Beating potato cyst nematodes

摘要

Leeds University's genetically modified potato trials, recently given the go-ahead by DEFRA, will research two possible methods to resist infection by potato cyst neniatodes. The small field trial involves growing about 400 plants, which have been genetically modified with the introduction of one of two proteins, says Peter Urwin from the university. "The first involves the introduction of a protein to the root of the potato plant, which when eaten by the nematode prevents it from digesting other proteins in its diet.
