On the Breeds of Cattle—Historic and Current Classifications
Classification of cattle breeds contributes to our understanding of the history of cattle and is essential for an effective conservation of genetic diversity.

Genebanks were established out of a recognised need not just to provide genetic variation to support breeding objectives but to prevent crop diversity from being lost entirely for future users. Such conservation objectives may have led, over the past few

Natural recovery of genetic diversity by gene flow in reforested areas of the endemic Canary Island pine, Pinus canariensis [PDF]
The endemic pine, Pinus canariensis, forms one of the main forest ecosystems in the Canary Islands. In this archipelago, pine forest is a mosaic of natural stands (remnants of past forest overexploitation) and artificial stands planted from the 1940's. The genetic makeup of the artificially regenerated forest is of some concern. The use of reproductive

Genetic diversity of noroviruses in Brazil [PDF]
Norovirus (NoV) infections are a major cause of acute gastroenteritis outbreaks around the world. In Brazil, the surveillance system for acute diarrhoea does not include the diagnosis of NoV, precluding the ability to assess its impact on public health. The present study assessed the circulation of NoV genotypes in different Brazilian states by partial

Genetic Diversity in Weeds [PDF]
Weeds growing in cultivated areas are usually characterized as having high phenotype plasticity and genetic adaptability. They are frequently well-adapted to disturbance and often seed prolifically (Adahl et al., 2006). Thus, improving the current knowledge on the genetic diversity of weed populations is a challenge for management, primarily because ...

Visualization of the impatiens downy mildew pathogen using fluorescence in situ hybridization (FISH)
Background Plasmopara obducens is the biotrophic oomycete responsible for impatiens downy mildew, a destructive disease of Impatiens that causes high crop loss. Currently, there are no available methods for the microscopic detection of P.

Worldwide phylogeography and history of wheat genetic diversity
A phylogeographical study reveals the reshuffling of wheat genetic diversity through time, in relation to human history. Since its domestication in the Fertile Crescent ~8000 to 10,000 years ago, wheat has undergone a complex history of spread ...

IntroductionPhytolacca acinosa Roxb. is a highly valuable multipurpose herb native to the Himalayan region. Unsustainable harvesting of this species due to its diverse uses has resulted in a rapid decline in its population across natural habitats ...

Human genetic admixture through the lens of population genomics [PDF]
Over the last fifty years, geneticists have made great strides in understanding how our species' evolutionary history gave rise to current patterns of human genetic diversity classically summarized by Lewontin in his 1972 paper, 'The Apportionment of Human Diversity'.

Plant genetic resources (PGR) have been used in breeding programs for many decades to produce modern varieties by introducing genes of interest, in particular, resistance genes.
