But selective breeding also can drive the loss of other potentially useful characteristics, such as resistance to insect pests or environmental stresses including drought and flood. In a new review paper, which published today in Trends in Plant Science, researchers from the University of Copenhagen propose to identify genes responsible for these characteristics and—in a twist on "rewilding," a conservation concept that aims to bring landscapes back to an allegedly more natural state—genetically engineer modern crops to be more like their heartier ancestors.
As costs go down and ease of use goes up, more and more drones are going to enter American skies.
