Archaeal diversity in deep-sea sediments estimated by means of different Terminal-Restriction Fragment Length Polymorphisms (T-RFLP) protocols [PDF]

open access: yes, 2009
Despite the increasing recognition of the quantitative importance of Archaea in all marine systems, the protocols for a rapid estimate of Archaeal diversity patterns in deep-sea sediments have been only poorly tested yet.

Fused eco29kIR- and M genes coding for a fully functional hybrid polypeptide as a model of molecular evolution of restriction-modification systems

open access: yesBMC Evolutionary Biology, 2011
Background The discovery of restriction endonucleases and modification DNA methyltransferases, key instruments of genetic engineering, opened a new era of molecular biology through development of the recombinant DNA technology.

Characterization of Ascaris from Ecuador and Zanzibar [PDF]

open access: yes, 2014
To shed light on the epidemiology of ascariasis in Ecuador and Zanzibar, 177 adult worms retrieved by chemo-expulsion from either people or pigs were collected, measured and subjected to polymerase chain reaction-restriction fragment length polymorphism (

Restriction site heteroplasmy in the mitochondrial DNA of Brycon opalinus (Cuvier, 1819) (Characiformes, Characidae, Bryconiae)

open access: yesBrazilian Journal of Medical and Biological Research, 2004
Homoplasmy is a feature usually found in the mtDNA of higher animal taxa. On the other hand, the presence of two classes of mtDNA in the same cell or organism is rare and may appear in length or site variation.

Genotyping by Sequencing Advancements in Barley

open access: yesFrontiers in Plant Science, 2022
Barley is considered an ideal crop to study cereal genetics due to its close relationship with wheat and diploid ancestral genome. It plays a crucial role in reducing risks to global food security posed by climate change. Genetic variations in the traits

A simple method for the genetic identification of commercially important species in the Opisthonema genus Gill, 1861 in the southern Gulf of California

open access: yesCiencias Marinas, 2020
The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique was used to identify 3 species in the genus Opisthonema (Opisthonema bulleri, Opisthonema medirastre, and Opisthonema libertate) in the southern Gulf of ...

Pathological phenotypes and in vivo DNA cleavage by unrestrained activity of a phosphorothioate-based restriction system in Salmonella [PDF]

open access: yes, 2014
Prokaryotes protect their genomes from foreign DNA with a diversity of defence mechanisms, including a widespread restriction–modification (R–M) system involving phosphorothioate (PT) modification of the DNA backbone. Unlike classical R–M systems, highly

Internuclear gene silencing in Phytophthora infestans is established through chromatin remodelling [PDF]

open access: yes, 2008
In the plant pathogen Phytophthora infestans, nuclear integration of inf1 transgenic DNA sequences results in internuclear gene silencing of inf1. Although silencing is regulated at the transcriptional level, it also affects transcription from other ...
