Phylogenetic Algebraic Geometry [PDF]

open access: yes, 2004
Phylogenetic algebraic geometry is concerned with certain complex projective algebraic varieties derived from finite trees. Real positive points on these varieties represent probabilistic models of evolution.

On the number of vertices of each rank in phylogenetic trees and their generalizations

open access: yes, 2016
We find surprisingly simple formulas for the limiting probability that the rank of a randomly selected vertex in a randomly selected phylogenetic tree or generalized phylogenetic tree is a given integer.Comment: 7 pages, 1 ...

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

open access: yesFEBS 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 ...

Characterization of Chloroplast Genomes From Two Salvia Medicinal Plants and Gene Transfer Among Their Mitochondrial and Chloroplast Genomes

open access: yesFrontiers in Genetics, 2020
Salvia species have been widely used as medicinal plants and have played an important role in the treatment and recovery of individuals with COVID-19. In this study, we reported two newly identified whole chloroplast genome sequences of Salvia medicinal ...

Relapsing–Remitting Multiple Sclerosis Is Associated With a Dysbiotic Oral Microbiome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by inflammation, demyelination, and neurological impairment. While the gut microbiota's role in MS is extensively studied, the association between the oral microbiota and MS remains underexplored, particularly in North American cohorts.

The complete chloroplast genome sequence of Abies beshanzuensis, a highly endangered fir species from south China

open access: yesMitochondrial DNA. Part B. Resources, 2018
Abies beshanzuensis is critically endangered and endemic to Zhengjiang province of China, with only three surviving individuals. In present study, we reported the complete chloroplast (cp) genome of Abies beshanzuensis.

Molecular Characterization of Haemaphysalis Species and a Molecular Genetic Key for the Identification of Haemaphysalis of North America

open access: yesFrontiers in Veterinary Science, 2020
Haemaphysalis longicornis (Acari: Ixodidae), the Asian longhorned tick, is native to East Asia, but has become established in Australia and New Zealand, and more recently in the United States.

pH‐Tunable Material Properties of Glycine‐Rich Condensates from Tick Bioadhesive

open access: yesAdvanced Functional Materials, EarlyView.
This work studies the influence of pH on the phase separation behavior of a disordered glycine‐rich protein found in tick bioadhesive. The results show profound impact on the propensity of coacervation, condensate microstructure and viscosity, amphiphilicity of the peptides, and effective encapsulation of therapeutic molecules.

The complete mitochondrial genome and phylogenetic analysis of Epitonium scalare (Gastropoda, Epitoniidae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The complete mitochondrial genome of the Epitonium scalare has been determined in this study. The complete genome (mtDNA) is 15,140 base pairs (bp) in length and contained of 13 protein-coding genes, two rRNA genes, and 22 tRNA genes.
