Abstract
|
|
|
|
Spermidine, spermine and IAA promoted an increase in β-1,4-endoglucanase activity in hypocotyls of Clycine max. The optimal concentration for the increase of the enzyme activity was 10^-6 M for spermidine, 10^-8 M for spermine and 10^-6 M for IAA. However, IAA had innocuous effect on arginine decarboxylase and ornithine decarboxylase activities, and the content of polyamine. Such cumulative results suggest that the increase in β-1,4-endoglucanase activity by IAA is not attributed by the effect on the biosynthesis of polyamine by IAA but spermidine, spermine and IAA induce cell wall loosening and therefore extension growth of cells.
