Gibberellin-deactivating GA2OX enzymes act as a hub for auxin–gibberellin cross talk in Arabidopsis thaliana root growth regulation

Proceedings of the National Academy of Sciences, Volume 122, number 30, July 2025.
The growth and development of plants of importance depend on the precise regulation of cellular extension. Gibberelline phytohormone promotes cellular extension, while high levels of auxin inhibit root growth. This study reveals that the auxin regulates gibberelline …
