Dilip M. Shah1, Kaoutar El-Mounadi2 1Donald Danforth Plant Science Center, 2Department of Biology, Kutztown University of Pennsylvania Plant defensins play an important role in plant defense against pathogens. For effective use of these antifungal peptides as antifungal agents, understanding their modes of action (MOA) is critical. Here, a live-cell imaging method is described to study critical aspects of the MOA of these peptides. Biology Identification of Intracellular Signaling Events Induced in Viable Cells by Interaction with Neighboring Cells Undergoing Apoptotic Cell Death Snezana Vujicic*1,2, Lanfei Feng*1,2, Angelika Antoni3, Joyce Rauch4, Jerrold S.

The protocol focuses on signaling events induced by receptor-mediated recognition of the dead cells, as opposed to their phagocytic uptake or release of soluble mediators.
