The plant developmental regulator GNOM performs its unique function from the cell periphery, through sequence features present in all its domains, and not by the control of endocytosis.

mille-pattes micropeptides have conserved function in insect embryonic patterning together with transcription factor Shaven-baby and ubiquitin ligase Ubr3, except in flies wherein restoring broad embryonic Svb expression restores patterning potency.

Lefty-mediated feedback inhibition of Nodal signaling mitigates signaling perturbations, but is dispensable for development.

Wings achieve plasticity in size while maintaining robust pattern via ecdysone, which elicits graded responses for growth rates and threshold responses for patterning rates, in the fruit fly Drosophila melanogaster.

In contrast to growing evidence that juxtracrine signalling accounts for Wnt/Wingless patterning function, Wingless behaves as a released signal in Drosophila renal tubule development, being secreted from the midgut to spread and pattern the proximal tubule.

A stochastic model of phyllotaxis can explain the striking irregularities observed in the spiral patterns of plants and predicts that perturbation patterns provide key information about the underlying biochemical mechanisms.

Zebrafish scales depend on interactions among Wnt, Ectodysplasin and Hedgehog signaling pathways similar to those underlying feathers, teeth and hair follicles, suggesting a deep homology of ectodermal appendages in vertebrates.

About twenty temporal patterning genes are identified that drive an irreversible differentiation trajectory governing the heterogeneity and proliferative properties of cells in neural tumors with an early developmental origin.

In stau^-mutants, the Hunchback boundary shifts posteriorly by 10% EL but shows comparable variability to that of the wild type in short time windows in nuclear cycle 14.

The spectacular frill around the neck of the lizard Chlamydosaurus has its origins in a mechanical instability that arises during development.
