Comments
	Used in an investigation to address the relationship between retrotransposons and retroviruses and the coadaptation of these retroelements to their host genomes. Results indicate retrotransposons are heterogeneous in contrast to retroviruses, suggesting different modes of evolution by slippage-like mechanisms. (Terzian et al., 1997) The nucleotide sequence of Dsub\gypsy is determined. A comparative analysis of the sequence and molecular structures of Dsub\gypsy, Dvir\gypsy and gypsy reveals gypsy is the only infectious particle, the other two have lost the ability. (Alberola and de Frutos, 1996) Dsub\gypsy, Dvir\gypsy and gypsy show many structural similarities including sequences necessary for transcription and regulatory and coding sequences which suggest a common mechanism of expression. The ORF3 of Dsub\gypsy and Dvir\gypsy lack some motifs essential for the function of the "env-like" protein. (Alberola and de Frutos, 1995) Comparisons between gypsy sequences in D.melanogaster, D.subobscura and D.virilis strongly suggest that gypsy sequences have been horizontally transferred between these species. (Alberola and de Frutos, 1993) gypsy and Dvir\gypsy virus-like particles (VLP) are present in the cultured media from D.melanogaster and D.virilis. (Syomin et al., 1993) A Dvir\gypsy element has been cloned and sequenced, and compared with D.melanogaster gypsy. (Mizrokhi and Mazo, 1991) Isolated from a D.virilis genomic library, using probes corresponding to the first and third open reading frames and long terminal repeat of D.melanogaster gypsy. (Mizrokhi and Mazo, 1991)
