“…In addition to changes in chloroplast inner structures including decrease in area of thylakoid systems, enhanced stromal area, accumulation of starch and induction of plastoglobuli were also observed (Zechmann et al, 2003). Moreover, infection with the 0 strain of Potato virus Y (PVY 0 ) changed the number of mitochondria and microbodies in potato plants of cultivar Quarta (Hinrichs-Berger et al, 1999). Long-term plum pox virus (PPV) infection in peach plants produced an alteration primarily in chloroplast ultrastructure, increasing plastoglobuli and dilation of thylakoid membranes (Hernàndez et al, 2004).…”

“…Parallel to the assembling of noncapsidated particles, it can be a result of host-plant defense reaction. Hinrichs et al (1998) and Hinrichs-Berger et al (1999) suggested that resistant plants interaction, the reaction is so quick and there is no time for virus cytoplasmic inclusions formation, as it is in this case, for complete particles formation. It seems that viral inclusions are not absolutely required for PVY genome replication or for cell-to-cell transport of the pathogen.…”

“…Taking into account specificity and speed of infection, it was proposed to distinguish interaction compatible and incompatible between host-plant and virus (Hinrichs-Berger et al 1999;Garcia-Brugger et al 2006). Pathogen causes disease if there is compatibility between pathogen and plant.…”

Potato plants cv. Rywal with hypersensitivity gene Ny-1 infected with PVY N or PVY NTN reacted in local necroses 3 days after infection. Potato virus Y (PVY) particles were found in epidermis, mesophyll, phloem and xylem cells in inoculated leaves. Noncapsidated virus particles (without capsid protein) were observed already 10 h after infection by using electron microscopy in situ. Capsid protein on one terminus of noncapsidated virus particles was located 5 days after inoculation with the use of immunogold labeling method. Whereas cytoplasmic inclusions were observed for the first time 24 days after infection during hypersensitive response. Ultrastructural studies showed that ER may take part in PVY RNA replication and capsidation of Potyvirus particles. Observed cytopathological changes and virus particles indicate that cell nucleus and mitochondrion might participate in PVY life cycle. During hypersensitive response PVY particles were found in plasmodesmata as well as in phloem and xylem.

“…Callose deposition was also observed in living cells of leaf tissues around TMV local necrotic lesions, indicating that it formed a physical barrier to virus movement (Beffa et al 1996;Krasavina et al 2002;Schuster and Flemming 1976;Shimomura 1979;Shimomura and Dijkstra 1975;Stobbs et al 1977;Wu and Dimitman 1970). Similarly, callose deposition was also detected around local lesions in potato plants infected with Potato virus Y (PVY) (Hinrichs-Berger et al 1999), in Sorghum bicolor infected with Maize dwarf mosaic virus (Choi 1999), and in Gomphrena globosa infected with Potato virus X (PVX) (Allison and Shalla 1974;Pennazio et al 1981). However, Shimomura and Dijkstra (1975) reported that callose deposition was observed in the walls of initially infected leaf epidermal cells before local lesions were appeared in Nicotiana glutinosa infected with TMV.…”

Callose deposition at plasmodesmata is a critical factor in restricting the cell-to-cell movement of Soybean mosaic virus

Callose is a β-l,3-glucan with diverse roles in the viral pathogenesis of plants. It is widely believed that the deposition of callose and hypersensitive reaction (HR) are critical defence responses of host plants against viral infection. However, the sequence of these two events and their resistance mechanisms are unclear. By exploiting a point inoculation approach combined with aniline blue staining, immuno-electron microscopy and external sphincters staining with tannic acid, we systematically investigated the possible roles of callose deposition during viral infection in soybean. In the incompatible combination, callose deposition at the plasmodesmata (PD) was clearly visible at the sites of inoculation but viral RNA of coat protein (CP-RNA) was not detected by RT-PCR in the leaf above the inoculated one (the upper leaf). In the compatible combination, however, callose deposition at PD was not detected at the site of infection but the viral CP-RNA was detected by RT-PCR in the upper leaf. We also found that in the incompatible combination the fluorescence due to callose formation at the inoculation point disappeared following the injection of 2-deoxy-D-glucose (DDG, an inhibitor of callose synthesis). At same time, in the incompatible combination, necrosis was observed and the viral CP-RNA was detected by RT-PCR in the upper leaf and HR characteristics were evident at the inoculation sites. These results show that, during the defensive response of soybean to viral infection, callose deposition at PD is mainly responsible for restricting the movement of the virus between cells and it occurs prior to the HR response.
