Feeling stressed? So is the poplar
Date:5/6/2010

People aren't the only living things that suffer from stress. Trees must deal with stress too. It can come from a lack of water or too much water, from scarcity of a needed nutrient, from pollution or a changing climate. Helping trees and crops adapt to stress quickly and efficiently is a pressing goal of plant biologists worldwide.

Now research led by Michigan Technological University scientists has identified the molecular mechanism that Populusthe scientific name for common poplars, cottonwoods and aspensuses to adapt to changing soil conditions, as well as some of the genes that turn the process off or on. They hope to apply what they've learned to find ways to use biotechnology or selective breeding to modify the trees to make them more stress-tolerant.

"Our hope is that by understanding how this works, we can manipulate the system so the plants can adapt faster and better to stressful conditions," explained Victor Busov, associate professor in Michigan Tech's School of Forest Resources and Environmental Science and senior author on a paper published in the March 2010 issue of the journal The Plant Cell.

Busov and colleagues at Michigan Tech, the University of Georgia, Oregon State University and the Beijing Forestry University in China analyzed thousands of genes in the Populus genome, the only tree genome that has been completely sequenced. They were searching for the mechanism that regulates the plant's decision to grow tall or to spread its roots out in an extensive underground exploration system that can sample the soil near and far until it finds what the rest of the plant needs.

The key players turned out to be a family of hormones called gibberellins, referred to by the scientists as GAs.

"GAs' role in root development is poorly understood," said Busov, "and the role of GAs in lateral root formation is almost completely unknown." Lateral roots are the tangle of tiny roots that branch out fr
