Gibberellin structure and function: Biological activity and competitive inhibition of gibberellin 2- and 3-oxidases
Some gibberellin (GA) analogues, especially with C-16,17 modifications of GA5, can inhibit growth of plants apparently by acting as competitors with the endogenous substrate of GA biosynthetic enzymes. Here, we directly confirm the competitive action of GA derivatives but also show that some analogues may retain significant bioactivity. A recombinant 3-oxidase from pea, which converts GA20 to bioactive GA1, was inhibited by GA5, and 16,17-dihydro-GA5 derivatives, especially if the C-17 alkyl...[Show more]
