Genetic diversity in a world germplasm collection of tall fescue
Cuyeu, Alba Romina; Rosso, Beatriz Susana; Pagano, Elba Maria; Soto, Gabriela; Fox, Ana Romina; Ayub, Nicolás Daniel (2013)Festuca arundinacea Schreb., commonly known as tall fescue, is a major forage crop in temperate regions. Recently, a molecular analysis of different accessions of a world germplasm collection of tall fescue has demonstrated ... -
LOV‐domain photoreceptor, encoded in a genomic island, attenuates the virulence of Pseudomonas syringae in light‐exposed Arabidopsis leaves
Moriconi, Victoria; Sellaro, Romina Vanesa; Ayub, Nicolás Daniel; Soto, Gabriela; Rugnone, Matias Leandro; Shah, Rashmi; Pathak, Gopal P.; Gärtner, Wolfgang; Casal, Jorge José (Wiley, 2013-10)In Arabidopsis thaliana, light signals modulate the defences against bacteria. Here we show that light perceived by the LOV domain‐regulated two‐component system (Pst–Lov) of Pseudomonas syringae pv. tomato DC3000 (Pst ... -
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 ...
