An example of a virus with helical symmetry is the tobacco mosaic virus, which is the most studied example.

螺旋对称型病毒的典型代表是烟草花叶病毒，这是研究最多的一种病毒。

Experiments on cacti, corn, grapevines and wheat produced similar results, as did tomato plants suffering from an infection of mosaic virus, a common pathogen that can damage yields.

对仙人掌、玉米、葡萄树和小麦进行的实验也产生了类似的结果，感染花叶病毒（一种可能损害产量的常见病原体）的番茄植物也得到了类似的结果。
