      Because its ability to acquire large amounts of nitrogen by symbiosis, tetraploid alfalfa is the main source of vegetable proteins in meat and milk production systems in temperate regions. Alfalfa cultivation also adds ...

    • Expanding the benefits of Tnt1 for the identification of dominant mutations in polyploid crops: A single allelic mutation in the MsNAC39 gene produces multifoliated alfalfa 

      Jozefkowicz, Cintia; Gomez, Maria Cristina; Odorizzi, Ariel; Iantcheva, Anelia; Ratet, Pascal; Ayub, Nicolás Daniel; Soto, Gabriela Cynthia (Frontiers Media, 2022-04)
      Most major crops are polyploid species and the production of genetically engineered cultivars normally requires the introgression of transgenic or gene-edited traits into elite germplasm. Thus, a main goal of plant research ...

    • Generation of a multi‑herbicide‑tolerant alfalfa by using base editing 

      Bottero, Ana Emilia; Gomez, Maria Cristina; Stritzler, Margarita; Tajima, Hiromi; Frare, Romina Alejandra; Pascuan, Cecilia Gabriela; Blumwald, Eduardo; Ayub, Nicolás Daniel; Soto, Gabriela Cynthia (Springer, 2022-02)
      We present the first report on base editing in alfalfa. Specifically, we showed edited alfalfa with tolerance to both sulfonylurea- and imidazolinone-type herbicides. Alfalfa (Medicago sativa) is one of the most important ...

    • High-quality forage production under salinity by using a salt-tolerant AtNXH1-expressing transgenic alfalfa combined with a natural stress-resistant nitrogen-fixing bacterium 

      Stritzler, Margarita; Pagano, Elba Maria; Berini, Carolina Andrea; Gomez, Maria Cristina; Ayub, Nicolás Daniel; Soto, Gabriela Cinthia (Elsevier, 2018-06)
      Alfalfa, usually known as the “Queen of Forages”, is the main source of vegetable protein to meat and milk production systems worldwide. This legume is extremely rich in proteins due to its highly efficient symbiotic ...

    • Multiple ways to evade the bacteriostatic action of glyphosate in rhizobia include the mutation of the conserved serine 90 of the nitrogenase subunit NifH to alanine 

      Liebrenz, Karen Ivana; Frare, Romina Alejandra; Gomez, Maria Cristina; Pascuan, Cecilia Gabriela; Brambilla, Silvina Maricel; Soldini, Diego Omar; Maguire, Vanina; Carrio, Alejandro Javier; Ruiz, Oscar; McCormick, Wayne; Soto, Gabriela Cynthia; Ayub, Nicolás Daniel (Elsevier, 2022-07)
      The genome resequencing of spontaneous glyphosate-resistant mutants derived from the soybean inoculant E109 allowed identifying genes most likely associated with the uptake (gltL and cya) and metabolism (zigA and betA) of ...
