Multipolar Consensus for Phylogenetic Trees [PDF]
Systematic Biology, 2006 Collections of phylogenetic trees are usually summarized using consensus methods. These methods build a single tree, supposed to be representative of the collection. However, in the case of heterogeneous collections of trees, the resulting consensus may be poorly resolved (strict consensus, majority-rule consensus, ...), or may perform arbitrary ...

Protein O‐glycosylation in the Bacteroidota phylum
FEBS Open Bio, EarlyView.Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

On Tree-Based Phylogenetic Networks [PDF]
Journal of Computational Biology, 2016 A large class of phylogenetic networks can be obtained from trees by the addition of horizontal edges between the tree edges. These networks are called tree based networks. Reticulation-visible networks and child-sibling networks are all tree based. In this work, we present a simply necessary and sufficient condition for tree-based networks and prove ...

Production of antibacterial compounds by a Steely hybrid polyketide synthase in Dictyostelium
FEBS Open Bio, EarlyView.By selecting appropriate production species under optimised culture conditions, new chlorinated dibenzofuran compounds, which previously could not be analysed in sufficient quantities, were identified from cellular slime mould fruiting bodies. The strong antibacterial activity exhibited by these compounds suggests a link to the ecological function of ...

Aegilops tauschii Coss. molecular phylogeny in comparison with proteins electrophoretic polymorphism
Acta Biologica Sibirica, 2023 In the case of Aegilops tauschii the comparison of intraspecies molecular phylogeny based on DNA sequences of nuclear gene Got2 with electrophoretic polymorphism of allozymes and hystone H1 proteins is actually a comparison of the one detailed ...

FEBS Open Bio, EarlyView.Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Phylophenetic properties of metabolic pathway topologies as revealed by global analysis
BMC Bioinformatics, 2006 Background As phenotypic features derived from heritable characters, the topologies of metabolic pathways contain both phylogenetic and phenetic components.

A Universal Phylogenetic Tree [PDF]
The American Biology Teacher, 2001 THIS paper presents a universal phylogenetic tree (Figure 1) suitable for use in high school and college biology classrooms. It is made possible by whole genome sequencing techniques that have been available since the mid 1990s. While it is likely that many of the details of the tree will change in the years ahead as more genome sequences become ...

Locating a tree in a phylogenetic network [PDF]
Information Processing Letters, 2010 Phylogenetic trees and networks are leaf-labelled graphs that are used to describe evolutionary histories of species. The Tree Containment problem asks whether a given phylogenetic tree is embedded in a given phylogenetic network. Given a phylogenetic network and a cluster of species, the Cluster Containment problem asks whether the given cluster is a ...
