A Novel Family of Terminal-Repeat Retrotransposon in Miniature (TRIM) in the Genome of the Red Harvester Ant, Pogonomyrmex barbatus
Figure 6
Examples of PbTRIM elements and solo-LTRs located within or near genes.
Exons of predicted genes are shown as red boxes, with the last exons denoted as pentagons to indicate the transcription orientation. The solid and the dashed lines represent gene introns and intergenic regions, respectively. The direction of the LTR sequences is indicated by the grey triangles in the open square, and the TSD sequences are shown on the either side of the element or solo-LTR. (A) A complete PbTRIM element is located within 1-kb from the transcription start sites of two genes (upstream: protein SERAC1, downstream: GTP-binding protein ypt7). (B) A complete element contributes sequence to the second exon-intron boundary of the gene encoding SET and MYND domain-containing protein 4. (C) A solo-LTR is located within the first intron of a gene encoding the focal adhesion kinase 1.
