13. The promoter of a gene encoding an isoflavon reductase-like protein in coffee (Coffea arabica) drives a stress-responsive expression in leaves.
A cDNA clone (designated CaIRL) encoding an isoflavone reductase-like protein from coffee (Coffea arabica) was retrieved during a search for genes showing organ/tissue-specific expression among the expressed sequence tags (EST) of the Brazilian coffee EST database. The CaIRL cDNA contains a single open reading frame of 946 nucleotides (nt) encoding 314 amino

15. Análise do complexo gênico FANCD2/FANCI em mulheres brasileiras com câncer de mama herediitário / Analysis of the gene complex FANCD2/FANCI in Brazilian womem with hereditary breast cancer
O câncer de mama (CM) é o tipo de câncer que mais comumente ocorre entre mulheres, com a estimativa de 49.240 novos casos diagnosticados em 2010 no Brasil. O CM apresenta fatores de risco conhecidos como idade, fatores sócio-econômicos, etnia, exposição excessiva a hormônios, radiação, dieta, exercícios físicos, história ginecológica e históri

16. Identificação de novas possíveis variantes do Infectious Bursal Disease Virus (IBDV) / Identification of possible new variants of Infectious Bursal Disease Vírus (IBDV)
The Brazilian poultry industry is the worlds leading exporter of chickens meat. One of main agents causing losses is the virus of infectious bursal disease-IBDV, belonging to the family Birnaviridae.There are two serotypes of IBDV: serotypes 1 and 2, and all the viruses able to cause disease in birds belong to serotype 1. In Brazil, the virus has been respon

17. CA88, a nuclear repetitive DNA sequence identified in Schistosoma mansoni, aids in the genotyping of nine Schistosoma species of medical and veterinary importance
CA88 is the first long nuclear repetitive DNA sequence identified in the blood fluke, Schistosoma mansoni. The assembled S. mansoni sequence, which contains the CA88 repeat, has 8,887 nucleotides and at least three repeat units of approximately 360 bp. In addition, CA88 also possesses an internal CA microsatellite, identified as SmBr18. Both PCR and BLAST an

18. Phylogenetic analysis of Biomphalaria tenagophila (Orbigny, 1835) (Mollusca: Gastropoda)
Mitochondrial DNA of Biomphalaria tenagophila, a mollusc intermediate host of Schistosoma mansoni in Brazil, was sequenced and characterised. The genome size found for B. tenagophila was 13,722 bp and contained 13 messenger RNAs, 22 transfer RNAs (tRNA) and two ribosomal RNAs (rRNA). In addition to sequencing, the mitochondrial DNA (mtDNA) genome organizatio

19. Molecular characterization of beta-tubulin from Phakopsora pachyrhizi, the causal agent of Asian soybean rust
β-tubulins are structural components of microtubules and the targets of benzimidazole fungicides used to control many diseases of agricultural importance. Intron polymorphisms in the intron-rich genes of these proteins have been used in phylogeographic investigations of phytopathogenic fungi. In this work, we sequenced 2764 nucleotides of the β-tubulin gen

20. Mitochondrial control region genetic diversity and maternal ancestry of a Brangus-Ibage cattle populations
The genetic diversity of 277 nucleotides in the mitochondrial DNA control region (nt 15,964 to 16,240 in reference sequence) was analyzed in crossbreed beef cattle (Brangus-Ibage, 5/8 Bos primigenius taurus x 3/8 Bos primigenius indicus) as well as in some Nellore samples (B. p. indicus). Fifty-seven mutations were found in Brangus-Ibage comprising 18 haplot

21. Unravelling MADS-box gene family in Eucalyptus spp. : a starting point to an understanding of their developmental role in trees
MADS-box genes encode a family of transcription factors which control diverse developmental processes in flowering plants ranging from root to flower and fruit development. Members of the MADS-box gene family share a highly conserved sequence of approximately 180 nucleotides that encodes a DNA-binding domain. We used bioinformatics tools to investigate the i

22. Modelo de sistema de comunicações digital para o mecanismo de importação de proteinas mitocondriais atraves de codigos corretores de erros / Digital communication system model for mitochondrial protein import by use of error-correcting codes
One of the puzzling problems in mathematical biology is to show the existence of any form of error-correcting code in the DNA structure. Using information theory considerations we propose a model for the biological coding system similar to that of a digital communication system. This model consists of a mapper (transformations from the set of nucleotides eit

23. Aspectos de física estatística na evolução e no crescimento molecular. / Aspects of statistical physics on evolution and in molecular growth.
Molecular Evolution, stimulated and supported by Evolution Synthetic Theory, became essential to understand evolution of life. Genomic growth was responsible to increase the capacity of storage information and to stability of the molecule; besides, it was also submitted to natural selection. Using amplification-mutation-selection methodology, such as SELEX (

24. Variabilidade genética da Dourada na Bacia do Rio Branco
Dourada is one of the largest catfishes exploited in the Amazon region. Five countries exploit this resource, which is considered, by several authors, as a unique population with seasonal migration, occurring in the whole basin, using distinct areas for reproduction, feeding and growth. Ecological or genetic data about this specie in Roraima are unknown. The
