Dr. Trudy Mackay and an international team of researchers provide the holy grail of fruit fly genetics -- a reference panel of genetic variation in 192 fruit fly lines.
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.


Researchers have now been able to sequence the entire Denisova genome using 10 milligrams of a finger bone fragment that was found in the Denisova Cave in Southern Siberia.
In 2010, Dr. Svante Pääbo and his colleagues presented a draft version of the genome from a small fragment of a human finger bone discovered in Denisova Cave in southern Siberia. The DNA sequences showed that this individual came from a previously unknown group of extinct humans that have become known as Denisovans. Together with their sister group the Neandertals, Denisovans are the closest extinct relatives of currently living humans.

Scientists have cracked the genetic code and predicted some high priority drug targets for the blood parasite Schistosoma haematobium, which is linked to bladder cancer and HIV/ AIDS and causes the insidious urogenital disease schistosomiasis haematobia in more than 112 million people in Africa.


This is a phylogenomic reconstruction of the evolutionary diversification of seed plants.
Scientists at the American Museum of Natural History, Cold Spring Harbor Laboratory, The New York Botanical Garden, and New York University have created the largest genome-based tree of life for seed plants to date. Their findings, published today in the journal PLoS Genetics, plot the evolutionary relationships of 150 different species of plants based on advanced genome-wide analysis of gene structure and function. This new approach, called "functional phylogenomics," allows scientists to reconstruct the pattern of events that led to the vast number of plant species and could help identify genes used to improve seed quality for agriculture.

An international team of scientists - including Ghent VIB scientists - has succeeded in deciphering the genome of the spider mite. This is also the first known genome of an arachnid. This premiere not only brings along new insights into the evolution of arthropods, but also offers new opportunities to develop means of crop protection against the spider mite.

The International Cooperation to Sequence the Atlantic Salmon Genome (ICSASG, the "Cooperation") has awarded the Phase II contract for next-generation sequencing and analysis of the Atlantic salmon genome to the J. Craig Venter Institute (JCVI) in Rockville, Maryland. The JCVI will be sequencing the salmon genome using next-generation technologies, including assembly to integrate Sanger and next-generation sequence, and comparative genomics. This effort is expected to generate a high-quality resource for those responsible for the management of wild salmon stocks and the salmon aquaculture industry, as well as providing a reference genome for work with other salmonids.

The Monarch butterfly is famous for its ability to travel up to 2,000 miles from North America to central Mexico every fall. Now, it's enjoying fame of a different sort. In the November 23rd issue of Cell, researchers report the full genomic sequence of this iconic butterfly. The new genome is the first for any butterfly. It is also the first complete genome of any long-distance migrant.

Scanning electron microscope image of a two-spotted spider mite, which is less than one millimeter long.
A University of Utah biologist and an international research team decoded the genetic blueprint of the two-spotted spider mite, raising hope for new ways to attack the major pest, which resists pesticides and destroys crops and ornamental plants worldwide.

BGI, the world's largest genomic organization, announces several bioinformatics analysis pipelines and software, including assembly and binning tools, genetic variation software, as well as two cloud-based green solutions for genomic-based research. In addition, GigaScience, an upcoming research journal published by BGI, announces the launch of its new, freely accessible, large-scale database: GigaDB. The launch of GigaDB is heralded by today's release of numerous large datasets of different types and from a variety of organisms. GigaDB is unique because it is directly affiliated with a journal and all of its datasets are assigned a Digital Object Identifier (DOI), which allows these data to be directly cited in future publications.

A 79-year-old collection of fungal cultures and the U.S. Forest Service's Northern Research Station are part of a team that will sequence 1,000 fungal genomes in the next 5 years.

Precise diagnosis of disease and developmental syndromes often depends on understanding the genetics underlying them. Most cases of early onset hearing loss are genetic in origin but there are many different forms. Heretofore, it has been difficult to identify the gene responsible for the hearing loss of each affected child, because the critical mutations differ among countries and populations. New research published in BioMed Central's open access journal Genome Biology has identified six critical mutations in Israeli Jewish and Palestinian Arab families. Mutations in one gene, TMC1, was found in 38% of children with genetic hearing loss in the Moroccan Jewish population.

A study involving more than 200,000 people worldwide has identified 29 DNA sequence variations in locations across the human genome that influence blood pressure. These genes, whose sequence changes are associated with alterations in blood pressure and are linked to heart disease and stroke, were found with the help of decades' worth of population data that were pooled and analyzed by a large international consortium, including Johns Hopkins researchers.

The green anole lizard is an agile and active creature, and so are elements of its genome. This genomic agility and other new clues have emerged from the full sequencing of the lizard's genome and may offer insights into how the genomes of humans, mammals, and their reptilian counterparts have evolved since mammals and reptiles parted ways 320 million years ago. The researchers who completed this sequencing project reported their findings August 31 online in the journal Nature.

What Google is attempting for books, the University of California, Berkeley, plans to do for the world's vertebrate specimens: store them in "the cloud."


Proteins are essential components of Arabidopsis parts, such as petals, stalks and flowers. The genetics of these essential proteins were previously identified through studies involving genome sequencing.
An international consortium of scientists has produced the first systematic network map of interactions that occur between proteins in the plant Arabidopsis thaliana. (Arabidopsis is a mustard plant that has 27,000 proteins and serves as a popular model organism for biological studies of plants, analogous to lab rats that serve as popular model organisms for biological studies of animals.)

In the decade that has passed since the completion of the first draft sequence of the human genome, biologists have grown increasingly aware of a problem ironically generated by the success of their work. Biological experiments in the age of genomics -- including DNA sequencing, gene expression profiles, studies of cell-signaling pathways, protein binding, and other information-rich inquiries -- generate quantities of raw data so immense that they threaten to overwhelm researchers' ability to make sense of them.


These are various types of potatoes that are grown in Peru. These potatoes differ in shape, skin pigmentation and flesh pigmentation.
An international consortium of scientists has produced a new map of the potato genome that may lead to the development of an ultra-nutritious potato that could help feed the world's hungry.

BioMed Central and BGI launch a new integrated database and journal, to meet the needs of a new generation of biological and biomedical research as it enters the era of "big-data."

An analysis of genomic changes in ovarian cancer has provided the most comprehensive and integrated view of cancer genes for any cancer type to date. Ovarian serous adenocarcinoma tumors from 500 patients were examined by The Cancer Genome Atlas (TCGA) Research Network and analyses are reported in the June 30, 2011, issue of Nature.


The Panamanian leaf-cutting ant Acromyrmex echinatior farms fungus on leaf fragments for food.
The development of agriculture was a significant event in human cultural evolution, but we are not the only organisms to have adopted an agricultural way of life. In a study published online today in Genome Research (www.genome.org), researchers have sequenced the genome of a fungus farming leaf-cutting ant, revealing new insights into the genetics and molecular biology behind this unusual lifestyle.

Navigating the human genome with software that you can view on an iPad® sounds pretty impressive, until perhaps you reflect that nature has already encoded trillions of copies of this in your chromosomes. Then again, printing that data using ink and paper would produce a mind-staggering pile of pages—so viewing it on an iPad® may be impressive after all.

Building upon previous efforts producing a high-quality de novo genome assemblies of deadly 2011 E. coli O104:H4 outbreak strain (http://www.genomics.cn/en/news_show.php?type=show&id=651), the BGI and their collaborators at the University Medical Centre Hamburg-Eppendorf have now released the first complete map of the genome and plasmids without any assembly gaps.

It's been called "the Manhattan Project of Entomology," an undertaking that has the potential to revolutionize the way we think about insects.

One of the world's most destructive wheat pathogens is genetically built to evade detection before infecting its host, according to a study that mapped the genome of the fungus.

Mice and humans share about 95 percent of their genes, and mice are recognized around the world as the leading experimental model for studying human biology and disease. But, says Jackson Laboratory Professor Gary Churchill, Ph.D., researchers can learn even more "now that we really know what a laboratory mouse is, genetically speaking."

The University of Minnesota's Consortium on Law and Values in Health, Environment & the Life Sciences will host a major conference on "Should We Return Research Results and Incidental Findings from Genomic Biobanks & Archives," from 8 a.m. to 5 p.m. Thursday, May 19, Bethesda, Md.

A team led by researchers at the National Institutes of Health is the first to systematically survey the landscape of the melanoma genome, the DNA code of the deadliest form of skin cancer. The researchers have made surprising new discoveries using whole-exome sequencing, an approach that decodes the 1-2 percent of the genome that contains protein-coding genes. The study appears in the April 15, 2011, early online issue of Nature Genetics.

Researchers have built a computer model of the crowded interior of a bacterial cell that – in a test of its response to sugar in its environment – accurately simulates the behavior of living cells.

Scientists on the Norwich Research Park have sequenced the genome of a novel strain of Clostridium botulinum, one of the most dangerous pathogens known to man. The strain produces an unusual botulinum neurotoxin, known as type A5 neurotoxin, which was isolated by the Health Protection Agency (HPA), following a case of wound botulism.

Algae play key roles in the global carbon cycle, helping sequester significant amounts of carbon. Some algal species can bloom, or become so numerous, that they discolor coastal waters and reduce the amount of light and oxygen available in the ecosystem. Previously known as "red tide," the term "harmful algal blooms" (HABs) was introduced two decades ago to note accumulation of algal biomass can sometimes also turn the ocean waters brown or green and disrupt an ecosystem, or that red-colored waters can sometimes be harmless.
