title: Biotransformation of potato stress metabolites rishitin, lubimin, and 15-dihydro lubimin by potato and soybean cell cultures.
abstract: Potato callus and cell suspensions of potato and soybean were exogenously supplied with potato phytoalexin rishitin, much of which was converted by both species to an unknown tenatively identified as glutinosone. Exogenous lubimin was unaffected by the potato cell culture, but was transformed to 15-dihydro lubimin by the soybean cell suspensions. The stability of the exogenous lubimin may be ascribed to a second block in the rishitin pathway of the potato cell culture.
