Análisis y caracterización de poblaciones bacterianas solubilizadoras de P en un ensayo de larga duración con diferentes secuencias de cultivo
(Asociación Argentina de Ecología, 2023-02-12)Se conoce bien que diferentes sistemas de uso y manejos de suelos afectan la abundancia, la actividad y la composición de la comunidad microbiana del suelo. En este trabajo se estudió el comportamiento de las poblaciones ... -
Bioinoculación de Chloris gayana cv. Finecut con Pseudomonas tolaasii IEXb y Bacillus atrophaeus CN4: estudio preliminar en la Llanura Deprimida Salina de Tucumán, Argentina = Bioinoculation of Chloris gayana cv. Finecut with Pseudomonas tolaasii IEXb and Bacillus atrophaeus CN4: a prelimilary study in Saline Depressed Plane of Tucumán, Argentina
(Facultad de Agronomía y Zootecnia, Universidad Nacional de Tucumán, 2017)El uso de bioinoculantes presenta ventajas en la germinación y crecimiento vegetal, convirtiéndolos en una alternativa para favorecer la implantación e incrementar la producción de pasturas megatérmicas en el marco de la ... -
Bioinoculación de pasturas megatérmicas con Pseudomonas Tolaasii IEXb: estudio preliminar en la llanura deprimida salina de Tucumán
(Asociación Argentina de Microbiología, 2019-11-14)En los últimos años, la ganadería nacional ha sido desplazada de la zona pampeana hacia otras regiones como el Noroeste argentino (NOA) debido, principalmente, al proceso de intensificación y crecimiento de la superficie ... -
Characterization of Cellulolytic Activities of Environmental Bacterial Consortia from an Argentinian Native Forest
(Springer, 2013-08)Cellulolytic activities of three bacterial consortia derived from a forest soil sample from Chaco region, Argentina, were characterized. The phylogenetic analysis of consortia revealed two main highly supported groups ... -
Criterios de selección fenotípica en el mejoramiento vegetal: mirando debajo de la alfombra
(INTA, 2022-11-03)¿En qué punto nos encontramos? Creciente demanda mundial de alimentos. Necesidad de aumentar la productividad de los cultivos en forma sustentable. Contraste con los objetivos de la revolución verde del siglo XX: aumento ... -
Engineering Pseudomonas protegens Pf-5 for nitrogen fixation and its application to improve plant growth under nitrogen-deficient conditions
(2013-05-13)Nitrogen is the second most critical factor for crop production after water. In this study, the beneficial rhizobacterium Pseudomonas protegens Pf-5 was genetically modified to fix nitrogen using the genes encoding the ... -
Exploring the ancestral mechanisms of regulation of horizontally acquired nitrogenases
(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 ... -
Major cereal crops benefit from biological nitrogen fixation when inoculated with the nitrogen-fixing bacterium Pseudomonas protegens Pf-5 X940
(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 ... -
Plant growth-promoting genes can switch to be virulence factors via horizontal gene transfer
(Springer, 2018-10)There are increasing evidences that horizontal gene transfer (HGT) is a critical mechanism of bacterial evolution, while its complete impact remains unclear. A main constraint of HGT effects on microbial evolution seems ... -
Pseudomonas fluorescens Pf-5 genome-wide mutant screen for resistance to the antimicrobial peptide alfalfa snakin-1
(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. ... -
Understanding the intracellular-to-extracellular localization switch of polyhydroxybutyrate polymerase in pseudomonas backgrounds as a microevolutionary process
(Elsevier, 2018-11)After gene duplication, paralogous genes evolve independently, and consequently, the new proteins encoded by these duplicated genes are exposed to changes in their subcellular location. Although there are increasing evidence ...
