Glycinoeclepins, Natural Hatching Stimuli for the Soybean Cyst Nematode, <i>Heterodera Glycines</i>. I. Isolation

Abstract

Abstract Hatching stimuli, designated as glycinoeclepins, for the soybean cyst nematode (Heterodera glycines) have been isolated by repeated chromatography of the aqueous extracts of dried roots of kidney bean (Phaseolus vulgaris), one of the host plants of the nematode. One of these compounds, glycinoeclepin A, stimulates the hatching and emergence of larvae in vitro in highly diluted aqueous solutions.
