Select all of the following which are symptoms of mosaic virus.

Mosaic virus infections are characterized by a distinct set of symptoms that typically manifest in the plant's foliage. The correct choice reflects one of the primary signs of such infections. When plants are infected with mosaic viruses, the leaves often exhibit curling and yellowing, which is due to the disruption of normal cellular functions caused by the virus. This symptom is a direct response to viral interference, affecting chlorophyll production and overall leaf health.

While other options may describe symptoms found in plants affected by different issues or diseases, they do not specifically align with the common effects of mosaic viruses. For instance, deformed fruit and blister-like infections may relate to other viral infections or diseases but are not hallmark symptoms of mosaic viruses. Increased plant growth does not occur with mosaic virus infection; instead, the growth may be stunted or negatively impacted due to viral damage. Understanding these specific symptoms helps in identifying and managing plant health more effectively, especially in the context of viral infections.
