This issue of The Scientist peels back layers of complexity to report on the science that is revolutionizing nutrition and agriculture from the inside out. What we’ve uncovered is a cornucopia of technical progress in plant breeding spurred by advances in genomics and gene editing—advances that could feed many more people and counter climate-change threats to food crops.
In “Putting Up Resistance,” associate editor Kerry Grens documents crop scientists’ growing worries that a fungal attack on wheat plants could spread around the world, decimating a crop with insufficient defense mechanisms before breeders can develop a more resistant variety. She outlines the progress ...
