1,1-DIMETHYL-4-(PHENYLSULFONYL)SEMICARBAZIDE (DPSS) DOES NOT INHIBIT THE IN-VITRO ACTIVITIES OF 1-AMINOCYCLOPROPANE-1-CARBOXYLATE (ACC) OXIDASE AND ACC SYNTHASE OBTAINED FROM SENESCING CARNATION (DIANTHUS-CARYOPHYLLUS L.) PETALS
S. Satoh et al., 1,1-DIMETHYL-4-(PHENYLSULFONYL)SEMICARBAZIDE (DPSS) DOES NOT INHIBIT THE IN-VITRO ACTIVITIES OF 1-AMINOCYCLOPROPANE-1-CARBOXYLATE (ACC) OXIDASE AND ACC SYNTHASE OBTAINED FROM SENESCING CARNATION (DIANTHUS-CARYOPHYLLUS L.) PETALS, Plant growth regulation, 23(3), 1997, pp. 191-193
The effects of 1,1-dimethyl-4-(phenylsulfonyl)semicarbazide (DPSS) on
the in vitro activities of 1-aminocyclopropane-1-carboxylate (ACC) oxi
dase and ACC synthase isolated from senescing carnation petals were in
vestigated. In contrast to a previous proposal, DPSS at 1 mM did not i
nhibit the in vitro activity of ACC oxidase. It was confirmed that DPS
S does not inhibit ACC synthase activity. DPSS probably does not exert
its inhibitory action on ethylene production by a direct action on AC
C oxidase and ACC synthase, but by some unknown action.
