| In one male cadaver of Colombian nationality, dissected by a group of medical students during a gross anatomy course at the Universidad del Valle in Cali, Colombia, three anatomical variations were found: an anomalous or aberrant right subclavian artery (ARSA), a non-recurrent inferior laryngeal nerve and a right thoracic duct. The aortic arch gave origin to four instead of three arteries, which, from right to left, were the right common carotid, the left common carotid, the left subclavian and the right subclavian arteries. The anatomical variation of the right subclavian artery is known also as lusoria artery, in which case the artery passes behind the esophagus and the trachea in its course towards the right side of the neck. The perimeters of the... |

| Background: Pigeonpea (Cajanus cajan (L.) Millsp.) is a drought tolerant legume of the Fabaceae family and the only cultivated species in the genus Cajanus. It is mainly cultivated in the semi-arid tropics of Asia and Oceania, Africa and America. In Malawi, it is grown as a source of food and income and for soil improvement in intercropping systems. However, varietal contamination due to natural outcrossing causes significant quality reduction and yield losses. In this study, 48 polymorphic SSR markers were used to assess the diversity among all pigeonpea varieties cultivated in Malawi to determine if a genetic fingerprint could be identified to distinguish the popular varieties. Results: A total of 212 alleles were observed with an average of 5.58 alleles... |

| The native European flat oyster Ostrea edulis is listed in the OSPAR Convention for the Protection of the Marine Environment of the North-East Atlantic (species and habitat protection) and in the UK Biodiversity Action Plan. Once extremely abundant in the 19th century, European stocks of O. edulis have declined during the 20th century to rare, small, localised populations due to overexploitation, habitat degradation and, most recently, the parasitic disease bonamiosis. Selective breeding programmes for resistance to bonamiosis have been initiated in France and Ireland. High genetic diversity and bonamiosis-resistance would be important features of any sustainable restoration programmes for O. edulis. Oysters were sampled across Europe from four hatchery... |

| ABSTRACT Two Coryphaena hippurus morphotypes (dourado and palombeta) are found along the Brazilian coast and are considered by Rio de Janeiro’s fisherman and fishmongers as two different species. Furthermore, these morphotypes are commercialized under different values and suffer different fishing pressure. Therefore, a definition of their taxonomic status is an important economic and biological matter. In order to investigate this problem, allozyme electrophoresis method was undertaken for seventeen loci on 117 individuals of C. hippurus sampled at Cabo Frio/RJ (Brazil). The data indicate homogeneity between the morphotypes gene pools. Nevertheless, differences were found for genetic variation among dourado and palombeta, especially due to alcohol... |

| Background Asian soybean rust (SBR) caused by Phakopsora pachyrhizi Syd. & Syd., is one of the main diseases affecting soybean and has been reported as one of the most economically important fungal pathogens worldwide. Knowledge of the genetic diversity of this fungus should be considered when developing resistance breeding strategies. We aimed to analyze the genetic diversity of P. pachyrhizi combining simple sampling with a powerful and reproducible molecular technique. Results We employed Amplified Fragment Length Polymorphism (AFLP) technique for the amplification of P. pachyrhizi DNA extracted from naturally SBR-infected plants from 23 production fields. From a total of 1919 markers obtained, 77% were polymorphic. The high percentage of... |

| Populações de açaizeiros na Amazônia são abundantes, possuem importância econômica e têm sido foco de diferentes estudos. Os açaizeiros destacam-se por produzir um importante alimento: a ?polpa de açaí?? extraída dos frutos. Nos últimos anos, a demanda pela polpa aumentou de forma expressiva por possuir características energéticas, nutritivas e altos teores de fibras e antioxidantes. A extração dos frutos é baseada no extrativismo e por isso, práticas de manejo têm sido recomendadas para uma coleta sustentável. Para se recomendar taxas sustentáveis de coleta dos frutos, é fundamental o levantamento de informações sobre a variabilidade genética das populações naturais, além do monitoramento sobre o recrutamento e a dinâmica populacional. A transferibilidade... |
