title: Bmmar6, a second mori subfamily mariner transposon from the silkworm moth Bombyx mori.
abstract: A second member of the divergent mori subfamily of mariner transposons, Bmmar6, is described from the silkworm moth Bombyx mori genome. A confident consensus sequence for Bmmar6 was obtained from a single genomic copy, 17 EST sequences, and the direct sequencing of a 'family' sequence from an amplification of all full-length genomic copies. Bmmar6 is most similar to Bmmar1 in the mori subfamily, which now also includes several fly and nematode transposons. These might be viewed as a discrete family of transposons within the IS630-Tc1-mariner superfamily with a distinctive D,D37D catalytic motif, and another small divergent D,D41D clade is recognized as their sister group of transposons.
