(1990) used ribosomal RNA sequences to generate a "universal phylogenetic tree" that clearly grouped living organisms into three clusters, which he used to propose his three-domain system (Domains Archaea, Bacteria, Eukarya).
We have redrawn a phylogenetic tree using only this 196-nucleotide segment after omitting the primer regions from the sequence used.
In this study we have reconstructed the phylogenetic tree of a select group of basidiomycete fungi using nucleotide sequences of the ITS region of the rDNA suite of genes and have compared this to trees generated from RFLP analysis using general fungal and basidiomycete-specific primers to see if the latter procedures can correctly identify multiple isolates of select wood decay fungi.
These four recently integrated hamster B2 elements were analyzed to assess their usefulness as a phylogenetic tool particularly in regards to the surprising restructuring of the hamster phylogenetic tree (Neumann et al.
Genome size was traced along the individual branches of the phylogenetic tree. Ancestral character states were reconstructed using algorithms for squared-change (Maddison, 1991) and Wagner parsimony (Swofford and Maddison, 1987) in MACCLADE V.
This makes for short, confidence-eroding branches in otherwise well-resolved phylogenetic trees. The classic examples are the Cambrian explosion of animal phyla and the K/T explosion of mammal orders.

The phylogenetic tree showed a close evolutionary relationship of Sindh ibex with goat and sheep (Fig.
The Neighbor joining phylogenetic tree was constructed by using maximum likelihood method implemented in a desktop application named as MEGA 6.
The data obtained as a result of multiple sequence alignment, was represented in the form of rooted UPGMA (unweighted pair group method of arithmetic mean) phylogenetic tree. The phylogenetic tree was interpreted in order to analyze the genetic evolutionary lineage.
[7] reconstructs phylogenetic tree from inferred SNV frequencies based on two assumptions: (i) no mutation occurs twice in the course of cancer evolution and (ii) no mutation is ever lost.
Under the standardized culture condition for fungus, these two strains were identified by the traditional morphology and the method of phylogenetic tree construction after cloning the 18S rDNA-ITS segment, respectively.
