Abstract
Calluses were produced from plant tissues of Japanese cycad (Cycas rev oluta Thunb.). Its toxic component named cycasin, beta-glucoside of me thylazoxymethanol, was formed by the calluses only in the presence of exogenous methylazoxymethanol. A glucosyltransferase catalysing the fo rmation of cycasin from UDP-glucose and methylazoxymethanol occurred i n the calluses. The properties of this enzyme in embryo-derived callus and in leaf tissue were similar.
