通过RNAi,植物可以识别并降解病毒RNA,从而抑制病毒侵染。同时,病毒通过编码RNA沉默抑制子(VSRs)来对抗寄主植物的RNAi防御防御手段。近年来,研究人员发现,在植物中除了RNAi以外,RNA降解(RNA decay),RNA质量控制(RQC)以及RNA N-6甲基化修饰(m6A)等机制也参与了植物抵抗病毒的防御过程。 RQC是真核生物中保守的RNA检测...

In plants, RNA interference (RNAi) or RNA silencing, which is triggered by virus‐derived double‐stranded (ds)RNA, is considered the main antiviral defence mechanism. Martínez‐Pérez et?al have now uncovered an additional plant antiviral pathway, termed by the authors "m6A‐...
RNAi has been well-established as a significant mechanism to regulate development, genome stability, stress-induced responses, and basal defense against virus invasion (Baulcombe,2004; Ding,2010; Li & Wang,2019). Plant viruses activate RNAi through double-stranded RNA (dsRNA) and viral small-inte...

Unlike the previous examples, where elevated temperatures enhance plant antiviral RNAi, an increase in temperature may conversely weaken plant defence responses to facilitate virus infection in some pathosystems (Table1) (Anfoka et al.2016; Makarova et al.2018; Obrepalska-Steplowska et al.2015; ...
Therefore, deep small (s)RNA sequencing is a universal approach for virome reconstruction and RNAi characterization. We tested this approach on dried barley leaves from field surveys. Illumina sequencing of sRNAs from 2 plant samples identified in both plants Hordeum vulgare endornavirus (HvEV) ...

Metrics Abstract Topical application of pathogen-specific double-stranded RNA (dsRNA) for virus resistance in plants represents an attractive alternative to transgenic RNA interference (RNAi). However, the instability of naked dsRNA sprayed on plants has been a major challenge towards its practical appli...
