  • Title: Tomato spotted wilt virus S-segment mRNAs have overlapping 3'-ends containing a predicted stem-loop structure and conserved sequence motif.
    Author: van Knippenberg I, Goldbach R, Kormelink R.
    Journal: Virus Res; 2005 Jun; 110(1-2):125-31. PubMed ID: 15845263.
    Abstract:
    The Tomato spotted wilt virus ambisense M- and S-RNA segments contain an A/U-rich intergenic region predicted to form a stable hairpin structure. The site of transcription termination of S-segment encoded N and NSs mRNAs synthesised in an in vitro transcription system was roughly mapped to the 3'-end of the intergenic hairpin, i.e. position 1568-1574 for N and position 1852-1839 for NSs, as determined by RT-PCR cloning and size estimation on Northern blots. This suggests that these viral transcripts contain a predicted stem-loop structure at their 3'-end. The potential involvement of the 3'-end structure in transcription termination is discussed.
