The newly assembled genomes of 26 different genetic lines of corn illustrate the crop’s rich genetic diversity and lay the groundwork for a better understanding of what genetic mechanisms account for crop traits prized by farmers. The mapping of the 26 genomes, published recently in the journal Science, was a team effort co-led by University of Georgia’s Kelly Dawe that will help scientists piece together the puzzle of corn genetics. Using these…

DNA activity can change without changing the sequence of the DNA segment itself. Gene activation and inactivation can be the basis for how species produce unique individuals. Some processes that change gene activity are well understood in the context of model species. However, scientists are still grappling with how some processes, like DNA methylation, change gene activity in many diverse organisms. Broader theories applicable to all species…

A new breeding technique using a plant's own DNA could produce crops that are more resistant to drought and disease: A team of University of Georgia researchers has developed a new way to breed plants with better traits. By introducing a human protein into the model plant species Arabidopsis thaliana, researchers found that they could selectively activate silenced genes already present within the plant. Using this method to increase diversity…

Great news for students in our introductory biology courses: The University of Georgia Center for Teaching and Learning is looking at ways to save students money by offering free e-textbooks for introductory biology courses at UGA through a $25,000 University System of Georgia Incubator grant awarded this summer. UGA students who take the entry-level biology courses pay around $97 for a new biology textbook. This grant will collectively save…
