Project description:Pectobacterium are Gram-negative rods of the family Pectobacteriaceae. They are the causative agent of soft rot diseases of crops and ornamental plants. However, their virulence mechanisms are not yet fully elucidated. Membrane vesicles (MVs) are universally released by bacteria and are be-lieved to play an important role in pathogenicity, and survival of bacteria in the environment. Our study investigates the role of MVs in the virulence of Pectobacterium. The results indicate that the morphology and yields of MVs depend on medium composition. In polygalacturonic acid (PGA) supplemented media, Pectobacterium produce MVs of a larger size (100-300 nm) apart of vesicles below 100 nm. Proteomic analyses revealed the presence of pectate degrading enzymes in MVs. The pectate plate test and enzymatic assay proved that those enzymes are active and able to de-grade pectates. What is more, pathogenicity test indicated that MVs derived from Pectobacterium were able to induce maceration of Zantedeschia sp. leaves. We also show that MVs of β-lactamase producing strains were able to suppress ampicillin activity and permit the growth of susceptible bacteria. Those findings indicate that MVs of Pectobacterium play an important role in host-pathogen interactions and niche competition with other bacteria. Our research also sheds some light on the mechanism of MVs production. We demonstrate that Pectobacterium strains, which overexpress the green fluorescence protein (GFP), produce more MVs than wild type strains. Moreover, proteomic analysis revealed that GFP was present in MVs. Therefore, we demonstrate that protein sequestration into MVs is not limited strictly to periplasmic proteins and is a common occurrence. Our research highlights the importance of MVs production as a mechanism of cargo delivery in Pectobacterium and an alternative secretion system.

Project description:To investigate whether C. parvum treatment of DCs regulates other inflammatory genes, mouse BMDCs (CD11c and CD11b positive) were treated with C. parvum for 24 hr. Control groups included untreated BMDCs and DCs treated with E. cuniculi. We noticed that a significant upregulation of the expression of interferon-related genes, which may correlation the critical role of interferon in host defense against C. parvum infection. DCs were treated with C. parvum for 24 hr. Control groups included untreated BMDCs and DCs treated with E. cuniculi. Group comparison was performed using the data of 3 replicate arrays from each time point.

Project description:Whole genome analysis of gene expression by Pectobacterium atrosepticum strain SCRI1043 wildtype and its relA, expI and rpoS deletion mutants when grown to exponential and stationary phase in PMB media. The data is further described in Bowden et al (2013) Virulence in Pectobacterium atrosepticum is regulated by a coincidence circuit involving quorum sensing and the stress alarmone, (p)ppGpp. Molecular Microbiology.
