- Evolutionary Characteristics of the Protamine-Like Protein (PLI) Gene Family in Syngnathidae Fishes and Its Potential Regulatory Role in Sperm Morphological Specialization. Peng, Xiaoqian Xiao, Wanghong Wang, Yaqi Liu, Jinfeng Zhang, Jiani Yang, Jingwen Qin, Geng Lin, Qiang Animals Male Protamines Evolution, Molecular Spermatozoa Fish Proteins Phylogeny Smegmamorpha Multigene Family Sperm Head Sperm Proteins Spermatogenesis Testis Syngnathidae fishes possess an elongated sperm morphology that is adapted for fertilization within the brood pouch. Protamine-like proteins (PLs) present a class of DNA-binding proteins that replace histones and bind to DNA during the late stages of vertebrate spermatogenesis, promoting chromatin condensation into compact sperm nuclei. To verify the correlation between the specialized sperm morphology of Syngnathidae fishes and PLI (PL Type I) gene family evolution, this study analyzed sperm morphology in 61 teleost species and revealed that Syngnathidae fishes have relatively elongated sperm heads (head length/diameter, p
