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...

The LysR‐type transcription factor LsrB regulates beta‐lactam resistance in Agrobacterium tumefaciens

(Submitter supplied) We investigated the role of the LysR-type transcriptional regulator LsrB (Atu2186) from Agrobacterium tumefaciens C58 (alias A. fabrum C58), which regulates the expression of small-regulatory-RNA (sRNA) and several protein-coding genes, such as ampD (atu2113). In our current study we invesigated the role of LsrB in beta-lactam resistance. For this purpose, we constructed a vtlR/lsrB deletion mutant. 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...

Decreased Peptidoglycan Synthesis Induces the RSI Invasion Switch in Agrobacterium tumefaciens

(Submitter supplied) We report that depletion of PBP1a in Agrobacterium tumefaciens induces transcriptional changes remarkably similar to the RSI invasion switch. Using RNA-seq with NextSeq 500 sequencing, we identified genes that are differentially expressed during depletion of PBP1a after 6 hours and after 16 hours. Depletion of PBP1a after 6 hours results in upregulation in genes associated with Type VI Secretion and succinoglycan production and downregulation of genes associated with flagellar motility and chemotaxis. more...

The LysR-type transcriptional regulator VtlR/LsrB controls expression of multiple small RNA and small protein genes in Agrobacterium tumefaciens

(Submitter supplied) We investigated the role of the LysR-type transcriptional regulator VtlR/LsrB (Atu2186) from Agrobacterium tumefaciens C58 (alias A. fabrum C58), which regulates the expression of small-regulatory-RNA (sRNA) genes such as AbcR1 and the expression of genes encoding small proteins with a domain of unknown function DUF1127. For this purpose, we constructed a vtlR/lsrB deletion mutant. Total RNA was isolated from this mutant as well as from an AbcR1 deletion mutant (Wilms et al., 2011) at optical densities (OD) of 0.5 or 0.5 and 1.5, respectively. more...

Arginine-rich small proteins with a domain of unknown function DUF1127 play a role in phosphate and carbon metabolism of Agrobacterium tumefaciens

(Submitter supplied) The genome of Agrobacterium tumefaciens C58 harbors three genes encoding small proteins (<50 aa) with a domain of unknown function DUF1127 (ATU_RS08170, ATU_RS08175, ATU_RS21905). To investigate their function we created a triple-deletion mutant lacking those genes. Total RNA was isolated from A. tumefaciens wild type and from the triple mutant (∆∆∆) at optical densities (OD) of 0.5 and 1.5, and after 24 h of growth (30 °C in YEB medium at 180 rpm) and sequenced on an Illumina platform. more...

The Epigenomic Landscape of Prokaryotes

(Submitter supplied) DNA methylation is an important regulator of genome function in the eukaryotes, but it is currently unclear if the same is true in prokaryotes. While regulatory functions have been demonstrated for a small number of bacteria, there have been no large-scale studies of prokaryotic methylomes and the full repertoire of targets and biological functions of DNA methylation remains unclear. Here we applied single-molecule, real-time sequencing to directly study the methylomes of 232 phylogenetically diverse prokaryotes. more...

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...

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...
