Abstract
Plant parasitic nematodes are a serious threat for crop production worldwide. This review summarizes our understanding of plant nematode interactions and presents new alternatives for nematode control in the field. Breeding for resistance has been a major goal for many important crop species like soybean, potato, tomato and sugar-beet. As a result numerous nematode-resistance genes have been identified, two of which have been cloned recently, Hs1 pro-1 from sugar-beet, giving resistance to the beet cyst nematode Heterodera schachtii, and Mi from tomato, giving resistance to the root-knot nematode Meloidogyne incognita. Also artificial resistance genes, coding for nematotoxic proteins or causing rapid death of feeding cells, have been elucidated. In the future, genetic engineering of nematode resistance will become more and more important for plant breeding. Transformation techniques will allow genes to be quickly introduced into susceptible breeding lines and then combined with each other to produce plant varieties with durable resistance.
