Abstract
The appearance of the techniques of developmental genetics is one of the most powerful strategies in efforts to understand the mechanisms of complex biological phenomena, such as leaf morphogenesis. However, developmental genetic analysis alone is insufficient for detailed characterization of the mechanisms that control such morphogenesis. Thus, physiological, biochemical, and biophysical methods must also be applied to the analysis of morphogenetic pathways. An overview of past and potential future studies of leaf morphogenesis is presented.
