Viral Disease T Tobacco Mosaic Virus by Dr. Subrata Giri
Introduction Tobacco mosaic virus (TMV) is a highly infectious plant virus that affects a wide range of plants, including tobacco, tomatoes, peppers, and other members of the nightshade family. It was the first virus to be discovered and is considered one of the most economically significant plant viruses globally. TMV is named after the mosaic-like patterns it creates on the leaves of infected plants, leading to visible discoloration and reduced plant health
Symptoms Mosaic-like patterns on leaves (light and dark green irregular patches). Stunting and reduced plant growth. Curling and distortion of leaves. Necrosis, leading to necrotic streaks or spots. Yellowing and mottling of leaves. Fruit deformities in some infected crops. High contagion through plant contact and insect vectors.
