| the phylogenetic relationships of caulobacter, asticcacaulis and brevundimonas species and their taxonomic implications. | 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 bacter ... | 1999 | 10319468 |
| 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. | 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 ... | 1999 | 10425763 |
| phylogeny by a polyphasic approach of the order caulobacterales, proposal of caulobacter mirabilis sp. nov., phenylobacterium haematophilum sp. nov. and phenylobacterium conjunctum sp. nov., and emendation of the genus phenylobacterium. | three strains of gram-negative, rod-shaped, non-spore-forming bacteria were isolated from fresh water and human blood. as determined by analyses of 16s rrna gene sequences, the prosthecate strain fwc 38t was affiliated to the alphaproteobacterial genus caulobacter, with caulobacter henricii (96.8 %) and caulobacter fusiformis (96.8 %) as its closest relatives. the non-prosthecate strain lmg 11050t and the prosthecate strain fwc 21t both belonged to the genus phenylobacterium with phenylobacteriu ... | 2008 | 18676485 |
| caulobacter ginsengisoli sp. nov., a novel stalked bacterium isolated from ginseng cultivating soil. | a gram negative, aerobic, nonspore-forming, straight or curved rod-shaped bacterium, designated gsoil 317t, was isolated from soil of a ginseng field in pocheon province (south korea) and was characterized using a polyphasic approach. cells were dimorphic, with stalk (or prostheca) and nonmotile or nonstalked and motile, by means of a single polar flagellum. comparative analysis of 16s rrna gene sequences revealed that strain gsoil 317t was most closely related to caulobacter mirabilis lmg 24261 ... | 2010 | 20134228 |
| conservation of the essential genome among caulobacter and brevundimonas species. | when the genomes of caulobacter isolates na1000 and k31 were compared, numerous genome rearrangements were observed. in contrast, similar comparisons of closely related species of other bacterial genera revealed nominal rearrangements. a phylogenetic analysis of the 16s rrna indicated that k31 is more closely related to caulobacter henricii cb4 than to other known caulobacters. therefore, we sequenced the cb4 genome and compared it to all of the available caulobacter genomes to study genome rear ... | 2016 | 26750121 |
| caulobacter flavus sp. nov., a stalked bacterium isolated from rhizosphere soil. | a gram-stain-negative, aerobic, yellow-pigmented and rod-shaped bacterium with a single polar flagellum or a stalk, designated strain rhgg3t, was isolated from rhizosphere soil of cultivated watermelon (citrullus lanatus) collected from hefei, china. optimal growth of strain rhgg3t was observed at ph 7.0 and 28-30 °c. cells were catalase-positive and oxidase-negative. phylogenetic analysis based on 16s rrna gene sequences indicated that strain rhgg3t belonged to the genus caulobacter and showed ... | 2015 | 26354335 |
| comparison of genome sequencing technology and assembly methods for the analysis of a gc-rich bacterial genome. | improvements in technology and decreases in price have made de novo bacterial genomic sequencing a reality for many researchers, but it has created a need to evaluate the methods for generating a complete and accurate genome assembly. we sequenced the gc-rich caulobacter henricii genome using the illumina miseq, roche 454, and pacific biosciences rs ii sequencing systems. to generate a complete genome sequence, we performed assemblies using eight readily available programs and found that builds ... | 2015 | 25377284 |
