New locus reveals the genetic architecture of sex reversal in the Chinese tongue sole (Cynoglossus semilaevis)
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 located in the third intron of the doublesex and mab-3 related transcription factor 1 (Dmrt1) gene on the Z chromosome (named Cyn_Z_8564889) and has two alleles, A and G. Cyn_Z_8564889 regulates sex reversal interactively with our previously detected SNP (Cyn_Z_6676874), with the genetic females simultaneously carrying the T allele of Cyn_Z_6676874 and the A allele of Cyn_Z_8564889 changing into pseudomales. Other Dmrt1 polymorphisms were detected, which formed two haplotypes. Two SN...

Differential introgression in a mosaic hybrid zone reveals candidate barrier genes
Hybrid zones act as genomic sieves; although globally advantageous alleles will spread throughout the zone and neutral alleles can be freely exchanged between species, introgression will be restricted for genes that contribute to reproductive barriers or local adaptation. Seminal fluid proteins (SFPs) are known to contribute to reproductive barriers in insects and have been proposed as candidate barrier genes in the hybridizing field crickets G. pennsylvanicus and G. firmus. Here, we have used 125 SNPs to characterize patterns of differential introgression and to identify genes that may contribute to prezygotic barriers between these species. Using a transcriptome scan of the male cricket accessory gland (the site of SFP synthesis), we identified genes with major allele frequency differences between the species. We then compared patterns of introgression for genes encoding seminal fluid proteins with patterns for genes expressed in the same tissue that do not encode SFPs. We find no evi...
