THE SYNTHESIS OF 5S RIBOSOMAL RNA DURING POLLEN DEVELOPMENT [PDF]

Development, Growth and Differentiation, 1975
Tradescantia paludosa 5S ribosomal RNA (rRNA) has been characterized with respect to its base composition and relative electrophoretic mobility in comparison with that of E. coli. The period of 5S rRNA synthesis during pollen grain development was determined by pulse labeling the RNA synthesized during a 24 hr period of development with 32 P and then ...

SSB-1 of the yeast Saccharomyces cerevisiae is a nucleolar-specific, silver-binding protein that is associated with the snR10 and snR11 small nuclear RNAs [PDF]

, 1990
SSB-1, the yeast single-strand RNA-binding protein, is demonstrated to be a yeast nucleolar-specific, silver-binding protein. In double-label immunofluorescence microscopy experiments antibodies to two other nucleolar proteins, RNA Pol I 190-kD and ...

Overexpression of a Brix Domain-Containing Ribosome Biogenesis Factor ARPF2 and its Interactor ARRS1 Causes Morphological Changes and Lifespan Extension in Arabidopsis thaliana

Frontiers in Plant Science, 2018
The Brix domain is a conserved domain in several proteins involved in ribosome biogenesis in yeast and animals. In the Arabidopsis genome, six Brix domain-containing proteins are encoded; however, their molecular functions have not been fully ...

Modeling of Ribosome Dynamics on a ds-mRNA under an External Load [PDF]

J. Chem. Phys. 145, 025101 (2016), 2016
Protein molecules in cells are synthesized by macromolecular machines called ribosomes. According to recent experimental data, we reduce the complexity of the ribosome and propose a model to express its activity in six main states. Using our model, we study the translation rate in different biological relevant situations in the presence of external ...

In situ quantification of ribosome number by electron tomography

Journal of Microscopy, EarlyView.
Abstract Ribosomes, discovered in 1955 by George Palade, were initially described as small cytoplasmic particles preferentially associated with the endoplasmic reticulum (ER). Over the years, extensive research has focused on both the structure and function of ribosomes.

Cryo-Electron Microscopy Visualization of a Large Insertion in the 5S ribosomal RNA of the Extremely Halophilic Archaeon Halococcus morrhuae

bioRxiv, 2020
The extreme halophile Halococcus morrhuae (ATCC® 17082) contains a 108-nucleotide insertion in its 5S rRNA. Large rRNA expansions in Archaea are rare. This one almost doubles the length of the 5S rRNA.

Oocyte and somatic 5S ribosomal RNA and 5S RNA encoding genes in Xenopus tropicalis

Nucleic Acids Research, 1988
We have investigated the structure of oocyte and somatic 5S ribosomal RNA and of 5S RNA encoding genes in Xenopus tropicalis. The sequences of the two 5S RNA families differ in four positions, but only one of these substitutions, a C to U transition in position 79 within the internal control region of the corresponding 5S RNA encoding genes, is a ...

A telomere‐to‐telomere gap‐free assembly integrating multi‐omics uncovers the genetic mechanism of fruit quality and important agronomic trait associations in pomegranate

Plant Biotechnology Journal, EarlyView.
Summary Pomegranate is an important perennial fruit tree distributed worldwide. Reference genomes with gaps and limit gene identification controlling important agronomic traits hinder its functional genomics and genetic improvements. Here, we reported a telomere‐to‐telomere (T2T) gap‐free genome assembly of the distinctive cultivar ‘Moshiliu’.

Transcriptionally inactive oocyte-type 5S RNA genes of Xenopus laevis are complexed with TFIIIA in vitro [PDF]

, 1987
An extract from whole oocytes of Xenopus laevis was shown to transcribe somatic-type 5S RNA genes approximately 100-fold more efficiently than oocyte-type 5S RNA genes.

Long non-coding RNAs as a source of new peptides [PDF]

, 2014
Deep transcriptome sequencing has revealed the existence of many transcripts that lack long or conserved open reading frames and which have been termed long non-coding RNAs (lncRNAs). Despite the existence of several well-characterized lncRNAs that play roles in the regulation of gene expression, the vast majority of them do not yet have a known ...
