I elements are present in many Drosophila species. It has been suggested that active, complete I elements, located at different sites on the chromosomes, invaded natural populations of D. melanogaster recently (1920-1970). But old strains lacking active I elements have only defective I elements located in the chromocenter. We have cloned I elements from D. melanogaster and the melanogaster subgroup. In D. melanogaster, the nucleotide sequences of chromocentral I elements differed from those on chromosome arms by as much as 7%. All the I elements of D. mauritiana and D. sechellia are more closely related to the chromosomal I elements of D. melanogaster than to the chromocentral I elements in any species. No sequence difference was observed in the surveyed region between two chromosomal I elements isolated from D. melanogaster and one from D. simulans. These findings strongly support the idea that the defective chromocentral I elements of D. melanogaster originated before the species diverged and the chromosomal I elements were eliminated. The chromosomal I elements reinvaded natural populations of D. melanogaster recently, and were possibly introduced from D. simulans by horizontal transmission.","is_dataset_classified":null,"base_score":2.4849066497880004,"endowment":2.4849066497880004,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"7500938","pmcid":null,"openalex_id":"https://openalex.org/W2075087776","authors":[],"funders":[],"total_grants":0,"fwci":0.5579,"citation_percentile":0.75260316,"influential_citations":1,"citation_trend":[],"oa_status":"closed","license":"http://www.springer.com/tdm","oa_locations":[{"url":"http://link.springer.com/content/pdf/10.1007/BF00290363.pdf","host_type":"publisher"},{"url":"http://link.springer.com/article/10.1007/BF00290363/fulltext.html","host_type":"publisher"},{"url":"http://link.springer.com/content/pdf/10.1007/BF00290363","host_type":"publisher"},{"url":"https://doi.org/10.1007/bf00290363","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/7500938","host_type":"repository"}],"fields_of_study":["Chromosomal and Genetic Variations","Plant Virus Research Studies","Nematode management and characterization studies","Biology","Medicine","Animals","Base Sequence","Biological Evolution","Chromosome Mapping","Cloning, Molecular","Consensus Sequence","Drosophila","Drosophila melanogaster","In Situ Hybridization","Molecular Sequence Data","Phylogeny","Restriction Mapping","Retroelements"],"mesh_terms":["Animals","Base Sequence","Chromosome Mapping","Cloning, Molecular","Drosophila","Drosophila melanogaster","Biological Evolution","Molecular Sequence Data","Phylogeny","Restriction Mapping","Consensus Sequence","In Situ Hybridization","Retroelements"],"keywords":["Melanogaster","Drosophila melanogaster","Biology","Mauritiana","Genetics","Drosophilidae","Chromosome","Retrotransposon","Drosophila (subgenus)","Evolutionary biology","Transposable element","Genome","Gene","Botany"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Life in Land"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-19T10:23:47.350935Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
