A synthesis of functional contributions of rhizobacteria to growth promotion in diverse crops
Brambilla, Silvina Maricel; Stritzler, Margarita; Soto, Gabriela Cynthia; Ayub, Nicolás Daniel (Elsevier, 2022-12)The endophytic microbes are known to live asymptomatically inside their host and play crucial roles in the growth, development, fitness, and diversification of plants. The plant-endophyte association ranges from mutualism ... -
Absence of the nitrous oxide reductase gene cluster in commercial alfalfa inoculants is probably due to the extensive loss of genes during rhizobial domestication
Brambilla, Silvina Maricel; Frare, Romina Alejandra; Soto, Gabriela Cinthia; Jozefkowicz, Cintia; Ayub, Nicolás Daniel (Springer, 2018-08)As other legume crops, alfalfa cultivation increases the emission of the greenhouse gas nitrous oxide (N2O). Since legumesymbiotic nitrogen-fixing bacteria play a crucial role in this emission, it is important to understand ... -
Characterization of genetic diversity in accessions of prunus salicina lindl : keeping fruit flesh color ideotype while adapting to water stressed environments
Acuña, Cintia Vanesa; Rivas, Juan Gabriel; Brambilla, Silvina Maricel; Cerrillo, Teresa; Frusso, Enrique; Garcia, Martin Nahuel; Villalba, Pamela Victoria; Aguirre, Natalia Cristina; Sabio Y Garcia, Julia Veronica; Martinez, Maria Carolina; Hopp, Horacio Esteban; Marcucci Poltri, Susana Noemi (MDPI, 2019-08)The genetic diversity of 14 Japanese plum (Prunus salicina Lindl) landraces adapted to an ecosystem of alternating flooding and dry conditions was characterized using neutral simple sequence repeat (SSR) markers. Twelve ... -
Exploring the cooperation between nitrogen-fixing and non-fixing alfalfa rhizobia
Brambilla, Silvina Maricel; Liebrenz, Karen Ivana; Odorizzi, Ariel; Arolfo, Valeria; Maguire, Vanina Giselle; Moreno, Maria Valeria; Ruiz, Oscar Adolfo; Stritzler, Margarita; Serantes, Maria Laura; Soto, Gabriela Cynthia; Ayub, Nicolás Daniel (Springer, 2024-07-05)Alfalfa plays a crucial role in agriculture due to its nitrogen-fixing partnership with rhizobia, resulting in nutritious forage. While the potential parasitic action of inefficient rhizobia has been extensively studied, ... -
Genome editing of soybean inoculant using CRISPR/Cas9 system: enhancing agricultural sustainability
Serantes, Maria Laura; Stritzler, Margarita; Brambilla, Silvina Maricel; Soto, Gabriela Cynthia; Ayub, Nicolás Daniel (Springer, 2024-04)In modern agriculture, inoculants, consisting of various bacteria and fungi, are essential for promoting crop growth and sustainability while reducing reliance on agrochemicals. Despite their benefits, there have been no ... -
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 ... -
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 ... -
Oligopeptide uptake improves oxidative stress resistance and nodulation competitiveness in soybean rhizobia
Brambilla, Silvina Maricel; Liebrenz, Karen Ivana; Frare, Romina Alejandra; Gomez, Maria Cristina; Stritzler, Margarita; Soto, Gabriela Cynthia; Ayub, Nicolás Daniel (Elsevier, 2023-12)We here explored the mechanisms associated with oxidative stress resistance and root colonization by soybean rhizobia. Genomic and physiological analyses supported the fact that the mutation of a highly conserved valine ... -
Spontaneous Mutations in the Nitrate Reductase Gene napC Drive the Emergence of Eco-friendly Low-N2O-Emitting Alfalfa Rhizobia in Regions with Different Climates
Brambilla, Silvina Maricel; Soto, Gabriela; Odorizzi, Ariel; Arolfo, Valeria; McCormick, Wayne; Primo, Emiliano; Giordano, Walter; Jozefkowicz, Cintia; Ayub, Nicolás Daniel (Springer, 2020)We have recently shown that commercial alfalfa inoculants (e.g., Sinorhizobium meliloti B399), which are closely related to the denitrifier model strain Sinorhizobium meliloti 1021, have conserved nitrate, nitrite, and ... -
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 ... -
