Isolation and characterization of phytotoxins associated with Streptomyces scabies
Abstract
Two phytotoxins capable of inducing scab-like lesions on immature potato tubers were isolated from field grown and aseptically cultured potato tubers that had been infected by Streptomyces scabies; the compounds were characterized by spectral methods and partial syntheses as unique 2,5-dioxopiperazines.
