Biochemical and phylogenetic networks-II: X-trees and phylogenetic trees [PDF]
Journal of Mathematical Chemistry, 2021 The present study, which is a continuation of the previous paper, augments a recent work on the use of phylogenetic networks. We develop techniques to characterize the topology of various X-trees and binary trees of biological and phylogenetic interests. We have obtained the results for various k-level X-trees and phylogenetic networks with variants of

Journal of Software for Algebra and Geometry, 2021 We introduce the package PhylogeneticTrees for Macaulay2 which allows users to compute phylogenetic invariants for group-based tree models. We provide some background information on phylogenetic algebraic geometry and show how the package PhylogeneticTrees can be used to calculate a generating set for a phylogenetic ideal as well as a lower bound for ...

Species divergence and phylogenetic variation of ecophysiological traits in lianas and trees. [PDF]
PLoS ONE, 2014 The climbing habit is an evolutionary key innovation in plants because it is associated with enhanced clade diversification. We tested whether patterns of species divergence and variation of three ecophysiological traits that are fundamental for plant ...

Construction of a phylogenetic tree of photosynthetic prokaryotes based on average similarities of whole genome sequences. [PDF]
PLoS ONE, 2013 Phylogenetic trees have been constructed for a wide range of organisms using gene sequence information, especially through the identification of orthologous genes that have been vertically inherited.

Algorithms for Molecular Biology, 2023 Objective In mathematical phylogenetics, a labeled rooted binary tree topology can possess any of a number of labeled histories, each of which represents a possible temporal ordering of its coalescences.

DendroSSR: SSRs and sequence alignment as tools for building phylogeny trees
Brazilian Journal of Biology, 2023 This study introduces a new method to construct phylogenetic trees by combining both of the Simple Sequence Repeats (SSRs) and sequence alignments.

Folding and unfolding phylogenetic trees and networks [PDF]
, 2015 Phylogenetic networks are rooted, labelled directed acyclic graphs which are commonly used to represent reticulate evolution. There is a close relationship between phylogenetic networks and multi-labelled trees (MUL-trees).

Visualizing phylogenetic tree landscapes [PDF]
BMC Bioinformatics, 2017 Genomic-scale sequence alignments are increasingly used to infer phylogenies in order to better understand the processes and patterns of evolution. Different partitions within these new alignments (e.g., genes, codon positions, and structural features) often favor hundreds if not thousands of competing phylogenies.

PhyloFinder: An intelligent search engine for phylogenetic tree databases
BMC Evolutionary Biology, 2008 Background Bioinformatic tools are needed to store and access the rapidly growing phylogenetic data. These tools should enable users to identify existing phylogenetic trees containing a specified taxon or set of taxa and to compare a specified ...

A vectorial tree distance measure
Scientific Reports, 2022 A vectorial distance measure for trees is presented. Given two trees, we define a Tree-Alignment (T-Alignment). We T-align the trees from their centers outwards, starting from the root-branches, to make the next level as similar as possible.
