ABSTRACT
A gel retardation assay was used to demonstrate binding of wound tumor virus transcripts by a protein component of leafhopper vector cell extracts. Comparative binding studies employing terminally modified and internally deleted transcripts established that the segment-specific inverted repeats present in the terminal domains of the viral transcripts were necessary but not sufficient for optimal binding. An additional involvement of internal sequences in either the formation or the stabilization of the binding complex was indicated. Results of competitive binding experiments confirmed the sequence- and structure-specificity of the protein-RNA interaction and revealed apparent differences in the ability of individual viral transcripts to form a stable binding complex. Possible implications of structure-specific interactions between wound tumor virus transcripts and a host component and the role of the terminal inverted repeats are discussed.
