Colonization of land by plants is a major chapter in the history of plant evolution. Appearance of seeds has been essential for this success. A seed consists of a small encapsulated plant in a highly resistant and inert state awaiting favorable growth conditions to germinate and pursue its life cycle.

Seeds convert plants in time and space travelers providing them with protection and allowing their propagation.

However, protection and propagation must be accompanied by germination control mechanisms to avoid potentially fatal starts such as germination out of season or in the face of environmental changes affecting light or water quality. We are interested in understanding the control mechanisms allowing the plant to securely abandon its protective state within the seed.
