    Carrillo, Natalia; Piccoli, Patricia; Bottini, Rubén; Rodríguez, José; Berli, Federico (Comité editorial Australian Journal of Grape and Wine Research, 2020-02-17)
    ARTÍCULO PUBLICADO EN REVISTA EXTERNA. Background and Aims Some grapevine cultivars such as Malbec have unstable yield, due to poor fruitset or fruitlet abscission. The phenomenon is known as ‘shatter’ and this study aims to explore the potential of applying the shoot girdling technique at flowering, to direct the carbohydrate partitioning towards inflorescences and reduce shatter. Methods and Results Fruitful Malbec shoots were girdled above the apical bunch, below the basal bunch, double girdled or not girdled (Control) during 2017 and 2018. Most vegetative growth parameters were unaffected, ...

  • Changes in grapevine DNA methylation and polyphenols content induced by solar ultraviolet- B radiation, water deficit and abscisic acid spray treatments. 

    Marfil, Carlos; Ibañez, Verónica; Alonso, Rodrigo; Varela, Anabella; Bottini, Rubén; Masuelli, Ricardo; Fontana, Ariel; Berli, Federico (Comité Editorial Plant Physiology and Biochemistry., 2019-02)
    ARTÍCULO PUBLICADO EN REVISTA EXTERNA. Environment and crop management shape plant's phenotype. Argentinean highaltitude vineyards are characterized by elevated solar ultraviolet-B radiation (UV B) and water deficit (D) that enhance enological quality for red winemaking. These signals promote phenolics accumulation in leaves and berries, being the responses mediated by abscisic acid (ABA). DNA methylation is an epigenetic mechanism that regulates gene expression and may affect grapevine growth, development and acclimation, since methylation patterns are mitotically heritable. Berry skins low ...
  • Carotenoid pro!le produced by Bacillus licheniformis Rt4M10 isolated from grapevines grown in high altitude and their antioxidant activity. 

    Cohen, Ana; Dichiara, Elisa; Jofré, Viviana; Antoniolli, Andrea; Bottini, Rubén; Piccoli, Patricia (Editorial International Journal of Food Science + Technology, 2018-07-11)
    ARTÍCULO PUBLICADO EN REVISTA EXTERNA. Bacillus licheniformis (BL ) strains are used for industrial production of exoenzymes, antibiotics and secondary metabolites, and also serve as probiotics. Some strains sequester heavy metals, promoting plant growth or inducing plant systemic resistance against stresses. However, investigations on the biological functions and applicability of carotenoids produced by BL had been less studied. In this study, the carotenoid pro!le produced by BL Rt4M10 was characterised during the accumulation period of culture and in response to diphenylamine (DPA ), inhibitor ...
