Structural features of the C. quinquefasciatus LTR-retrotransposons detected.

“Lineage” indicates the major lineage they belong to; the estimated copy number detected by BLAST analysis is indicated in the column “copies”; copies enumerated in column “Elements” are those identified by the LTR_STRUC program; “length” indicates the overall element length; “ORFs” indicates the number of ORFs detected in each element; TSD shows the target sequence duplicated upon insertion, Primer Binding Site (PBS); LTR indicates the LTR length; supercontig indicates the supercontig where a given element was identified. %LNI: percent LTRs nucleotide identity.Note that two values are reported in the LTRs column if the two LTRs of an element differ in size. “frag” indicates fragmented coding regions.
