Plant species diversification entails the action of reproductive barriers, which are severely challenged when related species grow in contact and form hybrid progeny. Orchis italica and O. anthropophora are two related orchid species that produce a known hybrid form, O. xbivonae. Here, we analysed a hybrid zone of these two orchids using molecular analysis and experimental crosses. As molecular tools, we employed both real-time PCR and PCR amplification of nuclear markers to evaluate the… CONTINUE READING
