    • Argentinian potato leafroll virus P0 protein : Novel activities for a previously known suppressor 

      Barrios Baron, Maria Pilar; Delfosse, Veronica Cecilia; Agrofoglio, Yamila Carla; Nahirñak, Vanesa; Almasia, Natalia Ines; Vazquez Rovere, Cecilia; Distefano, Ana Julia (Wiley, 2021-02)
      The potato leafroll virus (PLRV) P0 protein (P0PL) is a suppressor of RNA silencing. In this study, we showed that P0 protein from an Argentinian isolate of PLRV (P0PL‐Ar) has an additional activity not described for other ...
    • First complete genome sequence of potato leafroll virus from Argentina 

      Barrios Baron, Maria Pilar; Agrofoglio, Yamila Carla; Delfosse, Veronica Cecilia; Nahirñak, Vanesa; Gonzalez De Urreta, Martin Salvador; Almasia, Natalia Ines; Vazquez Rovere, Cecilia; Sabio Y Garcia, Julia Veronica (2017-07)
      In this study, we determined for the first time the complete genomic sequence of an Argentinian isolate of Potato leafroll virus (PLRV), the type species of the genus Polerovirus. The isolate sequenced came from a Solanum ...
    • Genome-wide analysis of the snakin/GASA gene family in solanum tuberosum cv. Kennebec 

      Nahirñak, Vanesa; Rivarola, Maximo Lisandro; Gonzalez De Urreta, Martin Salvador; Paniego, Norma Beatriz; Hopp, Horacio Esteban; Almasia, Natalia Ines; Vazquez Rovere, Cecilia (2016-04)
      Snakin/GASA proteins have been involved in different aspects of plant growth and development although their exact role is still intriguing. All of them maintain 12 cysteines of the C-terminus in highly conserved positions ...
    • Isolation and characterization of the tissue and development-specific potato snakin-1 promoter inducible by temperature and wounding 

      Almasia, Natalia Ines; Nahirñak, Vanesa; Hopp, Horacio Esteban; Vazquez Rovere, Cecilia (Pontificia Universidad Catolica de Valparaiso, 2010-09)
      Snakin-1 (StSN1) is a broad-spectrum antimicrobial peptide isolated from Solanum tuberosum. Homologous proteins have been identified in a wide range of species but there is no apparent consensus in the roles they play. A ...
    • Potato Snakin-1 Gene Silencing Affects Cell Division, Primary Metabolism, and Cell Wall Composition 

      Nahirñak, Vanesa; Almasia, Natalia Ines; Fernandez, Paula Virginia; Hopp, Horacio Esteban; Estevez, Jose Manuel; Carrari, Fernando; Vazquez Rovere, Cecilia (American Society of Plant Biologists, 2012-01)
      Snakin-1 (SN1) is an antimicrobial cysteine-rich peptide isolated from potato (Solanum tuberosum) that was classified as a member of the Snakin/Gibberellic Acid Stimulated in Arabidopsis protein family. In this work, a ...
    • Potato snakin‑1: an antimicrobial player of the trade‑off between host defense and development 

      Almasia, Natalia Ines; Nahirñak, Vanesa; Hopp, Horacio Esteban; Vazquez Rovere, Cecilia (Springer, 2020-07)
      Snakin-1 (SN1) from potato is a cysteine-rich antimicrobial peptide with high evolutionary conservation. It has 63 amino acid residues, 12 of which are cysteines capable of forming six disulfide bonds. SN1 localizes in the ...
    • Snakin-1 affects reactive oxygen species and ascorbic acid levels and hormone balance in potato 

      Nahirñak, Vanesa; Rivarola, Maximo Lisandro; Almasia, Natalia Ines; Barrios Baron, María Pilar; Hopp, Horacio Esteban; Vile, Denis; Paniego, Norma Beatriz; Vazquez Rovere, Cecilia (PLOS, 2019-03-25)
      Snakin-1 is a member of the Solanum tuberosum Snakin/GASA family. We previously demonstrated that Snakin-1 is involved in plant defense to pathogens as well as in plant growth and development, but its mechanism of action ...
    • Snakin/GASA proteins : involvement in hormone crosstalk and redox homeostasis 

      Nahirñak, Vanesa; Almasia, Natalia Ines; Hopp, Horacio Esteban; Vazquez Rovere, Cecilia (Taylor & Francis, 2012)
      Snakin/GASA proteins are widely distributed among plant species. They are expressed in different plant organs with high tissue and temporal specificity, and their subcellular localization varies among the different members. ...
    • State of the art of genetic engineering in potato: from the first report to its future potential
