ABSTRACT

Abstract Hoopoe has been traditionally treated as a single species within the order Coraciiformes. Presently, however, various authors have suggested separating the hoopoe into two or more species and even its order, Bucerotiformes. So, this work aimed to use the RAPD PCR and DNA sequences of the COI gene barcodes to confirm and to assess whether the Egyptian hoopoe is a different species named Upupa epops major from the European hoopoe called Upupa epops epops, and to determine the relationships among them. Five primers were used in this technique. Two hoopoes were taken in this work as studying birds, migratory and resident one. The results showed the highest genetic distance between them using different random primers while genetic identity was in general low, overall primers. DNA fingerprinting detected greater genetic distance between Upupa epops major and Upupa epops epops and low genetic identity, this may indicate that both hoopoes fall into two separate species. Furthermore, using mitochondrial cytochrome oxidase subunit I (COI) sequences in this study suggests the separation of Upupa epops major into a new species.

ABSTRACT

The use of donated gametes and embryos in assisted reproduction techniques (ART) makes it necessary to examine interests that involve relevant ethical and legal considerations, which include the autonomy and privacy rights of the intended parents, donors’ right to privacy and the right of the minors to know their genetic origin. This article presents arguments to consider policies of more openness to obtain information from donors in order to protect the child’s best interest in knowing his/her genetic origins. It concludes with the situation in Mexico, where ART has been carried out with donated gametes since several years ago; however, due to the absence of regulations to control these procedures, each establishment imposes its own criteria for the operation of its programs.

ABSTRACT

A seringueira [Hevea brasiliensis (Willd. ex. Adr. de Juss) Muell.-Arg.] é uma espécie nativa da região amazônica e compreende a maior fonte produtora de borracha natural do mundo. Na busca de condições mais favoráveis ao cultivo, além da busca pela auto-suficiência na produção de borracha natural, o cultivo da seringueira migrou para outras regiões do país. Objetivou-se, com o presente trabalho, estimar a similaridade genética de genótipos de seringueira, provenientes de regiões distintas do país, Lavras-MG (UFLA) e Campinas-SP (IAC), por meio de marcadores moleculares RAPD. A análise foi efetuada em 41 indivíduos, representados por 17 genótipos diferentes, com base em 19 primers, que geraram 121 fragmentos polimórficos. Os dados foram analisados utilizando o software NTSYS-pc - 2.1, por meio do coeficiente de Dice e pelo método das médias (UPGMA). A similaridade genética entre o material analisado variou de 0,56 a 1,00. Na análise do dendrograma, foram observados 18 grupos. Os clones (RRIM600, GT1, PB235, PL PIM e FX2261), utilizados em diferentes repetições, foram idênticos, quando comparados entre si, entretanto o mesmo não foi observado para os clones identificados como RRIM 701. Os resultados obtidos sugerem que o material avaliado na UFLA é o mesmo implantado no IAC, exceto o RRIM 701, mostrando uma ampla variabilidade genética, disponível para estudos e propagação da cultura.


The rubber tree [Hevea brasiliensis (Willd. ex. Adr. de Juss) Muell.-Arg.] is a native species from Amazon region, and represents the biggest source of natural rubber in the world.. However, the rubber tree culture has had an expansion to other brazilian regions, in search of more favorable conditions for its cultivation and self-sufficiency in natural rubber. The aim of this work was to estimate genetic similarity among rubber tree clones, from different Brazilian regions, Lavras (UFLA) and Campinas (IAC), by using RAPD molecular markers. The analysis was made using 41 individual plants, which represent 17 different clones, based on 19 primers, which raised 121 polymorphic fragments. The data were analysed with NTSYS-pc - 2.1 software, by using Dice coefficient and UPGMA method. Genetic similarity among the materials showed variation from 0,56 to 1,00. In dendogram analysis, 18 groups were observed. The clones RRIM600, GT1, PB235, PLPIM and FX2261 used in different replications, were identical, when compared among themselves. However, results were not the same for the clones identified by RRIM 701. Results suggest that the UFLA material is the same of IAC material, except for RRIM 701, showing wide genetic variability available for studies and culture propagation.
