ABSTRACT
Fett and Zacharius (1982, 1983) demonstrated that bacteria as well as fungal cell wall elicitors can induce the accumulation of the phytoalexin glyceollin in soybean (Glycine max L. Merr.) cell suspension cultures. Moreover, the typical hypersensitive response (HR) as defined by rapid host cell death displayed by the intact plant was not a prerequisite for phytoalexin induction in soybean cell cultures. The concentration of glyceollin produced declined with successive culture transfers. Some interesting responses by separate cell lines of the same cultivar to challenge with a biotic agent were observed, suggesting further study.
