Summary[edit] Description: English: Descriptor: Symptoms of tobacco vein mottling virus (TVMV) (Potyvirus TVMV) Description:The initial symptom of TVMV infection is a slight, barely visible clearing on expanding leaves. Subsequently, leaves develop irregular green patterns of mottling adjacent to the veins; this is most evident on the ruffles at the base of older leaves. Chlorosis of infected leaves is extensive, giving the plants a pale green or yellow appearance which may be evident from a distance. Necrotic spotting of the leaf, indistinguishable from weather fleck, may develop and become increasingly prevalent as plants mature. The earlier that plants are infected with the virus, the greater the damage. The virus overwinters in perennial solanaceous weeds and is transmitted to tobacco by aphids. The virus is often found in combination with TEV. TVMV is also one of the most prevalent viruses in burley. Image type:Field Host:burley tobacco (Nicotiana tabacum (burley type) L.).

Summary[edit] Description: English: Striped zucchini with Zucchini Yellow Mosaic Virus. The plant produced well for two months, then the new leaves had the mosaic pattern and the plant didn't produce any fruit. Then I hand-pollinated the fruits, and this was the result: a stunted, 8.5 inch fruit with the characteristic distorted shape of ZYMV. From a garden in Los Angeles, California.

Summary[edit] Description: English: Descriptor: Symptoms of tobacco etch virus (TEV) (Potyvirus TEV) Description: The first symptom of TEV infection is a pronounced vein clearing on expanding leaves. This is followed by necrosis of a thin line of tissue along the veins, resulting in an etched pattern. Subsequently, young leaves develop a mosaic which fades to mottling as the leaf ages. Etching and more pronounced veinal necrosis is common. Plant growth is retarded, resulting in stunting, especially when young plants are infected. The virus overwinters in perennial solanaceous weeds and is transmitted to tobacco by migrating aphids. TEV often occurs in combination with other aphid-borne viruses. Tobacco etch is one of the most common virus diseases of burley. Image type: Field Host: Burley tobacco (Nicotiana tabacum (burley type) L.). Date: 19 November 2002, 12:31:36. Source: R.J.

Summary[edit] Description: English: Viral RNA pathways in infected cell. In a newly infected cell, polysomes translate viral RNA (vRNA, pathway 1), and it is recruited to VRCs (pathway 2). The replicated vRNA is transported to plasmodesmata to facilitate cell-to-cell movement (pathway 3). To achieve productive infection, vRNA expression continues via new rounds of translation/replication (pathway 4). Host cell defense mechanisms leading to RNA degradation actively compete for vRNA substrates with viral counterdefense mechanisms (pathway 5). vRNA encapsidation completes the infection cycle (pathway 6), allowing the encapsidated virus to be transported and infect neighboring healthy plants.
