Rockefeller University Genomic sequencing is supposed to reveal the entire genetic makeup of an organism. For infectious disease specialists, the technology can be used to analyze a disease-causing bacterium to determine how much harm it is capable of causing and whether or not it will be resistant to antibiotics. But new research at Rockefeller University suggests that current sequencing protocols overlook crucial bits of information: isolated pieces of DNA floating outside the bacterial...

Duke University Ubiquitous protein controls copying of resistant DNA Staph infections that become resistant to multiple antibiotics don't happen because the bacteria themselves adapt to the drugs, but because of a kind of genetic parasite they carry called a plasmid that helps its host survive the antibiotics. Plasmids are rings of bare DNA containing a handful of genes that are essentially freeloaders, borrowing most of what they need to live from their bacterial host. The plasmids...

Genetically Altering E. Coli With New Semi-Synthetic DNA Base Pairs
2014-05-08 07:24:29

Lawrence LeBlond for redOrbit.com - Your Universe Online It is well-known that all life on Earth is made up of two base pairs, known as A-T (adenine–thymine) and C-G (cytosine–guanine), which form the standard double helix DNA strand. But that could all change now that researchers at The Scripps Research Institute (TSRI) have engineered a bacterium to contain an extra pair of DNA “letters” that are not found anywhere else in nature. The cells of this bacterium are also able to...

New insights into a surprisingly flexible immune system present in bacteria for combating viruses and other foreign DNA invaders have been revealed by researchers from New Zealand's University of Otago and the Netherlands. A team led by Dr Peter Fineran of the Department of Microbiology and Immunology are studying the genetic basis of adaptive immunity in bacteria that cause potato 'soft rot' and in E. coli bacteria. Through their recent collaboration they have found that these bacterial...

Glow In The Dark Piglets

[ Watch the Video: Glow In The Dark Piglets ] Lee Rannals for redOrbit.com - Your Universe Online Reproductive scientists in China have created pigs that glow in the dark, according a study that has been submitted for publishing in the Biology of Reproduction Journal. Ten transgenic piglets were born earlier this year that glow green under a black light or UVA light. The pigs represent a technique a team from Guangdong Province in Southern China developed that could help develop...

Bio Patch Regrows Bone
2013-11-07 15:53:46

Brett Smith for redOrbit.com - Your Universe Online University of Iowa researchers have developed a collagen scaffold capable of growing bone from within a living body, which could have massive ramifications for treating musculoskeletal problems. According to the team’s report in the journal Biomaterials, their novel collagen structure is seeded with particles containing the genetic instructions necessary for producing bone. In experiments, the gene-team was successfully able to...

DNA Inserted 'Gently' Into Living Cells Using New High-tech Laser Method
2013-08-08 09:51:43

The Optical Society Technique offers greater-than-ever control of essential gene therapy and genetic engineering method The applications of gene therapy and genetic engineering are broad: everything from pet fish that glow red to increased crop yields worldwide to cures for many of the diseases that plague humankind. But realizing them always starts with solving the same basic scientific question -- how to "transfect" a cell by inserting foreign DNA into it. Many methods already exist...

Next week's Journal of Biological Chemistry "Paper of the Week" by Wai Mun Huang and colleagues at the University of Utah Health Sciences Center and the University of Minnesota reveals new insights into the molecular properties of the rod-shaped soil bacterium Agrobacterium tumefaciens, the pathogen responsible for crown gall disease, a tumor-forming infection in plants, such as tomatoes, walnuts, grapes and beets. The bacterium is parasitic: It infects its plant host by entering through...

Agrobacterium tumefaciens is the causal agent of crown gall disease (the formation of tumours) in over 140 species of dicot. It is rod shaped. Symptoms are caused by the insertion of a small segment of DNA into the plant cell. It is an alphaproteobacterium of the family Rhizobiaceae which includes the nitrogen fixing legume symbionts. They are pathogenic and provide no benefit to the plant. It also affects a wide variety of plants. In an economical sense it affects walnuts, grape vines,...
