Scientists Hope To Improve Genome-wide Association Studies With Two New Methods

University of California - San Diego As scientists probe and parse the genetic bases of what makes a human a human (or one human different from another), and vigorously push for greater use of whole genome sequencing, they find themselves increasingly threatened by the unthinkable: Too much data to make full sense of. In a pair of papers published in the April 25, 2013 issue of PLOS Genetics, two diverse teams of scientists, both headed by researchers at the University of California,...

A new technique will allow plant breeders to introduce valuable crop traits even without access to the full genome sequence of that crop. The technique, published in the journal Nature Biotechnology, links important agronomic traits in crop plants with active regions of the genome. Instead of requiring knowledge of the crop's complete genome, it identifies only expressed genes. "For many crop plants, markers are still lacking because of the complexity of some plants' genomes and the...

Max Planck scientists decode genes for a complex characteristic Organisms are adapted to their environment through their individual characteristics, like body size and body weight. Such complex traits are usually controlled by many genes. As a result, individuals show tremendous variations and can also show subtle gradations. Researchers from the Max Planck Institute for Evolutionary Biology in Plön have now investigated how evolution alters such traits through selection. To...

The genetics responsible for frequency-specific hearing loss have remained elusive until recently, when genetic loci were found that affected high-frequency hearing. Now, a study published today in the open access journal BMC Genetics reports, for the first time, genetic loci with effects that are limited to specific portions of the hearing frequency map, particularly those that are most affected in aging-related hearing loss. Presbycusis is the loss of hearing for high-pitched sounds that...

If Pygmies are known for one trait, it is their short stature: Pygmy men stand just 4'11" on average. But the reason why these groups are so short and neighboring groups are not remains unclear. Scientists have proposed various theories based on natural selection, including that Pygmies' reduced size lowered nutritional requirements, helped them better handle hot climates, or allowed them to reach sexual maturity at an earlier age. Now a new study of the Western African Pygmies in...

How long does it take a fruit fly to emerge from a cold-induced coma? How resistant is a fruit fly to starvation? How quickly can a fruit fly settle down after it is startled? The answer to these complex traits rests with genes, many of them that interact in complicated ways to produce an end result that is a phenotype or outward sign, said an international group of scientists, led by those from North Carolina State University, the Baylor College of Medicine Human Genome Sequencing Center...

Scientists have developed a new community resource that may act as a Rosetta stone for revealing the genetic basis of traits and disease. A paper in the Feb. 9 issue of Nature describes the Drosophila Genetic Reference Panel (DGRP), which provides the highest-resolution view to date, of the genome structure and variation in a population of 192 fruit flies with diverse traits. The study was led by Trudy Mackay, professor of genetics at North Carolina State University, in collaboration with...

Transformational Fruit Fly Genome Catalog Completed

Scientists searching for the genomics version of the holy grail — more insight into predicting how an animal's genes affect physical or behavioral traits — now have a reference manual that should speed gene discoveries in everything from pest control to personalized medicine. In a paper published Feb 8 in Nature, North Carolina State University genetics researchers team with scientists from across the globe to describe the new reference manual — the Drosophila...

A large-scale study analyzing metabolic compounds in rice grains conducted by researchers at the RIKEN Plant Science Center (PSC) and their collaborators has identified 131 rice metabolites and clarified the genetic and environmental factors that influence their production. The findings provide a natural way to bioengineer improved rice grain varieties by selectively increasing production of useful metabolites, boosting the nutritional value of crops. As one of the most important staple...

Annals of Human Genetics
2012-05-07 06:56:58

The Annals of Human Genetics is a peer-reviewed scientific journal established in 1925 as the Annals of Eugenics by Karl Pearson, who was also the founder of Biometrika in 1901. Annals of Eugenics was changed to its current moniker in 1954 to reflect the changing views on the role of eugenics in society. It is published by Wiley-Blackwell in association with the University College, London. As of May 2012, its editor-in-chief is Andres Ruiz-Linares. The Institute for Scientific Information...
