Pathogenic viruses are a constant threat to all organisms, including plants. However, in plants, a small group of cells (stem cells) protect themselves from viral invasion. Recently, Incarbone et al. uncovered a novel salicylic acid (SA) and RNAi mechanism of stem cell resistance, broadening our understanding of RNAi-mediated antiviral plant immunity.

水杨酸驱动的植物先天抗病毒免疫

致病病毒对包括植物在内的所有生物体构成持续威胁。然而，在植物中，一小群细胞（干细胞）保护自己免受病毒入侵。最近，Incarbone等人。揭示了一种新的水杨酸（SA）和干细胞抗性的 RNAi 机制，拓宽了我们对 RNAi 介导的抗病毒植物免疫的理解。
