Envelope fusion protein GP64 accumulated substantially in vHycuBac/hcf-1-infected Tn368 cells from 24 h post-infection onwards (Fig. 4d) and VP39 and polyhedrin proteins were clearly detected at 48 h post-infection and remained detectable at 72 h post-infection in vHycuBac/hcf-1-infected Tn368 cells (Fig. 4d). The gene discussed is HCFC1; the disease is infection.
