It is true that plant viruses hijack insect proteins to achieve efficient transmission

According to the latest news from the Chinese Academy of Agricultural Sciences , the Crop Virus Disease Epidemiology and Control Innovation Team of the Institute of Plant Protection of the Academy has discovered that Southern Rice Black-streaked Dwarf Virus (SRBSDV) interacts with the membrane fusion-related proteins of the White-backed Planthopper family through the viral coat protein.
It enters into the vesicles of the midgut epithelial cells and fuses to form a large vesicle, and finally breaks through the midgut cells to release a large number of virus particles to achieve efficient virus transmission
.

Team chief, China Agricultural Research Institute of Plant Protection Research Fellow Wang Xifeng reports, nearly 70 percent of the natural world spread plant viruses need to rely mediator insects like mosquitoes can spread dengue virus, the mosquito is the mediator of insects
.

The team used the southern rice black-streaked dwarf virus and the vector white backed planthopper as objects.
Electron microscopic observations found that many viruses exist in the vesicles of intestinal epithelial cells, and a large number of viruses were formed near the cell membrane on the side of the blood cavity.
Of large vesicles

This study reveals the key mechanism by which plant reovirus can overcome the midgut escape barriers of vector insects by hijacking vesicles, providing new insights into the role of vesicle transport in virus transmission and at the same time blocking the spread of viral diseases Provide candidate targets
