RESUMO
We have mapped early and late viral gene products expressed in Autographa californica nuclear polyhedrosis virus ( AcNPV )-infected Spodoptera frugiperda cells by cell-free translation of virus-specific RNA which was selected by hybridization to cloned restriction endonuclease fragments of AcNPV DNA. Proteins synthesized in vitro were labeled with [35S]methionine and analyzed by SDS-polyacrylamide gel electrophoresis followed by fluorography. At least four early AcNPV -specific polypeptides were found which mapped in two regions of the genome (9-25 and 43-59 map units). These early mRNAs are also synthesized at late times in the infection cycle. Cell-free translation of restriction fragment-selected late AcNPV -specific RNA (24 h post-infection) resulted in the identification and mapping of 24 viral proteins. Curiously, the region between approximately 70 and 80 map units on the viral genome has been found silent with respect to mRNA which is translatable in a cell-free system. However, there may be RNA transcribed from this viral DNA segment.
