Systematic contributions to Heteroderidae include description of Cactodera eremica n. sp., an emended diagnosis of Sarisodera Wouts and Sher, 1971, and proposal of a new genus and new combination, Afenestrata africana (synonym Sarisodera africana Luc et al., 1973). Cactodera eremica, from the roots of shadscale in Utah, most closely resembles Cactodera thornei (Golden and Raski, 1977) but diffe...

Plant-parasitic cyst nematodes secrete a complex of cell wall-digesting enzymes, which aid in root penetration and migration. The soybean cyst nematode Heterodera glycines also produces a cellulose binding protein (Hg CBP) secretory protein. To determine the function of CBP, an orthologous cDNA clone (Hs CBP) was isolated from the sugar beet cyst nematode Heterodera schachtii, which is able to ...

Atalodera ucri, Wouts and Sher, 1971, and A. lonicerae, (Wouts, 1973) Luc et al., 1978, induce similar multinucleate syncytia in roots of golden bush and honeysuckle, respectively. The syncytium is initiated in the cortex; as it expands, it includes several partially delimited syncytial units and distorts vascular tissue. Outer walls of the syncytium are relatively smooth and thickest near the ...

Plant Health Progress doi:10.1094/PHP-RS-13-0107. Fusarium virguliforme (syn. Fusarium solani f. sp. glycines), the causal agent of sudden death syndrome, and Heterodera glycines, soybean cyst nematode (SCN), are econ...

Bacteria-like endosymbionts of females of the plant-parasitic nematodes Globodera rostochiensis and Heterodera goettingiana and juveniles of Heterodera glycines were first observed during transmission electron microscopy (TEM) studies conducted in the 1970s. These organisms were characterized as being rod-shaped, ranging in size from 0.3 to 0.5 microm in diameter and 1.8 to 3 microm in length a...

Actin is an abundant, highly expressed, and much conserved protein belonging to the actin–heat shock protein70–sugarkinase superfamily. The full-length messenger RNAs encoding actin were cloned and characterized from the plant-parasitic cyst nematodes Heterodera glycines and Globodera rostochiensis and from the free-living nematode Panagrellus redivivus. The actins from the plant-parasitic nema...
