    • 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 ...

    • Caracterización molecular de mutantes derivadas del genotipo mutador de cloroplastos de cebada 

      Colombo, Noemi (Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2008)
      La coordinación de la expresión génica entre los genomas nuclear, plastídico y mitocondrial es de importancia crucial para las células vegetales. Un caso particular de la interacción núcleo-plástido está dado por los genes ...

    • Chloroplast and mitochondrial genomes of tomato 

      Lichtenstein, Gabriel; Conte, Mariana; Asis, Ramón; Carrari, Fernando (2016)
      This chapter summarizes the main features of the tomato plastid and mitochondrial genomes in the context of the current knowledge about “orthologue” genomes from other higher plants species in a historical perspective. ...

    • Estudio de la variabilidad genética inducida por el genotipo mutador de cloroplastos de la cebada a través de la técnica de TILLING 

      Lencina, Franco (Departamento de Fisiología, Biología Molecular y Celular, Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2018-11)
      El aislamiento de mutantes inducidas en el plastoma a partir de tratamientos con mutágenos químicos y/o físicos es muy poco exitoso. El genotipo mutador de los cloroplastos de la cebada (cpm) es único en monocotiledóneas ...

    • Phytochrome-dependent temperature perception modulates isoprenoid metabolism 

      Bianchetti, Ricardo; De Luca, Belen; De Haro, Luis Alejandro; Rosado, Daniele; Demarco, Diego; Conte, Mariana; Bermudez Salazar, Luisa; Freschi, Luciano; Fernie, Alisdair R.; Michaelson, Louise V.; Haslam, Richard P.; Rossi, Magdalena; Carrari, Fernando (American Society of Plant Biologists, 2020-07)
      Changes in environmental temperature influence many aspects of plant metabolism; however, the underlying regulatory mechanisms remain poorly understood. In addition to their role in light perception, phytochromes (PHYs) ...

    • Plastome mutations and recombination events in barley chloroplast mutator seedlings 

      Landau, Alejandra Mabel; Lencina, Franco; Pacheco, Maria Gabriela; Prina, Alberto Raul (2016)
      The barley chloroplast mutator (cpm) is an allele of a nuclear gene that when homozygous induces several types of cytoplasmically inherited chlorophyll deficiencies. In this work, a plastome Targeting Induced Local Lesions ...

    • The rpl23 gene and pseudogene are hotspots of illegitimate recombination in barley chloroplast mutator seedlings 

      Lencina, Franco; Landau, Alejandra Mabel; Petterson, Maria Elizabeth; Pacheco, Maria Gabriela; Kobayashi, K.; Prina, Alberto Raul (Nature Publishing Group, 2019-07)
      Previously, through a TILLING (Targeting Induced Local Lesions in Genomes) approach applied on barley chloroplast mutator (cpm) seedlings a high frequency of polymorphisms in the rpl23 gene was detected. All the polymorphisms ...

    • Silencing of the tomato Sugar Partitioning Affecting protein (SPA) modifies sink strength through a shift in leaf sugar metabolism 

      Bermudez Salazar, Luisa; de Godoy, Fabiana; Baldet, Pierre; Demarco, Diego; Osorio, Sonia; Quadrana, Leandro Daniel; Almeida de Souza, Juliana Beatriz; Asis, Ramón; Gibon, Yves; Fernie, Alisdair R.; Rossi, Maria Magdalena; Carrari, Fernando (Wiley; Society for Experimental Biology, 2014-03)
      Limitations in our understanding about the mechanisms that underlie source-sink assimilate partitioning are increasingly becoming a major hurdle for crop yield enhancement via metabolic engineering. By means of a ...

    • The barley chloroplast mutator (cpm) mutant: all roads lead to the Msh1 gene 

      Lencina, Franco Daniel; Landau, Alejandra Mabel; Prina, Alberto Raul (MDPI, 2022-02)
      The barley chloroplast mutator (cpm) is a nuclear gene mutant that induces a wide spectrum of cytoplasmically inherited chlorophyll deficiencies. Plastome instability of cpm seedlings was determined by identification of a ...
