The Role of KN1 in Plant Development
Cell communication is an ubiquitous feature of plant development; plant cells divide, expand, and differentiate in concerted action. Genetically distinct cells adopt alternate fates depending on their neighbors, in fact, the fates of all cells are most decisively determined by their neighbors. The question remains, not whether cell communication signals play a role, but what are these signals and how do they function? I will discuss areas of development that high-light the role of cell communication, and then suggest that KN1 may be one of the mediators.
