Abstract

Whether mobile virus-derived siRNAs can pre-immunize uninfected plant tissues has been a long-standing assumption in plant biology. In this issue, Albertini et al. demonstrate that they indeed establish an AGO1-dependent immune zone of adjacent uninfected short-range cells, and this mobile pre-immunization is impacted by viral suppressors of RNA silencing.

植物病毒衍生的sirna比病毒的短距离传播领先一步

移动病毒衍生的sirna是否能够预先免疫未感染的植物组织一直是植物生物学中一个长期存在的假设。在这一期中，Albertini等人证明他们确实在邻近未感染的短距离细胞中建立了ag1依赖的免疫区，并且这种移动的预免疫受到RNA沉默的病毒抑制因子的影响。

期刊介绍： Cell Host & Microbe is a scientific journal that was launched in March 2007. The journal aims to provide a platform for scientists to exchange ideas and concepts related to the study of microbes and their interaction with host organisms at a molecular, cellular, and immune level. It publishes novel findings on a wide range of microorganisms including bacteria, fungi, parasites, and viruses. The journal focuses on the interface between the microbe and its host, whether the host is a vertebrate, invertebrate, or plant, and whether the microbe is pathogenic, non-pathogenic, or commensal. The integrated study of microbes and their interactions with each other, their host, and the cellular environment they inhabit is a unifying theme of the journal. The published work in Cell Host & Microbe is expected to be of exceptional significance within its field and also of interest to researchers in other areas. In addition to primary research articles, the journal features expert analysis, commentary, and reviews on current topics of interest in the field.
