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 ... -
Plant growth-promoting bacterium Pseudomonas fluorescens FR1 secrets a novel type of extracellular polyhydroxybutyrate polymerase involved in abiotic stress response in plants
Stritzler, Margarita; Diez Tissera, Ana; Soto, Gabriela; Ayub, Nicolás Daniel (Springer, 2018)Objectives Identification of novel microbial factors contributing to plant protection against abiotic stress. Results The genome of plant growth-promoting bacterium Pseudomonas fluorescens FR1 contains a short mobile ... -
Plant growth-promoting genes can switch to be virulence factors via horizontal gene transfer
Stritzler, Margarita; Soto, Gabriela; Ayub, Nicolás Daniel (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 ... -
Understanding the intracellular-to-extracellular localization switch of polyhydroxybutyrate polymerase in pseudomonas backgrounds as a microevolutionary process
Stritzler, Margarita; Berini, Carolina Andrea; Jozefkowicz, Cintia; Soto, Gabriela Cinthia; Ayub, Nicolás Daniel (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 ...
