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 Proton-Translocating Transhydrogenases
Microbial & Comparative Genomics, 1999The proton-translocating nicotinamide nucleotide transhydrogenases (TH) provide a simple model for understanding chemically coupled transmembrane proton translocation. To further our understanding of TH structure-function relationships, we have identified all sequenced homologous of these vectorial enzymes and have conducted sequence comparison studies.

Homologies in phylogenetic analyses—concept and tests
Theory in Biosciences, 2005Analyzing morphological characters in a phylogenetic context comprises two steps, character analysis and cladistic analysis, which are equivalent to two independent tests for hypotheses on homology. The concept of homology concerns comparable parts of the same or different organisms if their correspondences are the consequence of the same genetic or ...

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.

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 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.
