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 ... -
Phenotypic heterogeneity inside the leaf: Pseudomonas syringae within its host
López-Pagán, Nieves; Rufián Plaza, José Sebastián; López-Márquez, Diego; Ruiz-Albert, Francisco Javier; Beuzón-López, Carmen del Rosario (2017-09-06)
Backgrounds Heterogeneity or phenotypic variation has been known to take place in microbial clonal populations for decades. Under certain regulatory circuits, heterogeneity in gene expression can be enhanced leading to a ... -
Phenotypically heterogeneous loci in the plant pathogen Pseudomonas syringae.
