Vertical transmission of plant viruses through seeds has been known for a century, yet the mechanism for seeds to combat viral infection remains unclear. In this issue of Cell Host & Microbe, Liu and Ding demonstrate the genetic requirement of RNA silencing (RNAi) pathway for plants to suppress seed transmission.

RNAi，一把植物种子之剑，用于对抗病毒感染


植物病毒通过种子垂直传播已经有一个世纪的历史，但种子对抗病毒感染的机制仍不清楚。在本期的Cell Host & Microbe中，Liu和Ding展示了植物抑制种子传递的RNA沉默（RNAi）途径的遗传需求。
