Protein fractions of salivary glands were analyzed from 30 wildtype strains of eight species belonging to the Drosophila nasuta subgroup by SDS-polyacrylamide gel electrophoresis. The electrophoretic patterns indicated several prominent bands which could be shown to represent the major glue protein fractions. The glue protein fractions are species-specific as well as wildtype strain-specific. Wildtype strain specificities are characterized by variations of the species-specific patterns. The patterns of the different wildtypes, species, and hybrids were used for taxonomic identification within the nasuta subgroup, in which the females are morphologically indistinguishable and the males differ only by the markings of their frons. The hybrids provide evidence for gonosomal as well as autosomal linkage of individual genes coding for the major glue protein fractions.
通过SDS-聚丙烯酰胺凝胶电泳对果蝇纳苏塔亚组八个物种的30个野生型菌株的唾液腺蛋白质组分进行了分析。电泳图谱显示出几条明显的条带，这些条带可被证明代表主要的胶水蛋白组分。胶水蛋白组分具有物种特异性以及野生型菌株特异性。野生型菌株特异性的特征在于物种特异性模式的变化。不同野生型、物种和杂种的模式被用于纳苏塔亚组内的分类鉴定，在该亚组中，雌性在形态上无法区分，雄性仅在前额的斑纹上有所不同。杂种为编码主要胶水蛋白组分的单个基因的性染色体以及常染色体连锁提供了证据。
