Catalogue of fungi in China 2. Ramaria from northern China

open access: yesMycology
The species of Ramaria are coralloid-fungi with intricately branched and vividly coloured basidiomata. There are many studies on the genus Ramaria in China, but molecular phylogenetic analysis is rarely employed.

Phylogenetic and phyletic studies of informational genes in genomes highlight existence of a 4 domain of life including giant viruses. [PDF]

open access: yesPLoS ONE, 2010
The discovery of Mimivirus, with its very large genome content, made it possible to identify genes common to the three domains of life (Eukarya, Bacteria and Archaea) and to generate controversial phylogenomic trees congruent with that of ribosomal genes,

Ribosomal protein S3: A multifunctional target of attaching/effacing bacterial pathogens

open access: yesFrontiers in Cellular and Infection Microbiology, 2011
The extraribosomal functions of ribosomal proteins have drawn significant recent attention. Ribosomal Protein S3 (RPS3), a component of the eukaryotic 40S ribosomal subunit, is a multifunctional protein that regulates DNA repair, apoptosis, and the ...

Discontinuous transcription of ribosomal DNA in human cells.

open access: yesPLoS ONE, 2020
Numerous studies show that various genes in all kinds of organisms are transcribed discontinuously, i.e. in short bursts or pulses with periods of inactivity between them.

PCR primers for metazoan nuclear 18S and 28S ribosomal DNA sequences. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Metagenetic analyses, which amplify and sequence target marker DNA regions from environmental samples, are increasingly employed to assess the biodiversity of communities of small organisms. Using this approach, our understanding of microbial

Morphological and molecular identification of filamentous fungi isolated from cosmetic powders

open access: yesBrazilian Archives of Biology and Technology, 2012
Seven fungi were isolated from 50 samples of cosmetic powders. Morphological analyses and ribosomal DNA Internal Transcribed Spacers sequencing were performed which allowed the discrimination of the isolated fungi as Aspergillus fumigatus, Penicillium sp.

Characterization of ribosomal DNA (rDNA) in Drosophila arizonae

open access: yesGenetics and Molecular Biology, 2000
Ribosomal DNA (rDNA) is a multigenic family composed of one or more clusters of repeating units (RU). Each unit consists of highly conserved sequences codifying 18S, 5.8S and 28S rRNA genes intercalated with poorly conserved regulatory sequences between ...

Molecular Evidence of Trichobilharzia Species (Digenea: Schistosomatidae) in the Snails of Lymnaea auricularia from Urmia Suburb, North West Iran

open access: yesIranian Journal of Parasitology, 2016
Background: The present study was carried out to detect the infection of larval stages of Trichobilharzia species in the snail Lymnaea auricularia in northwestern Iran based on DNA analysis. Methods: A total number of 320 snails of L.
