Role of Sex-Concordant Gene Expression in the Coevolution of Exaggerated Male and Female Genitalia in a Beetle Group.

ABSTRACT: Some sexual traits, including genitalia, have undergone coevolutionary diversification toward exaggerated states in both sexes among closely related species, but the underlying genetic mechanisms that allow correlated character evolution between the sexes are poorly understood. Here, we studied interspecific differences in gene expression timing profiles involved in the correlated evolution of corresponding male and female genital parts in three species of ground beetle in Carabus (Ohomopterus). The male and female genital parts maintain morphological matching, whereas large interspecific variation in genital part size has occurred in the genital coevolution between the sexes toward exaggeration. We analyzed differences in gene expression involved in the interspecific differences in genita
