Phylogenetic analyses of Chaetopteridae (Annelida)
Zoologica Scripta, 2017 Phylogenetic relationships within Chaetopteridae were assessed using parsimony cladistic analysis of 43 external morphological characters and molecular phylogenetic analysis of three genes: mitochondrial cytochrome oxidase subunit I DNA (COI) and nuclear 28S and 18S ribosomal DNA. The group currently comprises four accepted genera: Chaetopterus Cuvier,

Bootstrap and Rogue Identification Tests for Phylogenetic Analyses [PDF]
Molecular Biology and Evolution, 2018 Most phylogenetic tree-generating programs produce a fully dichotomous phylogenetic tree. However, as different markers may produce distinct topologies for the same set of organisms, topological tests are used to estimate the statistical reliability of the clades.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

The complete mitochondrial genome of the nematode-trapping fungus Dactylellina haptotyla
Mitochondrial DNA. Part B. Resources, 2018 The complete mitochondrial genome of Dactylellina haptotyla was studied in this study. This mitogenome is a closed circular molecule of 146,101 bp in length with a GC content of 22.92%, including 14 protein-coding genes, 26 transfer RNA genes, 2 ...

Phylogenetic trait‐based analyses of ecological networks [PDF]
Ecology, 2013 Ecological networks of two interacting guilds of species, such as flowering plants and pollinators, are common in nature, and studying their structure can yield insights into their resilience to environmental disturbances. Here we develop analytical methods for exploring the strengths of interactions within bipartite networks consisting of two guilds ...

Molecular Oncology, EarlyView.EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.
