A mechanism for red coloration in vertebrates
Toomey, Matthew B.; Marques, Cristiana I.; Araújo, Pedro M.; Huang, Delai; Zhong, Siqiong; Liu, Yu; Schreiner, Gretchen D.; Myers, Connie A.Red coloration is a salient feature of the natural world. Many vertebrates produce red color by converting dietary yellow carotenoids into red ketocarotenoids via an unknown mechanism. Here, we show that two enzymes, cytochrome P450 2J19 (CYP2J19) and 3-hydroxybutyrate dehydrogenase 1-like (BDH1L), are sufficient to catalyze this conversion. In birds, both enzymes are expressed at the sites of ketocarotenoid bi...
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 M.Grapevine (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 ...
