Delila(Del)基因调控金鱼草中红色花青素的着色模式。我们描述了利用转座子标签克隆del基因的过程，结果表明，该基因编码的蛋白质与调节玉米色素形成的R基因家族的产物具有广泛的同源性。这表明，尽管玉米和金鱼草在形态和着色方面存在许多差异，但对着色模式的控制是由共同的调节因子介导的。Del和R产物含有一个类似于转录因子螺旋-环-螺旋家族保守结构域的区域。原位杂交和RNA分析表明，del的表达与花色苷在花中的分布有关。我们讨论了这些发现对监管网络演变的影响。
The delila (del) gene regulates the pattern of red anthocyanin pigmentation in Antirrhinum majus plants. We describe the cloning of the del locus by transposon tagging and show that it encodes a protein with extensive homology to products of the R gene family, which regulates pigmentation in maize. This shows that in spite of the many differences in morphology and coloration between maize and Antirrhinum, the control of pigmentation pattern is mediated by a common regulator. The del and R products contain a region similar to the conserved domain of the helix-loop-helix family of transcription factors. In situ hybridization and RNA analysis show that the expression of del correlates with the distribution of anthocyanins in the flowers. We discuss the implications of these findings for the evolution of regulatory networks.
