Última Distribution and conservation of the transposable element gypsy in drosophilid species Genet. Mol. Biol. Herédia,Fabiana; Loreto,Elgion Lúcio S.; Valente,Vera Lúcia S.. In an attempt to understand the dynamics of transposable elements (T'S) in the genome of host species, we investigated the distribution, representativeness and conservation of DNA sequences homologous to the Drosophila melanogaster gypsy retrotransposon in 42 drosophilid species. Our results extended the knowledge about the wide distribution of gypsy in the genus Drosophila, including several Neotropical species not previously studied. The gypsy-like sequences showed high divergence compared to the D. melanogaster gypsy element. Furthermore, the conservation of the restriction sites between gypsy sequences from phylogenetically unrelated species pointed to a more complex evolutionary picture, which includes the possibility of the horizontal transfer events...

Mol. Biol. Utsunomia,Ricardo; Pansonato-Alves,José Carlos; Scacchetti,Priscilla Cardim; Oliveira,Claudio; Foresti,Fausto. The fish species Synbranchus marmoratus is widely distributed throughout the Neotropical region and exhibits a significant karyotype differentiation. However, data concerning the organization and location of the repetitive DNA sequences in the genomes of these karyomorphs are still lacking. In this study we made a physical mapping of the H3 and H4 histone multigene family and the transposable elements Rex1 and Rex3 in the genome of three known S. marmoratus karyomorphs. The results indicated that both histone sequences seem to be linked with one another and are scattered all over the chromosomes of the complement, with a little compartmentalization in one acrocentric pair, which is different from observations in other fish groups. Likewise, the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Synbranchidae; FISH; Histone; Retrotransposon.

Mol. Biol. Wang,Yi-Hong; Warren Jr.,James T.. Retrotransposons (RTEs) are a principal component of most eukaryotic genomes, representing 50%-80% of some grass genomes. RTE sequences have been shown to be preferentially present in disease resistance gene clusters in plants. Arabidopsis thaliana has over 1,600 annotated RTE sequences and 56 of these appear to be expressed because of the exact expressed sequence tag (EST) matches and the presence of intact open reading frames. Of the 22 represented in the Affymetrix ATH1 array, AtCOPIA4 was found to be expressed at a higher level than all other RTEs across different developmental stages. Since AtCOPIA4 is located in the RPP5 gene cluster and is adjacent to RPP4 which confers resistance to the downy mildew oomycete Hyaloperonospora parasitica isolate...
