Active genetics technology opens new horizons

In 2015, University of California San Diego biologists Ethan Bier and Valentino Gantz developed a breakthrough technology known as "active genetics," which results in parents transmitting a genetic trait to most of their ...

Bacterial superheroes may save the day for crops

The bacterium SA187 has been isolated from the root nodules of an indigenous desert plant that grows in Saudi Arabia. The KAUST team found it has many genes that promote plant growth in stressful environments.

Gene enhancers important despite apparent redundancy

Every cell in the body has the same DNA and genes, so a cell's properties and functions are determined by which genes are turned on. That's why it is critical to understand enhancers, short sections of non-coding DNA that ...

What is CRISPR gene editing, and how does it work?

You've probably read stories about new research using the gene editing technique CRISPR, also called CRISPR/Cas9. The scientific world is captivated by this revolutionary technology, since it is easier, cheaper and more efficient ...

Plotting the path of plant pathogens

In a sneak attack, some pathogenic microbes manipulate plant hormones to gain access to their hosts undetected. Biologists at Washington University in St. Louis have exposed one such interloper by characterizing the unique ...
