title: Reverse transcriptase families and a copia-like retrotransposon, Osser, in the green alga Volvox carteri.
abstract: By using the polymerase chain reaction (PCR) we have isolated and sequenced two distinct families of reverse transcriptase (RT) sequences from the genome of the colonial alga, Volvox carteri. Probing a genomic library with these RT clones revealed copia-like retrotransposons. One of these elements, named Osser, is 4,875 bp long, bordered by 197-bp identical long terminal repeats (LTRs), and shows the typical organization of retrotransposons belonging to the copia-Tyl group. This is the first complete copia-like retrotransposon sequence described in a green alga.
