Abstract：
:[(3)H](+)-delta-Cadinene and its 8-hydroxy derivative, prepared from (1RS)-[1-(3)H]FPP by the action of one and two recombinant enzymes, respectively, were infiltrated into cotyledons of bacterial blight-resistant cotton plants as they biosynthesized sesquiterpene phytoalexins in response to infection by Xanthomonas campestris pv. malvacearum. Following both treatments, tritium appeared in the HPLC fraction that contained hemigossypol. Hemigossypol was isolated from the cotyledons that had been treated with [(3)H](+)-8-hydroxy-delta-cadinene and was trimethylsilylated and purified. In two experiments, specific radioactivity of the hemigossypol derivative indicated that 5% and 10%, respectively, of the [(3)H](+)-8-hydroxy-delta-cadinene had been converted to hemigossypol.
