Hantaan virus (HTNV) is an Old World hantavirus associated with hemorrhagic fever with renal syndrome (HFRS). To visualize the localization of the L protein of HTNV strain 84FLi within cells, a fusion protein composed of enhanced green fluorescent protein and L protein, EGFP-L, was expressed in Vero cells. The 273 KDa expressed fusion protein of EGFP-L localized in the perinuclear region. We also described the development of a reverse genetics system for HTNV strain 84FLi. The RNA polymerase I (pol I)-mediated transcription system was used to generate artificial viral RNA genome segments (minigenomes), which contained the chloramphenicol acetyltransferase (CAT) reporter gene in antisense (virus RNA) or sense (virus-complementary RNA) orientation flanked by the noncoding regions of HTNV 84FLi L segment. CAT could be detected in cells after transfection, indicating the successful encapsidation, transcription and replication of the pol I-derived minigenomes. The passaged transfer of CAT demonstrates that recombinant virus containing packaged pol I-derived minigenomes has been produced. This system may be helpful in studying the gene function and pathogenesis of HTNV.
