Jordan, an Active Volvox Transposable Element Similar to Higher Plant Transposons

We have isolated a 1595-bp transposable element from the multicellular
green alga Volvox carteri following its insertion into the nitrate
reductase (nitA) locus. This element, which we have named Jordan, has short
(12-bp) terminal inverted repeats and creates a 3-bp target site
duplication, like some higher plant transposons of the classic type.
Contained within the first 200 bp of one end of the element are 55-bp
inverted repeats, one of which begins with the terminal inverted repeat.
Revertants of the transposon insertion into the nitA locus were obtained at
a rate of ~10-4 per Volvox embryo per generation. In each revertant
examined, all transposon sequences were completely excised, but footprints
containing both sets of duplicated bases, in addition to three to nine
extra bases, were left behind. Jordan contains no significant open reading
frames and so appears to be nonautonomous. DNA gel blot analysis indicates
that Jordan is a member of a large family of homologous elements in the
Volvox genome. We have isolated and characterized several of these homologs
and found that they contain termini very similar to those of Jordan.
Efforts to utilize Jordan and its homologs as tools to tag and clone
developmentally interesting genes of Volvox are discussed.
