During the century-long history of plant hormone research, the focus in this area has shifted from the original physiological experiments to molecular, genetic, biochemical, and, more recently, genomic approaches. During this journey, we have learned about the many effects these natural compounds have on plant growth and development at the morphological and molecular levels. We have also uncovered how these molecules are sensed by the plant cell and how they trigger signaling cascades that relay information to the nucleus, ultimately culminating in a transcriptional cascade.
