Functional Study of Four Histone Genes Involved in the Spermatogenesis of Cynoglossus semilaevis.

ABSTRACT: Chinese tongue sole (Cynoglossus semilaevis) is an important mariculture fish in China, and female individuals present a growth advantage. However, genetic females (ZW) can sex reverse to phenotypic males, designated pseudomales. The pseudomale shows abnormal spermatogenesis and produces only Z sperm. Histone is pivotal in spermatogenesis, and post-translational modification could regulate its function. A comparison of testis phosphorylated and ubiquitinated proteins revealed 8 and 12 differentially phosphorylated and ubiquitinated histones in the testes of male and pseudomale Chinese tongue soles, respectively, but there was no difference in the translation level of these proteins. We selected four histone genes, h1.1-like, h1.2-like, h3, and h3.3-like,
