Phylogeny of Gammaproteobacteria [PDF]

Journal of Bacteriology, 2010
ABSTRACT The phylogeny of the large bacterial class Gammaproteobacteria has been difficult to resolve. Here we apply a telescoping multiprotein approach to the problem for 104 diverse gammaproteobacterial genomes, based on a set of 356 protein families for the whole class and even larger sets for each of ...

Phylogeny numbers

Discrete Applied Mathematics, 1998
For an acyclic digraph \(D=(V,A)\), the phylogeny graph \(P(D)=(V,E)\) has, for vertices \(x\neq y\), an (undirected) edge \(xy\in E\) iff (1) \((x,y)\in A\) or (2) \((y,x)\in A\) or (3) (both) \((x,a),(y,a)\in A\) for some vertex \(a\in V\); it is a supergraph of the competition graph of \(D\) for which only condition (3) is required.

The mitochondrial genome of Lamellomphalus manusensis Zhang & Zhang, 2017 (Gastropoda: Neomphalida) from deep-sea hydrothermal vent

Mitochondrial DNA. Part B. Resources, 2022
We report the nearly complete mitochondrial genome sequence of Lamellomphalus manusensis Zhang and Zhang , a deep-sea snail inhabiting hydrothermal vent. The mitogenome is 15,990 bp in length, has a base composition of A (35.7%), T (33.5%), C (15.4%) and

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 ...

Usurpativirus massiliensis, a new giant virus related to clandestinovirus

Virology Journal
Giant virus discovery in 2003 revolutionized the virus paradigm. In 2015, we introduced a new host, Vermamoeba vermiformis, that led to the discovery of Faustovirus, Orpheovirus and two giant viruses (Clandestinovirus and a faustovirus) having distinct ...

Are Fertility Preservation Procedures Before Gonadotoxic Therapy and Hematopoietic Stem Cell Transplantation Feasible and Safe in Very Young Children? A Retrospective Cohort Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Fertility preservation (FP) is increasingly integrated into the care of pediatric patients exposed to gonadotoxic therapy or conditioning for hematopoietic stem cell transplantation (HSCT), yet perioperative data in infants and toddlers remain scarce.
