Quantitative Interferometry of Epidermal Nuclei of Podophyllum peltatum in Response to Puccinia podophylli. F. B. Kulfinski, Associate Professor, Faculty of Biological Sciences, Southern Illinois University, Edwardsville 62025; A. J. Pappelis, Associate Professor, Department of Botany, Southern Illinois University, Carbondale 62901. Phytopathology 61:237-238. DOI: 10.1094/Phyto-61-237.

Infection of Podophyllum peltatum by Puccinia podophylli produced a 7% increase in nuclear area (x.s.), an 18% decrease in nuclear dry matter concn. and a 14% decrease in total nuclear dry matter of host epidermal cells below infected mesophyll when compared to cells from adjacent “normal” epidermis.
