CP and infection: Time-course experiments allowed us to establish the temporal sequence of the stages of CP localization: as shown in Figure 2, CP-GFP progresses through stages I–II–III–IV–V in individual cells (Figure 2A), and different stages coexist in the cell population (Figure 2B); the overall progression of stages correlates with viral DNA accumulation (Figure 2C), suggesting that it occurs as part of or in parallel to the development of the infection.
