3. Mapeamento cromossômico em espécies de Coffea L. (Rubiaceae)
O gênero Coffea L. (Rubiaceae) possui mais de 100 espécies, nativas das florestas tropicais da África e Madagascar. Coffea arabica L. é a espécie mais importante economicamente, autocompatível e a única tetraplóide do gênero com 2n = 44. As demais espécies são diplóides com 2n = 22 e autoincompatíveis.

4. Distribution of a Ty3/gypsy-like retroelement on the A and B-chromosomes of Cestrum strigilatum Ruiz & Pav. and Cestrum intermedium Sendtn. (Solanaceae)
Retroelements are a diversified fraction of eukaryotic genomes, with the Ty1/copia and Ty3/gypsy groups being very common in a large number of plant genomes. We isolated an internal segment of the Ty3/gypsy retroelement of Cestrum strigilatum (Solanaceae) using PCR amplification with degenerate primers for a conserved region of reverse transcriptase. The iso

5. Copia-, Gypsy- and Line-like Retrotransposon Fragments in the Mitochondrial Genome of Arabidopsis Thaliana
Several retrotransposon fragments are integrated in the mitochondrial genome of Arabidopsis thaliana. These insertions are derived from all three classes of nuclear retrotransposons, the Ty1/copia-, Ty3/gypsy- and non-LTR/LINE-families. Members of the Ty3/gypsy group of elements have not yet been identified in the nuclear genome of Arabidopsis. The varying d

6. Active gypsy/Ty3 retrotransposons or retroviruses in Caenorhabditis elegans.
A gypsy/Ty3-class retrotransposon (Cer1) is integrated in the DNA of Caenorhabditis elegans chromosome III. It is 8865 nt in length and has 492-nt long terminal repeats that are identical in DNA sequence. There is an exceptionally long (6819 nt) open reading frame uninterrupted by frame-shift mutations in the period since the insertion, which must therefore

7. Ten-Kilodalton Domain in Ty3 Gag3-Pol3p between PR and RT Is Dispensable for Ty3 Transposition
Ty3 is a gypsy-type, retrovirus-like element found in the budding yeast Saccharomyces cerevisiae. In cells overexpressing Ty3 under the GAL1 upstream activation sequence, Ty3 RNA, proteins, and DNA are made. Elucidation of the molecular masses and amino-terminal sequences of protease and reverse transcriptase indicated the existence of an additional interven

8. Molecular evolution of magellan, a maize Ty3/gypsy-like retrotransposon.
The magellan transposable element is responsible for a spontaneous 5.7-kb insertion in the maize wx-M allele. This element has the sequence and structural characteristics of a Ty3/gypsy-like retrotransposon. The magellan element is present in all Zea species and Tripsacum andersonii; it is absent, however, in the genomes of all other Tripsacum species analyz

9. Pyret, a Ty3/Gypsy retrotransposon in Magnaporthe grisea contains an extra domain between the nucleocapsid and protease domains
A novel Ty3/Gypsy retrotransposon, named Pyret, was identified in the plant pathogenic fungus Magnaporthe grisea (anamorph Pyricularia oryzae). Pyret-related elements were distributed in a wide range of Pyricularia isolates from various gramineous plants. The Pyret element is 7250 bp in length with a 475 bp LTR and one conceptual ORF. The ORF contains seven

10. Boudicca, a Retrovirus-Like Long Terminal Repeat Retrotransposon from the Genome of the Human Blood Fluke Schistosoma mansoni
The genome of Schistosoma mansoni contains a proviral form of a retrovirus-like long terminal repeat (LTR) retrotransposon, designated Boudicca. Sequence and structural characterization of the new mobile genetic element, which was found in bacterial artificial chromosomes prepared from S. mansoni genomic DNA, revealed the presence of three putative open read

11. Structure of the Chromosome VII Centromere Region in Neurospora crassa: Degenerate Transposons and Simple Repeats
DNA from the centromere region of linkage group (LG) VII of Neurospora crassa was cloned previously from a yeast artificial chromosome library and was found to be atypical of Neurospora DNA in both composition (AT rich) and complexity (repetitive). We have determined the DNA sequence of a small portion (∼16.1 kb) of this region and have identified a cluste

12. Sequence organization of barley centromeres
By sequencing, fingerprinting and in situ hybridization of a centromere-specific large insert clone (BAC 7), the sequence organization of centromeric DNA of barley could be elucidated. Within 23 kb, three copies of the Ty3/gypsy-like retroelement cereba were present. Two elements of ∼7 kb, arranged in tandem, include long terminal repeats (LTRs) (∼1 kb)
