Making Waves for Segments.

The article cites a report within the issue regarding research investigating the role of gene expression in segmentation by A. F. Sarrazin and colleagues. Topics include oscillating gene expression in vertebrate segmentation, which occurs sequentially within a posterior growth zone, evidence of cyclic expression during arthropod segmentation in the beetle Tribolium castaneum and the fruit fly Drosophila melanogaster, and a diagram illustrating oscillating gene expression in the transcription factor odd-skipped (odd) in the Tribolium beetle.
