DNA barcode regions for differentiating Cattleya walkeriana and C. loddigesii

Made available in DSpace on 2022-04-29T23:53:04Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-01-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Universidade de São Paulo; Growers appreciate Cattleya walkeriana and C. loddigesii due to striking shape and rarity. Thus, this study aimed to evaluate the feasibility of DNA barcode regions, namely ITS1, ITS2 and rpoC1, to discrimin...

Entrelaçado, a rare maize race conserved in Southwestern Amazonia

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...

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...

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...
