Embodiment 1

[0039] Embodiment 1, the research on the relationship between RSV and the JNK signaling pathway of vector insects

[0040] The inventors of the present invention have carried out in-depth research on how RSV affects the signal pathway of vector insects, especially the influence of the interaction between CP and GPS2 on the JNK signal pathway of vector insects. Because viruses are intracellular parasites, it is reasonable to speculate that viral proteins regulate host cell signaling pathways. In a compatible virus-host relationship, whether virus-regulated cellular signaling pathways such as vector insects and hosts benefit viruses in replication and dissemination is unknown. In this study, the results of the present invention show that RSV regulates the JNK signaling pathway to increase viral replication. By regulating several important genes passed by JNK and inhibiting the activation of JNK pathway, the spread of RSV virus can be effectively controlled.

Abstract

The invention discloses a method of controlling rice stripe virus propagation. The method of controlling rice stripe virus propagation concretely includes the following step that rice stripe virus propagation is controlled by inhibiting activation of the JNK signal channel of rice stripe virus amboceptor insects. The result displays RSV regulation and regulates the JNK signal channel to increase virus copy. Activation of the JNK channel is inhibited by regulating several important genes of the JNK channel, and RSV virus propagation can be effectively controlled. A new strategy is provided for prevention and control of plant RSV viruses.

Description

technical field [0001] The invention belongs to the field of plant virus prevention and control, and relates to a method for controlling the spread of rice stripe virus, in particular to a method for controlling the spread of rice stripe virus by inhibiting the JNK signal pathway of vector insects. Background technique [0002] Plant viruses are pathogenic agents of a wide variety of agricultural and non-cultivated crops. Spatial distance is the primary limiting factor for the spread of plant viruses, but vector insects, especially piercing-sucking insects, are vectors for viruses to overcome this obstacle, such as planthoppers, aphids, white lice, leafhoppers, pasture insects, and psyllids and water wax worms, etc. [0003] There are four modes of virus transmission in vector insects: non-persistent, semi-persistent, persistent circulation and persistent multiplication. Among them, the transmission mode of levovirus, tomato spotted wilt virus, rhabdovirus, maize thread vi...
