Genetics and conservation biology

Comptes Rendus. Biologies, 2003
Conservation genetics encompasses genetic management of small populations, resolution of taxonomic uncertainties and management units, and the use of molecular genetic analyses in forensics and to understanding species' biology. The role of genetic factors in extinctions of wild populations has been controversial, but evidence now shows that they make ...

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS

FEBS Letters, EarlyView.
We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

The Collection, Evaluation and Conservation of Plant Genetic Resources [PDF]

, 1972
Report on the findings of a meeting of a TAC Ad Hoc Working Group held at the USDA Research Center in Beltsville, Maryland in March 1972. The working group was asked to provide advice on an action program for the conservation of plant genetic resources ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Seeing the Forest for the Trees: Threats, Vulnerabilities, and Opportunities for Woody Landscape Plant Genetic Resources

HortScience
Genetic resources are the foundation of American agriculture’s ongoing success—the diversity, security, health, and genetic integrity of these resources must be safeguarded. However, in contrast to other crops, protecting, managing, and using collections

Evolution of Foamy Viruses: The Most Ancient of All Retroviruses

Viruses, 2013
Recent evidence indicates that foamy viruses (FVs) are the oldest retroviruses (RVs) that we know and coevolved with their hosts for several hundred million years. This coevolution may have contributed to the non-pathogenicity of FVs, an important factor

Horses as Sources of Proprietary Information: Commercialization, Conservation, and Compensation Pursuant to the Convention on Biological Diversity [PDF]

, 2014
Horses indigenous to East and Southeast (E/SE) Asia, including native, landrace, feral, and wild populations, embody valuable genetic diversity. Conservation efforts for animals have largely been driven by humane altruism, with little consideration for ...

Conservation Genetics, Precision Conservation, and De‐extinction [PDF]

Hastings Center Report, 2017
AbstractIt has been estimated that three species on the planet now go extinct every hour and that this rate is orders of magnitude higher than the planet has seen in previous catastrophic extinction events. We clearly are in the midst of a sixth extinction, and this one is different from the previous five. Why?
