In a methodological advance, 2R ohnologs were identified using detailed phylogenetic trees on the basis of a tree-merging algorithm implemented in the TreeFam database.
Possible applications of MGcV include: annotation refinement, function prediction on basis of a (phylogenetic) tree and conserved gene context, the sequence-based reconstruction of gene regulatory networks, and microarray/RNA-seq data analysis.
In addition, the Woodland Trust , Forestry Commissionand the Earth Trust are hoping to identify resistant trees to form the basis of a nationwide tree-breeding programme.
On the basis of a decision-tree prediction model using four prehospital variables (shockable initial rhythm, age, witnessed arrest, and witnessed by EMS personnel), OHCA patients can be readily stratified into the four groups (good, moderately good, poor, and absolutely poor) that help predict both survival at 1 month and survival with favorable neurologic outcome at 1 month.
Rabies is estimated to cause >60,000 human deaths worldwide annually on the basis of a probability decision-tree approach; primarily resulting from dog bites, the disease is of public health concern in most countries in Asia and Africa (1 ).
On the basis of tree topology of a maximum-likelihood phylogenetic tree, the sequence does not cluster with rodent-associated hantaviruses but groups with those found in shrews and moles.
On the basis of a reconciled species-domain tree including both SRLKs and SRLCKs, gene duplication/loss and fusion events in SRLK evolution were inferred and dated by integrating the maximum parsimony ancestral architecture inference algorithm [ 25, 26] into the widely applied gene duplication/loss model [ 32].
On the basis of phylogenetic tree analysis, the relationships among cyclins A, B, D and E in different animal taxa were investigated [ 20].
This result is reminiscent of the result of Atteson (1999), who proved that the consistency of neighbor joining is robust to a certain degree of noise in the distance matrix, in that the method can still construct a correct tree when distances obtained on the basis of that tree are slightly perturbed.
Phylogenetic ortholog identification methods that require gene tree topologies to agree with trusted species phylogenies may have limited accuracy when sequence fragments are included in an analysis or when the domain used as the basis of evolutionary tree construction is short, reducing the phylogenetic signal.
On the basis of the obtained tree, a haplotype network including geographic information and frequency of haplotypes was built.
