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 variety
It is the plant that changed humanity. Thanks to the cultivation of wheat,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.
But the crisis could be averted thanks to a remarkable project now being undertaken by researchers at the John Innes Centre in Norwich. They are working on a project to make wheat more resistant to heat and drought. Such efforts have proved to be extremely tricky but are set to be the subject of a new set of trials in a few weeks as part of a project in which varieties of wheat – created, in part, by gene-editing technology – will be planted in field trials in Spain.
The problem that has faced crop scientists, who have been seeking to improve the resilience and productivity of wheat varieties, has been the complexity of wheat genetics, Moore added. “Human beings have a single genome that contains our DNA instructions. But pasta wheat has two different ancestral genomes while bread wheat has three.”
