    • Moscas minadoras del girasol y sus enemigos naturales 

      Valladares, Graciela Rosa; Salvo, Silvia Adriana; Saini, Esteban Daniel (Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-08)
      Las “moscas minadoras” se caracterizan por excavar túneles (“minas”) en el interior de las hojas, consumiendo el mesófilo y dejando intacta la epidermis foliar o, al menos, su pared externa. Hay especies cuyas larvas, en ...

    • Nuevas estrategias para la transformación y expresión de genes de interés en girasol 

      Radonic, Laura Mabel (Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2011-09)
      El girasol es una especie de la familia Asteraceae (Compositae) de gran importancia económica, considerada hasta hace una década recalcitrante al cultivo in vitro y la transformación genética. En un trabajo previo (Radonic, ...

    • Peculiarities of the Transformation of Asteraceae Family Species: The Cases of Sunflower and Lettuce 

      Darqui, Flavia Soledad; Radonic, Laura Mabel; Beracochea, Valeria Cecilia; Hopp, Horacio Esteban; Lopez Bilbao, Marisa Gisela (Frontiers Publishing, 2021-11)
      The Asteraceae family is the largest and most diversified family of the Angiosperms, characterized by the presence of numerous clustered inflorescences, which have the appearance of a single compound flower. It is estimated ...

    • Phylodynamics of sunflower chlorotic mottle virus, an emerging pathosystem 

      Cabrera Mederos, Dariel; Torres, Carolina; Bejerman, Nicolas Esteban; Trucco, Veronica Milagros; Lenardon, Sergio Luis; Leiva Mora, Michel; Giolitti, Fabian (Elsevier, 2020-03-12)
      Distribution and epidemiological patterns of sunflower chlorotic mottle virus (SCMoV) in sunflower (Helianthus annuus L.) growing areas in Argentina were studied from 2006 to 2017. The virus was detected exclusively in ...

    • Plasticity in sunflower leaf and cell growth under high salinity 

      Céccoli, Gabriel; Bustos, Dolores Angela; Ortega, Leandro Ismael; Senn, Eugenia; Vegetti, Abelardo Carlos; Taleisnik, Edith (Wiley, 2015-01)
      A group of sunflower lines that exhibit a range of leaf Na+ concentrations under high salinity was used to explore whether the responses to the osmotic and ionic components of salinity can be distinguished in leaf expansion ...

    • Sequencing of two Sunflower chlorotic mottle virus isolates obtained from different natural hosts shed light on its evolutionary history 

      Bejerman, Nicolas Esteban; Giolitti, Fabian; De Breuil, Soledad; Lenardon, Sergio Luis (Springer, 2013-02)
      Sunflower chlorotic mottle virus (SuCMoV), the most prevalent virus of sunflower in Argentina, was reported naturally infecting not only sunflower but also weeds. To understand SuCMoV evolution and improve the knowledge ...

    • The chlorotic symptom induced by Sunflower chlorotic mottle virus is associated with changes in redox-related gene expression and metabolites 

      Rodriguez, Marianela; Muñoz, Nacira Belen; Lenardon, Sergio Luis; Lascano, Hernan Ramiro (Elsevier, 2012-08-18)
      Systemic infections are commonly associated with changes in host metabolism and gene expression. Sunflower chlorotic mottle virus (SuCMoV) causes systemic infection with sugar increase, photoinhibition and increase in ...

    • Unveiling the genetic basis of Sclerotinia head rot resistance in sunflower 

      Filippi, Carla Valeria; Zubrzycki, Jeremias Enrique; Di Rienzo, Julio Alejandro; Quiroz, Facundo Jose; Puebla, Andrea Fabiana; Alvarez, Daniel; Maringolo, Carla Andrea; Escande, Alberto; Hopp, Horacio Esteban; Heinz, Ruth Amelia; Paniego, Norma Beatriz; Lia, Veronica Viviana (BMC, 2020-07)
      Background: Sclerotinia sclerotiorum is a necrotrophic fungus that causes Sclerotinia head rot (SHR) in sunflower, with epidemics leading to severe yield losses. In this work, we present an association mapping (AM) approach ...

    • Weather-based predictive models for Diaporthe helianthi ascospore release in Uruguay 

      Moschini, Ricardo Carlos; Rodríguez, M.J; Martinez, Malvina Irene; Stewart, S. (Springer, 2019-08-01)
      Stem canker (SC), caused by Diaporthe helianthi, is the most serious sunflower disease in Uruguay. Yield losses have been estimated up to 75%. Chemical control is one of the strategies used to manage this disease, but ...
