A population genomics appraisal suggests independent dispersals for bitter and ...

Amazonia is a major world centre of plant domestication, but the genetics of domestication remains unclear for most Amazonian crops. Manioc (Manihot esculenta) is the most important staple food crop that originated in this region. Although manioc is relatively well-studied, little is known about the diversification of bitter and sweet landraces and how they were dispersed across Amazonia. We evaluated single nu...

Distribution and Growth of Garcinia brasiliensis Mart. and Hevea spruceana (Ben...

This study assessed the distribution and growth of two tree species in a seasonal mixed-water inundation forest near the city of Manaus, and determined the annual growth rates and ages of trees. The aboveground wood biomass was estimated for each population. Eight plots of 25 × 25 m were established, where all individuals of the species Garcinia brasiliensis and Hevea spruceana with heights ≥ 1.0 m were invento...

Highly structured genetic diversity of Bixa orellana var. urucurana, the wild a...

Annatto (Bixa orellana L.) is a tropical American crop, commercially valuable due to its application in the food and cosmetics industries as a natural dye. The wild ancestor of cultivated annatto is B. orellana var. urucurana. Although never cultivated, this variety occurs in open forests and anthropogenic landscapes, and is always associated with riparian environments. In this study, we evaluated the genetic d...

Genetic diversity and structure of astrocaryum jauari (mart.) palm in two amazo...

Astrocaryum jauari is a non-domesticated palm that is exploited by poachers. Our objective was to investigate the organization of the genetic diversity and structure of three A. jauari populations. The study was carried out in the state of Amazonas, between the municipalities of Coari and Manaus. Nine microsatellite loci were used for the genetic analyses. High genetic variation was found, with a mean number of...

New microsatellite loci for annatto (Bixa orellana), a source of natural dyes f...

Annatto (Bixa orellana) is a tropical crop native to the Americas with Amazonia as the likely center of origin of domestication. Annatto is important because it produces the dye bixin, which is widely used in the pharmaceutical, food, cosmetic and textile industries. A total of 32 microsatellite loci were isolated from a microsatellite-enriched genomic library, of which 12 polymorphic loci were used to characte...

Determination of the mating system of Tucumã palm using microsatellite markers

Patterns of nuclear and chloroplast genetic diversity and structure of manioc a...

Background and Aims Amazonia is a major world centre of plant domestication, but little is known about how the crops were dispersed across the region. Manioc (Manihot esculenta) was domesticated in the south-western Amazon basin, and is the most important staple food crop that originated in Amazonia. Current contrasting distributions may reflect distinct histories of dispersal of bitter and sweet manioc landrac...

Explant type and different concentrations of salts in MS medium in vitro establ...

The peel - precious ( Aniba canelilla ) is a plant species native to the Amazon region , with economic potential in silvicultural terms , the production of perfumes and cosmetics . However , one limitation to the domestication of the species is the absence of propagation methods . The objective of this study was to evaluate the effect of explant type and different salt concentrations of MS medium in their estab...
