| Effects of polyamines on ethylene biosynthesis were studied in synchronized suspension cultured cells from leaf segments of Nicotiana tabacum L. Putrescine, spermidine and spermine inhibited the endogenous production of both ACC and ethylene. Those production was more remarkably inhibited by spermidine and spermine than putrescine. These results were the same tendency with those obtained from exogenous application of SAM and ACC. Polyamines had more inhibitory effect on hte conversion of ACC to ethylene than that of SAM to ACC, but ACC was not accumulated. The inhibition rate of exogenously applied ACC conversion to ethylene was well coincident with that of exogenously applied SAM conversion to ethyene via ACC by polyamines. However, polyamines inhibited more the activity of ACC synthase than that of EFE. From these results we can suggest that polyamines inhibit both steps of SAM to ACC and ACC to ethylene, and more effectively the latter than the former. |
