We have analysed the role of the achaete-scute gene complex in the development of the pattern of campaniform sensilla on the wing blade of Drosophila. We show that the complete pattern results from the superimposition of two independent subpatterns, one of which depends on the achaete gene and the other on scute. The scute subpattern comprises several clusters of sensilla, most of which seem to require the presence of control regions located upstream of the transcribed region. This is in contrast with the pattern of scute-dependent bristles, most of which depends on control elements located downstream of the transcribed region.
我们分析了achaete-scute基因复合体在果蝇翅叶片钟形感器模式发育中的作用。我们表明，完整的模式是由两个独立的子模式叠加而成的，其中一个子模式依赖于achaete基因，另一个依赖于scute基因。scute子模式包括几个感器簇，其中大多数似乎需要转录区域上游控制区的存在。这与依赖scute的刚毛模式形成对比，后者大多数依赖于转录区域下游的控制元件。
