Symptoms: The leaves of infected plants become smaller, shrunken, distorted and curled backward, showing obvious mosaic symptoms; old leaves turn yellow, flowers become smaller and shriveled, and petals take on a broken-color appearance. In severe cases, the plants are stunted and wither prematurely.

Transmission routes: It can be spread through sap and by various aphids (mainly the green peach aphid and the cabbage aphid). Turnip mosaic virus also harms many kinds of plants.
