How plants respond to climate change

Posted 1 year 6 months ago

Jill Anderson, an assistant professor of genetics, has received a $1.1 million grant from the National Science Foundation Early Career Development Program to study the effects of climate change on plants. Among the NSF's most prestigious, CAREER awards support junior faculty who exemplify the role of teacher-scholar and the integration of education and research:

Anderson's project tests whether plants will be able to survive on a warming planet by using a mustard plant species called Drummond's rockcress as a model. Native to the Rocky Mountains, Drummond's rockcress can grow at...

CRISPR-associated proteins are some of the most promising new tools providing a way to make gene deletions, corrections of mutations and additions of new genes in any genome. Outstanding undergraduate researcher Erin Hollander, a junior Honors student majoring in biochemistry and genetics, was one of 60 presenters selected out of hundreds of applicants from institutions across the country to present her research at the nation's capital during the 20th annual Posters on the Hill event held in Washington, D.C., on April 19-20.

Beetles and the genetics of parenthood

Most insects do not care for their young. But burying beetles take an extraordinarily active role - preparing food, protecting the brood and even feeding their offspring much in the same way that a bird feeds its hatchlings. New research published in the journal Nature Communications has identified many of the genetic changes that take place in burying beetles as they assume the role of parent:

"Parenting is a complex trait, but it's particularly complex in burying beetles," said the study's co-author Allen Moore, a Distinguished Research Professor of Genetics in UGA's Franklin...

Slithering Enhancers

Snakes weren't always legless; they evolved the loss of limbs over 100 million years ago and new research from genetics explains why snakes have held on to this limb circuitry through the ages:

"There have been many millions of snake generations since they evolved a legless body, and we would generally expect the DNA associated with limb development to fade away or mutate to do another job, but that doesn't seem to have happened," he said. "Naturally, we wanted to know why snakes had retained DNA that they don't appear to need."

In their experiments, Menke and postdoctoral...

When thieving weeds attack

Posted 2 years 4 months ago

An international group of scientists that includes assistant professor of genetics Dave Nelson has discovered how parasitic plants, which steal their nutrients from another living plant, evolved the ability to detect and attack their hosts. Their findings were  published recently in the journal Science:

As plant roots grow, they release hormones called strigolactones into the soil. This is a signal that normally helps fungi form a beneficial connection to the plant, in which they each trade nutrients. But the seeds of parasitic plants also possess the ability to sense strigolactones...
