Is DNA present in tobacco mosaic virus?

Tobacco Mosaic Virus (Virgaviridae)☆ TMV-resistant plants have been obtained by transforming them with a DNA copy of the TMV coat protein gene.

Where does tobacco mosaic virus come from?

TMV is very easily transmitted when an infected leaf rubs against a leaf of a healthy plant, by contaminated tools, and occasionally by workers whose hands become contaminated with TMV after smoking cigarettes.

Symptoms associated with TMV infections:stunting.mosaic pattern of light and dark green (or yellow and green) on the leaves.malformation of leaves or growing points.yellow streaking of leaves (especially monocots)yellow spotting on leaves.distinct yellowing only of veins.

Can plants carry human viruses?

The answer is simply, no. Since plants are not a susceptible host for the virus that gives us the flu. VIruses are incredibly host specific, so we can’t get sick with a plant virus and plants can’t get sick with an animal virus. However, that doesn’t mean we don’t “spread” viral diseases to plants.

Does mosaic virus stay in soil?

Tomato mosaic virus and tobacco mosaic virus can exist for two years in dry soil or leaf debris, but will only persist one month if soil is moist. The viruses can also survive in infected root debris in the soil for up to two years.
