Branching Order Of Bacterial Phyla (Gupta, 2001)
There are several models of the Branching order of bacterial phyla, one of these was proposed in 2001 by Gupta based on conserved indels or protein, termed "protein signatures", an alternative approach to molecular phylogeny. Some problematic exceptions and conflicts are present to these conserved indels, however, they are in agreement with several groupings of classes and phyla. One feature of the cladogram obtained with this method is the clustering of cell wall morphology (with some exceptions) from monoderms to transitional diderms to traditional diderms. In the cladogram below, yellow=pseudopeptidoglycan monoderms (Gram variable), red=thick peptidoglycan monoderms (Gram positive), blue=thin peptidoglycan diderms (Gram negative), green=atypical, see note in parentheses).

Branching Order Of Bacterial Phyla (Woese, 1987)
There are several models of the Branching order of bacterial phyla, one of these was proposed in 1987 paper by Carl Woese. The branching order proposed by Carl Woese was based on molecular phylogeny, which was considered revolutionary as all preceding models were based on discussions of morphology. (''v.'' Monera). Several models have been proposed since and no consensus is reached at present as to the branching order of the major bacterial lineages. The gene used was the 16S ribosomal DNA. Tree The names have been changed to reflect more current nomenclature used by molecular phylogenists. Note on names Despite the impact of the paper on bacterial classification, it was not a proposal for change of taxonomy. Consequently, many clades were given official names. Only subsequently, this occurred: for example, the "purple bacteria and relatives" were renamed Proteobacteria. Discussion In 1987, Carl Woese, regarded as the forerunner of the molecular phylogeny revolution, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Branching Order Of Bacterial Phyla (Rappe And Giovanoni, 2003)
There are several models of the Branching order of bacterial phyla, the most cited of these was proposed in 1987 paper by Carl Woese Carl Richard Woese (; July 15, 1928 – December 30, 2012) was an American microbiologist and biophysicist. Woese is famous for defining the Archaea (a new domain of life) in 1977 through a pioneering phylogenetic taxonomy of 16S ribosomal RNA, .... This cladogram was later expanded by Rappé and Giovanoni in 2003 to include newly discovered phyla. Clear names are added in parentheses, see ''list of bacterial phyla''.

Branching Order Of Bacterial Phyla After ARB Silva Living Tree
The All-Species Living Tree' Project is a collaboration between various academic groups/institutes, such as ARB, SILVA rRNA database project, and LPSN, with the aim of assembling a database of 16S rRNA sequences of all validly published species of ''Bacteria'' and ''Archaea''. At one stage, 23S sequences were also collected, but this has since stopped. Currently there are over 10,950 species in the aligned dataset and several more are being added either as new species are discovered or species that are not represented in the database are sequenced. Initially the latter group consisted of 7% of species. Similar (and more recent) projects include the Genomic Encyclopedia of Bacteria and Archaea (GEBA), which focused on whole genome sequencing of bacteria and archaea. Tree The tree was created by maximum likelihood analysis without bootstrap: consequently accuracy is traded off for size and many phylum level clades are not correctly resolved (such as the Firmicutes).

Branching Order Of Bacterial Phyla (Cavalier-Smith, 2002)
There are several models of the Branching order of bacterial phyla, one of these was proposed in 2002 and 2004 by Thomas Cavalier-Smith. In this frame of work, the branching order of the major lineage of bacteria are determined based on some morphological characters, such as cell wall structure, and not based on the molecular evidence (molecular phylogeny). Whereas modern molecular studies point towards the root of the tree of life being between a monophyletic Bacteria and Archaea+Eukarya (Neomura), in the Cavalier-Smith theory, the last common ancestor (cenansestor) was a Gram-negative diderm bacterium with peptidoglycan, while Archaea and Eukaryotes stem from Actinobacteria.

Bacteriology
Bacteriology is the branch and specialty of biology that studies the morphology, ecology, genetics and biochemistry of bacteria as well as many other aspects related to them. This subdivision of microbiology involves the identification, classification, and characterization of bacterial species. Because of the similarity of thinking and working with microorganisms other than bacteria, such as protozoa, fungi, and viruses, there has been a tendency for the field of bacteriology to extend as microbiology. The terms were formerly often used interchangeably. However, bacteriology can be classified as a distinct science. Overview Definition Bacteriology is the study of bacteria and their relation to medicine. Bacteriology evolved from physicians needing to apply the germ theory to address the concerns relating to disease spreading in hospitals the 19th century. Identification and characterizing of bacteria being associated to diseases led to advances in pathogenic bacteriology. K ...
