Prokaryotic phylogenies inferred from protein structural domains.
The determination of the phylogenetic relationships among microorganisms has long relied primarily on gene sequence information. Given that prokaryotic organisms often lack morphological characteristics amenable to phylogenetic analysis, prokaryotic phylogenies, in particular, are often based on sequence data. In this work, we explore a new source of phylogenetic information, the distribution o...
متن کاملProkaryotic Phylogenies Inferred from Whole-Genome Sequence and Annotation Data
Phylogenetic trees are used to represent the evolutionary relationship among various groups of species. In this paper, a novel method for inferring prokaryotic phylogenies using multiple genomic information is proposed. The method is called CGCPhy and based on the distance matrix of orthologous gene clusters between whole-genome pairs. CGCPhy comprises four main steps. First, orthologous genes ...
متن کاملHow should species phylogenies be inferred from sequence data?
levels as follows: (1) Separate gene trees are inferred from each linkage partition, and (2) the species phylogeny is then inferred from the set of gene trees. A method (Maddison, 1997; Page and Charleston, 1997a, 1997b; Slowinski et al., 1997) termed gene tree parsimony by Slowinski et al. (1997) is the appropriate method for implementing the second step. Gene tree parsimony operates by findin...
متن کاملPositive correlation between diversification rates and phenotypic evolvability can mimic punctuated equilibrium on molecular phylogenies.
The hypothesis of punctuated equilibrium proposes that most phenotypic evolution occurs in rapid bursts associated with speciation events. Several methods have been developed that can infer punctuated equilibrium from molecular phylogenies in the absence of paleontological data. These methods essentially test whether the variance in phenotypes among extant species is better explained by evoluti...
