Contribution of Phenotypic Heterogeneity to plant colonization by Pseudomonas syringae
López-Pagán, Nieves; Sánchez-Romero, María Antonia; Rufián Plaza, José Sebastián; Govantes, Fernando; Ruiz-Albert, Francisco Javier
; Beuzón-López, Carmen del Rosario[et al.] (2022)
In bacterial clonal populations, cell to cell differences can be originated by the response to different stimuli present in the environment. However, the sources of variation may not always be directly correlated with ... -
Expresión heterogénea y colonización de la planta en Pseudomonas syringae
López-Pagán, Nieves; Sánchez-Romero, María Antonia; Rufián Plaza, José Sebastián; Aussel, Laurent; Casadesús, Josep; Ruiz-Albert, Francisco Javier; Beuzón-López, Carmen del Rosario[et al.] (2019-01-31)
La heterogeneidad fenotípica se ha descrito en poblaciones clonales durante décadas. La heterogeneidad o ruido en la expresión génica puede dar lugar a un patrón de expresión bimodal. Este proceso donde la población se ... -
Expression of flagellar and type III secretion systems is under stochastic and deterministic regulation in Pseudomonas syringae.
López-Pagán, Nieves; Rufián Plaza, José Sebastián; Sánchez-Romero, María Antonia; Aussel, Laurent; Casadesús, Josep; Govantes, Fernando; Ruiz-Albert, Francisco Javier; Beuzón-López, Carmen del Rosario[et al.] (2023)
We previously described bistability and phenotypic heterogeneity of the type III secretion system (T3SS) of Pseudomonas syringae (Rufián et al., 2016). First example of such phenomenon in a plant pathogen. Here, we describe ... -
Metilasas y metilación en la regulación génica de Pseudomonas syringae
Mancera-Miranda, Laura; López-Pagán, Nieves; Gutiérrez del Pozo, Gabriel; Spröer, Cathrin; Bunk, Boyke; Sánchez-Romero, María Antonia; Ruiz-Albert, Francisco Javier; Beuzón-López, Carmen del Rosario[et al.] (2022)
La metilación del ADN llevada a cabo por metilasas no asociadas a enzimas de restricción, conocidas como metilasas huérfanas, es un mecanismo epigenético ampliamente extendido en bacterias y archeas. La especificidad de ... -
Phenotypic heterogeneity during plant colonization
López-Pagán, Nieves; Sánchez-Romero, María Antonia; Rufián Plaza, José Sebastián; Aussel, Laurent; Govantes, Fernando; Schikora, Adam; Ruiz-Albert, Francisco Javier; Beuzón-López, Carmen del Rosario[et al.] (2019-07-29)
Isogenic bacterial populations can display phenotypic differences. Cell-to-cell phenotypic differences can be a consequence of noisy gene expression, or a programmed event under genetic or epigenetic control. Bistability ... -
Phenotypic heterogeneity in Pseudomonas syringae
López-Pagán, Nieves; Sánchez-Romero, María Antonia; Rufián Plaza, José Sebastián; Aussel, Laurent; Govantes, Fernando; Ruiz-Albert, Francisco Javier[et al.] (2019-07-29)
The notion of isogenic bacterial populations displaying phenotypic differences is widely accepted today. A particular case of phenotypic heterogeneity is bistability. Bistability occurs when bacterial population splits ... -
Phenotypically heterogeneous loci in the plant pathogen Pseudomonas syringae.
Mancera-Miranda, Laura; López-Pagán, Nieves; Rufián Plaza, José Sebastián; Sánchez-Romero, María Antonia; Gutierrez-Pozo, Gabriel; Spröer, Cathrin; Bunk, Boyke; Ruiz-Albert, Francisco Javier; Beuzón-López, Carmen del Rosario[et al.] (2023)
Phenotypic heterogeneity usually refers to the co-existance of different phenotypes within a population. Phenotypic differences may arise through genetic variation (genomic rearrangements or mutations) or through the ... -
Pseudomonas syringae flagella displays phenotypic heterogeneity
López-Pagán, Nieves; Sánchez-Romero, María Antonia; Rufián Plaza, José Sebastián; Govantes, Fernando; Ruiz-Albert, Francisco Javier (2022)
Pseudomonas syringae is a plant-pathogenic bacteria that infects a lot of plant with economic relevance. It is ubiquitous in nature colonizing a wide range of niches including water, soil and plant phyllosphere and ...
