Molecular parallelisms between pigmentation in the avian iris and the integumen...
Andrade, Pedro; Gazda, Małgorzata A; Araújo, Pedro M.; Afonso, Sandra; Rasmussen, Jacob A.; Marques, Cristiana I.; Lopes, Ricardo J.Birds exhibit striking variation in eye color that arises from interactions between specialized pigment cells named chromatophores. The types of chromatophores present in the avian iris are lacking from the integument of birds or mammals, but are remarkably similar to those found in the skin of ectothermic vertebrates. To investigate molecular mechanisms associated with eye coloration in birds, we took advantag...
Pervasive hybridization with local wild relatives in Western European grapevine...
Freitas, Sara; Gazda, Małgorzata A; Rebelo, Miguel Â; Muñoz-Pajares, Antonio J; Vila-Viçosa, Carlos; Muñoz-Mérida, Antonio; Gonçalves, Luís MGrapevine (Vitis vinifera L.) diversity richness results from a complex domestication history over multiple historical periods. Here, we used whole-genome resequencing to elucidate different aspects of its recent evolutionary history. Our results support a model in which a central domestication event in grapevine was followed by postdomestication hybridization with local wild genotypes, leading to the presence ...
