Developmental biologists seek to explain the generation of complex three-dimensional organisms from the starting point of a single cell and its genetic complement. During this incredible transformation, different cell fates rarely are specified intrinsically; rather, the fates of individual cells or groups of cells usually are under the control of external signals that are conserved and recycled throughout the development of the organism. Therefore, developmental mechanisms commonly involve cell-to-cell communication, using signals from neighboring cells or from distant tissues. Elegant mosaic analysis studies show us that many developmental genes act nonautonomously, indicating that they feed into pathways for intercellular signaling. For example, genes involved in leaf patterning (Harper and Freeling, 1996), in the floral transition (Colasanti et al., 1998), and in the homeotic control of flower development (Perbal et al., 1996; Jenik and Irish, 2001) act nonautonomously.
