title: In vitro RNA transcription by the New Jersey serotype of vesicular stomatitis virus. II. Characterization of the leader RNA.
abstract: The New Jersey serotype of vesicular stomatitis virus (VSV) was able to synthesize a small RNA (leader RNA) approximately 70 bases in length similar to the leader RNA synthesized in vitro by the genetically distinct Indiana serotype of VSV. Also, the New Jersey leader RNA contained the same 5'-terminal sequence, ppA-C-G, as the Indiana leader RNA and had a very similar base composition, with 42% AMP, 16% CMP, 18.6% GMP, and 23.4% UMP. The 3'-terminal sequence of the VSV New Jersey genome RNA was detemined and found to contain the sequence- Py-G-UOH, again the same as that of the Indiana serotype of VSV. Evidence that the New Jersey leader RNA is transcribed from the 3' end of the genome RNA was obtained from the fact that it can protect the 3'-terminal base of [3H]borohydride-labeled New Jersey genome RNA from RNase digestion. Although the New Jersey and Indiana leader RNAs were similar in many respects, they were unable to form RNase-resistant hybrids when annealed to heterologous genome RNA.
