Researchers have pioneered a new method which allows them to rapidly recruit disease resistance genes from wild plants and transfer them into domestic crops.
The technique called AgRenSeq or speed cloning has been developed by John Innes Centre researchers alongside colleagues in the United States and Australia to speed up the fight against pathogens that threaten food crops worldwide.
It enables researchers to search a genetic “library” of resistance genes discovered in wild relatives of modern crops so they can rapidly identify sequences associated with disease fighting capability.
From there researchers can use laboratory techniques to clone the genes and introduce them into elite varieties of domestic crops to protect them against pathogens and pests such as rusts, powdery mildew and Hessian fly.
