Functional genomic diversity is correlated with neutral genomic diversity in populations of an endangered rattlesnake

Proceedings of the National Academy of Sciences of the United States of America, 2023
Theory predicts that genetic erosion in small, isolated populations of endangered species can be assessed using estimates of neutral genetic variation, yet this widely used approach has recently been questioned in the genomics era. Here, we leverage a chromosome-level genome assembly of an endangered rattlesnake ( Sistrurus ...

Ecological disturbance reduces genomic diversity across an Alpine whitefish adaptive radiation [PDF]

Evolutionary Applications
Genomic diversity is associated with the adaptive potential of a population and thereby impacts the extinction risk of a species during environmental change.

CHARACTERISING DIVERSITY IN THE BRASSICA GENOMES

Acta Horticulturae, 2013
The genome sequence of an organism provides the basis for gene discovery, the analysis of genetic variation and the association of genomic variation with heritable traits. Genome sequence variation can vary from single nucleotide polymorphisms, insertions/deletions to presence/absence of large regions or rearrangements.

Ethical aspects of genome diversity research: genome research into cultural diversity or cultural diversity in genome research?

Medicine, Health Care and Philosophy, 2008
The goal of the Human Genome Diversity Project (HGDP) was to reconstruct the history of human evolution and the historical and geographical distribution of populations with the help of scientific research. Through this kind of research, the entire spectrum of genetic diversity to be found in the human species was to be explored with the hope of ...

Genome Surfing As Driver of Microbial Genomic Diversity

Trends in Microbiology, 2017
Historical changes in population size, such as those caused by demographic range expansions, can produce nonadaptive changes in genomic diversity through mechanisms such as gene surfing. We propose that demographic range expansion of a microbial population capable of horizontal gene exchange can result in genome surfing, a mechanism that can cause ...

Structural and Genomic Diversity of Bacteriophages

2023
Bacteriophage diversity is a relatively unknown frontier that is rapidly being explored, leading to a wealth of new information. New bacteriophages are being discovered at an astounding rate via both phage isolation studies and metagenomic analyses. In addition, a nucleotide sequence-based viral taxonomic system has been developed to better handle this

Genomic diversity in forest trees

Current Opinion in Plant Biology, 2007
Forest trees in general are out-crossing, long-lived, and at early stages of domestication. Molecular evolution at neutral sites is very slow because of the long generation times. Transferring information between closely related conifer species is facilitated by high sequence similarity.

Human genome diversity

Comptes Rendus de l'Académie des Sciences - Series III - Sciences de la Vie, 1998
Human genome diversity studies analyse genetic variation among individuals and between populations in order to understand the origins and evolution of anatomically modern humans (Homo sapiens sapiens). The availability of thousands of DNA polymorphisms (genetic markers) brings analytic power to these studies. Human genome diversity studies have clearly

Diversity of Genome Organisation

2012
Genomes can be organised in different ways. Understanding the extent of the diversity of genome organisation, the processes that create it, and its consequences is particularly important for two key reasons. Firstly, it is relevant for our understanding of the genetic basis for the astounding diversity of life on Earth.
