Viruses or mutation? Other plants that do not show symptoms

Tomato    Italia

The leaves are all with such symptomatology. Other plants that do not show symptoms.

This to me looks like a physiological stress. You can notice the yellowing (called chlorosis) between the veins. Was this plant purchased at the same time as the others? Is it likely to be a different genetic background?

Are the plants in pots or are they in the ground. If they are in the ground then the other plants seem healthy and it is likely not physiological (unless the plant is a different genetic background)

It could be viral of course. Have you seen aphids? Do you smoke? Tomato plants can get mosaic virus if the grower smokes.

Provide more images of the close up of the leaf. Check the plant and tell me if the lower leaves are more affected or the higher leaves.

Dr. Raffaele Giurato commented,
plants on the soil. The basal leaves are healthy or slightly affected.
Firmly I rule out that it is physiological stress.

the cultivar is tolerant (HR) to ToMV but not to TMV.
Yes, the farmer is smoker but I exclude it from the symptoms of TMV. In addition there should be nearby plants infected instead there are other plants in the greenhouse.

It is Pepino mosaic virus. The symptoms are very similar. However I do not understand why any plant nearby is not infected ( transmits mechanically).

It could be genetic mutation of the plant ???

The leaves do not show blistering and / or deformation. Chlorosis differing from those of stressed plants.
It is Pepino mosaic virus?

I dont think a virus can be classified according to group from an image. It could be as you say, but you would need a diagnostic test to be sure.
