[6] These include other vegetables such as squash, melons, peppers, eggplants, tomatoes,[7] beans,[8] carrots, celery, lettuce, spinach,[9] beets, many ornamentals and bedding plants, such as Narcissus,[10] and various weeds.

[citation needed] Tomato plants are usually stunted and have poorly shaped leaves, or "fernleaf", when infected by CMV.

Pepper plants often have severe foliar damage, shown as mosaic and necrotic rings.

[16] CMV was also detected on American beautyberry, an important wildlife and pollinator food source plant native to North America.

[18] In plant tissue this virus makes characteristic viral inclusion bodies which can be diagnostic.

[21] A reduction of crop yield can affect mechanisms such as photosynthesis and its ability to provide oxygen to the environment.

Then, proteins 1a and 2a are produced to enable the virus replication, which takes place in viral factories, which are subcellular compartments which increase the efficiency of this process.

There, a dsRNA genome is synthesized from the ssRNA(+) and transcribed in order to obtain viral mRNAs as well as new ssRNAs.

Finally, the virus is ready to move to a new cell by triggering the formation of tubular structures which mediate the movement of the virions [1].

The short-distance (cell-to-cell) movement of the virus is achieved via plasmodesmata, while the long-distance one (within the plant) occurs via the phloem.

[31] In addition to its presence in temperature areas, this virus can also be found in more tropical climate zones.

[32] The presence of this virus in a plant can be confirmed serologically (ELISA), molecularly (PCR), or by host range tests.

Biological assays can also be performed to determine the specific variants of CMV affecting the plant.

This virus can negatively affect the health and sustainability of agriculture such as crops like tomatoes, peppers, and lettuce.

[36] To achieve this, it is crucial to remove weeds and diseased plants from the field, as well as use clean and sanitized tools.
