(Submitter supplied) To explore the effect of light perception on Pseudomonas syringae pv. tomato DC3000 at a global level, we carried out microarray hybridization experiments. We hybridize custom-designed microarrays (Agilent Technologies) with probes isolated from PsPto after a 10 min treatment with either 20 μE/m2s blue light, 20 μE/m2s red light, 70 μE/m2s white light, or cells kept in the darkness.

(Submitter supplied) The plant pathogen Pseudomonas syringae pv. syringae B728a grows and survives on leaf surfaces and in the leaf apoplast of its host, bean. Global transcriptome profiling was used to understand the contribution of distinct regulators to B728a fitness and pathogenicity. We performed a transcriptome analysis of B728a and nine regulator mutants recovered from the surface and interior of leaves and exposed to various environmental stresses in culture. more...

(Submitter supplied) As mechanical stimuli, sound vibrations are known to influence various molecular and physiological processes that can ultimately improve crop performance and yield. Microarray analyses were carried out to investigate the global gene expression changes in MicroTom plants subjected to 1000 Hz sound vibration prior to infection with Pst DC300 to test the effectiveness of sound as a priming agent. Data revealed that 1000 Hz pretreatment is effective in eliciting a transcriptional reprogramming in tomato plants grown under normal conditions, but particularly after Pst DC3000 infection. more...

(Submitter supplied) This RNA-seq analysis examined the global effect of (p)ppGpp in P. syringae under the T3SS-inducing condition. The (p)ppGpp mutant showed differential expression of more than 30% genes in the genome, which include significant down-regulation of T3SS genes and those required for cell growth and viability.

(Submitter supplied) In order to obtain a global view about the strategies used by phytopathogenic bacteria, in response to physiologically relevant temperature changes. We used the DNA microarray technology to compare gene expression profile in the model bacterial pathogen P. syringae pv. phaseolicola NPS3121 grown at 18 ºC and 28ºC.

(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...
