How the dragon got its 'snap'
Date:11/9/2010

hemical compass that allows it to get its bearings within the tissue, giving it the information needed to grow more in some directions than others. Genes also influence the cell's equivalent of magnetic poles; key regions of tissue that chemical compasses point to. Publishing in the journal PLoS Biology, the researchers show how these principles allow very complex biological shapes to generate themselves.

"We are now trying to get a better understanding of exactly how the chemical compasses work and determining the molecular nature of the poles that coordinate their orientations," said Professor Enrico Coen of the John Innes Centre.

The study also throws light on how different shapes may evolve. In the computational model, small changes to the genes that influence the growth rules produce a variety of different forms. The shape of the snapdragon flower, with the closely matched upper and lower petal shapes, could have arisen through similar 'genetic tinkering' during evolution. Evolutionary tinkering could also underlie the co-ordinated changes required for the development of many other biological structures, such as the matched upper and lower jaws of vertebrates.
