Background: Reproductive proteins often evolve rapidly and are thought
to be subject to strong sexual selection, and thus may play a key role in
reproductive isolation and species divergence. However, our knowledge of reproductive
proteins has been largely limited to males and model organisms with sequenced
genomes. With advances in ... read moresequencing technology, Lepidoptera are emerging models for
studies of sexual selection and speciation. By profiling the transcriptomes of the
bursa copulatrix and bursal gland from females of two incipient species of moth, we
characterize reproductive genes expressed in the primary reproductive tissues of
female Lepidoptera and identify candidate genes contributing to a one-way gametic
incompatibility between Z and E strains of the European corn borer (Ostrinia
nubilalis).
Keywords: Female reproductive genes, Speciation, Next-generation
sequencing, Lepidoptera.
