Diversidade e estrutura genética em populações de Buriti (Mauritia flexuosa L F.) com base nos marcadores moleculares AFLP

Abstract

Buriti (Mauritia flexuosa L. f.) is a palm from the Arecaceae family with a large geographic distribution all around the Amazon region and restrict to South America. It represents economic importance, having almost every part used. It is used as food and medicaments. The aim of this work was to characterize the genetic diversity of buriti s natural populatation through molecular mark AFLP. It were analyzed four population located beyond Gasoduto Coari-Manaus. For its analysis four combinations of primers were used (E-AAC/M-CAC, E-AAC/M-CGC, E-ACA/m-CGC e E-ATC/M-CCA). The primers reveled 339 focus with polymorphism, going from 81,1% to 91.1% among the population. The Fst calculated was 0.23 and the Variety Molecular Analysis s result (AMOVA) was 77,18% of varieties in populations. The reveled dendogram base on AFLP mark showed the formation of two groups, resulting that Bom Jesus and Lauro Sodré population are the most genetically alike. The result gained showed that the genetic distance are not related to the geographic distance.
