A probabilistic model for gene content evolution with duplication, loss, and horizontal transfer

, 2005
We introduce a Markov model for the evolution of a gene family along a phylogeny. The model includes parameters for the rates of horizontal gene transfer, gene duplication, and gene loss, in addition to branch lengths in the phylogeny. The likelihood for

VICTOR: genome-based phylogeny and classification of prokaryotic viruses

bioRxiv, 2017
Bacterial and archaeal viruses (“phages”) play an enormous role in global life cycles and have recently regained importance as therapeutic agents to fight serious infections by multi-resistant bacterial strains.

Biodiversity of Nematodes from Coral Reef Sediments in the South China Sea Based on eDNA Metabarcoding

Diversity
Coral reef ecosystems in the South China Sea are one of the globally important marine biodiversity hotspots. However, there are few studies on nematode biodiversity in coral reef sediments.

Ciliate Environmental Diversity Can Be Underestimated by the V4 Region of SSU rDNA: Insights from Species Delimitation and Multilocus Phylogeny of Pseudokeronopsis (Protist, Ciliophora)

Microorganisms, 2019
Metabarcoding and high-throughput sequencing methods have greatly improved our understanding of protist diversity. Although the V4 region of small subunit ribosomal DNA (SSU-V4 rDNA) is the most widely used marker in DNA metabarcoding of eukaryotic ...

A phylogeny and revised classification of Squamata, including 4161 species of lizards and snakes

BMC Evolutionary Biology, 2013
BackgroundThe extant squamates (>9400 known species of lizards and snakes) are one of the most diverse and conspicuous radiations of terrestrial vertebrates, but no studies have attempted to reconstruct a phylogeny for the group with large-scale taxon ...

Genomic dissection of the 1994 Cronobacter sakazakii outbreak in a French neonatal intensive care unit [PDF]

, 2015
Background: Cronobacter sakazakii is a member of the genus Cronobacter that has frequently been isolated from powdered infant formula (PIF) and linked with rare but fatal neonatal infections such as meningitis and necrotising enterocolitis.

Anaerococcus marasmi sp. nov., a new bacterium isolated from human gut microbiota

New Microbes and New Infections, 2020
Anaerococcus marasmi sp. nov. strain Marseille-P3557T is a new species isolated from a stool of a Nigerian child with marasmus. The genome of Marseille-P3557T was 2 130 060 bp long (35.4% G + C content).

Phylogeny of Prokaryotes and Chloroplasts Revealed by a Simple Composition Approach on All Protein Sequences from Complete Genomes Without Sequence Alignment [PDF]

, 2005
The complete genomes of living organisms have provided much information on their phylogenetic relationships. Similarly, the complete genomes of chloroplasts have helped to resolve the evolution of this organelle in photosynthetic eukaryotes.
