COVER The fractal-like forms of the Romanesco cauliflower are some of the most spectacular in the plant kingdom. These structures arose from the transformation of the cabbage inflorescence during the domestication process. Researchers show how perturbations of the floral gene networks combined with modifications of growth dynamics led to the emergence of such fractal forms. See page 192.
