Molecular and Morphological Characterization of the Corn Cyst Nematode, Heterodera zeae, from Greece.

ABSTRACT: The corn cyst nematode Heterodera zeae was detected in soil from an organic maize field in northern Greece. In greenhouse studies, reproduction of H. zeae was detected on maize plants (Zeae mays) using soil high in organic matter; the field was under winter fallow at the time of sampling. Maize plants were grown in a greenhouse with soil from the affected field used as inoculum. Females appeared after six weeks incubation, and abundant cysts were present after 12 weeks. Morphological and molecular diagnosis confirmed the presence of H. zeae in the field. Cysts were identified on the basis of cyst shape and characteristics of the cyst terminal cone, including nature of fenestration, presence of bullae, cyst wall pattern, and fenestral diameter. Second-stage juveniles were identified by body
