(Submitter supplied) Pseudomonas syringae pv. syringae 9644 (Pss9644) is a causal agent of bacterial cherry canker causing necrotic symptoms on leaves, fruits, gummosis and canker in woody tissues of sweet cherry (Prunus avium). To understand which virulent factor genes were expressed in vitro, Pss9644 was grown in rich media (King's B Broth) and minimum media (hrp-inducing minimum media). The latter mimics the in planta environment.

(Submitter supplied) The ecological significance of light perception in non-phototrophic bacteria remains largely elusive. In terrestrial environments, diurnal oscillations in light are often temporally coupled to other environmental changes, including increased temperature and evaporation. Here we report that light functions as an anticipatory cue that triggers protective adaptations to tolerate a future rapid loss of environmental water in leaf-associated Pseudomonas syringae pv. more...

(Submitter supplied) We sought to compare and contrast plant host and bacterial transcriptional changes during compatible infections that cause disease (albeit within different symptoms). We investigated the infection by the two Pseudomonas syringae sensu lato strains P. syringae pv. syringae B728a (Psy) and P. amygdali pv. tabaci 11528 (Pta) of Nicotiana benthamiana at an early time point post inoculation to understand how a plant host responds to two related bacteria with different infection strategies. more...

(Submitter supplied) Many bacteria can transition from a planktonic lifestyle to life attached to a surface. Changes in gene expression have been documented in bacteria in mature biofilms, but few studies have looked at gene expression during the initial stages of surface attachment. To investigate this, we performed RNA-Seq using the model organism Pseudomonas syringae B728a which has been found in rivers and lakes but is known for living on the leaf surface. more...

(Submitter supplied) Although the ubiquitous bacterial secondary messenger cyclic diguanylate (c-di-GMP) plays important roles in various cellular functions including the formation of biofilm in a wide range of bacteria, its function in model plant pathogen Pseudomonas syringae is largely elusive. In order to test this in P. syringae, we overexpressed a diguanylate cyclase (YedQ) and a phosphodiesterase (YhjH) that are originally from Escherichia coli, resulting in high and low c-di-GMP levels in P. more...
