<< During their life, plants constantly renew themselves. They sprout new leaves in the spring and shed them in the fall. >>
<< When it is time to shed an organ, a small hormone binds to this membrane receptor and, together with a helper protein, the abscission process is initiated. >>
<< To fully initiate the abscission process, another player is needed: the helper protein SERK1. >>
<< The fascinating thing about SERK1 is that it not only plays a role in the shedding mechanism of plant organs, but also acts together with other membrane receptors that regulate totally different aspects of plant development >>
<< Indeed, SERK1 is a versatile helper protein shared between different signaling pathways. When bound to another protein receptor, it can also for example signal the plant to grow. >>
