Genetic, morphometric, and molecular analyses of interspecies differences in head shape and hybrid developmental defects in the wasp genus Nasonia

Abstract: Males in the parasitoid wasp genus Nasonia have distinct, species-specific, head shapes. The availability of fertile hybrids among the species, along with obligate haploidy of males, facilitates analysis of complex gene interactions in development and evolution. Previous analyses showed that both the divergence in head shape between N. vitripennis and N. giraulti, and the head-specific developmental defects of F2 haploid hybrid males, are governed by multiple changes in networks of interacting genes. Here we e… Show more

“…8b ). It was previously shown that dsx is responsible for male head patterning and eye size in the genus Nasonia 18 , while we showed that glu has no influence on eye size in N.vitripennis . Furthermore, we demonstrated by examining the evolution and the function of the ZnF motif that the role of this domain for sex-specific eye differentiation newly evolved after the gain of sex-specific expression.…”

“…This study in N. vitripennis was informative in that respect, since Nv - glu may represent a possible intermediate evolutionary state of the past, in which sex-specific splicing was gained while a CCHH ZnF motif was still absent. Additionally, the interocular distance of males and females was previously shown to be sexually dimorph in N .vitripennis 18 . The width, length and intraocular distances of the compound eyes did not differ between Nv-glu knockdown and control individuals, in both females and males (Fig.…”

“…The centromere drive hypothesis provides a compelling model for rapid evolution of DNA–protein interactions associated with segregation (Henikoff et al, 2001; Malik & Henikoff, 2009), and perhaps an analogous process might underlie divergence associated with dosage compensation mechanisms in some taxa. Broadly, the evolutionarily dynamic nature of environmental sex determination, sex chromosome systems, and sex determination loci may often be especially conducive to linking problems in speciation to problems in sexual development (Cohen et al, 2021; Dufresnes & Crochet, 2022; Irwin, 2018; Stöck et al, 2021; Valenzuela, 2008).…”
