WebSignal transduction is the process where an external chemical signal elicits an intracellular metabolic change. The process begins with the binding of specific ligands to receptors located at the surface of the plasma membrane. The receptor responds to the binding of agonists in several different ways. This chapter discusses two mechanisms of ... WebProtein phosphatases (PPs) control a large number of signaling processes in plants, and their inhibition disrupts many cellular processes, leading to death. Endothall (Fig. 5) inhibits one family of PPs, the serine/threonine PPs and it is the only PP inhibitor herbicide.
