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)

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.. ...
TY - JOUR. T1 - Use of transmissible plasmids as cloning vectors in Caulobacter crescentus. AU - Schoenlein, Patricia V. AU - Gallman, Lilly M.. AU - Ely, Bert. PY - 1988/10/30. Y1 - 1988/10/30. N2 - Cloning vectors for studies of Caulobacter crescentus genes should be transferable between Escherichia coli and C. crescentus since a transformation system has not been developed for C. crescentus. We have tested a large number of vectors containing IncP or IncQ replicons and found that many of the vectors containing IncQ replicons, and all but one of the vectors containing IncP replicons, are readily transferred by conjugation into C. crescentus. All of the plasmids tested were maintained in C. crescentus at 1 to 5 copies per cell, but plasmids containing IncP replicons were more stable than plasmids containing IncQ replicons. Further studies with a derivative of the IncQ plasmid R300B showed that when a promoterless kanamycin (Km)-resistance gene (npt2) was inserted into the intercistronic region ...
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

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 ...
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 ...
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 ...

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 ...

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 ...

The Brevundimonas are a genus of proteobacteria. They are Gram-negative, non-fermenting, aerobic bacilli. The Brevundimonas species are ubiquitous in the environment but are rarely isolated from clinical samples. Two species of Brevundimonas originally classified under the genus Pseudomonas have been re-classified by Seger et al. as Brevundimonas vesicularis and Brevundimonas diminuta. The name Brevundimonas derives from: Latin adjective brevis, short; Latin feminine gender noun unda, a wave; Latin feminine gender noun monas (μονάς / μονάδα), nominally meaning "a unit", but in effect meaning a bacterium; New Latin feminine gender noun Brevundimonas, bacteria with short wavelength flagella. Members of the genus Brevundimonas can be referred to as brevundimonad (viz. Trivialisation of names). Brevundimonas is one of few bacteria showing high survival rates under simulated Martian conditions. Results from one of these experimental irradiation experiments, combined with previous radiation ...
Genome analysis identified a large number of genes that would enable utilization of dilute carbon sources and provides a comprehensive picture of the strategies used by C. crescentus for survival in nutrient-limiting conditions. Unlike E. coli and Vibrio cholerae, C. crescentus has no OmpF-type outer membrane porins that allow the passive diffusion of hydrophilic substrates across the outer membrane. However, it does possess 65 members of the family of TonB-dependent outer membrane channels that catalyze energy-dependent transport across the outer membrane. This is more than any other organism thus far characterized, with the next highest being 34 in Pseudomonas aeruginosa (32), and with no other sequenced proteobacteria possessing more than 10. C. crescentus has substantially fewer cytoplasmic membrane transporters relative to genome size than either E. coli or V. cholerae (33). Given C. crescentus low nutrient habitat, it is surprising that PTS or ATP-binding cassette domain transporters, ...
The citrate cycle (TCA cycle, Krebs cycle) is an important aerobic pathway for the final steps of the oxidation of carbohydrates and fatty acids. The cycle starts with acetyl-CoA, the activated form of acetate, derived from glycolysis and pyruvate oxidation for carbohydrates and from beta oxidation of fatty acids. The two-carbon acetyl group in acetyl-CoA is transferred to the four-carbon compound of oxaloacetate to form the six-carbon compound of citrate. In a series of reactions two carbons in citrate are oxidized to CO2 and the reaction pathway supplies NADH for use in the oxidative phosphorylation and other metabolic processes. The pathway also supplies important precursor metabolites including 2-oxoglutarate. At the end of the cycle the remaining four-carbon part is transformed back to oxaloacetate. According to the genome sequence data, many organisms seem to lack genes for the full cycle [MD:M00009], but contain genes for specific segments [MD:M00010 M00011 ...
The correct functioning of cells requires the orchestration of multiple cellular processes, many of which are inherently dynamical. The conditions under which these dynamical processes entrain each other remain unclear. Here we use synthetic biology to address this question in the case of concurrent cellular oscillations. Specifically, we study at the single-cell level the interaction between the cell division cycle and a robust synthetic gene oscillator in Escherichia coli. Our results suggest that cell division is able to partially entrain the synthetic oscillations under normal growth conditions, by driving the periodic replication of the genes involved in the oscillator. Coupling the synthetic oscillations back into the cell cycle via the expression of a key regulator of chromosome replication increases the synchronization between the two periodic processes. A simple computational model allows us to confirm this effect ...
C. crescentus undergoes a developmental step during its division cycle from a motile cell unable to replicate its DNA to a nonmotile cell that is competent for chromosome replication. We use synchronized populations of motile G1-phase cells to study the events that occur during development. C. crescentus also divides asymmetrically, producing one motile and one nonmotile cell at each division. Proteins in the predivisional cell are segregated to opposite ends to mediate the differentiation of identity after division. We study the locations and movements of individual proteins using fluorescence microscopy.. Specific problems that we are investigating include the following: regulated degradation of a key transcription factor during the motile-sessile developmental step; the roles, locations, and interactions of enzymes that participate in cell wall biosynthesis; and the regulatory functions of protein phosphorylation on serine, threonine, or tyrosine residues. ...
Virginia Tech scientists have developed a quantitative, mathematical model of DNA replication and cell division for the bacterium Caulobacter crescentus.
I will discuss our recent work that combined single-molecule imaging, fluorescence-recovery-after-photobleaching and optical tweezers to determine how the flagellar motor senses mechanical signals. I will present data that provides evidence that the chemotactic output of a molecular switch within the motor is influenced by the response to perturbations in viscous loads. The switch changes the direction of motorrotation and the torque generated is anisotropic. Yet, Caulobacter Crescentus cells that carry a single rigid flagellum, unlike E. coli cells that carry many, swim with similar speeds in the forward and backward directions. The resulting paradox that arises due to the time-reversibility of Stokes flow can be resolved with a simple model that incorporates cell-precession during swimming. Our observations indicate that motor mechanics are similar between the two species belonging to different classes of bacteria, and suggest that motor-mechanosensing might also be conserved. I will conclude ...
I would hate to see G+ being shot down in flames but I get the impression that if something doesnt take off immediately with Google they terminate with extreme prejudice! Some things take time!

In fact, it was only in the late 1990s that biologists discovered bacteria even had a cytoskeleton. The cytoskeleton was first identified in the cells of eukaryotic organisms (those, such as plants and animals, whose cells have specialized organelles and a discrete nucleus). Bacteria are tiny, for one thing, and until the advent of advanced imaging technology, scientists could not get a good look inside. The species Goley studies, Caulobacter crescentus, is a mere 500 nanometers across, or about one one-hundredth the size of an average human cell.. Second, a cell wall encases most bacterial species, and scientists assumed this semi-rigid structure obviated the need for a cytoskeleton.. These assumptions turned out to be wrong. In 1998, structural biologist Jan Löwe, in the United Kingdom, demonstrated that a bacterial protein called FtsZ is an evolutionary counterpart of tubulin, a key protein component of the eukaryote cytoskeleton. The finding implied that the cytoskeleton was not a ...

ChIP-Chip stands for Chromatin Immunoprecipitation and chip in the sense of DNA microarray. It is a technique to determine the genome-wide binding sites of a DNA-binding protein. While the basic principle is the same for all species, there are some differences in handling cells. This protocol is developed and tested for E. coli. It should work the same way for other bacteria but that remains to be proven. Published protocols also exist for other bacterial species, including Bacillus subtilis, Caulobacter crescentus and Mycobacterium tuberculosis. Because E. coli can be grown to high cell densities relative to eukaryotes, it is possible to generate sufficient DNA to label without using a PCR-based method [1]. This method uses strand displacement primer extension with Klenow DNA polymerase and amplifies the DNA ~10-fold, while simultaneously incorporating dye-coupled nucleotide. Related protocols can be found here: ...
It is thought that S-layers protect cells from phages and large molecules. Using a combination of cellular electron cryo tomography (cryo-ET) with subtomogram averaging and X-ray crystallography we have determined the structure of the complete and intact S-layer lattice on Gram negative Caulobacter crescentus cells. We showed that the lattice formed in the crystals matches perfectly the lattice formed on cells as determined at 7.4 Å, directly on cells ...

Small, low-flying airplanes buzzing over fields and timber are a familiar and necessary cog in the wheels of agriculture and the timber industry. Sometimes their movements are as entertaining as stunt fliers. Their services, however, are anything but frivolous. "Spraying is very important to agriculture. Insects can put you out of business. It`s as simple as that," said Will Green Poindexter, executive director of the Mississippi Agriculture Aviation Association (MAAA) headquartered in Inverness. "Spraying must be done in a timely fashion. Insects build and a farmer can`t miss a cycle.". Immediately following the September 11 tragedy, crop dusting planes with their ominous-looking white substances were suspicious and grounded for two weeks. This timing hurt agriculture tremendously, Green said.. "September is a very important time for agriculture because that`s when crops are foliated," he said. "Everything is different now and we think about it differently. We never worried before.". Gary ...
The decoding of genetic information into protein sequence relies upon the interaction of messenger RNA (mRNA), which contains information in the form of a string of three-nucleotide codons, and transfer RNA (tRNA), which contains complementary anticodons at one end and the designated amino acid at the other. In bacteria, a quality control system utilizes a hybrid molecule known as tmRNA that binds to ribosomes lodged on a defective mRNA. The alanine residue of tmRNA accepts the incomplete protein, and the ribosome then switches over to begin translating a portion of the tmRNA that encodes a tag that targets the finished (but defective) protein for proteolytic degradation.. Keiler et al. describe the identification of a circularly permuted, two-piece tmRNA in Caulobacter. This bipartite RNA species is functional, and similar sequences are found in cyanobacteria and Rickettsia and even the mitochondrion of the protist Reclinomonas. Not only does this finding open a new door to studying the ...

The virus attaches to the pili, sometimes the virion receptor site, and transiently exposes viral RNA while penetrating the cell [2]. The family Leviviridae is found to have one of the fastest known mutation rates, at 10-3 bp/replication, but also one of the smallest genomes at 4,268 nt which code for 4 protein subunits [3]. The distinguishing factor of levivirus is a cell-lysis protein coded within its genome, something that is absent in allelovirus. In 1976 the species Enterobacteria phage MS2 became the first organism ever to have ...

In response to DNA damage, eukaryotic cells initiate a complex signalling pathway, termed the DNA damage response (DDR), which coordinates cell cycle arrest with DNA repair. Studies have shown that oncogene-induced senescence, which provides a barrier to tumour development, involves activation of the DDR. Using a genome-wide RNA interference (RNAi) screen, we have identified 17 factors required for oncogenic BRAF to induce senescence in primary fibroblasts and melanocytes. One of these factors is an F-box protein, FBXO31, a candidate tumour suppressor encoded in 16q24.3, a region in which there is loss of heterozygosity in breast, ovarian, hepatocellular and prostate cancers. Here we study the cellular role of FBXO31, identify its target substrate and determine the basis for its growth inhibitory activity. We show that ectopic expression of FBXO31 acts through a proteasome-directed pathway to mediate the degradation of cyclin D1, an important regulator of progression from G1 to S phase, resulting in
How did life begin? For those who reject the testimony of Genesis, the search is restricted to clues in nature.. One such clue is the minimum essentials required for growth and reproduction. If that number is small enough, then life might conceivably have formed by chance.. The 2008 documentary movie Expelled: No Intelligence Allowed presented 250 proteins as an estimated minimum required for cell function. The odds of that many forming by chance was equated to a man winning at a slot machine 250 consecutive times.. But the real odds are much more staggering. Molecular biologist Doug Axe said, "Were talking about something thats staggeringly improbable: roughly one in a trillion trillion trillion trillion trillion trillion."1 Based on new research, Axe may have to quadruple those already impossible odds.. A team of biologists at the Stanford University School of Medicine employed a new method to estimate the minimum genetic information required for the survival of bacteria called Caulobacter ...

  • From left to right: i) The number of proteins in the reference proteome of Caulobacter crescentus , ii) the total number of models, iii) the number of unique protein sequences for which at least one model is available and iv) a coverage bar plot is shown. (expasy.org)
  • The bar plot shows the coverage for every protein in the reference proteome of Caulobacter crescentus for which there is at least one model. (expasy.org)
  • Three-dimensional superresolution colocalization of intracellular protein superstructures and the cell surface in live Caulobacter crescentus. (mendeley.com)
  • Caulobacter is really easy to culture and electroporate, and secretes a scum of solid protein that can be skimmed off the top of the culture medium, but that scum has the target covalently fused to a signal sequence. (igem.org)
  • Caulobacter is an alpha-proteobacterium that always divides asymmetrically to generate two daughter cells that are morphologically distinct and have different replicative capacities. (mit.edu)
  • Almqvist H, Jonsdottir Glaser S, Tufvegren C, Wasserstrom L, Lidén G. Characterization of the Weimberg Pathway in Caulobacter crescentus . (mdpi.com)
  • Then, a new route for glycolate production was established in E . coli by introducing NAD + -dependent xylose dehydrogenase ( xdh ) and xylonolactonase ( xylC ) from Caulobacter crescentus . (springer.com)
  • Analysis of the dynamics of TrfA- complex formation during the Caulobacter cell cycle revealed that TrfA binds primarily during the G1 phase, however plasmid DNA synthesis occurs during the S and G2 phases of the cell cycle. (unibas.ch)
  • To explore these questions, she is using the crescent-shaped Caulobacter, a non-pathogenic resident of freshwater lakes and streams. (hopkinsmedicine.org)
  • Here, we dissect the c-di-GMP network of Caulobacter crescentus to establish a global and quantitative view of c-di-GMP dependent processes in this organism. (harvard.edu)
  • Mutations in highly conserved regions of FliX could severely affect the recognition between FliX and FlbD and hence interrupt the normal progression of flagellar synthesis and other developmental events in Caulobacter . (beds.ac.uk)
  • However, our studies show that it likely does not play such a role in Caulobacter as depleting PhoU has no significant effect on PhoB-dependent gene expression. (datamed.org)
  • During their study, the scientists found a new technique to observe and film Caulobacter crescentus pili undergoing dynamic cycles of extension and retraction. (eurekalert.org)
  • This twin effect of hydrodynamic interaction and Brownian motion governs the circular swimming patterns of Caulobacter and many other microorganisms, the scientists found. (nanotech-now.com)
  • The Caulobacter Phage Holin (CauHol) Family (TC# 1.E.47) consists of several putative holins of 157 to 159 amino acyl residues (aas) in length that exhibit 2 transmembrane segments (TMSs). (wikipedia.org)
  • In Caulobacter crescentus , c-di-GMP regulates the synthesis of the polar holdfast adhesin during the cell cycle, yet the molecular and cellular details of this control are currently unknown. (asm.org)
