    Evidence for retrotranscription of protein-coding genes in the Drosophila subobscura genome (1992)
    Springer
    Journal of molecular evolution 35 (1992), S. 492-501

    Notes: Summary Evidence is provided for the presence of retrosequences (also named retroposons) arising from Adh in the Drosophila subobscura genome. Restriction analysis and primary structure of two different retrosequence-containing clones, S812 and S135, are reported. The fact that these retrosequences lack introns and a recognizable promoter strongly supports their retrotranscriptional origin. Adjacent to the two retrosequences analyzed, a middle repetitive DNA element has been found which bears no clear similarity to any sequence reported to date in the GenBank/EMBL Data Library. A comparative analysis of these retrosequences with the functional Adh gene of D. subobscura is presented. In addition, a model concerning the origin, functionality, and propagation of these genome elements is discussed.

    Latitudinal differences in sex chromosome inversions, sex linked allozymes, and mitochondrial DNA variation in Drosophila subobscura (1993)
    Springer
    Genetica 92 (1993), S. 67-74 
    Details
    ISSN: 1573-6857
    Keywords: Drosophila subobscura ; clines ; gene arrangements ; allozymes ; mitochondrial DNA ; gametic association ; cytonuclear association

    Topics: Biology
    Notes: Abstract Mitochondrial DNA, sex linked allozymes, and chromosome A gene arrangement data, from eight European natural populations of Drosophila subobscura, were analyzed to determine the existence of latitudinal clines. Strong north-south correlations with latitude were found for gene arrangements and for the Hbdh and 6Pgdh allozymes. Gametic associations between the A2 gene arrangement, the Hbdh 96 and the 6Pgdh 96 alleles, point out some kind of epistatic interaction. At mtDNA level, the Hae III, A variant did not show a previously found north-south clinal variation.
