    All types of living organisms including animals, plants, fungi, and bacteria are hosts for viruses, but most viruses infect only one type of host. Viruses cause many important plant diseases and are responsible for losses in crop yield and quality in all parts of the world.

    The age of the plant at the time of infection can be a critical factor in determining symptom expression. In general the younger the plants the more it is susceptible to virus infection and very old leaves or old plants are usually relatively resistance to infections.

    Typical leaf symptoms of viral diseases include mosaic patterns, ring spots, yellowing, stripes or streaks vein clearing, vein banding, and leaf rolling and curling.

    Mosaic patterns:
    This virus infects more than 150 types of plants, including many fruits, vegetables, and flowers. It is characterized by leaves mottled with yellow, white, and light and dark green spots or streaks. Some of the most commonly infected plants include tomatoes, squashes, cauliflower, and cucumbers.

    Viral diseases are difficult to identify because symptoms vary from plant to plant and may also vary depending on the age of the plant and its growing conditions. However, the most common ways of identifying mosaic viruses are listed below.

      ■ This gives the leaves a blister-like appearance.
      ■ Plants are often stunted, or they grow poorly.
      ■ Plants may have other deformities and their leaves may be crinkled or wavy.

      Mosaic viruses are mostly spread by insects, especially aphids and leafhoppers.

      Ring Spots :
      Mainly this disease found in Papaya. In papaya, leaves develop prominent mosaic and chlorosis on the leaf lamina, and water soaked oily streaks on the petioles and upper part of the trunk.
      Severe symptoms often include a distortion of young leaves which also result in the development of a shoestring appearance that resembles mite damage.
      Trees that are infected at a young stage remain stunted and will not produce an economical crop.  Fruit from infected trees may have bumps similar to that observed on fruit of plants with boron deficiency and often have ‘ringspots’

      Vein clearing :
      A symptom of some virus diseases of plants in which the veins become unnaturally clear or translucent.

      Vein Banding:
      A symptom of some virus diseases of plants in which bands of lighter or darker colour occur along the main veins of a leaf.

      Flower, Fruit and Vegetable symptoms:
      Flower symptoms include deformation and changes in the colour of the flowers including dramatic colour mosaics called colour breaking. Fruit and vegetable symptoms may include mosaic patterns, stunting, discolouration or malformation, and chlorotic ring spots.

      Stems of plants may develop stem pitting and grooving or tumours in response to virus infection.
      The end result of virus infection is a reduction in plant growth, lower yield, inferior product quality, and economic loss to individuals who work in the plant industry. Most of the symptoms induced by viruses can also occur due to adverse environmental conditions or diseases caused by other plant pathogens.
