“…In contrast, there were no changes of the permeability of cell membranes in the sensitive tobacco plants infected with TMV during 5 d.p.i. (Weststeijn 1978). We also found no differences in the permeability of cell membranes between the samples from DGI, LGT and similar leaves of healthy Table 1.…”

“…The permeability of cell membranes increased during local lesion formation on leaves of hypersensitive plants infected with viruses (Ohashi and Shimomura 1976, Pennazio et al 1979, Weststeijn 1978. Moreover, the permeability of cell membranes was higher not only in necrotic cells, but also in living cells bordering with local lesions (Seletskaya et al 1996).…”

There are significant changes in the structure of the upper tobacco (Nicotiana tabacum L.) leaves systemically infected with tobacco mosaic virus (TMV) especially in the light green tissue (LGT). Dark green areas (DGI) had intermediate status between healthy tissue and LGT. DGI contained significantly less infectious TMV and viral antigen than the LGT. The DGI, LGT and healthy tissues did not differ in the permeability of cell membranes and in the set of acidic pathogenesis-related (PR) proteins but the total content of PR-proteins in the healthy plants was higher than in the infected ones with the DGI being intermediate between healthy tissue and LGT. The crude leaf extracts from DGI and LGT showed less total ribonuclease activity and ribonuclease isozymes in comparison with control.

“…At the cellular level, HR affects calcium (Ca 2+ ) ion homeostasis and alters membrane potential and permeability (Mur et al, 2008). For example, TMV and turnip crinkle virus (TCV) infections both induce callose deposition at the plasmodesmata and alter membrane permeability permitting electrolyte leakage in tobacco and Arabidopsis, respectively (Weststeijn, 1978;Ueki and Citovsky, 2005;Culver and Padmanabhan, 2007;Carr et al, 2010;Pallas and García, 2011;Zavaliev et al, 2011). Furthermore, during HR, several caspase-like proteinases, such as the vacuolar processing enzymes, are activated.…”

Plant Immune Responses Against Viruses: How Does a Virus Cause Disease?

Plants respond to pathogens using elaborate networks of genetic interactions. Recently, significant progress has been made in understanding RNA silencing and how viruses counter this apparently ubiquitous antiviral defense. In addition, plants also induce hypersensitive and systemic acquired resistance responses, which together limit the virus to infected cells and impart resistance to the noninfected tissues. Molecular processes such as the ubiquitin proteasome system and DNA methylation are also critical to antiviral defenses. Here, we provide a summary and update of advances in plant antiviral immune responses, beyond RNA silencing mechanisms-advances that went relatively unnoticed in the realm of RNA silencing and nonviral immune responses. We also document the rise of Brachypodium and Setaria species as model grasses to study antiviral responses in Poaceae, aspects that have been relatively understudied, despite grasses being the primary source of our calories, as well as animal feed, forage, recreation, and biofuel needs in the 21st century. Finally, we outline critical gaps, future prospects, and considerations central to studying plant antiviral immunity. To promote an integrated model of plant immunity, we discuss analogous viral and nonviral immune concepts and propose working definitions of viral effectors, effector-triggered immunity, and viral pathogen-triggered immunity.

“…PO may be involved in lipid peroxidation (KATO 1976) and/or the alteration of membrane permeability (WESTSTEIJN 1976) in stressed tissue. Lipid peroxidation in cowpea results in ethylene formation from linolineic acid (KATO 1976), but this is questionable in tobacco leaves (DE LAAT et al 1981).…”
