ABSTRACT Introduction Characterized as relatively isolated communities, many Brazilian quilombos were formed during the period of slavery in Brazil when enslaved persons (most of African descent) ran away or were abandoned by their enslavers. Quilombos in Central Brazil, whose settlement was more recent due to the relative isolation of the region ...

Pedigree Analysis of Modern Muscadine Cultivars Reveals a Narrow Genetic Base
Muscadine grape (Vitis rotundifolia var. rotundifolia) is a rare crop in that it has transitioned from a wild fruiting plant to a domesticated fruit within the past 150 years.

Estimation of coancestry in Iberian pigs using molecular markers
Genetic markers provide a useful tool to estimate pairwise coancestry between individuals in the absence of a known pedigree. In the present work 62 pigs from two related strains of Iberian breed, Guadyerbas and Torbiscal, belonging to a conservation programme with completely known pedigrees since 1945, have been genotyped for 49 microsatellites.

Advantages of using molecular coancestry in the removal of introgressed genetic material [PDF]
When introgression of undesired exogenous genetic material occurs in a population intended to remain pure, actions are necessary to recover the original background. It has been shown that genome-wide information can replace pedigree information for different objectives and is a valuable tool in the fields of genetic conservation and breeding.

The cotton historical lines project—Part I: History and field evaluation
Abstract Common garden experiments have provided great insights into crop adaptation across many systems. Cotton (Gossypium spp.) cultivars have changed in the 20th and 21st centuries, but breeders have not quantified the degree of these changes. We synthesized a panel of 164 non‐genetically modified genotypes, from the private and public sectors ...

Genomic variation in a widespread Neotropical bird (Xenops minutus) reveals divergence, population expansion, and gene flow [PDF]
Elucidating the demographic and phylogeographic histories of species provides insight into the processes responsible for generating biological diversity, and genomic datasets are now permitting the estimation of histories and demographic parameters with ...

Management of genetic diversity in small farm animal populations*
Many local breeds of farm animals have small populations and, consequently, are highly endangered. The correct genetic management of such populations is crucial for their survival.

Global population divergence and admixture of the brown rat (Rattus norvegicus) [PDF]
Native to China and Mongolia, the brown rat (Rattus norvegicus) now enjoys a worldwide distribution. While black rats and the house mouse tracked the regional development of human agricultural settlements, brown rats did not appear in Europe until the ...

Analysis of Genetic Variation of Rice Straw Characteristics and Its Influence on Biomass
ABSTRACT Rice straw is a key source of lignocellulosic biomass. GWAS can be used to identify genetic loci controlling stem morphological traits that influence biomass. This study aimed to investigate the genotypic diversity of rice straw internodes through GWAS, using 34,232 single‐nucleotide polymorphic sites with a minor allelic frequency (MAF ...
