The spatial and temporal expression patterns of fifteen families of retrotransposons are analysed during embryogenesis and are found to be conserved. Results suggest that all families carry cis-acting elements that control their spatial and temporal expression patterns.
Progeny derived from wa/wa4 heterozygotes demonstrate that ectopic recombination between paired 3S18 elements produces duplications and deficiencies.
Sequences homologous to 3S18 are present about 25 times in the Drosophila genome.
A retroviral-like transposable element. Described as an insertion associated with the wa4 mutation by Goldberg et al. (FBrf0040134) (as BEL), and as an insertion within the non-transcribed spacer of an rDNA repeat by Bell et al. (FBrf0043377) and Fabijanski and Pellegrini (FBrf0038558). In situ hybridization experiments indicate that 3S18 elements are located at about twenty-five sites throughout the genome and that their distribution differs from one strain to another. The ends of this element hybridize to each other.
