Ralstonia
''Ralstonia'' is a genus of bacteria, previously included in the genus ''Pseudomonas''. It is named after the American bacteriologist Ericka Ralston. Ericka Ralston was born Ericka Barrett in 1944 in Saratoga, California, and died in 2015 in Sebastopol, California. While in graduate school at the University of California at Berkeley, she identified 20 strains of ''Pseudomonas'' which formed a phenotypical homologous group, and named them ''Pseudomonas pickettii'', after M.J. Pickett in the Department of Bacteriology at the University of California at Los Angeles, from whom she had received the strains. Later, ''P. pickettii'' was transferred to the new genus ''Ralstonia'', along with several other species. She continued her research into bacterial pathogenesis under the name of Ericka Barrett while a professor of microbiology at the University of California at Davis from 1977 until her retirement in 1996.

Ralstonia Solanacearum
''Ralstonia solanacearum'' is an aerobic non-spore-forming, Gram-negative, plant pathogenic bacterium. ''R. solanacearum'' is soil-borne and motile with a polar flagellar tuft. It colonises the xylem, causing bacterial wilt in a very wide range of potential host plants. It is known as Granville wilt when it occurs in tobacco. Bacterial wilts of tomato, pepper, eggplant, and Irish potato caused by ''R. solanacearum'' were among the first diseases that Erwin Frink Smith proved to be caused by a bacterial pathogen. Because of its devastating lethality, ''R. solanacearum'' is now one of the more intensively studied phytopathogenic bacteria, and bacterial wilt of tomato is a model system for investigating mechanisms of pathogenesis. ''Ralstonia'' was until recently classified as ''Pseudomonas'', with similarity in most aspects, except that it does not produce fluorescent pigment like ''Pseudomonas''. The genomes from different strains vary from 5.5 Mb up to 6 Mb, roughly being 3.5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ralstonia Pickettii
''Ralstonia pickettii'' is a Gram-negative, rod-shaped, soil bacterium. ''Ralstonia pickettii'' is a Betaproteobacteria species found in moist environments such as soils, rivers, and lakes. It has also been identified in biofilms in plastic water pipes. It is an oligotrophic organism, making it capable of surviving in areas with a very low concentration of nutrients. Several strains have shown an ability to survive in environments highly contaminated with metals. The ability to persist in these harsh conditions makes ''R. pickettii'' a candidate for bioremediation. ''Ralstonia pickettii'' and ''R. insidiosa'' are emerging pathogens in hospital settings. ''R. pickettii'' pathology does not follow an easy definition; although no fully healthy human has ever become ill from it, the bacterium has seriously affected humans with poor health. Several hospitals have reported outbreaks—in particular, patients with cystic fibrosis and Crohn's disease have been shown to be infected wi ...

Ralstonia Pseudosolanacearum
''Ralstonia pseudosolanacearum'' is a soil-borne bacterium. It is a vascular phytopathogen that infects host plants through the root system causing wilting disease that causes loss in a wide range of crops. ''R. pseudosolanacearum'' is Gram negative and was originally identified as ''Ralstonia solanacearum,'' however, in 2014 Safni et al. proposed a taxonomic revision of the ''Ralstonia solanacearum'' species complex to reclassify phylotype strains, including ''R. pseudosolanacearum'' (''R. solanacearum'' Phylotype I and III)''.'' ''R. pseudosolanacearum'' has been reported in a wide variety of crops including ornamental roses (''Rosa sp.)'', tomato (''Solanum lycopersicum), sweet pepper (Capsicum'' ''annum'') and eggplant (''Solanum melongena).'' Recent studies have found significant differences in disease severity influenced by higher temperatures (28°C) indicating temperature may be a virulence factor upon host colonization. The same study also reported wound inoculation res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pseudomonas
''Pseudomonas'' is a genus of Gram-negative, Gammaproteobacteria, belonging to the family Pseudomonadaceae and containing 191 described species. The members of the genus demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. Their ease of culture ''in vitro'' and availability of an increasing number of ''Pseudomonas'' strain genome sequences has made the genus an excellent focus for scientific research; the best studied species include '' P. aeruginosa'' in its role as an opportunistic human pathogen, the plant pathogen '' P. syringae'', the soil bacterium '' P. putida'', and the plant growth-promoting ''P. fluorescens, P. lini, P. migulae'', and ''P. graminis''. Because of their widespread occurrence in water and plant seeds such as dicots, the pseudomonads were observed early in the history of microbiology. The generic name ''Pseudomonas'' created for these organisms was defined in rather vague terms by Walter Migula ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulp ...

United States Department Of Energy
The United States Department of Energy (DOE) is an executive department of the U.S. federal government that oversees U.S. national energy policy and manages the research and development of nuclear power and nuclear weapons in the United States. The DOE oversees the U.S. nuclear weapons program, nuclear reactor production for the United States Navy, energy-related research, and domestic energy production and energy conservation. The DOE was created in 1977 in the aftermath of the 1973 oil crisis. It sponsors more physical science research than any other U.S. federal agency, the majority of which is conducted through its system of National Laboratories. The DOE also directs research in genomics, with the Human Genome Project originating from a DOE initiative. The department is headed by the Secretary of Energy, who reports directly to the president of the United States and is a member of the Cabinet.

Integrated Microbial Genomes System
The Integrated Microbial GenomesIMG system is a genome browsing and annotation platform developed by the U.S. Department of Energy (DOE)- Joint Genome Institute. IMG contains all the draft and complete microbial genomes sequenced by the DOE-JGI integrated with other publicly available genomes (including Archaea, Bacteria, Eukarya, Viruses and Plasmids). IMG provides users a set of tools for comparative analysis of microbial genomes along three dimensions: genes, genomes and functions. Users can select and transfer them in the comparative analysis carts based upon a variety of criteria. IMG also includes a genome annotation pipeline that integrates information from several tools, including KEGG, Pfam, InterPro, and the Gene Ontology, among others. Users can also type or upload their own gene annotations (called MyIMG gene annotations) and the IMG system will allow them to generate Genbank or EMBL format files containing these annotations. In successive releases IMG has expanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
