Sequence characterization of coding regions of the myostatin gene (GDF8) from Brazilian Murrah buffaloes (Bubalus bubalis) and comparison with the Bos taurus sequence

Within about 30 years the Brazilian buffalo (Bubalus bubalis) herd will reach approximately 50 million head as a result of the great adaptive capacity of these animals to tropical climates, together with the good productive and reproductive potential which make these animals an important animal protein source for poor and developing countries. The myostatin gene (GDF8) is important in the physiology of stock animals because its product produces a direct effect on muscle development and consequently also on meat production. The myostatin sequence is known in several mammalian species and shows a high degree of amino acid sequence conservation, although the presence of non-silent and silent changes in the coding sequences and several alterations in the introns and untranslated regions have been identified. The objective of our work was to characterize the myostatin coding regions of B. bubalis (Murrah breed) and to compare them with the Bos taurus regions looking for variations in nucleotide and protein sequences. In this way, we were able to identify 12 variations at DNA level and five alterations on the presumed myostatin protein sequence as compared to non double-muscled bovine sequences.

Definição de requisitos de software baseada numa arquitetura de modelagem de negócios

Não é uma tarefa fácil definir requisitos para os sistemas de software que darão suporte a um negócio, dada a dinâmica de mudanças nos processos. O levantamento de requisitos tem sido feito de forma empírica, sem o apoio de métodos sistematizados que garantam o desenvolvimento baseado nos reais objetivos do negócio. A engenharia de software carece de métodos que tornem mais ordenadas e metódicas as etapas de modelagem de negócios e de levantamento de requisitos de um sistema. Neste artigo é apresentada uma metodologia de desenvolvimento de software resultante da incorporação de atividades propostas para modelagem de negócios e levantamento de requisitos, baseadas em uma arquitetura de modelagem de negócios. Essas atividades tornam o desenvolvimento de software mais sistemático e alinhado aos objetivos da organização, e podem ser incorporadas em qualquer metodologia de desenvolvimento baseada no UP (Unified Process - Processo Unificado).

Isolation and characterization of microsatellite loci from the forage species Arachis pintoi (Genus Arachis)

Arachis pintoi is an alternative to forage production in the tropics. Its germplasm comprises more than 150 accessions, that could be used to improve it. Our objective was the isolation and characterization of microsatellite loci in A. pintoi to be used to molecular evaluation of this germplasm and of A. repens (section Caulorrhizae). Seven loci were analyzed using five accessions of A. repens and 20 accessions of A. pintoi. The high variation found makes clear the high potential of this marker in genetic studies in these species. The developed markers showed total transferability to A. repens.
