miR-184-3p promotes rice black-streaked dwarf virus infection by suppressing Ken in Laodelphax striatellus (Fallén).

This study demonstrates that RBSDV infection induces the expression of miR-184-3p in its insect vector L. striatellus. miR-184-3p targets Ken to promote RBSDV accumulation and transmission. These findings provide a new insight into the function of the miRNAs in regulating plant virus infection in its insect vector.
