(Phys.org) —A team of researchers at the University of Bonn has discovered that a certain species of nematode actually does better when exposed to defensive chemicals made by plants. In their paper published in the journal ...
A recent discovery could lead to easier genetic modification of plant varieties considered recalcitrant to standard methods, including varieties of economically important crops.
