Ribosomal DNA localization on Lathyrus species chromosomes by FISH

Journal of Genetic Engineering and Biotechnology, 2020
Background Fluorescence In Situ Hybridization (FISH) played an essential role to locate the ribosomal RNA genes on the chromosomes that offered a new tool to study the chromosome structure and evolution in plant. The 45S and 5S rRNA genes are independent

Molecular interactions between the constituents of small ribosomal subunit [PDF]

arXiv, 2012
Availability of high-resolution crystal structures of ribosomal subunits of different species opens a route to investigate about molecular interactions between its constituents and stabilization strategy. Structural analysis of the small ribosomal subunit shows that primary binder proteins are mainly employed in stabilizing the folded ribosomal RNA by ...

Genetic and epigenetic variation in 5S ribosomal RNA genes reveals genome dynamics in Arabidopsis thaliana

Nucleic Acids Research, 2018
Organized in tandem repeat arrays in most eukaryotes and transcribed by RNA polymerase III, expression of 5S rRNA genes is under epigenetic control. To unveil mechanisms of transcriptional regulation, we obtained here in depth sequence information on 5S ...

Warming is Associated With More Encoded Antimicrobial Resistance Genes and Transcriptions Within Five Drug Classes in Soil Bacteria: A Case Study and Synthesis

Environmental Microbiology, Volume 27, Issue 4, April 2025.
We found a positive relationship between reported optimal temperature and the number of encoded AMR genes in published soil bacterial genomes. We also observed increased AMR transcription in soil transcriptomes undergoing experimental warming and drying in a natural ecosystem. Warming effects varied by drug class. ABSTRACT The effect of warming on anti‐

Symportin 1 chaperones 5S RNP assembly during ribosome biogenesis by occupying an essential rRNA-binding site [PDF]

, 2015
During 60S biogenesis, mature 5S RNP consisting of 5S RNA, RpL5 and RpL11, assembles into a pre-60S particle, where docking relies on RpL11 interacting with helix 84 (H84) of the 25S RNA.

Higher-order organisation of extremely amplified, potentially functional and massively methylated 5S rDNA in European pikes (Esox sp.)

BMC Genomics, 2017
Background Pikes represent an important genus (Esox) harbouring a pre-duplication karyotype (2n = 2x = 50) of economically important salmonid pseudopolyploids.

Fluctuations in protein synthesis from a single RNA template: stochastic kinetics of ribosomes [PDF]

, 2008
Proteins are polymerized by cyclic machines called ribosome which use their messenger RNA (mRNA) track also as the corresponding template and the process is called translation. We explore, in depth and detail, the stochastic nature of the translation.

Physical modeling of ribosomes along messenger RNA: estimating kinetic parameters from ribosome profiling experiments using a ballistic model [PDF]

arXiv, 2022
Gene expression consists in the synthesis of proteins from the information encoded on DNA. One of the two main steps of gene expression is the translation of messenger RNA (mRNA) into polypeptide sequences of amino acids. Here, by taking into account mRNA degradation, we model the motion of ribosomes along mRNA with a ballistic model where particles ...

Deciphering recent transposition patterns in plants through comparison of 811 genome assemblies

Plant Biotechnology Journal, Volume 23, Issue 4, Page 1121-1132, April 2025.
Summary Transposable elements (TEs) are significant drivers of genome evolution, yet their recent dynamics and impacts within and among species, as well as the roles of host genes and non‐coding RNAs in the transposition process, remain elusive. With advancements in large‐scale pan‐genome sequencing and the development of open data sharing, large‐scale

Fluorescent protein tagging confirms the presence of ribosomal proteins atDrosophilapolytene chromosomes [PDF]

, 2013
\ud \ud Most ribosomal proteins (RPs) are stoichiometrically incorporated into ribosomal subunits and play essential roles in ribosome biogenesis and function.
