(Helmholtz Association of German Research Centres) Scientists at the Helmholtz-Zentrum für Infektionsforschung in Braunschweig, Germany. have achieved an important advance in better understanding metabolic pathways in bacteria.

Using computer models, the "System and Synthetic Biology" working group, headed up by Vítor Martins dos Santos, calculated the genetic changes that are necessary for increasing the production of biosynthetics in the Pseudomonas putida bacteria.

The well-known science magazine, PLoS Computational Biology published the results today.

Though bacteria are everywhere -- from the air we breathe and the food we eat to our guts and skin -- the vast majority are innocuous or even beneficial, and only a handful pose any threat to us.

What distinguishes a welcome microbial guest from an unwanted intruder?

A microchip-based device that detects and analyzes tumor cells in the bloodstream can be used to determine the genetic signature of lung tumors, allowing identification of those appropriate for targeted treatment and monitoring genetic changes that occur during therapy.


 

Transgenic Papaya Genome Draft Yields Many Fruits

ScienceDaily  Thu, 04/24/2008 - 13:00

Researchers have produced a first draft of the papaya genome. This draft sheds new light on the evolution of flowering plants.

And because it involves a genetically modified plant, the newly sequenced papaya genome offers the most detailed picture yet of the genetic changes that make the plant resistant to the papaya ringspot virus.


 

Bioterrorism: Outbreak Strains Can Be Quickly Analyzed With Next...

ScienceDaily  Thu, 04/10/2008 - 23:00

Following an outbreak or a bioterrorist attack, standard DNA sequencing and analysis of a pathogen genome for rapid identification of genetic changes or manipulations is time-intensive and likely impractical during an emergency.

Researchers have now developed a comparative genomics strategy to drastically reduce the time needed to accurately identify unique genetic properties of a potential outbreak strain.
