Sequence comparison of tobacco TS SINE with its partner LINE. The entire sequence of the TS SINE was aligned with the 3′-end sequence (~200 nucleotides) of a potato RTE-clade LINE. Dots and hyphens represent identical nucleotides and gaps, respectively. The tRNA-related region of the SINE is underlined, with the promoter sequences for RNA pol III (A & B boxes) highlighted in red. Nucleotide positions are shown on the right.
