蛇精子的超微结构受到了广泛的关注,主要是因为蛇在物种之间的生殖特征上表现出相当大的差异,具有广泛的交配系统和生殖行为。蛇种之间精子形态的差异可能与每个分类单元的繁殖策略有关,如竞争或精子储存。我们提供了九种蛇的精子超微结构的详细描述(Aniliusscytale,Tropidophispaucisquamis,BothropsJararaca,桂贝,Dipsasmikanii,Micruruscorallinus,扁豆,Acrochordusjavanicus,和Cylindrophisruffus),并将其与以下分类群的文献中的精子数据进行了比较:Liotyphlopsbeui,网纹聚香菇,特里皮达·科佩西,Anilioswaitii,肌腱内膜,Aspiditesmelanochephalus,BoaConstrictorAmarali,CorallusHortulana,Epicratescenchria,occidentalis,Eryxjayakari,Micruruscorallinus,哈里纳米,额骨小骨,小草,Oxyuranusmicrolepidotus,Alternatus,Bothropsdiporus,Crotalusdurissus,Agkistrodon扭曲,Viperaaspis,博伊加·非正规军,ZamenisSchrenckii,Zamenisscalaris,Cuculatus,Nerodiasipedon,鹅卵石,和Myrrophischinensis。我们在所描述的蛇中的精子超微结构中发现了十二个多态性特征。我们的工作支持对精子形态进行超微结构分析以了解蛇繁殖的重要性,并提供精子来源的形态特征进行系统发育分析。
The ultrastructure of snake sperm has received substantial attention primarily because snakes exhibit considerable variability in reproductive characteristics between species, with a wide range of mating systems and reproductive behaviors. Variability of sperm morphology among snake species may be associated with the reproductive strategies of each taxon, such as competition or sperm storage. We provide a detailed description of the sperm ultrastructure of nine snake species (Anilius scytale, Tropidophis paucisquamis, Bothrops jararaca, Oxyrhopus guibei, Dipsas mikanii, Micrurus corallinus, Xenopholis scalaris, Acrochordus javanicus, and Cylindrophis ruffus) and compared this with sperm data from the literature for the following taxa: Liotyphlops beui, Amerotyphlops reticulatus, Trilepida koppesi, Anilios waitii, Anilios endoterus, Aspidites melanochephalus, Boa constrictor amarali, Corallus hortulana, Epicrates cenchria, Boa constrictor occidentalis, Eryx jayakari, Micrurus corallinus, Micrurus surinamensis, Micrurus frontalis, Micrurus altirostris, Oxyuranus microlepidotus, Bothrops alternatus, Bothrops diporus, Crotalus durissus, Agkistrodon contortrix, Vipera aspis, Boiga irregularis, Zamenis schrenckii, Zamenis scalaris, Stegonotus cuculatus, Nerodia sipedon, Liodytes pygaea, and Myrrophis chinensis. We found twelve polymorphic characters in the ultrastructure of sperm among the described snakes. Our work supports the importance of ultrastructural analysis of sperm morphology to understand snake reproduction, and provides sperm-derived morphological characters for phylogenetic analysis.
