化学信号是蜥蜴通讯系统的重要组成部分,表皮腺负责产生调节许多行为相互作用的化学信息素。先前已经描述了蜥蜴的两种类型的表皮腺:滤泡腺和生成腺。一代腺体的特征是上皮中新的腺细胞类型聚集并且缺乏内腔或外部孔。尽管多年来人们已经认识到了世代腺的几种亚型,但新热带分支中世代腺的形态、分类分布、功能和进化起源仍然几乎未被探索。在这里,我们描述了南美 Tropiduridae 蜥蜴的一种新型孔罩型世代腺(“α-腺”),表征了其结构和超微结构组织,并研究了系统发育框架中各组成部分的同源性。 α-腺体出现在欧洲脊龙、皱襞、球座龙、热带龙和乌拉森特龙的祖先中,并且存在于至少 39 个具有不同生态习性的物种中。我们初步分析了α-腺体的蛋白质谱,发现性别之间蛋白质成分的表达差异。我们的研究改变了关于表皮腺同源性的一般观点,使我们认为世代和毛囊腺在功能和进化上的相关性可能比以前认为的更为密切。
Chemical signalling is an essential component of the communication system of lizards, and epidermal glands are responsible for producing semiochemicals that regulate many behavioural interactions. Two types of epidermal glands have been previously described for lizards: follicular and generation glands. Generation glands are characterized by the aggregation of novel glandular cell types in the epithelium and the lack of a lumen or external pore. Despite the fact that several subtypes of generation glands have been recognized over the years, the morphology, taxonomic distribution, function and evolutionary origins of generation glands remain nearly unexplored in Neotropical clades. Here, we describe a novel escutcheon-type generation gland (‘α-gland’) for lizards of the South American family Tropiduridae, characterize its structural and ultrastructural organization, and study the homology of the constituent parts in a phylogenetic framework. The α-glands emerged in the ancestor ofEurolophosaurus,Plica,Strobilurus,TropidurusandUracentron, and are found in at least 39 species with diverse ecological habits. We preliminarily analysed the protein profile of α-glands and discovered differential expression of protein components between sexes. Our investigations change the general view about epidermal gland homology, leading us to argue that generation and follicular glands are possibly more closely related functionally and evolutionarily than previously thought.
