‘Holy grail’ wheat gene discovery could feed our overheated world

Harvests that form a vital element of the diets of 4.5 billion people are being devastated by global heating. Now research has found a key to create a heat-resistant varietyIt is the plant that changed humanity. Thanks to the cultivation of wheat,homo sapiens was able to feed itself in ever-increasing numbers, transforming groups of hunter-gatherers struggling to survive in a hostile world into rulers of the planet.In the process, a species of wild grass that was once confined to a small part of the Middle East now covers vast stretches of the Earth.
