dc.description.abstractThe objective of this work was to determine the geographic origin of the Madeiran common bean (Phaseolus vulgaris) gene pool. Phaseolin patterns of 50 accessions representing the diversity of common bean collected in Madeira, Portugal, and conserved in the ISOPlexis Germplasm Bank, were analysed using the Experion automated electrophoresis system, based on lab-on-a-chip technology. Five common bean standard varieties with typical phaseolin patterns were used to determine the phytogeographical origin of the Madeiran common bean accessions. Ninety two percent of the accessions exhibited a phaseolin pattern consistent with the one of common bean types belonging to the Andean gene pool, while the origin of the remaining 8% of the accessions was indistinguishable. The application of a similarity coefficient of 85%, based on Pearson correlations, increases the number of accessions with uncertain pattern. The analytical approach used permitted the determination of the origin of the common bean gene pool, which is Andean in 98% of the cases, and clustering of the observed variability among the Madeiran common beans.pt_PT
dc.description.abstractO objetivo deste trabalho foi determinar a origem geográfica do “pool” genético do feijoeiro‑comum (Phaseolus vulgaris) da ilha da Madeira, Portugal. Os perfis de faseolinas de 50 acessos que representam a diversidade do feijoeiro-comum coletados na ilha da Madeira, conservados no banco de germoplasma ISOPlexis, foram analisados por meio do sistema de eletroforese automática Experion, baseado na tecnologia “lab‑on‑a‑chip”. Cinco variedades padrão de feijoeiro, com perfis típicos de faseolina, foram usadas para determinar a origem fitogeográfica dos acessos de feijoeiro-comum da ilha da Madeira. Noventa e dois por cento dos acessos exibiram um perfil consistente com o dos tipos pertencentes ao “pool” genético Andino, enquanto não foi possível determinar a origem de 8% dos acessos restantes. A aplicação de um coeficiente de similaridade de 85%, com base em correlações de Pearson, aumentou o número de acessos com perfil incerto. A abordagem analítica utilizada permitiu determinar a origem andina do “pool” genético em 98% dos casos, e o agrupamento da variabilidade observada entre os feijões da Madeira.pt_PT
