Despite being closely related to the lyre-leaved rock cress, the thale cress has a considerably smaller genome It would appear reasonable to assume that two closely related plant species would have similar genetic blueprints. However, scientists from the Max Planck Institute for Developmental Biology in Tbingen, working in cooperation with an international research team have now decoded, for the first time, the entire genome of the lyre-leaved rock cress (Arabidopsis lyrata), a close...

Thematic program focuses on DNA replication, recombination and repair DNA's role as the master blueprint of the cell means that even small sequence changes can have catastrophic consequences. For this reason, much of our understanding of cancer development comes from studying how cells copy DNA and repair sequence errors -- and how these processes can go wrong. Next week, a thematic program at the American Society for Biochemistry and Molecular Biology's annual meeting at the Experimental...

New method for studying gene regulation Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have developed a new method for studying gene regulation, by employing a jumping gene as an informant. Published online today in Nature Genetics, the new method is called GROMIT. It enables researchers to systematically explore the very large part of our genome that does not code for proteins, and which likely plays a large role in making each of us unique, by...

University of British Columbia researchers have identified a small virus that attacks another virus more than 100 times its own size, rescuing the infected zooplankton from certain death. The discovery provides clues to the evolutionary origin of some jumping genes found in other organisms. The study, by UBC marine microbiologist Curtis Suttle and PhD student Matthias Fischer, is published online today in Science Express. It describes the marine virus Mavirus and its interaction with marine...

Presence of 'jumping genes,' amplified oncogenes may be key to tumor progression The Massachusetts General Hospital (MGH) research team that first discovered tumor-associated RNA in tiny membrane-enclosed sacs released into the bloodstream by cancer cells has now found that these microvesicles also contain segments of tumor DNA, including retrotransposons "“ also called "jumping genes" "“ that copy and insert themselves into other areas of the genome. The investigators' report,...

RIPs are alive and well -- and moving -- in the human genome An ambitious hunt by Johns Hopkins scientists for actively "jumping genes" in humans has yielded compelling new evidence that the genome, anything but static, contains numerous pesky mobile elements that may help to explain why people have such a variety of physical traits and disease risks. Using bioinformatics to compare the standard assembly of genetic elements as outlined in the reference human genome to raw whole-genome data...

Teams of international scientists have unlocked the genetic code of the wild strawberry and a certain type of cacao used to make fine chocolate, in a breakthrough that could lead to even more scrumptious versions of the treats. The work should help breeders develop a new generation of "Ëœsuper strawberries' and rich chocolate after identifying the chemicals responsible for their flavorful aroma and nutritional value. The wild strawberry is closely related to other crops such as...

New research finds that crop-killing mildews are able to sneak into plants undetected as "stealth bombers" by shedding genes to conceal themselves thus thwarting the plants' defenses. In a pair of studies, researchers mapped the genomes of two of the plant-killing mildews, and then described how the diseases shed giveaway genes to trigger an immune attack in the host plants. Although powdery mildew plagues seem to come out of nowhere,  they can devastate barley, corn, grapes, potatoes...

Scientists have sequenced the genome of a major fungal disease that affects barley and other cereal crops, a breakthrough that could lead to significant advances in our understanding of how plant diseases evolve Scientists have sequenced the genome of a major fungal disease that affects barley and other cereal crops, a breakthrough that could lead to significant advances in our understanding of how plant diseases evolve. The research, published today in the journal Science, suggests that...

Retroviruses are viruses made up of RNA genetic material. Endogenous retroviruses (ERV) are those sequences derived from retroviral infections introduced into the germinal line cells that, being incorporated in the genome, are transmitted from generation to generation. According to a number of investigations, the expression of ERV can benefit the host if it is controlled; it can help, for example, in the protection of the embryo. However, given its pathogenic nature, ERV also tends to be...
