    Notes: Abstract Phylogenetic analysis of five partial planktic foraminiferal small subunit (SSU) ribosomal (r) DNA sequences with representatives of a diverse range of eukaryote, archaebacterial, and eubacterial taxa has revealed that the evolutionary origin of the foraminiferal lineage precedes the rapid eukaryote diversification represented by the “crown” of the eukaryotic tree and probably represents one of the earliest splits among extant free-living aerobic eukaryotes. The foraminiferal rDNA sequences could be clearly separated from known symbionts, commensals, and food organisms. All five species formed a single monophyletic group distinguished from the “crown” group by unique foraminiferal specific insertions as well as considerable nucleotide distance in aligned regions.

    Instability in the ct MR2 strain of Drosophila melanogaster: Role of P element functions and structure of revertants (1989)

    Notes: Summary Simultaneous multiple transpositions and longterm genetic instability have been described in the ct MR2 strain of Drosophila melanogaster and its derivatives. This strain originated from a cross that was dysgenic in the P-M system. While spontaneous instability declined over 2 years, instability has been reactivated by backcross to the progenitor P element bearing strain MRh12/Cy. We show here using germline transformation that active P factor alone cannot mimic the effect of this cross, suggesting that MRh12/Cy contains some other activator. In addition, we have observed that ct + exceptional progeny arise in the F1 s well as the F2 generations. Molecular analysis of X chromosomes from some ct + progeny indicates that phenotypic reversion of the ct mutation can arise through two unrelated mechanisms.
