[i] (N.D.) Not determined

[ii] (frag.) These elements have a PBS complementary to an internal region of the primer tRNA, starting in the anticodon stem, 2 bp from the anticodon loop.

[iii] Length of the composite elements are given in base pairs.

[iv] (Intact) Long ORFs present containing all of the motifs characteristic of full-length, functional retrotransposons; (partial) long ORFs are present but no full-length ones discovered yet; (frag.s) no long ORFs, but short regions of homology to other retroelement ORFs are present; (no) no long ORFs present nor any homology to other retroelements in databases.

[v] In some cases, these assignments are tentative and based solely on the forms of the PBS or their positions relative to the LTRs.

[vi] The internal region of Tca10 does contain ORFs, but they show no similarity to any known retrotransposon ORFs.
