About the Cover


Chemosensory cells and bristles along the edge of the Drosophila wing are marked by a pseudocolored green fluorescent protein signal, driven from the promoter of the circadian clock gene period. These cells support independent photoreceptive clocks; multiple tissues (including the wing) throughout the animal display circadian rhythms in culture. See page 1632 and the related News story on page 1560. [Image: Jeffrey Plautz, Steve Kay, Cynthia Faber Smith]
