New locus reveals the genetic architecture of sex reversal in the Chinese tongue sole (Cynoglossus semilaevis)

Abstract: Sex reversal in insects, amphibians, reptiles, and fishes is a complicated and interesting biological phenomenon. Sex reversal changes the sex ratio of populations and may complicate breeding schemes. In the Chinese tongue sole (Cynoglossus semilaevis), genetic females may change into pseudomales, thereby increasing aquaculture costs because of the lower growth rate of the males than that of the females. Here we identify a new locus associated with sex reversal; this single nucleotide polymorphism (SNP) is loc… Show more

“…Excitedly, recent studies have uncovered sex determining gene dmrt1 , and new single nucleotide polymorphism (SNP) loci associated with pseudomales, allowing for the detection of male, female, and pseudomale C . semilaevis (Cui et al, 2017; Jiang and Li, 2017; Cui et al, 2018).…”

“…Exosomes from mouse and human seminal fluid have been isolated and analysed, representing an excellent system to study piwi-interacting genes and their regulatory network [21]. Although several different kinds of sex molecular markers have been developed in C. semilaevis, such as amplified fragment-length polymorphism (AFLP) markers [3], co-dominant microsatellite markers [22], single nucleotide polymorphisms (SNPs) [23], and miRNAs markers [24], identifying different types of sex markers is also important to study the sex determination mechanism of this fish. In the present study, we compared the piRNA profiles in exosomes from male and pseudomale seminal plasma to identify the differentially expressed piRNAs.…”

“…Models of sex differentiation in amphibians can be divided into three types: (1) a direct development of the undifferentiated gonads into testes or ovaries, (2) the development of the undifferentiated gonad into the ovary and subsequent development of the testis through the ovary, and (3) the development of the testes through the intersex phase (prodifferentiating type) [17]. For a long time, genes that determine sex could not be found in amphibians.…”
