Publikováno v: Memorias do Instituto Oswaldo Cruz, Vol 92, Iss 3, p 333 (1997)

Here we review the phenomenon of persistency in Leishmania (Viannia) braziliensis infections. In other Leishmania species where appropriate animal models exist, considerable advances in the understanding of basic immunologic mechanisms of persistency

The control of gene expression in the human parasite Leishmania occurs mainly at the post-transcriptional level. Nevertheless, basic cell processes such as ribosome biogenesis seem to be conserved. Mature ribosomal RNAs (rRNAs) are synthesized from t

Saccharomyces cerevisiae RNA Polymerase I Terminates Transcription at the Reb1 Terminator In Vivo

Autor: Judith G. Roan, Ronald H. Reeder, Palmira Guevara

Publikováno v: Molecular and Cellular Biology. 19:7369-7376

We have mapped transcription termination sites for RNA polymerase I in the yeast Saccharomyces cerevisiae. S1 nuclease mapping shows that the primary terminator is the Reb1p terminator located at +93 downstream of the 3′ end of 25S rRNA. Reverse tr

Publikováno v: Plant Molecular Biology Reporter. 13:182-191

Somaclonal variants resistant to sugarcane mosaic virus (SCMV) were obtained from susceptible sugarcane cv PR62258 through somatic embryogenesis by increasing the number of subcultures of the embryogenic callus tissue in MS medium with 3 mg/L 2,4-dic

Memórias do Instituto Oswaldo Cruz, Volume: 87, Issue: 4, Pages: 517-523, Published: DEC 1992

A study of Trypanosomatidae GC distribution and codon usage is presented. The codon usage patterns in coincidence with the phylogenetical data are similar in Crithidia and Leishmania, whereas they are more divergent in Trypanosoma brucei and T. cruzi
