Abstract:

Summary

The process by which Ectocarpus fasciculatus virus type 1 (EfasV-1) infects zoospores of its brown algal host was studied by electron microscopy. Upon virus attachment to the target cell, the integral membrane component of the viral capsid fuses with the host plasma membrane, and the 140-nm viral DNA-protein core enters the cytosol. Within 5 min after infection, particles resembling viral cores appeared in the nucleus. The entry mechanism of EfasV-1 into the host nucleus remains enigmatic.
