Plant-cyst nematode and plant-root-knot nematode interactions

Parasitology Today, 1994
Root-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 ...

PATHOLOGY OF CYST‐NEMATODES

Biological Reviews, 1977
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

1992
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.

The Pea Cyst Nematode

1986
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 ...

Potato cyst nematodes

1992
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 ...
