In metazoans, autophagy is an essential component of host defense against viruses, orchestrating their degradation. Such antiviral functions for autophagy have also been long suspected in the green lineage. Two recent reports provide molecular insights on how plants selectively send viral proteins and even particles to the vacuole.

自噬：对抗植物病毒的双刃剑

在后生动物中，自噬是宿主防御病毒，协调其降解的重要组成部分。这种自噬的抗病毒功能在绿色血统中也早已被怀疑。最近的两份报告提供了有关植物如何选择性地将病毒蛋白甚至颗粒传递至液泡的分子见解。
