Abstract: Abstract: The molecular and cellular characteristics of male germ cell development remain largely unknown in corals. This study focused on the expression pattern of acetylated α-tubulin (Ac-α-Tu), which is involved in male germ cell development in various animals across taxa, to gain a better understanding of male germ cell development in the stony coral Euphyllia ancora. Immunohistochemical analysis of the different stages of male germ cells showed the presence of filamentous Ac-α-Tu in the early to late stages of male germ cells-such as spermatogonia, spermatocytes, and spermatids-as well as in the flagella of mature sperm. Immunocytochemical and transmission electron microscope analyses demonstrated that early-stage male germ cells possess long flagella containing Ac-α-Tu. The presence of filamentous Ac-α-Tu was also immunohistochemically demonstrated in the male germ cells from 14 other coral species, implying that possession of flagella with Ac-α-Tu is a common characteristic of male germ cells in stony corals. Therefore, as a distinctive cellular characteristic of male germ cells, Ac-α-Tu could be used as a male germ cell marker in stony corals; indeed, immunolabeling for Ac-α-Tu may be a useful method to aid in the identification and morphological observation of male germ cells in various corals in basic and applied biology (e.g., aquaculture) as well as in ecological studies.
