• A tomato tocopherol-binding protein sheds light on intracellular a-tocopherol metabolism in plants 

      Bermudez Salazar, Luisa; del Pozo, Talía; Lira, Bruno Silvestre; Godoy, Fabiana de; Boos, Irene; Romano, Cecilia; Previtali, Viola; Almeida, Juliana; Brehelin, Claire; Asis, Ramón; Quadrana, Leandro Daniel; Demarco, Diego; Alseekh, Saleh; Salinas Gamboa, Rigel; Perez-Flores, Laura; Dominguez, Pia Guadalupe; Rothan, Christophe; Fernie, Alisdair R.; Gonzalez, Maurıcio; Stocker, Achim; Hemmerle, Andreas; Clausen, Mads Hartving; Carrari, Fernando; Rossi, Magdalena (Oxford University Press, 2018-11)
      Tocopherols are non-polar compounds synthesized in the plastids, which function as major antioxidants of the plant cells and are essential in the human diet. Both the intermediates and final products of the tocopherol ...
    • Allelic differences in a vacuolar invertase affect Arabidopsis growth at early plant development 

      Coluccio Leskow, Carla; Dominguez, Pia Guadalupe; Díaz Zirpolo, José Antonio; Obata, Toshihiro; Kamenetzky, Laura; Costa, Hernán; Taboga, Oscar Alberto; Marti, Hector Ruben; Keurentjes, Joost; Sulpice, Ronan; Ishihara, Hirofumi; Stitt, Mark; Fernie, Alisdair R.; Carrari, Fernando (2016)
      Improving carbon fixation in order to enhance crop yield is a major goal in plant sciences. By quantitative trait locus (QTL) mapping, it has been demonstrated that a vacuolar invertase (vac-Inv) plays a key role in ...
    • ASR1 transcription factor and its role in metabolism 

      Dominguez, Pia Guadalupe; Carrari, Fernando (Taylor & Francis, 2015-03)
      Asr1 (ABA, stress, ripening) is a plant gene widely distributed in many species which was discovered by differential induction levels in tomato plants subjected to drought stress conditions. ASR1 also regulates the expression ...
    • Genome-wide data (ChIP-seq) enabled identification of cell wall-related and aquaporin genes as targets of tomato ASR1, a drought stress-responsive transcription factor 

      Ricardi, Martiniano María; González, Rodrigo Matías; Silin, Zhong; Dominguez, Pia Guadalupe; Duffy, Tomas; Turjanski, Pablo Guillermo; Salgado Salter, Juan David; Alleva, Karina Edith; Carrari, Fernando; Giovannoni, James J.; Estevez, Jose Manuel; Iusem, Norberto Daniel (BMC, 2014-01)
      Background: Identifying the target genes of transcription factors is important for unraveling regulatory networks in all types of organisms. Our interest was precisely to uncover the spectrum of loci regulated by a widespread ...
    • Multiomics analyses reveal the roles of the ASR1 transcription factor in tomato fruits 

      Dominguez, Pia Guadalupe; Conti, Gabriela; Duffy, Tomas; Insani, Ester Marina; Alseekh, Saleh; Asurmendi, Sebastian; Fernie, Alisdair R.; Carrari, Fernando (Oxford University Press, 2021-09)
      The transcription factor ASR1 (ABA, STRESS, RIPENING 1) plays multiple roles in plant responses to abiotic stresses as well as being involved in the regulation of central metabolism in several plant species. However, despite ...
    • Natural occurring epialleles determine vitamin E accumulation in tomato fruits 

      Quadrana, Leandro Daniel; Almeida de Souza, Juliana Beatriz; Asis, Ramón; Duffy, Tomas; Dominguez, Pia Guadalupe; Bermudez Salazar, Luisa; Conti, Gabriela; Silva, Junia V. Corrêa da; Peralta, Iris Edith; Colot, Vincent; Asurmendi, Sebastian; Fernie, Alisdair R.; Rossi, Magdalena; Carrari, Fernando Oscar (2014-07)
      Vitamin E (VTE) content is a low heritability nutritional trait for which the genetic determinants are poorly understood. Here, we focus on a previously detected major tomato VTE quantitative trait loci (QTL; mQTL9-2-6) ...
    • Tomato Abscisic Acid Stress ripening (ASR) gene family revisited 

      Golan, Ido; Dominguez, Pia Guadalupe; Konrad, Zvia; Shkolnik Inbar, Doron; Carrari, Fernando; Bar Zvi, Dudy (PLOS, 2014-10-13)
      Tomato ABSCISIC ACID RIPENING 1 (ASR1) was the first cloned plant ASR gene. ASR orthologs were then cloned from a large number of monocot, dicot and gymnosperm plants, where they are mostly involved in response to abiotic ...
