Reversible flower opening regulated by CPK16-dependent phosphorylation and activation of aquaporin PIP2;2 in Gentiana.. Gentiana scabra

Flower opening is important for successful pollination in many plant species. However, the molecular mechanism(s) involved in flower movement are largely unknown. We propose that reversible flower opening is regulated by CPK-dependent aquaporin phosphorylation and activation, with stimulus-induced calcium signals acting as triggers.
