    • CRISPR/Cas9-mediated knockout of a polyester synthase-like gene delays flowering time in alfalfa 

      Galindo Sotomonte, Luisa Fernanda; Jozefkowicz, Cintia; Gomez, Maria Cristina; Stritzler, Margarita; Frare, Romina Alejandra; Bottero, Ana Emilia; Tajima, Hiromi; Blumwald, Eduardo; Ayub, Nicolás Daniel; Soto, Gabriela Cynthia (Springer, 2023-02)
      Alfalfa (Medicago sativa), commonly known as the “Queen of Forages”, is the main source of plant protein for meat and milk production systems worldwide. Since alfalfa is a perennial vegetative-harvest forage, delaying ...

    • CRISPR/Cas9‑mediated knockout of SPL13 radically increases lettuce yield 

      Beracochea, Valeria Cecilia; Stritzler, Margarita; Radonic, Laura Mabel; Bottero, Ana Emilia; Jozefkowicz, Cintia; Darqui, Flavia Soledad; Ayub, Nicolás Daniel; Lopez Bilbao, Marisa Gisela; Soto, Gabriela Cynthia (Springer, 2022-12)
      Cultivated lettuce (Lactuca sativa L.) is a diploid (2n = 2x = 18), autogamous species. This popular leafy vegetable is considered one of the first crops (Guo et al. 2022). Currently, lettuce is the third most consumed ...

    • Efficient CRISPR/Cas9 genome editing in alfalfa using a public germplasm 

      Bottero, Ana Emilia; Massa, Gabriela Alejandra; Gonzalez, Matías Nicolás; Stritzler, Margarita; Tajima, Hiromi; Gomez, Maria Cristina; Frare, Romina Alejandra; Feingold, Sergio Enrique; Blumwald, Eduardo; Ayub, Nicolás Daniel; Soto, Gabriela Cynthia (Frontiers Media, 2021-07)
      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 ...

    • 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 ...

    • Microevolution rather than large genome divergence determines the effectiveness of legume–rhizobia symbiotic interaction under field conditions 

      Jozefkowicz, Cintia; Brambilla, Silvina Maricel; Frare, Romina Alejandra; Stritzler, Margarita; Puente, Mariana Laura; Piccinetti, Carlos Fabian; Soto, Gabriela Cinthia; Ayub, Nicolás Daniel (2017-08)
      Despite the vast screening for natural nitrogenfixing isolates by public and private consortia, no significant progresses in the production of improved nitrogenfixing inoculants for alfalfa production have been made in the ...

    • Rapid and cloning‑free screening of edited alfalfa via next‑generation sequencing 

      Stritzler, Margarita; Pascuan, Cecilia Gabriela; Bottero, Ana Emilia; Gomez, Maria Cristina; Frare, Romina Alejandra; Puebla, Andrea Fabiana; Tajima, Hiromi; Ayub, Nicolás Daniel; Blumwald, Eduardo; Soto, Gabriela Cynthia (Springer, 2022-07)
      The identification of full knockout plants is frequently the rate-limiting step of the research and commercial projects searching the complete loss of the function of target genes via the CRISPR/Cas9 system. This problem ...

    • Retrotransposon and CRISPR/Cas9‑mediated knockout of NOD26 impairs the legume‑rhizobia symbiosis 

      Frare, Romina Alejandra; Stritzler, Margarita; Gomez, Maria Cristina; Tajima, Hiromi; Pascuan, Cecilia Gabriela; López Fernández, María Paula; Bottero, Ana Emilia; Nikel, Pablo I.; Alleva, Karina Edith; Ayub, Nicolás Daniel; Blumwald, Eduardo; Soto, Gabriela Cynthia (Springer, 2022-07)
      The multifunctional channel NOD26, identified and extensively studied (both biochemically and biophysically) in soybean, is a major protein component of the symbiosome membrane. The water and ammonia transport activities ...

    • Stable symbiotic nitrogen fixation under water-deficit field conditions by a stress-tolerant alfalfa microsymbiont and its complete genome sequence : Short communication 

      Jozefkowicz, Cintia; Brambilla, Silvina Maricel; Frare, Romina Alejandra; Stritzler, Margarita; Piccinetti, Carlos Fabian; Puente, Mariana Laura; Berini, Carolina Andrea; Reyes Perez, Pedro Jose; Soto, Gabriela Cinthia; Ayub, Nicolás Daniel (2017-12)
      We here characterized the stress-tolerant alfalfa microsymbiont Sinorhizobium meliloti B401. B401-treated plants showed high nitrogen fixation rates under humid and semiarid environments. The production of glycine betaine ...

    • Synthetic multi-antibiotic resistant plasmids in plant-associated bacteria from agricultural soils 

      Brambilla, Silvina Maricel; Frare, Romina Alejandra; Stritzler, Margarita; Soto, Gabriela Cynthia; Berini, Carolina Andrea; Jozefkowicz, Cintia; Ayub, Nicolás Daniel (Elsevier, 2020-09)
      Objectives: Unlike higher organisms such as domestic animals and cultivated plants, which display a robust reproductive isolation and limited dispersal ability, microbes exhibit an extremely promiscuous gene flow and can ...

    • Whole-Genome Resequencing of Spontaneous Oxidative Stress-Resistant Mutants Reveals an Antioxidant System of Bradyrhizobium japonicum Involved in Soybean Colonization 

      Liebrenz, Karen Ivana; Gomez, Maria Cristina; Brambilla, Silvina Maricel; Frare, Romina Alejandra; Stritzler, Margarita; Maguire, Vanina; Ruiz, Oscar; Soldini, Diego Omar; Pascuan, Cecilia Gabriela; Soto, Gabriela Cynthia; Ayub, Nicolás Daniel (Springer, 2021-11)
      Soybean is the most inoculant-consuming crop in the world, carrying strains belonging to the extremely related species Bradyrhizobium japonicum and Bradyrhizobium diazoefficiens. Currently, it is well known that B. japonicum ...
