A species of gram-negative, aerobic bacteria that consist of slender vibroid cells.
Caulobacter
A genus of gram-negative, aerobic, rod- or vibroid-shaped or fusiform bacteria that commonly produce a stalk. They are found in fresh water and soil and divide by binary transverse fission.
Flagella
A whiplike motility appendage present on the surface cells. Prokaryote flagella are composed of a protein called FLAGELLIN. Bacteria can have a single flagellum, a tuft at one pole, or multiple flagella covering the entire surface. In eukaryotes, flagella are threadlike protoplasmic extensions used to propel flagellates and sperm. Flagella have the same basic structure as CILIA but are longer in proportion to the cell bearing them and present in much smaller numbers. (From King & Stansfield, A Dictionary of Genetics, 4th ed)
Bacterial Proteins

The phylogenetic relationships of Caulobacter, Asticcacaulis and Brevundimonas species and their taxonomic implications. (1/72)

The phylogenetic relationships among the species of Caulobacter, Asticcacaulis and Brevundimonas were studied by comparison of their 16S rDNA sequences. The analysis of almost complete sequences confirmed the early evolutionary divergence of the freshwater and marine species of Caulobacter reported previously [Stahl, D. A., Key, R., Flesher, B. & Smit, J. (1992). J Bacteriol 174, 2193-2198]. The freshwater species formed two distinct clusters. One cluster contained the species Caulobacter bacteroides, Caulobacter crescentus, Caulobacter fusiformis and Caulobacter henricii. C. bacteroides and C. fusiformis are very closely related (sequence identity 99.8%). The second cluster was not exclusive and contained the specis Caulobacter intermedius, Caulobacter subvibrioides and Caulobacter variabilis, as well as Brevundimonas diminuta and Brevundimonas vesicularis. The marine species Caulobacter halobacteroides and Caulobacter maris were very closely related, with a sequence identity of 99.7%. These two species were most closely but distantly related to the marine hyphal/budding bacteria Hyphomonas jannaschiana and Hirschia baltica, which formed a deep phylogenetic line with Rhodobacter sphaeroides and Rhodobacter capsulatus. Caulobacter leidyia is unrelated to the other species of Caulobacter and belongs to the alpha-4 subclass of the Proteobacteria, forming a distinct cluster with Asticcacaulis excentricus and Asticcacaulis biprosthecium. The taxonomic implications of the polyphyletic nature of the genus Caulobacter and the absence of a type culture for the type species of the genus Caulobacter vibrioides, are discussed.  (+info)

Phylogeny and polyphasic taxonomy of Caulobacter species. Proposal of Maricaulis gen. nov. with Maricaulis maris (Poindexter) comb. nov. as the type species, and emended description of the genera Brevundimonas and Caulobacter. (2/72)

The genus Caulobacter is composed of prosthecate bacteria often specialized for oligotrophic environments. The taxonomy of Caulobacter has relied primarily upon morphological criteria: a strain that visually appeared to be a member of the Caulobacter has generally been called one without challenge. A polyphasic approach, comprising 16S rDNA sequencing, profiling restriction fragments of 16S-23S rDNA interspacer regions, lipid analysis, immunological profiling and salt tolerance characterizations, was used to clarify the taxonomy of 76 strains of the genera Caulobacter. Brevundimonas, Hyphomonas and Mycoplana. The described species of the genus Caulobacter formed a paraphyletic group with Caulobacter henricii, Caulobacter fusiformis, Caulobacter vibrioides and Mycoplana segnis (Caulobacter segnis comb. nov.) belonging to Caulobacter sensu stricto. Caulobacter bacteroides (Brevundimonas bacteroides comb. nov.), C. henricii subsp. aurantiacus (Brevundimonas aurantiaca comb. nov.), Caulobacter intermedius (Brevundimonas intermedia comb. nov.), Caulobacter subvibrioides (Brevundimonas subvibrioides comb. nov.), C. subvibrioides subsp. albus (Brevundimonas alba comb. nov.), Caulobacter variabilis (Brevundimonas variabilis comb. nov.) and Mycoplana bullata belong to the genus Brevundimonas. The halophilic species Caulobacter maris and Caulobacter halobacteroides are different from these two genera and form the genus Maricaulis gen. nov. with Maricaulis maris as the type species. Caulobacter leidyia was observed to cluster with species of the genus Sphingomonas. Caulobacter crescentus is synonymous with C. vibrioides and C. halobacteroides is synonymous with Maricaulis maris as determined by these analyses and DNA-DNA hybridization. Biomarkers discerning these different genera were determined. The necessary recombinations have been proposed and a description of Maricaulis is presented.  (+info)

Regulation of stalk elongation by phosphate in Caulobacter crescentus. (3/72)

In Caulobacter crescentus, stalk biosynthesis is regulated by cell cycle cues and by extracellular phosphate concentration. Phosphate-starved cells undergo dramatic stalk elongation to produce stalks as much as 30 times as long as those of cells growing in phosphate-rich medium. To identify genes involved in the control of stalk elongation, transposon mutants were isolated that exhibited a long-stalk phenotype irrespective of extracellular phosphate concentration. The disrupted genes were identified as homologues of the high-affinity phosphate transport genes pstSCAB of Escherichia coli. In E. coli, pst mutants have a constitutively expressed phosphate (Pho) regulon. To determine if stalk elongation is regulated by the Pho regulon, the Caulobacter phoB gene that encodes the transcriptional activator of the Pho regulon was cloned and mutated. While phoB was not required for stalk synthesis or for the cell cycle timing of stalk synthesis initiation, it was required for stalk elongation in response to phosphate starvation. Both pstS and phoB mutants were deficient in phosphate transport. When a phoB mutant was grown with limiting phosphate concentrations, stalks only increased in length by an average of 1.4-fold compared to the average 9-fold increase in stalk length of wild-type cells grown in the same medium. Thus, the phenotypes of phoB and pst mutants were opposite. phoB mutants were unable to elongate stalks during phosphate starvation, whereas pst mutants made long stalks in both high- and low-phosphate media. Analysis of double pst phoB mutants indicated that the long-stalk phenotype of pst mutants was dependent on phoB. In addition, analysis of a pstS-lacZ transcriptional fusion showed that pstS transcription is dependent on phoB. These results suggest that the signal transduction pathway that stimulates stalk elongation in response to phosphate starvation is mediated by the Pst proteins and the response regulator PhoB.  (+info)

Microbial community changes in biological phosphate-removal systems on altering sludge phosphorus content. (4/72)

Biomarkers (respiratory quinones and cellular fatty acids) and denaturing gradient gel electrophoresis (DGGE) of PCR-amplified 16S rRNA genes were used to characterize the microbial community structure of lab-scale enhanced biological phosphate-removal (EBPR) systems in response to altering sludge phosphorus (P) content. All the data suggest that the microbial community structures of sludge samples with a P content between 8 and 12.3% (sludge dry weight) (i.e. good EBPR activity) were very similar, but differed from those with 2% P content (i.e. no EBPR activity). For all samples analysed, ubiquinones Q-8 and Q-10, menaquinone MK-8(H4), and fatty acids C16:0, C16:1 omega9c and C18:1, omega11c were the major components. The dominance of Q-8, Q-10 and MK-8(H4) suggested that large numbers of organisms belonging to the beta and alpha subclasses of the Proteobacteria and the Actinobacteria from the high G+C Gram-positive bacteria, respectively, were present. DGGE analysis revealed at least 7-9 predominant DNA bands and numerous other fragments in each sample. Five major DGGE fragments from each of the 2% and 12% P-containing sludge samples, respectively, were successfully isolated and sequenced. Phylogenetic analysis of the sequences indicated that both 2% and 12% P-containing sludge samples shared three common phylotypes that were separately affiliated with a novel bacterial group from the gamma subclass of the Proteobacteria, two MK-8(H4)-containing actinobacteria previously isolated from the 2% P-containing sludge, and a Caulobacter spp. in the alpha subclass of the Proteobacteria. The phylogenetic analysis also revealed phylotypes unique to both sludge samples. Changes in sludge P content therefore had an effect on the composition and abundance of the predominant microbial populations, though specific phylotypes could not be unequivocally associated with EBPR.  (+info)

In situ reproductive rate of freshwater Caulobacter spp. (5/72)

Electron microscope grids were submerged in Lake Washington, Seattle, Wash., in June 1996 as bait to which Caulobacter sp. swarmers would attach and on which they would then reproduce in situ. Enumeration of bands in the stalks of attached cells implied that the caulobacters were completing approximately three reproductive cycles per day. A succession of morphological types of caulobacters occurred, as well as an episode of bacteriovore grazing that slowed the accumulation of caulobacters and prevented the aging of the population.  (+info)

Determination of the systematic position of the genus Asticcacaulis Poindexter by a polyphasic analysis. (6/72)

The genus Asticcacaulis, to date, comprises two species of unicellular, stalked bacteria, developing a stalk at a site which is not coincidental with the centre of the pole of the cell. Multiplication is similar to that demonstrated by the prosthecate species of the genera Caulobacter, Brevundimonas and Maricaulis. A polyphasic approach, comprising 16S rRNA gene sequencing, lipid analysis and NaCl tolerance characterizations, was used to clarify the taxonomy of the two Asticcacaulis species. From the analysis of the 16S rRNA gene sequences, a close phylogenetic relationship between the species that comprise the genera Asticcacaulis, Caulobacter and Brevundimonas could be deduced wherein the three genera form three distinct branches. The individual genera could also be discerned by different characteristic polar lipids. The species of Asticcacaulis differed from species of Caulobacter and Brevundimonas by the lack of 1,2-diacyl-3-O-[6'-phosphatidyl-alpha-D-glucopyranosyl]glycerol. They also did not contain 1,2-di-O-acyl-3-O-[D-glucopyranosyl-(1-->4)-alpha-D-glucuronopyranosyl]glycerol, which is found in most Brevundimonas species but not in strains of the genus Caulobacter. The morphological differences seen between the two species Asticcacaulis excentricus and Asticcacaulis biprosthecium are mirrored by the observed 16S rDNA sequence similarity value of 95.3%, which is relatively low compared to the interspecies similarity values observed within the genera Brevundimonas or Caulobacter.  (+info)

New members of the ctrA regulon: the major chemotaxis operon in Caulobacter is CtrA dependent. (7/72)

The Caulobacter crescentus che promoter region consists of two divergent promoters, directing expression of the major chemotaxis operon and a novel gene cagA (chemotaxis associated gene A). Analyses of start sites by primer extension and alignment of the divergent promoters revealed significant similarities between them at the -35 promoter region. Both mcpA and cagA are differentially expressed in the cell cycle, with maximal activation of transcription in predivisional cells. The main difference between the mcpA and cagA promoters is that, in common with the fljK flagellin, cagA is expressed in swarmer cells. A cagA--lacZ promoter fusion that contains 36 bases of untranslated mRNA has sufficient information to segregate the lacZ transcript to swarmer cells. Expression of mcpA and cagA was dependent on DNA replication. Transcriptional epistasis experiments were performed to identify potential regulators in the flagellar hierarchy. The sigma factor RpoN, which is required for flagellar biogenesis, is not required for mcpA and cagA expression. Mutations in the genes for the MS-ring and the switch complex (flagellar class II mutants) do not affect expression of mcpA and cagA. However, CtrA, an essential response regulator of flagellar gene transcription, is required.  (+info)

Genes directly controlled by CtrA, a master regulator of the Caulobacter cell cycle. (8/72)

Studies of the genetic network that controls the Caulobacter cell cycle have identified a response regulator, CtrA, that controls, directly or indirectly, one-quarter of the 553 cell cycle-regulated genes. We have performed in vivo genomic binding site analysis of the CtrA protein to identify which of these genes have regulatory regions bound directly by CtrA. By combining these data with previous global analysis of cell cycle transcription patterns and gene expression profiles of mutant ctrA strains, we have determined that CtrA directly regulates at least 95 genes. The total group of CtrA-regulated genes includes those involved in polar morphogenesis, DNA replication initiation, DNA methylation, cell division, and cell wall metabolism. Also among the genes in this notably large regulon are 14 that encode regulatory proteins, including 10 two-component signal transduction regulatory proteins. Identification of additional regulatory genes activated by CtrA will serve to directly connect new regulatory modules to the network controlling cell cycle progression.  (+info)

Caulobacter crescentus - WikipediaCaulobacter crescentus - Wikipedia
The Caulobacter cell cycle regulatory system controls many modular subsystems that organize the progression of cell growth and reproduction. A control system constructed using biochemical and genetic logic circuitry organizes the timing of initiation of each of these subsystems. The central feature of the cell cycle regulation is a cyclical genetic circuit-a cell cycle engine-that is centered around the successive interactions of five master regulatory proteins: DnaA, GcrA, CtrA, SciP, and CcrM whose roles were worked out by the laboratories of Lucy Shapiro and Harley McAdams.[8][9][10] These five proteins directly control the timing of expression of over 200 genes. The five master regulatory proteins are synthesized and then eliminated from the cell one after the other over the course of the cell cycle. Several additional cell signaling pathways are also essential to the proper functioning of this cell cycle engine. The principal role of these signaling pathways is to ensure reliable production ...

Role of Transcription in the Temporal Control of Development in Caulobacter crescentus | PNASRole of Transcription in the Temporal Control of Development in Caulobacter crescentus | PNAS
The requirement for transcription during development of the stalked bacterium, Caulobacter crescentus, was studied with synchronous cultures of swarmer cells. The developmental pattern in these bacteria was first established by determination of the times at which specific changes in cell structure and function occurred. These changes could be divided into those characteristic of (a) development of the swarmer cell into the stalked cell: loss of motility and synthesis of the stalk, and (b) development of the stalked cell into the asymmetric dividing cell: chromosome replication, synthesis of the flagellum, motility, and division. The effect of rifampin in blocking several of these steps-loss of motility, initiation of chromosome replication, and cell division-indicates that RNA synthesis is required throughout the cell cycle for normal differentiation.. ...

Factors controlling in vitro recrystallization of the Caulobacter crescentus paracrystalline S-layer. | Journal of BacteriologyFactors controlling in vitro recrystallization of the Caulobacter crescentus paracrystalline S-layer. | Journal of Bacteriology
The S-layer of Caulobacter is a two-dimensional paracrystalline array on the cell surface composed of a single protein, RsaA. We have established conditions for preparation of stable, soluble protein and then efficient in vitro recrystallization of the purified protein. Efficient recrystallization and long range order could not be obtained with pure protein only, though it was apparent that calcium was required for crystallization. Recrystallization was obtained when lipid vesicles were provided, but only when the vesicles contained the specific species of Caulobacter smooth lipopolysaccharide (SLPS) that previous studies implicated as a requirement for attaching the S-layer to the cell surface. The specific type of phospholipids did not appear critical; phospholipids rather different from those present in Caulobacter membranes or archaebacterial tetraether lipids worked equally well. The source of LPS was critical; rough and smooth variants of Salmonella typhimurium LPS as well as the rough ...

The structural maintenance of chromosomes (SMC) complex plays an important role in chromosome organization and segregation in most living organisms. In Caulobacter crescentus, SMC is required to align the left and the right arms of the chromosome that run in parallel down the long axis of the cell. However, the mechanism of SMC-mediated alignment of chromosomal arms remains elusive. Here, using genome-wide methods and microscopy of single cells, we show that Caulobacter SMC is recruited to the centromeric parS site and that SMC-mediated arm alignment depends on the chromosome-partitioning protein ParB. We provide evidence that SMC likely tethers the parS-proximal regions of the chromosomal arms together, promoting arm alignment. Furthermore, we show that highly transcribed genes near parS that are oriented against SMC translocation disrupt arm alignment, suggesting that head-on transcription interferes with SMC translocation. Our results demonstrate a tight interdependence of bacterial chromosome

The biochemical properties of the maltodextrin-hydrolyzing enzymes of cold-tolerant proteobacterium Caulobacter crescentus CB15 remain to be elucidated, although whose maltodextrin transport systems were well investigated. We cloned the putative glucoamylase of C. crescentus CB15 (CauloGA) gene. The CauloGA gene product that was expressed in E. coli was prone to forming inclusion bodies; however, most of the gene product was expressed in a soluble and active form when it was expressed as a fusion protein with Staphylococcus Protein A. The fusion protein was purified using an IgG Sepharose column and was identified as the active GA. The optimum temperature and pH for the activity of this GA toward maltotriose as a substrate were approximately 40°C and 5.0, respectively, and a differential scanning fluorimetry (DSF) analysis revealed that the melting temperature (Tm) of CauloGA was 42.9°C. The kinetic analyses with maltotriose and other maltodextrins as the substrates indicated that CauloGA has higher

ASMscience | Regulation of the CaulobASMscience | Regulation of the Caulob
This chapter focuses on the aquatic bacterium Caulobacter crescentus, which divides asymmetrically during each cell division cycle, yielding progeny cells that differ both structurally and functionally. The initially motile swarmer cell progeny sheds its flagellum and differentiates into a nonmotile stalked cell. In addition to morphological differences, the stalked- and swarmer cell progeny inherit different competencies for chromosome replication. A central component of any cell cycle is the initiation of chromosome replication coupled with strict controls to prevent repeated rounds of DNA replication without intervening cell divisions. The Caulobacter origin of replication was identified and cloned by taking advantage of the observation that replication is always initiated in the stalked cell. Microbial cells are able to monitor changes in their environment, detect changes in cell density, and communicate with each other and with other organisms through signals. The Caulobacter DnaA protein is a

Another factor that likely shapes the composition of the plant microbiome is interaction between microbes. In 2016, Eric Kemen of the Max Planck Institute for Plant Breeding Research and colleagues surveyed the microbes thriving in and on wild Arabidopsis leaves at five natural sites in Germany sampled in different seasons. They then plotted correlations between the abundances of more than 90,000 pairs of microbial genera identified in their survey, revealing six microbial hubs-nodes with significantly more connections than other nodes within the network. These hubs were represented by the oomycete genus Albugo, the fungal genera Udeniomyces and Dioszegia, the bacterial genus Caulobacter, and two distinct members of the bacterial order Burkholderiales.5 Given the high degree of connectivity within the communities, it is likely that these microbial hubs play a disproportionate role in the microbiome, akin to that of keystone species in an ecosystem ...

Cell Cycle Control of a Holdfast Attachment Gene inCaulobacter crescentus | Journal of BacteriologyCell Cycle Control of a Holdfast Attachment Gene inCaulobacter crescentus | Journal of Bacteriology
The holdfast is important for the attachment of C. crescentus cells to surfaces; however, little is known about the regulation of holdfast synthesis and holdfast attachment genes during the cell cycle. Furthermore, the time of holdfast appearance at the pole of the cell is not known. In this paper, we investigate two aspects of holdfast synthesis: the transcription of a holdfast attachment gene, hfaA, and the appearance of the holdfast at the pole of the cell. We demonstrate that hfaA transcription is temporally controlled during the cell cycle, with maximal transcription in the swarmer pole of the predivisional cell. We show that the holdfast is not present in swarmer cells or at the swarmer poles of predivisional cells. Our results suggest that the holdfast appears during the differentiation of swarmer to stalked cells.. The hfaA gene possesses a ς54 promoter sequence at the requisite distance from the transcription start site (16). However, our results indicate that hfaA is not transcribed ...

Nanotechnology Now - Press Release: How Do Bacteria Swim? Brown Physicists ExplainNanotechnology Now - Press Release: How Do Bacteria Swim? Brown Physicists Explain
Caulobacter is a single-celled organism with a filament-like tail called a flagellum. As it swims, its rounded cellular head rotates in one direction, while the tail rotates in the opposite direction. This creates torque, which helps explain the bacteriums nonlinear movement through a fluid. What Tang and his team found, however, is that Caulobacter also is influenced by Brownian motion, which is the zigzagging motion that occurs when immersed particles are buffeted by the actions of the molecules of the surrounding medium. What that means, in effect, is that Caulobacter is being pinballed by the water molecules surrounding it as it swims ...

Dynamics and control of biofilms of the oligotrophic bacterium Caulobacter crescentus. | Alfred M. Spormann LaboratoryDynamics and control of biofilms of the oligotrophic bacterium Caulobacter crescentus. | Alfred M. Spormann Laboratory
Caulobacter crescentus is an oligotrophic alpha-proteobacterium with a complex cell cycle involving sessile-stalked and piliated, flagellated swarmer cells. Because the natural lifestyle of C. crescentus intrinsically involves a surface-associated, sessile state, we investigated the dynamics and control of C. crescentus biofilms developing on glass surfaces in a hydrodynamic system. In contrast to biofilms of the well-studied Pseudomonas aeruginosa, Escherichia coli, and Vibrio cholerae, C. crescentus CB15 cells form biphasic biofilms, consisting predominantly of a cell monolayer biofilm and a biofilm containing densely packed, mushroom-shaped structures. Based on comparisons between the C. crescentus strain CB15 wild type and its holdfast (hfsA; DeltaCC0095), pili (DeltapilA-cpaF::Omegaaac3), motility (motA), flagellum (flgH) mutants, and a double mutant lacking holdfast and flagellum (hfsA; flgH), a model for biofilm formation in C. crescentus is proposed. For both biofilm forms, the holdfast ...

Cryoelectron microscope tomography (cryoEM) and a fluorescence loss in photobleaching (FLIP) assay were used to characterize progression of the terminal stages of Caulobacter crescentus cell division. Tomographic cryoEM images of the cell division site show separate constrictive processes closing first the inner membrane (IM) and then the outer membrane (OM) in a manner distinctly different from that of septum-forming bacteria. FLIP experiments had previously shown cytoplasmic compartmentalization (when cytoplasmic proteins can no longer diffuse between the two nascent progeny cell compartments) occurring 18 min before daughter cell separation in a 135-min cell cycle so the two constrictive processes are separated in both time and space. In the very latest stages of both IM and OM constriction, short membrane tether structures are observed. The smallest observed pre-fission tethers were 60 nm in diameter for both the inner and outer membranes. Here, we also used FLIP experiments to show that ...

Second messenger-mediated spatiotemporal control of protein degradation regulates bacterial cell cycle progression - edocSecond messenger-mediated spatiotemporal control of protein degradation regulates bacterial cell cycle progression - edoc
Second messengers control a wide range of important cellular functions in eukaryotes and prokaryotes. Here we show that cyclic di-GMP, a global bacterial second messenger, promotes cell cycle progression in Caulobacter crescentus by mediating the specific degradation of the replication initiation inhibitor CtrA. During the G1-to-S-phase transition, both CtrA and its cognate protease ClpXP dynamically localize to the old cell pole, where CtrA is rapidly degraded. Sequestration of CtrA to the cell pole depends on PopA, a newly identified cyclic di-GMP effector protein. PopA itself localizes to the cell pole and directs CtrA to this subcellular site via the direct interaction with a mediator protein, RcdA. We present evidence that c-di-GMP regulates CtrA degradation during the cell cycle by controlling the dynamic sequestration of the PopA recruitment factor to the cell pole. Furthermore, we show that cell cycle timing of CtrA degradation relies on converging pathways responsible for substrate and ...

My research interests include Bacterial Cell Cycle Regulation and Signal Transduction mechanisms.. 1. Bacterial Cell Cycle Regulation- Epigenetic mechanisms regulating various physiological activities in the prokaryotic cells are increasingly being appreciated. Methylation of specific bases of the DNA molecule by methyltransferases is the most common epigenetic modification observed in the bacterial cells. This modification of nucleotides adds another level of regulation at the transcription; furthermore, it has a fundamental role in the cell physiological processes such as DNA replication, DNA mismatch repair, and virulence mechanisms in many pathogens. Among the prokaryotic DNA methyltransferases, Dam expressed among the Gammaproteobacteria is the most intensively studied. In contrast to Dam, another DNA methyltransferase CcrM (Cell Cycle Regulated Methylase) has been described in the Alphaproteobacteria, where it plays an important role in the cell cycle regulation of Caulobacter crescentus ...

In Caulobacter crescentus, the temporal and spatial expression of late flagellar genes is regulated by the 54 transcriptional activator, FlbD. Genetic experiments have indicated that the trans-acting factor FliX regulates FlbD in response to the progression of flagellar assembly, repressing FlbD activity until an early flagellar basal body structure is assembled. Following assembly of this structure, FliX is thought to function as an activator of FlbD. Here we have investigated the mechanism of FliX-mediated regulation of FlbD activity. In vitro transcription experiments showed that purified FliX could function as a repressor of FlbD-activated transcription. Transcription activated by a gain-of-function mutant of FlbD (FlbD-1204) that is active in vivo in the absence of an early flagellar structure, was resistant to the repressive effects of FliX. DNA binding studies showed that FliX inhibited the interaction of wild-type FlbD with enhancer DNA but did not effect FlbD-catalysed ATPase ...

Deaths in the family cause bacteria to flee: IU News Room: Indiana UniversityDeaths in the family cause bacteria to flee: IU News Room: Indiana University
The deaths of nearby relatives have a curious effect on the bacterium Caulobacter crescentus -- surviving cells lose their stickiness. Indiana University Bloomington biologists report in an upcoming issue of Molecular Microbiology that exposure to the extracellular DNA (eDNA) released by dying neighbors stops the sticky holdfasts of living Caulobacter from adhering to surfaces, preventing cells from joining bacterial biofilms. Less sticky cells are more likely to escape established colonies, out to where conditions may be better.

Small Things Considered: A PomZ Scheme For Turning One Cell Into TwoSmall Things Considered: A PomZ Scheme For Turning One Cell Into Two
By William Margolin | The division of one cell into two daughter cells is the crux of biological reproduction. But how do cells determine where along their dimensions division will occur? For bacteria, the best-studied species for basic biology, including cytokinesis, are the old standbys Escherichia coli, Bacillus subtilis, and Caulobacter crescentus, mainly because of their easy cultivation…
