THE METABOLISM OF INDOLE BY TOMATO-PLANT TISSUES AND EXTRACTS

Abstract
Tomato-plant tissues and homogenates were found to metabolize indole. Tryptophan and indoleacetic acid were identified as reaction products, and in some instances serine was required for indole metabolism. The pH optimum for the reaction was about 5.0. Preparations from zinc-deficient tomato plants metabolized indole more efficiently than those from normal plants.
