TaxCollector: Modifying Current 16S rRNA Databases for the Rapid Classification at Six Taxonomic Levels

open access: yesDiversity, 2010
The high level of conservation of 16S ribosomal RNA gene (16S rRNA) in all Prokaryotes makes this gene an ideal tool for the rapid identification and classification of these microorganisms. Databases such as the Ribosomal Database Project II (RDP-II) and

Measurement of the rates of synthesis of three components of ribosomes of Mycobacterium fortuitum: a theoretical approach to qRT-PCR experimentation. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Except for the ribosomal protein L12 (rplL), ribosomal proteins are present as one copy per ribosome; L12 (rplL) is unusual because it is present as four copies per ribosome.

Crinoid phylogeny: a preliminary analysis (Echinodermata: Crinoidea) [PDF]

open access: yes, 2004
We describe the first molecular and morphological analysis of extant crinoid high-level inter-relationships. Nuclear and mitochondrial gene sequences and a cladistically coded matrix of 30 morphological characters are presented, and analysed by ...

Probing complex RNA structures by mechanical force

open access: yes, 2003
RNA secondary structures of increasing complexity are probed combining single molecule stretching experiments and stochastic unfolding/refolding simulations. We find that force-induced unfolding pathways cannot usually be interpretated by solely invoking

Identification and Phylogenetic Analysis of Bacterial Isolates from Litopenaeus vannamei Shrimp Culture System and Gut Environment Based on 16SrRNA Gene Sequence Data

open access: yesMicrobiology Indonesia, 2010
Selected bacterial isolates from a Litopenaeus vannamei shrimp culture system and gut environment were assessed using 16S rRNA gene sequencing method to identify their identity and to construct their phylogenetic relationship.

Louse (Insecta : Phthiraptera) mitochondrial 12S rRNA secondary structure is highly variable [PDF]

open access: yes, 2002
Lice are ectoparasitic insects hosted by birds and mammals. Mitochondrial 12S rRNA sequences obtained from lice show considerable length variation and are very difficult to align.

Novel insights into the Thaumarchaeota in the deepest oceans: their metabolism and potential adaptation mechanisms [PDF]

open access: yes, 2020
Background: Marine Group I (MGI) Thaumarchaeota, which play key roles in the global biogeochemical cycling of nitrogen and carbon (ammonia oxidizers), thrive in the aphotic deep sea with massive populations.
