摘要
Plants use several layers of defense to detect and combat viruses(Figure 1).Specialized host-encoded receptors sense viral virulence effector proteins and induce a signal transduction cascade,leading to effector-triggered immunity(Lopez-Gomollon and Baulcombe,2022).Plants also use several RNA-based processes to seek and destroy viral RNAs.The major pathway restricting viral multiplication is RNA silencing,a widely conserved mechanism of gene extinction that uses dsRNA to produce 21 to 24 nucleotides small interfering RNAs and guide viral RNA degradation(Lopez-Gomollon and Baulcombe,2022).
