RNA-seq gene expression profiling comparing WT and DccrM Ptac-ccrM Agrobacterium tumefaciens C58 cells cultivated in ATGN+/-IPTG.

(Submitter supplied) The cell cycle-regulated DNA methyltransferase CcrM is conserved in most Alphaproteobacteria, but its role in bacteria with complex or multicentric genomes remains unexplored. Here, we compare the methylome, the transcriptome and the phenotypes of wild-type and CcrM-depleted Agrobacterium tumefaciens cells with a dicentric genome with two essential replication origins. We find that DNA methylation has a pleiotropic impact on motility, biofilm formation and viability. more...

Centromere interactions promote the maintenance of the multipartite genome in Agrobacterium tumefaciens

(Submitter supplied) Many pathogens and symbionts contain multipartite genomes, but how they are stably maintained is poorly understood. The plant pathogen, Agrobacterium tumefaciens, contains four replicons. Recent work indicates that their replication origins cluster at cell poles in a manner that depends on their ParB-family centromeric proteins. Here, we provide evidence that centromeric clustering is mediated by interactions between these centromeric proteins. more...

Conformation and dynamic interactions of the multipartite genome in Agrobacterium tumefaciens

(Submitter supplied) Bacterial species from diverse phyla contain multiple replicons, yet how these multipartite genomes are organized and segregated during the cell cycle remains poorly understood. Agrobacterium tumefaciens has a 2.8 Mb circular chromosome (Ch1), a 2.1 Mb linear chromosome (Ch2), and two large plasmids (pAt and pTi). We used this alpha proteobacterium as a model to investigate the global organization and temporal segregation of a multipartite genome. more...

Trancriptome analysis of Agrobacterium tumefaciens C58 cells in the presence of abundant opines

Comparison of expression profiles for Agrobacterium tumefaciens wild-type strain C58 and isogenic pdhS2 (Atu1888) deletion strain

(Submitter supplied) A conserved regulatory pathway directs developmental transitions and asymmetries in Agrobacterium tumefaciens. Core components of this coordination of division and development (CDD) pathway include two integrated phosphorelays. One of these phosphorelays includes at least four histidine sensor kinase homologues, DivJ, PleC, PdhS1, and PdhS2, and at least two response regulators, DivK and PleD. Previously we demonstrated that PdhS2 reciprocally regulates biofilm formation and swimming motility. more...

Comparison of expression profiles for Agrobacterium tumefaciens wild-type strain C58 grown with or without manganese

(Submitter supplied) The plant pathogen Agrobacterium tumefaciens attaches to and forms biofilms on both biotic and abiotic surfaces. The transition between free-living, planktonic A. tumefaciens and multicellular biofilms is regulated by several well-defined environmental and nutritional inputs, including pH, oxygen tension, and phosphate concentration. In many bacterial species limiting iron levels inhibit attachment and biofilm formation. more...

Identification of Hfq bound RNA by co-immunoprecipitation and RNA-sequencing

(Submitter supplied) Co-immunoprecipitation with endogenous Hfq3xFlag in exponential, stationary, non-induced and virulence induced conditions, followed by RNA-sequencing, revealed 1697 mRNAs and 208 ncRNAs associated with Hfq. We identified 56 new ncRNAs and validated 3 Hfq-dependent trans sRNAs on by Northern blot analysis. Interestingly, 55% of the ncRNAs were encoded antisense to a protein coding sequence. Abundance of 4 asRNAs and their corresponding target mRNAs was altered upon hfq, indicating a substantial influence of Hfq on asRNA-target interactions.

Comparison of Expression Profiles for Agrobacterium tumefaciens visR mutant to wild-type strain.

(Submitter supplied) Many bacteria colonize surfaces and transition to a sessile mode of growth. The plant pathogen Agrobacterium tumefaciens produces a unipolar polysaccharide (UPP) adhesin at single cell poles that contact surfaces. Here we report that elevated levels of the intracellular signal cyclic diguanosine monophosphate (c-di-GMP) lead to surface-contact-independent UPP production and a red colony phenotype due to production of UPP and the exopolysaccharide cellulose, when A. more...

Comparison of Expression Profiles for Agrobacterium tumefaciens exoRexoA double mutant to exoA mutant

(Submitter supplied) Agrobacterium tumefaciens is a facultative plant pathogen and the causative agent of crown gall disease. The initial stage of infection involves attachment to plant tissues and, subsequently, biofilms may form at these sites. This study focuses on the periplasmic ExoR regulator, which was identified based on the severe biofilm deficiency of A. tumefaciens exoR mutants. Genome-wide expression analysis was performed to elucidate the complete ExoR regulon. more...
