POP7 and infection: To analyze the function of POP7 in the RBSDV infection progress in SBPH, POP7 was knocked down via RNA interference induced by dsPOP7, and the results showed that the decrease in POP7 expression significantly restricted the accumulation of RBSDV capsid protein (P10) at the transcript level at 4 d and protein level at 10 d after dsRNA injection compared with the control dseGFP treatment (Figure 5D,E).
