RESUMO

Portions of the Sendai virus genome were randomly cloned by using virion 50S RNA and calf thymus DNA pentanucleotides as primers. The recombinant clones were probed first with radiolabeled products of an in vitro virion RNA polymerase reaction to locate early message clones and then with a probe from the viral genome 3' end to locate the most 3'-proximal clones. Clones were then ordered from the 3' end of the genome and used to construct a genetic map of the 3'-proximal third of the genome by hybrid-selection of mRNAs. We report that the gene order for this region is 3'-NP - P + C - M-5' and that the genetic loci of the viral P and C proteins cannot be separated by these techniques.
