If a tomato plant gets a leaf disease, it can tell nearby plants about it.

番茄植株如果发生叶病，可以告诉附近的植株。

If you seal the tops of tomato plants in airtight plastic bags and expose one of them to a harmful leaf disease, the healthy plants will detect their neighbors' illness and begin making antibiotic compounds.

如果你用不透气的塑料袋把番茄们的茎叶部分密封起来，然后把一株番茄暴露在有害的叶子病毒里，健康的植物们就会检测到它们邻居得的病，然后开始产生抗生素。
