Transcripts of mobile element MDG1 during ontogenesis of Drosophila melanogaster
It has been demonstrated by Northern hybridization using a single-stranded labeled probes that the number of MDG1 transcripts as well as their size change during ontogenesis of Drosophila. The transcripts of MDG1 were not found in unfertilized eggs. The full-length transcript of MDG1 (about 7 kb long) appears in the embryonic and larval cells, and its quantity sharply increases in pupae and adults. A transcript of about 5 kb length is also found in the pupae and adults. Another, about 2 kb long transcript forms in the embryos, pupae and adults, which is absent in larvae. The main transcript in the larval cells, complementary to the inner part of the body of MDG1, is about 1 kb long. The transcription level of MDG1 and the mobile element copia do not change under heat shock at adult stage.
