Reproductive Isolation Between Taxonomically Controversial Forms of the Gray Voles (Microtus, Rodentia; Arvicolinae): Cytological Mechanisms and Taxonomical Implications

open access: yesFrontiers in Genetics, 2021
The formation of hybrid sterility is an important stage of speciation. The voles of the genus Microtus, which is the most speciose genus of rodents, provide a good model for studying the cytological mechanisms of hybrid sterility.

Recombination in enteroviruses is a biphasic replicative process involving the generation of greater-than genome length 'imprecise' intermediates [PDF]

open access: yes, 2014
Recombination in enteroviruses provides an evolutionary mechanism for acquiring extensive regions of novel sequence, is suggested to have a role in genotype diversity and is known to have been key to the emergence of novel neuropathogenic variants of ...

SARS-CoV-2: from its discovery to genome structure, transcription, and replication

open access: yesCell & Bioscience, 2021
SARS-CoV-2 is an extremely contagious respiratory virus causing adult atypical pneumonia COVID-19 with severe acute respiratory syndrome (SARS). SARS-CoV-2 has a single-stranded, positive-sense RNA (+RNA) genome of ~ 29.9 kb and exhibits significant ...

Two Targets, One Hit: new Anticancer Therapeutics to Prevent Tumorigenesis Without Cardiotoxicity

open access: yesFrontiers in Pharmacology, 2021
A serious adverse effect of cancer therapies is cardiovascular toxicity, which significantly limits the widespread use of antineoplastic agents. The promising new field of cardio-oncology offers the identification of potent anti-cancer therapeutics that ...

Recombination in RNA

open access: yesCell, 1982
The aphthovirus genome consists of a single molecule of single-stranded RNA that encodes all the virus-induced proteins. We isolated recombinant aphthoviruses from cells simultaneously infected with temperature-sensitive mutants of two different subtype strains.

Histone H3 Lysine 56 Acetylation Is Required for Formation of Normal Levels of Meiotic DNA Breaks in S. cerevisiae

open access: yesFrontiers in Cell and Developmental Biology, 2020
Meiotic recombination is initiated by Spo11-catalyzed DNA double-strand breaks (DSBs) that are promoted by histone modifications and histone modifying enzymes. Herein we investigated the role of histone H3 lysine 56 acetylation (H3K56ac) located near the

Recombination and Replication [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2014
The links between recombination and replication have been appreciated for decades and it is now generally accepted that these two fundamental aspects of DNA metabolism are inseparable: Homologous recombination is essential for completion of DNA replication and vice versa.

Bayesian modeling of recombination events in bacterial populations [PDF]

open access: yes, 2008
Background: We consider the discovery of recombinant segments jointly with their origins within multilocus DNA sequences from bacteria representing heterogeneous populations of fairly closely related species.

Poxvirus Recombination

open access: yesPathogens, 2022
Genetic recombination is used as a tool for modifying the composition of poxvirus genomes in both discovery and applied research. This review documents the history behind the development of these tools as well as what has been learned about the processes that catalyze virus recombination and the links between it and DNA replication and repair.

Recombination in Wolbachia [PDF]

open access: yesCurrent Biology, 2001
Wolbachia are widely distributed intracellular bacteria that cause a number of reproductive alterations in their eukaryotic hosts. Such alterations include the induction of parthenogenesis, feminization, cytoplasmic incompatibility, and male killing [1-11].
