Archaea in fact differ from bacteria in both their genetics and biochemistry. Google Scholar. 2007, 143 (2): 587-599. Nat Biotechnol. When two strains are compared, one is shown in red, another in green, and the overlap in yellow. In turn, this led to the observation and enumeration of groups of proteins regulated in a common way, the so-called regulons. One is in the area of systems biology, the topic of this special issue. PubMedGoogle Scholar. Google Scholar. Twenty-seven of the 78 knockouts gave clear phenotypes, and of these only 12 (44%) precisely matched the predicted annotation. . 4. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Only about 9000 bacterial species have been described and named (http://www.bacterio.cict.fr/number.html the number of named fungal species is about 10 times higher) but the actual number of species on Earth has been estimated to be in the range of 105109. Systems biologists are attempting to make computerized models that accurately mimic behaviors of a cell and, more importantly, to predict behaviors that may not be apparent. The first version of OMP was released in June 2011 on the OMP projects development site [17], and new versions are released on a regular basis. Re-use of this article is permitted in accordance with the Creative Commons Deed, Attribution 2.5, which does not permit commercial exploitation. [[40]]. Systems biology seeks to model the cell as closely as possible and in its entirety (Ishii, 2007). PMs are sets of phenotypic assays performed in 96-well microplates. 10.1093/nar/gkj068. CAS MC, MG, JHu, and DS wrote the manuscript. A striking example of different regulation is shown by the comparison of E. coli to Staphylococcus aureus in Fig. In my opinion, systems biology models would benefit greatly if they were more carefully and clearly organized around concepts of physiology and implemented with a physiological core structure. By inoculating a microbial strain into the 1920 wells of a PM and incubating for a sufficient period of time, one can quickly and easily create 1920 different versions of their cell of interest. Phenotypic testing is also universally applicable (to culturable microorganisms) and taxonomically predictive, and in addition it provides useful information about the biological properties of cells. This horizontal gene transfer, coupled with a high mutation rate and many other means of genetic variation, allows microorganisms to swiftly evolve (via natural selection) to survive in new environments and respond to environmental stresses. This imbalance in excessive NADH and NADPH would be a logical molecular alarm signal to indicate to the cell that it is producing more energy than it can use and thereby provide the checkpoint signal to stop unneeded and potentially harmful generation of excessive reducing power. The one systematic attempt to use PM technology to assess the accuracy of current genome annotation is the work of Paulsen and colleagues (Johnson, 2008). Therefore, growth phenotypes are directly and intimately involved in fundamental aspects of cellular genome and organism evolution and they remain a cornerstone of microbial taxonomy. Microorganisms can be classified on the basis of cell structure, cellular metabolism, or on differences in cell components. The existence of so many bacterial species reflects the presence of so many environmental niches on Earth and the resourcefulness of life forms to evolve to live in them. Terms from respective ontologies are rendered in different color type: BFO, black; PATO, blue; GO, red; and OMP, purple. We have avoided the use of the qualifier abnormal for two reasons: there can be no consistent definition of what is normal or abnormal across organisms, and altered_relative_to is superior for capturing phenotypes of genetic modifiers such as suppressors and enhancers [28]. 2007, 23 (16): 2198-2200. 2014, 2014: bau075-10.1093/database/bau075. Analysis of the range of these suppressor mutations restoring good growth has been a proven method to accurately expand our knowledge of gene function, protein and pathway interactions, and microbial biology. 2012, 40 (Database issue): D1262-D1269. 10.1093/bioinformatics/btt266. Understanding how phenotypes emerge from genotypes is a foundational goal in biology. Example annotations of chemotaxis phenotypes reported by Hazelbauer, et al. In fact, Vazquez-Boland and colleagues have found that it may be the essential C-source. For full access to this pdf, sign in to an existing account, or purchase an annual subscription. Curr Opin Biotechnol. By using this website, you agree to our Assays of ion, pH, and chemical sensitivities provide information on stress and repair pathways that are present and active in cells. It should be possible, by comparing the phenotypes of uninfected vs. infected mammalian cells, to gain information about how infection with a microorganism alters the biology of the host cell. Diverse pathogens have been analyzed, including E. coli, Salmonella enterica, P. aeruginosa and Pseudomonas syringae, Enterobacter (now Cronobacter) sakazakii, Yersinia pestis, Vibrio cholerae, Campylobacter jejuni, Helicobacter pylori, S. aureus, Listeria monocytogenes, Mycobacterium sp., C. burnetii, and Legionella pneumophila. Both the Cebula and Guard-Bouldin laboratories have shown that, especially with clonal pathogens, it can be easier, more efficient, and more productive to go from phenotype back to genotype, instead of starting with genomic analyses. 2009, 284 (19): 12585-12592. Instead, a more ideal approach would be to convene a meeting of microbial physiologists and taxonomists charged with the task of agreeing upon an extensive standard list of phenotypes that could be used as a common set to categorize all microbial species. This supports the idea that pathogenic Listeria are using hexose phosphates as a principle C-source for growth in the intracellular environment. 2008 Federation of European Microbiological Societies. Issue tracker/term requests: http://purl.obolibrary.org/obo/omp/devel/omp-term-request. So, for most of the history of life on earth the only forms of life were microorganisms. Escherichia coli and S. aureus change their N-source metabolism in very different ways in response to the C-source they have available. In recent years, these models have been built up in layers, and each layer has been growing in sophistication and accuracy in parallel with a global data set to challenge and validate the models in predicting the content or activities of genes (genomics), proteins (proteomics), metabolites (metabolomics), and ultimately cell phenotypes (phenomics). The microplate wells have, dried down on the bottom, the other nutrients and/or chemicals needed to create the 1920 unique culture conditions for the PM assay set. 10.1038/nbt1346. 10.1093/nar/gkp440. Now there are protocols, using the same set of 1920 PM assays, to test and compare >1000 bacterial species. Both a developers version and official release versions of OMP can be viewed at or downloaded from the development site. The cell suspension has some salts to maintain cell viability, and a tetrazolium redox dye chemistry to measure cell respiration. Here we describe the development of a general Ontology of Microbial Phenotypes (OMP). For purposes of including chemicals found in natural environments, we have also incorporated into this set, tests to measure the sensitivity of bacteria to numerous inorganic chemicals, such as cations (Na+, K+, Fe3+, Cu2+, Co2+, Zn2+, Mn2+, etc.) The measure of the quality of a systems biology model is how well it can reproduce and predict the behaviors of a biological system such as a microbial cell. (Chapter 12). Cell. Uncharacterized genes could be linked to genes that are associated with known phenotypes using a number of bioinformatics approaches including orthology, genomic context (such as operons), co-expression, and protein-protein interactions [5]-[7]. It has ultimately become the foundation of proteomics, the first of the current omics. Just as with other omics and related technologies (DNA sequencing, gene chips, proteomics, and metabolomics), the challenge is to expand the set of assays and make it more accurate, cheaper, easier, and robust, so that scientists can utilize the technology more often and more fully. Single-celled microorganisms were the first forms of life to develop on earth, approximately 3 billion4 billion years ago. With these objectives in mind, my colleagues and I set out to develop a method for global analysis of cell phenotypes, which we called Phenotype MicroArrays (PMs). Genetic analysis of this genome region showed that it was a hot spot for genetic mosaicism. OMP and its associated annotation system have been designed to capture all of these types of phenotypes. Hazelbauer GL, Mesibov RE, Adler J:Escherichia coli mutants defective in chemotaxis toward specific chemicals. These terms are similar to the Gene Ontology (GO) grouping terms such as cell part, GO:0044464, which GO guidelines indicate should not be used for annotation [26],[27]. Terms and Conditions, Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. First is a suspension of cells. cell. Data from one strain are shown in red, the other strain in green, and yellow is the overlapping of the two kinetic curves. (a) An example of the compared C-source metabolic activities of two bacterial strains. Grumbling G, Strelets V: FlyBase: anatomical data, images and queries. Nat Methods. 2011, 12: 32-10.1186/1471-2105-12-32. By combining morphology and Gram-staining, most bacteria can be classified as belonging to one of four groups (Gram-positive cocci, Gram-positive bacilli, Gram-negative cocci, and Gram-negative bacilli). Hannon GJ: RNA interference. The more rapid this metabolic flow, the more quickly purple color is formed. The strain was assayed for C-metabolism using Biolog PM1 MicroPlates. decreased process quality. Butland G, Babu M, Diaz-Mejia JJ, Bohdana F, Phanse S, Gold B, Yang W, Li J, Gagarinova AG, Pogoutse O, Mori H, Wanner BL, Lo H, Wasniewski J, Christopolous C, Ali M, Venn P, Safavi-Naini A, Sourour N, Caron S, Choi JY, Laigle L, Nazarians-Armavil A, Deshpande A, Joe S, Datsenko KA, Yamamoto N, Andrews BJ, Boone C, Ding H: eSGA: Ec coli synthetic genetic array analysis. Ontology of Microbial Phenotypes (OMP) in the context of Basic Formal Ontology (BFO), Phenotypic Quality Ontology (PATO), and Gene Ontology (GO). Emr SD, Hanley-Way S, Silhavy TJ: Suppressor mutations that restore export of a protein with a defective signal sequence. This bacterium is an extreme halophile, preferring to grow in a NaCl concentration of 25%, which causes precipitation problems and makes it challenging to measure cell respiration colorimetrically with dyes. Miller and colleagues (Funchain, 2000) tested mutator strains of E. coli and found that they could use PMs to readily detect phenotypic changes affecting C metabolism in 70% of strains after about 1000 generations of growth. 10.1104/pp.106.092825. Compared with its wild-type parental strain (shown in red), the hyperpathogenic prfA* strain (shown in green) exhibited increased metabolism of hexose phosphates as C-sources (well C1, d-glucose-6-PO4; E3, d-glucose-1-PO4; E4, d-fructose-6-PO4). By contrast, in S. aureus, glucose represses the activity of many N-catabolic pathways but it also activates an entirely different set of active pathways compared with pyruvate. altered cell motility, intersection_of: OMP:0007001 ! A search just for sporulation could return imprecise results. 10.1016/0092-8674(81)90272-5. Coronaviruses are involved in human and vertebrate's diseases. Whereas E. coli exhibits a hierarchical form of crosspathway regulation with fewer N-sources utilized with glucose, as compared with succinate, S. aureus uses an entirely different set of N-sources with glucose, as compared with pyruvate. Classification seeks to describe the diversity of bacterial species by naming and grouping organisms based on similarities. When at the end of the 19thcentury information began to accumulate about the diversity within the bacterial world, scientists started to include the bacteria in phylogenetic schemes to explain how life on earth may have developed. In addition to standard definitions and synonyms, many OMP terms contain a cross product, a special type of logical definition that represents the intersection of two or more terms [29]. Sasser and colleagues (Kunitsky, 2006) developed a biochemical analysis method for membrane lipids, Venter and colleagues (Fraser, 1995) developed a method for sequencing entire genomes and Fodor (1993) developed a method for measuring the mRNA levels in cells. All terms in OMP have genus-differentia definitions, where a term is a subclass of a parent term and is distinguished from other related subclass terms (siblings) by some differentiating characteristic unique to that term (and could be phrased as B is an A that Cs). What was needed was a way to measure hundreds or thousands of phenotypes at a time. This is conceptually possible to achieve using two redox dyes of different redox potentials and colors, the higher redox potential dye for the bacteria and the lower redox potential dye for the mammalian cells. 2005, 201 (12): 1905-1913. Chemicals such as glucose-1-PO4, glucose-6-PO4, and fructose-6-PO4 would not be found in many environments, but would be in high concentrations in the cytoplasm of cells. The preference for glycerol makes sense ecologically as this chemical is an effective osmotic balancer and it is found abundantly in high-salt environments. Microorganisms are very diverse. However, there is a significant heterogeneity in . nov., Cronobacter turicensis sp. We have also deployed a wiki [16] modeled on Gene Ontology Normal Usage Tracking System (GONUTS) [37] for exploring the ontology, and adding usage notes to terms. cell motility, intersection_of: inheres_in GO:0005623 ! Mungall CJ, Gkoutos GV, Smith CL, Haendel MA, Lewis SE, Ashburner M: Integrating phenotype ontologies across multiple species. MC and DS are the primary ontology developers. The rates and extent of color formation in each well of the PM can be monitored and recorded by the omnilog instrument (Bochner, 2003), which is essentially an incubator holding 50 microplates, with a color video camera interfaced to a computer. A final and perhaps most important (in terms of its widespread infectivity in humans) example is the mycobacteria. Cross products are also used in OMP to implement the entity-quality (E-Q) method of phenotypic character description. PubMed Central Nucleic Acids Res. microorganism: An organism that is too small to be seen by the unaided eye, especially a single-celled organism, such as a bacterium. Stud Health Technol Inform. Phenotype refers to an individual's observable traits, such as height, eye color and blood type. It may seem that anything dependent on the genotype is a phenotype, including molecules such as RNA and proteins. Privacy Other laboratories have also performed studies that reinforce this point. Linkage of metabolism is also the basis for detecting N, P, S, and biosynthetic pathways using the same tetrazolium redox assay used to measure C metabolism. An organism's phenotype is all of its observable characteristics which are influenced both by its genotype and by the environment. The classic definition of a phenotype is the physical manifestation of genotype. OMP is a general microbial phenotype ontology applicable to diverse microbes. Certainly, metabolic regulation is different in other bacterial genera. Of these, the publication by Oh and colleagues used PM data most comprehensively. When these cells are important pathogens, the inability to culture them slows the progress in studying them and hinders the entire process of finding curative treatments. More recently (Dalebroux, 2008; Edwards, 2008), this group reported using PM technology to screen a flaAgfp fusion strain (an indicator of differentiation back to the motile transmissive state) under hundreds of culture conditions and discovered that growth arrest and the transition to the motile transmissive form is triggered by carboxylic acids, especially short-chain fatty acids. (May 20, 2013). Open source project development site: http://purl.obolibrary.org/obo/omp/devel/. Correspondence to By inoculating and incubating PM panels with a microorganism that can be cultured in an undefined medium, one can systematically test what stimulates growth, and equally important, what inhibits growth. Why measure respiration instead of growth? The various wells in these panels provide 380 alternative N-sources. Understanding the regulation of genes in the context of the biology of the cell is an even much larger challenge. Single-celled microorganisms were the first forms of life to develop on earth, approximately 3 billion4 billion years ago. DS performs annotations, and supervises student annotators. Growth phenotypes allow microbiologists to describe and thereby differentiate cells. In addition to their use in fleshing out and validating systems biology models, there are many other uses of this global phenotyping technology in basic and applied microbiology research, which are also described. Phenotype is determined by an individual's genotype and expressed genes, random genetic variation, and environmental influences. In cases where the same word refers to multiple concepts, each concept is made into a separate term with a unique identifier and a definition that provides information on the precise meaning, and each term is placed in an appropriate area of the ontology in relation to other terms. Front Microbiol. The preliminary annotations described above are publicly visible via the OMP wiki. 4. The normal temperature of humans and many mammals is 37 C, which is toward or above the upper limit of temperatures tolerated by most fast-growing environmental bacteria and fungi. We need in vivo biological measurements to provide that information, and PM is the most efficient technology for providing the first level of biological data. OMP consists of a controlled vocabulary and structured language where all terms are well-defined representations of microbial phenotypes. Smith B, Ashburner M, Rosse C, Bard J, Bug W, Ceusters W, Goldberg LJ, Eilbeck K, Ireland A, Mungall CJ, Leontis N, Rocca-Serra P, Ruttenberg A, Sansone SA, Scheuermann RH, Shah N, Whetzel PL, Lewis S: The OBO Foundry: coordinated evolution of ontologies to support biomedical data integration. 10.1074/jbc.X800017200. Then what is needed is a practical technology to analyze all microbial species and provide a database of these standard phenotypes. In Diffen.com. The variable level of purple color indicates that the cells are metabolically active and respiring in some wells but not others. Nat Methods. Article Cite this article. For most C-sources, metabolism was more rapid at the warmer temperature. Therefore the intracellular environment presumably has most sugars in the form of sugar phosphates. Since then, we have periodically refined the structure, as needed based on feedback from the community and project annotators. decreased cell motility), OMP follows the model of PATO, which defines process quality (PATO:0001236) as a quality which inheres in a process.. Genome Biol. sakazakii, comb. In addition to their use in fleshing out and validating systems biology models, there are many other uses of this global phenotyping technology in basic and applied microbiology research, which are also described. Nevertheless, experiments could be performed where E. coli was cultured under different growth conditions, and changes could be clearly detected in the protein composition of the bacterium. https://doi.org/10.1186/s12866-014-0294-3, http://purl.obolibrary.org/obo/omp/devel/, http://purl.obolibrary.org/obo/omp/devel/omp-term-request, http://purl.obolibrary.org/obo/omp/omp.obo, http://purl.obolibrary.org/obo/omp/omp-simple.obo, http://amigo.geneontology.org/amigo/term/GO:0044464, http://oboedit.org/docs/html/Introduction_to_Cross_Products.htm, http://creativecommons.org/licenses/by/4.0, http://creativecommons.org/publicdomain/zero/1.0/. A term tracker [35] is used to manage term requests, which are researched and added into the ontology. There are certainly gene families in cells and evidence of genes that are either partially or fully redundant. We have included umbrella terms to group independent and dependent phenotype terms that refer to the same biological concepts (Figure3). Systems biologists would typically view gene function as a descriptive unit of genome annotation, and ideally such annotation would fully describe all functions of all genes. Nucleic Acids Res. Using PM technology to determine nutrients that stimulated respiration, they have ultimately succeeded in optimizing axenic culture conditions so that it can be maintained in a viable and metabolically active state outside of its host cell for >24 h (Bochner, 2008). There are a number of laboratories using PM technology in novel ways to delve into various aspects of bacterial pathogenicity and the related issue of epidemiology. A person's phenotype is determined by both their genomic makeup (genotype) and environmental factors. Operating system(s): Platform independent. However, in 2003 (Bochner, 2003), I proposed the need for a second map, a phenotypic map, that would also be annotated in concert with genomic maps. Annotations can be viewed on the OMP wiki. Part of For example, the OMP term motility phenotype is equivalent to the intersection of the OMP root term microbial phenotype (OMP:0000000) and the GO biological process term cell motility (GO:0048870) using the OBO Relations Ontology [30] relationship inheres_in (RO:0000052). 10.1073/pnas.64.4.1300. Assays were performed in Biolog PM3 MicroPlates, which contain a negative control well (well A1) and 95 different potential N-sources. We recommend that they not be used directly in annotations as there will usually be a more specific child term available. nov., Cronobacter muytjensii sp. Second, it allows the measurement of more cellular pathways. In contrast, the genotype is the chemical makeup of DNA that causes a particular phenotype. Wenyuan Shi and colleagues (Chavira, 2007) used PMs to screen for and find culture conditions that altered the morphology of fruiting bodies in Myxococcus xanthus. Terms for both independent and dependent phenotypes are essential to represent the richness of genetics and genetic interactions (for examples, see [18]-[22]). Genome Biol. Differences were reported (Bochner, 2008) in both their C metabolism (for d-lactose, cellobiose, gentiobiose, amygdalin, salicin, l-asparagine, d-alanine, l-alanyl-glycine, fumaric acid, and bromo-succinic acid) and their N metabolism (l-glutamine). PMs have been conceived of and designed as a technology to survey phenotypes of a cell from a physiological perspective. Currently, OMP is being used to annotate phenotypes associated with Escherichia coli genes and strains. CAS Most cells take up sugars and in doing so the sugars are usually phosphorylated as part of the transport process. Kluyver at the Technological University at Delft, the Netherlands (den Dooren de Jong, 1926). Biologists understand that the cell is a system, but we are just at the early stages of describing cells as such. They include bacteria, fungi, algae, and protozoa; microscopic plants, and animals. Phenotypic heterogeneity is a potentially important component of biological diversity; it arises at the level of individual microbial cells and provides groups of microorganisms with added. Punta M, Ofran Y: The rough guide to in silico function prediction, or how to use sequence and structure information to predict protein function. Nucleic Acids Res. 3). These are based on a specified genus and a collection of differentiae. BMC Microbiology Just as all bacteria can be described with a powerful common framework of their 16S rRNA gene or genomic DNA sequences, it would also be highly desirable and productive to describe all bacteria by their phenotypes, which reflects their physiology. GASP is defined by the ability of cells aged in long . This uncertainty was due to the lack of distinct structures in most bacteria, as well as lateral gene transfer between unrelated species. 10.1016/j.cell.2010.11.052. Accessibility StatementFor more information contact us atinfo@libretexts.org. One of the most interesting and productive series of works has come from studies of the highly clonal pathogen, S. enterica serovar Enteritidis. Phenotypic data are routinely used to elucidate gene function in organisms amenable to genetic manipulation. Terms have logical definitions that can facilitate computational searching of phenotypes and their associated genes. As challenging as this task is when considering cellular life . Ontology of Microbial Phenotypes issue tracker. Xiang-He Lei in our laboratory tested a strain of Halobacterium salinarum provided by Schmid and Baliga (Schmid, 2007). In addition to their use in fleshing out and validating systems biology models, there are many other uses of this global phenotyping technology in basic and applied microbiology research, which are also described. As described in this review, phenotypic information is a very useful form of information that complements the current information obtained from global biochemical and molecular analysis. So far we have associated phenotypes to observations made in 275 papers. Conversely, when a poor C-source is provided, such as succinate, the transport and metabolism of virtually all of E. coli's numerous N-sources is turned on. Traditionally, phenotypes and genotypes were linked together by studying a mutant phenotype of interest followed by genetic mapping and characterization to identify the genetic change that is responsible for the phenotype, a process known as forward genetics. A) an independent annotation showing chemotaxis in the parent strain based on a swimming assay in semisolid medium. PM technology has numerous uses in industrial microbiology, particularly in efficiently optimizing the yields and improving the reproducibility of fermentation processes. Phenotype - The observable characteristics of an organism determined by its gene expression in a given environment. The N-, P-, and S-source assays are not working for all these species, but the C-source and chemical sensitivity assays are. Different strains of this pathogen share 99.99% genomic identity; yet, surprisingly, they vary greatly in their pathogenic properties. Day-Richter J, Harris MA, Haendel M, Working Group Gene Ontology OBO-Edit, Lewis S: OBO-Editan ontology editor for biologists. In Biology. Introduction.

Schoolnik and colleagues (Keymer, 2007) have used PM technology to help understand how environmental and ecological factors influence the genomic and phenotypic diversity of strains of the pathogen V. cholerae. They compared the Pasteur and Russian strains of M. bovis BCG, which have a long and important history in medical microbiology as general immunological adjuvants, and as attenuated vaccine strains for tuberculosis. Therefore, the phenotype is the total characteristics displayed by an organism that results from the expression of the genes of an organism as . This work (Zhou, 2003) took advantage of a method recently introduced for making precise deletions of the entire gene (Datsenko & Wanner, 2000). With PM technology now available for bacterial, fungal, and animal cells, these advantages can be applied across a wide range of bioprocesses. Work is now in progress to make double-gene knockouts to provide additional phenotypic information for testing systems biology metabolic models (Bochner, 2008). If a strain of E. coli were observed to move, it would have the independent phenotype presence of cell motility. Evolutionary forces will drive bacteria to grow in as many environmental niches as possible. These large numbers are indicative of the diversity of ecological niches on our planet. Some of these are universal necessary for all forms of life. License: Creative Commons Attribution-ShareAlike 3.0 (CC BY-SA 3.0 US), Any restrictions to use by non-academics: None. There are some basic differences between Bacteria, Archaea, and Eukaryotes in cell morphology and structure which aid in phenotypic classification and identification. Many microbial cells remain unculturable or very difficult and slow to culture. Lei also made the surprising and interesting observation that inorganic phosphate not only is not a preferred source of P but it is actually toxic to Halobacterium at low millimolar levels. These differences in metabolic capabilities are likely to contribute to colonization capabilities in various environments. However, information about the enzymes and pathways present in cells is much less comprehensive than generally acknowledged.
