Plant-cyst nematode and plant-root-knot nematode interactions
Parasitology Today, 1994Root-knot nematodes and cyst nematodes are obligate plant parasites that cause extensive damage to the agriculture of both temperate and tropical countries. In this review, Andreas Niebel, Godelieve Gheysen and Marc Van Montagu describe how, in the past decade, the use of molecular techniques has provided new insights in the complex interactions ...

Summary1. The cyst‐nematodes, which belong to the genus Heterodera Schmidt, are obligate plant parasites. Several species cause crop diseases of economic importance. These nematodes differ greatly in structure from the other, vermiform, plant‐parasitic and soil‐inhabiting nematodes, for although the migrant larval phase of cyst‐nematodes is vermiform ...

Beet cyst nematode (Heterodera schachtii Schmidt) can cause ‘sickness’ in sugar beet, mangels and red beet where host crops of the nematode have been grown too frequently in the rotation. Beet cyst nematode occurs, and is a potential threat to intensive sugar beet cropping, in all temperate countries.

Liebscher (1890) reported a disease of pea (Pisum sativum L.) caused by nematodes in an experimental field at the Agriculture Institute at Gottingen. At first he attributed the damage to a strain of Heterodera schachtii Schmidt, but further studies on morphology and biology led to the conclusion that the nematode was a new species which was named ...

There are two distinct species of potato cyst nematode (Globodera rostochiensis (Wollen-weber) Behrens and Globodera pallida (Stone) Behrens) and both are major pests of the potato crop in temperate regions of the world. One or both species have been well established for many years in the main ware-potato growing districts of England and infestations ...

Cereal cyst nematode (Heterodera avenae Wollenweber) is a widely distributed pest of cereal crops, occurring in Britain, Ireland, various other northern European countries, Israel, India, Australia and N. America. In Britain it is more damaging to oats than to other cereals and is prevalent mainly on light-textured soils.

Pea cyst nematode (Heterodera goettingiana Liebscher) is a serious pest of peas and probably the most difficult to control. It was reported in Germany in 1890 and was first found in Britain in 1912. Since that time it has appeared in widely scattered localities, especially in gardens and allotments.
