A parsimonay analysis of eukaryotic small subunit ribosomal RNA (″18 S″) sequences [PDF]

open access: yesArchives Internationales de Physiologie, de Biochimie et de Biophysique, 1993
Using the principles of Felsenstein's DNA parsimony analysis program (package PHYLIP 3.2), a program with the capacity to handle data sets of the magnitude of ss rRNA has been developed. With this program we applied an heuristic approach to 83 s rRNA sequences from the Antwerp data bank, compared along 4230 positions of their alignment.

Molecular evidence that phoronids are a subtaxon of brachiopods (Brachiopoda: Phoronata) and that genetic divergence of metazoan phyla began long before the early Cambrian [PDF]

open access: yes, 2005
Concatenated SSU (18S) and partial LSU (28S) sequences (~2 kb) from 12 ingroup taxa, comprising 2 phoronids, 2 members of each of the craniid, discinid, and lingulid inarticulate brachiopod lineages, and 4 rhynchonellate, articulate brachiopods (2 ...

An RNA-binding complex involved in ribosome biogenesis contains a protein with homology to tRNA CCA-adding enzyme. [PDF]

open access: yesPLoS Biology, 2013
A multitude of proteins and small nucleolar RNAs transiently associate with eukaryotic ribosomal RNAs to direct their modification and processing and the assembly of ribosomal proteins. Utp22 and Rrp7, two interacting proteins with no recognizable domain,

Nucleotide sequence of the 5′-and 3′-domains for rabbit 18S ribosomal RNA [PDF]

open access: yesNucleic Acids Research, 1982
By direct RNA sequence analysis we have determined the primary structures of both the 5' and 3' domains for rabbit 18S ribosomal RNA. Purified 18S rRNA was labeled in vitro at either its 5' or 3' terminus with 32P, base-specifically fragmented enzymatically and chemically, and the resulting fragments electrophoretically fractionated by size in adjacent

The human Imp3 and Imp4 proteins form a ternary complex with hMpp10, which only interacts with the U3 snoRNA in 60-80S ribonucleoprotein complexes [PDF]

open access: yes, 2003
Ribosome biogenesis requires a vast number of trans-acting factors many of which are required for the chemical modification and processing of the pre-rRNA component.

Selection of Reference Genes for RT-qPCR Analysis Under Intrinsic Conditions in the Hawthorn Spider Mite, Amphitetranychus viennensis (Acarina: Tetranychidae)

open access: yesFrontiers in Physiology, 2019
Hawthorn spider mite, Amphitetranychus viennensis Zacher, is one of the most devastating pests of deciduous fruit trees. The overall goal of this research is to develop a standardized protocol for real-time quantitative reverse transcription PCR (RT-qPCR)

Exploring valid reference genes for quantitative real-time PCR analysis in Sesamia inferens (Lepidoptera: Noctuidae). [PDF]

open access: yesPLoS ONE, 2015
The pink stem borer, Sesamia inferens, which is endemic in China and other parts of Asia, is a major pest of rice and causes significant yield loss in this host plant. Very few studies have addressed gene expression in S. inferens. Quantitative real-time

Genome-wide CRISPR screens identify noncanonical translation factor eIF2A as an enhancer of SARS-CoV-2 programmed −1 ribosomal frameshifting

open access: yesCell Reports, 2023
Summary: Many positive-strand RNA viruses, including all known coronaviruses, employ programmed −1 ribosomal frameshifting (−1 PRF) to regulate the translation of polycistronic viral RNAs.

Nucleotide sequence and evolution of the 18S ribosomal RNA gene in maize mitochondria [PDF]

open access: yesNucleic Acids Research, 1984
The nucleotide sequence of the gene coding for the 18S ribosomal RNA of maize mitochondria has been determined and a model for the secondary structure is proposed. Dot matrix analysis has been used to compare the extent and distribution of sequence similarities of the entire maize mitochondrial 18S rRNA sequence with that of 15 other small subunit rRNA
