Pinus taeda BAC12 (clone Pt314B2) illustrates several new trends found in the pine genome. (A) The length of BAC12 is shown along the horizontal axis. Shown above the axis are tracks of annotated genes (dicot and monocot parameters), similarity hits to Repbase [RM (blastx); DNA transposons; Non-LTR retroelements; ERV (endogenous retroviruses); LTR retroelements, copia; LTR retroelements, gypsy], and other elements identified in this study (simple repeats, tandem repeats, ORF elements, pairs of direct repeats, and regions of similarity among BACs). The bottom two tracks indicate WGS coverage at ≥ 75% identity and at ≥ 99% identity (B) Genes were annotated with both dicot and monocot parameters. The annotations generally differed in gene structure. (C) Coverage is similar between coverage tracks for active and relatively abundant retroelements in the pine genome such as this nested PtIFG7.
