Abstract

EPTC (S-ethyl dipropylthiocarbamate), 1,8-naphthalic anhydride (NA), N,N-dialryl-2,2-dichloroacetamide (R-25788), CDAA (N,N-diallyl-2-chloroacetamide) and CDEC (2-chloroallyl diethyldithiocarbamate) at concentrations of 10-5 M inhibited the incorporation of acetate-1-14C (Ac∗) into fatty acids of isolated spinach (Spinacia oleracea L.) chloroplasts. Lower concentrations of these chemicals did not affect acetate incorporation into fatty acids. However, the inhibition by EPTC at 10-5 M was counteracted by NA and R-25788 [agriculturally important antidotes for EPTC injury to corn (Zea mays L.)] at 10-7 M.
