Genetic diversity of Bertholletia excelsa, an Amazonian species of wide distribution
Background Amazonian upland forests are expansive and can comprise large continuous tracts. There have been several studies on the population genetic structure of species in this kind of forest, but there are few studies that aim to understand genetic structure throughout the Amazon [1]. The Brazil-nut tree, Bertholletia excelsa, is a monotypic genus, endemic to upland forests and distributed a...
متن کاملContemporary pollen and seed dispersal in natural populations of Bertholletia excelsa (Bonpl.).
Due to the nutritional content and commercial value of its seeds, Bertholletia excelsa is one of the most important species exploited in the Amazon region. The species is hermaphroditic, insect pollinated, and its seeds are dispersed by barochory and animals. Because the fruit set is dependent on natural pollinator activity, gene flow plays a key role in fruit production. However, to date, ther...
متن کاملDiversity and genetic structure of the native Brazil nut tree (Bertholletia excelsa Bonpl.) population.
The present study was carried out in a native Brazil nut tree population (Bertholletia excelsa Bonpl., Lecythidaceae) to assess its genetic diversity and structure. Ten microsatellite markers were used to genotype 198 adult trees (B. excelsa). The population presented high genetic diversity and inbreeding absence rates. The empirical Bayesian method showed three distinct groups in the structure...
متن کاملConstruction of Brazil nut (Bertholletia excelsa: Lecythidaceae) cambium normalized cDNA libraries for 454 next generation sequencing
Background The Brazil nut, Bertholletia excelsa (Lecythidaceae), is the most important non-timber forest resource in the Amazonian biome, where nuts for the international trade are exclusively wild-collected. The monotypic genus possesses a discontinuous distribution and is thought to have rapidly and recently radiated south and westward from a northern/eastern Amazonian origin, largely as a re...
متن کاملDetailed Study of Brazil Nut ( Bertholletia excelsa ) Oil Micro - Compounds : Phospholipids , Tocopherols and Sterols
O óleo da castanha-do-pará (Bertholletia excelsa) foi estudado por causa da sua composição em ácidos graxos, tocoferóis, esteróis e fosfolipídios. A composição de ácidos graxos nos fosfolipídeos também foi estudada. Os resultados foram comparados com os do girassol, da castanha, amêndoa, noz, soja e azeites. O seu alto teor em ácidos graxos insaturados, em b-tocoferol e em b-sitosterol confere ...
