    • Carotenoid-enriched transgenic corn delivers bioavailable carotenoids to poultry and protects them against coccidiosis 

      Nogareda, Carmina; Moreno, José A.; Angulo Asensio, Eduardo; Sandmann, Gerhard; Portero Otín, Manuel; Capell Capell, Teresa; Zhu, Changfu; Christou, Paul (John Wiley & SonsWiley-Blackwell, 2015)
      Carotenoids are health-promoting organic molecules that act as antioxidants and essential nutrients. We show that chickens raised on a diet enriched with an engineered corn variety containing very high levels of four key ...
    • Carotenoid-enriched Transgenid Corn in Poultry Nutrition 

      Díaz Gómez, Joana; Moreno Martínez, José Antonio; Angulo Asensio, Eduardo; Sandmann, Gerhard; Portero Otín, Manuel; Capell Capell, Teresa; Zhu, Changfu; Christou, Paul; Nogareda, Carmina (Virginia Polytechnic Institute and State University, 2015-05-01)
      Vitamin A deficiency (VAD) is one of the most important micronutrient deficiencies globally. It is prevalent throughout the world, but it is particularly severe in Africa and South-East Asia. The main underlying cause of ...
    • High-carotenoid biofortified maize is an alternative to color additives in poultry feed 

      Díaz Gómez, Joana; Moreno Martínez, José Antonio; Angulo Asensio, Eduardo; Sandmann, Gerhard; Zhu, Changfu; Ramos Girona, Antonio J.; Capell Capell, Teresa; Christou, Paul; Nogareda, Carmina (Elsevier B.V., 2017-06-12)
      Skin color in poultry is achieved by the addition of natural or synthetic pigments to feed. Crops used routinely in feed formulations offer an alternative cost-effective strategy to replace color additives if they are ...
    • High-carotenoid maize: development of plant biotechnology prototypes for human and animal health and nutrition 

      Zhu, Changfu; Farré Martinez, Gemma; Zanga, Daniela; Lloveras Vilamanyà, Jaume; Michelena Bárcena, Antonio; Ferrio Díaz, Juan Pedro; Voltas Velasco, Jordi; Slafer, Gustavo A.; Savin, Roxana; Albajes Garcia, Ramon; Eizaguirre Altuna, Matilde; López Alonso, Carmen; Cantero-Martínez, Carlos; Díaz Gómez, Joana; Nogareda, Carmina; Moreno Martínez, José Antonio; Angulo Asensio, Eduardo; Estany Illa, Joan; Pena i Subirà, Ramona Natacha; Tor i Naudí, Marc; Portero Otín, Manuel; Eritja Sánchez, Núria; Arjó Pont, Gemma; Serrano Casasola, José Carlos Enrique; Matias-Guiu, Xavier; Twyman, Richard M.; Sandmann, Gerhard; Capell Capell, Teresa; Christou, Paul (Springer Verlag, 2017-06-01)
      Carolight® is a transgenic maize variety that accumulates extraordinary levels of carotenoids, including those with vitamin A activity. The development of Carolight® maize involved the technical implementation of a novel ...
    • Provitamin A carotenoids from an engineered high-carotenoid maize are bioavailable and zeaxanthin does not compromise β-carotene absorption in poultry 

      Díaz Gómez, Joana; Moreno Martínez, José Antonio; Angulo Asensio, Eduardo; Sandmann, Gerhard; Zhu, Changfu; Capell Capell, Teresa; Nogareda, Carmina (Springer International Publishing, 2017)
      High-carotenoid (HC) maize, a biofortified staple crop which accumulates β-carotene, β-cryptoxanthin, lutein and zeaxanthin, was used as a feed component in a chicken feeding trial to assess the bioavailability of provitamin ...
    • The distribution of carotenoids in hens fed on biofortified maize is influenced by feed composition, absorption, resource allocation and storage 

      Moreno Martínez, José Antonio; Díaz-Gómez, J.; Nogareda, Carmina; Angulo Asensio, Eduardo; Sandmann, Gerhard; Portero Otín, Manuel; Serrano Casasola, José Carlos Enrique; Twyman, Richard M.; Capell Capell, Teresa; Zhu, Changfu; Christou, Paul (Nature, 2016)
      Carotenoids are important dietary nutrients with health-promoting effects. The biofortification of staple foods with carotenoids provides an efficient delivery strategy but little is known about the fate and distribution ...
    • ZmPBF and ZmGAMYB transcription factors independently transactivate the promoter of the maize (Zea mays L.) β-carotene hydroxylase 2 gene 

      Jin, Xin; Bai, Chao; Bassie Rene, Ludovic; Nogareda, Carmina; Romagosa Clariana, Ignacio; Twyman, Richard M.; Christou, Paul; Zhu, Changfu (Wiley, 2018-12-01)
      The maize (Zea mays) enzyme b-carotene hydroxylase 2 (ZmBCH2) controls key steps in the conversion of b-carotene to zeaxanthin in the endosperm. The ZmBCH2 gene has an endosperm-preferred and developmentally regulated ...
