Abstract
The distribution and propagation of Zucchini yellow mosaic virus (ZYMV) within Styrian pumpkin plants (Cucurbita pepo L. subsp. pepo var. styriaca GREB.) was studied for one week starting 6 hours after ZYMV-inoculation using transmission electron microscopy (TEM). By negative staining, virus particles were found within the cotyledons and its petioles four days after the inoculation and within the whole plant seven days after the infection. Two weeks after ZYMV-inoculation the cytoplasm of infected leaf and stem cells showed typical features of ZYMV like cylindrical inclusions and proliferated endoplasmatic reticulum. No ZYMV-induced modifications were found within root cells.
