Nuclear localization of actin requires AC102 in Autographa californica multiple nucleopolyhedrovirus-infected cells.

Autographa californica multiple nucleopolyhedrovirus requires nuclear actin for progeny virus production and thereby encodes viral products that ensure actin's translocation to and retention within the nucleus. Current evidence suggests that the ie0-ie1 gene complex along with five nuclear localization of actin (NLA) genes are sufficient for NLA in transient transfection experiments. Here we report that, during infection, only one of the five NLA genes, Ac102, was essential for NLA, and that AC102 had at least one other activity critical for budded virus (BV) production.

Binding of virus-like particles of Norwalk virus to romaine lettuce veins.

Noroviruses (NoV) annually cause millions of cases of gastrointestinal disease in the United States. NoV are associated with raw shellfish outbreaks, particularly oysters, which are thought to bioaccumulate NoV particles during the filter-feeding process. NoV outbreaks, however, have also been known to occur from other common-source food-borne vehicles, such as lettuce, frozen raspberries, and salad.
