Abstract

R-25788 (N,N-diallyl-2,2-dichloroacetamide) had no effect on 14CO2 evolution from carbonyl-14C-EPTC (S-ethyl dipropylthiocarbamate) treated corn (Zea mays L. ‘inbred Oh551’). Treatment with 1.0 ppmw R-25788 increased production of water-soluble and unextractable products from EPTC and increased the rate of disappearance of organic-soluble radioactivity. R-25788 increased levels of reduced and oxidized glutathione in corn roots. Pretreatment of corn in nutrient solution with R-25788 had no effect on glutathione synthetase activity in root tissue, but R-25788 at 5.0 and 500.0 nM showed an in vitro stimulation of the enzyme.
