    • Alfalfa snakin-1 prevents fungal colonization and probably coevolved with rhizobia 

      Garcia, Araceli Nora; Ayub, Nicolás Daniel; Fox, Ana Romina; Gomez, Maria Cristina; Dieguez, Maria Jose; Pagano, Elba Maria; Berini, Carolina Andrea; Muschietti, Jorge Prometeo; Soto, Gabriela Cinthia (BMC Plant Biology, 2014-09-17)
      Background: The production of antimicrobial peptides is a common defense strategy of living cells against a wide range of pathogens. Plant snakin peptides inhibit bacterial and fungal growth at extremely low concentrations. ...
    • Exploring the ancestral mechanisms of regulation of horizontally acquired nitrogenases 

      Pascuan, Cecilia Gabriela; Fox, Ana Romina; Soto, Gabriela Cinthia; Ayub, Nicolás Daniel (Springer, 2015-10)
      The vast majority of Pseudomonas species are unable to fix atmospheric nitrogen. Although several studies have demonstrated that some strains belonging to the genus Pseudomonas sensu stricto do have the ability to fix ...
    • Genetic diversity in a world germplasm collection of tall fescue 

      Cuyeu, Alba Romina; Rosso, Beatriz Susana; Pagano, Elba Maria; Soto, Gabriela; Fox, Ana Romina; Ayub, Nicolás Daniel (2013)
      Festuca arundinacea Schreb., commonly known as tall fescue, is a major forage crop in temperate regions. Recently, a molecular analysis of different accessions of a world germplasm collection of tall fescue has demonstrated ...
    • Major cereal crops benefit from biological nitrogen fixation when inoculated with the nitrogen-fixing bacterium Pseudomonas protegens Pf-5 X940 

      Fox, Ana Romina; Soto, Gabriela Cinthia; Valverde, Claudio Fabián; Russo, Daniela Marta; Lagares, Antonio; Zorreguieta, Ángeles; Pascuan, Cecilia Gabriela; Frare, Romina Alejandra; Mercado Blanco, Jesús; Dixon, Ray; Ayub, Nicolás Daniel; Alleva, Karina Edith (2016)
      A main goal of biological nitrogen fixation research has been to expand the nitrogen-fixing ability to major cereal crops. In this work, we demonstrate the use of the efficient nitrogen-fixing rhizobacterium Pseudomonas ...
    • Pseudomonas fluorescens Pf-5 genome-wide mutant screen for resistance to the antimicrobial peptide alfalfa snakin-1 

      Ayub, Nicolás Daniel; Fox, Ana Romina; Garcia, Araceli Nora; Mozzicafreddo, Matteo; Cuccioloni, Massimiliano; Angeletti, Mauro; Pagano, Elba Maria; Soto, Gabriela Cynthia (Oxford University Press, 2015-01)
      Snakin-1, a peptide produced by higher plants, has broad-spectrum antibiotic activity, inhibiting organisms ranging from Bacteria to Eukaryotes. However, the mode of action against target organisms is poorly understood. ...
