An Update of Orthopoxvirus Molecular Evolution

open access: yesViruses, 2022
Although variola virus (VARV) has been eradicated through widespread vaccination, other orthopoxviruses pathogenic for humans circulate in nature. Recently, new orthopoxviruses, including some able to infect humans, have been found and their complete ...

The molecular evolution of spermatogenesis across mammals

open access: yesbioRxiv, 2021
The testis produces gametes through spermatogenesis and evolves rapidly at both the morphological and molecular level in mammals^ 1 – 6 , probably owing to the evolutionary pressure on males to be reproductively successful^ 7 .

THE MOLECULAR EVOLUTION OF ACTIN [PDF]

open access: yesGenetics, 1986
ABSTRACT We have investigated the molecular evolution of plant and nonplant actin genes comparing nucleotide and amino acid sequences of 20 actin genes. Nucleotide changes resulting in amino acid substitutions (replacement substitutions) ranged from 3-7% for all pairwise comparisons of animal actin genes with the following exceptions ...

Galaxy chemical evolution models: The role of molecular gas formation [PDF]

open access: yes, 2017
In our classical grid of multiphase chemical evolution models, star formation in the disc occurs in two steps: first, molecular gas forms, and then stars are created by cloud-cloud collisions or interactions of massive stars with the surrounding ...

Molecular Evolution of Aphthoviruses

open access: yesVirus Genes, 1995
Aphthoviruses are an important group of animal pathogens. A combination of genetic and structural studies has revealed one of the main principles governing their evolution: severe limitations to variation imposed by functional and structural constraints, in conjunction with high mutation and recombination rates operating during genome replication ...

Major Changes in Plastid Protein Import and the Origin of the Chloroplastida

open access: yesiScience, 2020
Summary: Core components of plastid protein import and the principle of using N-terminal targeting sequences are conserved across the Archaeplastida, but lineage-specific differences exist.

Microbial Community Structure Driven by a Volcanic Gradient in Glaciers of the Antarctic Archipelago South Shetland

open access: yesMicroorganisms, 2021
It has been demonstrated that the englacial ecosystem in volcanic environments is inhabited by active bacteria. To know whether this result could be extrapolated to other Antarctic glaciers and to study the populations of microeukaryotes in addition to ...

DNA Polymerases Engineered by Directed Evolution to Incorporate Nonstandard Nucleotides

open access: yesFrontiers in Microbiology, 2014
DNA polymerases have evolved for billions of years to accept natural nucleoside triphosphate substrates with high fidelity and to exclude closely related structures, such as the analogous ribonucleoside triphosphates. However, polymerases that can accept
