Identification of the gene encoding the 5S ribosomal RNA maturase in Bacillus subtilis: mature 5S rRNA is dispensable for ribosome function.

RNA: A publication of the RNA Society, 2001
Over 25 years ago, Pace and coworkers described an activity called RNase M5 in Bacillus subtilis cell extracts responsible for 5S ribosomal RNA maturation (Sogin & Pace, Nature, 1974, 252:598-600).

Isolation of high quality RNA from soil-grown Ilex paraguariensis roots suitable for next-generation sequencing and gene expression analyses [PDF]

, 2017
Extraction of high quality RNA is a prerequisite for downstream application in functional genomics analyses. However, the extraction and purification of pure nucleic acids from root tissues is generally difficult due to the high concentration of ...

In situ quantification of ribosome number by electron tomography

Journal of Microscopy, Volume 299, Issue 3, Page 212-227, September 2025.
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.

A robust machine learning model based on ribosomal‐subunit‐derived piRNAs for diagnostic potential of nonsmall cell lung cancer across multicentre, large‐scale of sequencing data

Clinical and Translational Medicine, Volume 15, Issue 8, August 2025.
NSCLC lacks robust noninvasive biomarkers. We curated 2050 invasive and noninvasive samples, integrating public and in‐house plasma/exosome data. A machine learning model using five tumour‐specific piRNA signatures formed the piRNA‐Based Tumour Probability Index (pi‐TPI), achieving AUC values up to .96, demonstrating strong potential for NSCLC ...

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

Mirror-Image 5S Ribonucleoprotein Complexes [PDF]

, 2020
After realizing mirror-image genetic replication, transcription, and reverse transcription, the biggest challenge in establishing a mirror-image version of the central dogma is to build a mirror-image ribosome-based translation machine.

Non‐coding RNAs in plant stress responses: molecular insights and agricultural applications

Plant Biotechnology Journal, Volume 23, Issue 8, Page 3195-3233, August 2025.
Summary Non‐coding RNAs (ncRNAs) have emerged as crucial regulators in plant responses to environmental stress, orchestrating complex networks that finetune gene expression under both abiotic and biotic challenges. To elucidate this intricate ncRNA crosstalk, this review comprehensively summarizes recent advances in understanding the mechanisms of key ...
