Abstract

The morphogen gradient as a source of embryonic patterning is one of the best accepted concepts in developmental biology. Morphogens can be transcription factors or extracellular signals, but in both cases, they are thought to provide concentration thresholds that position different cell fates within the developing embryo. Several recent papers examine the patterning activities of Drosophila Bicoid, the first known molecular morphogen and reach different conclusions about the patterning power of a single morphogen gradient.
