Gibberellins (GAs) constitute a large family of tetracyclic diterpenoid carboxylic acids, some members of which function as growth hormones in higher plants.

By yeast two-hybrid and coimmunoprecipitation assays, we report that P2 of RDV interacts with ent-kaurene oxidases, which play a key role in the biosynthesis of plant growth hormones gibberellins, in infected plants.

Since human and rat growth hormones also enhance guanylate cyclase activity, it appears that at cellular level the mechanism of action of growth promoting hormones may include a common process that involves enhancement of guanylate cyclase activity.
