Shuffling the deck: plant signalling plays a club.
The transmission of signals across the plasma membrane of cells plays an integral part in cell communication in unicellular and complex organisms. Protein kinases and their activators serve key roles in this process, and a number of paradigms have been established to describe their mode of action. Signalling in plant cells appears to shuffle these paradigms - as evidenced by two recent reports on the development of the Arabidopsis meristem.
