Plant cells are constantly bombarded with information to which they must react. Signal transduction, the means whereby cells construct responses to a signal, is a recently defined focus of research in plant biology. The application of biochemical and molecular genetic techniques has resulted in major advances in elucidating the mechanisms that regulate gene expression and in identifying components of many signal transduction pathways in diverse physiological systems. Today, signal transduction research contributes to all aspects of plant science, linking many fields of study in much the same way that signal transduction pathways link myriad cellular processes.
