Troubleshooting Molecular Phylogenetic Analyses
Annual Review of Ecology and Systematics, 2002▪ Abstract The number, size, and scope of phylogenetic analyses using molecular data has increased steadily in recent years. This has simultaneously led to a dramatic improvement in our understanding of phylogenetic relationships and a better appreciation for an array of methodological problems that continue to hinder progress in phylogenetic studies ...

Phylogenetic analyses of mode of larval development
Seminars in Cell & Developmental Biology, 2000Phylogenies based on morphological or molecular characters have been used to provide an evolutionary context for analysis of larval evolution. Studies of gastropods, bivalves, tunicates, sea stars, sea urchins, and polychaetes have revealed massive parallel evolution of similar larval forms.

Molecular-phylogenetic analyses of human gastrointestinal microbiota
Current Opinion in Gastroenterology, 2001Molecular-phylogenetic methods have revolutionized the analysis of complex microbial communities. Polymerase chain reaction amplification and phylogenetic analysis of small-subunit ribosomal RNA gene sequences allow microbes to be identified objectively, even in the absence of cultivation.

Signal, Noise, and Reliability in Molecular Phylogenetic Analyses
Journal of Heredity, 1992DNA sequences and other molecular data compared among organisms may contain phylogenetic signal, or they may be randomized with respect to phylogenetic history. Some method is needed to distinguish phylogenetic signal from random noise to avoid analysis of data that have been randomized with respect to the historical relationships of the taxa being ...

Sequence, phylogenetic and variant analyses of antithrombin III
Biochemical and Biophysical Research Communications, 2013Antithrombin III (ATIII) performs a critical anticoagulant function by precluding the activation of blood clotting proteinases, aided by its two cofactors, heparin and heparan sulfate. Though several studies have been carried out on physiological, biochemical and structural perspectives on ATIII, so far there are limited studies on the molecular ...

Phylogenetic Analyses of Parasites in the New Millennium
2006Phylogenetic analysis has changed greatly in the last decade, and the most important themes in that change are reviewed here. Sequence data have become the most common source of phylogenetic information. This means that explicit models for evolutionary processes have been developed in a likelihood context, which allow more realistic data analyses ...

Phylogenetic Analyses of Chemokine Receptors from Sequence Retrieval to Phylogenetic Trees
2020Phylogenetic trees are an essential requisite for comparative biology studies where hypotheses regarding the evolution of genes can be investigated. Trees provide visual and statistical guides to characterize the degree of relatedness among biological entities from genes to species.

Phylogenetic and Structural Analyses of Vesicular Glutamate Transporters
Molecular NeurobiologyVesicular glutamate transporters are members of the solute carrier 17 (SLC17) family, and mammals express three closely related isoforms: vGluT1-3. While vGluT genes have been identified across various species in the Animalia kingdom, the evolutionary relationships and the natural history of vGluT members remain poorly understood.
