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 ...

rDNAmine: A New Tool for the Analysis of Long Repetitive Sequences

Yeast, Volume 43, Issue 4, Page 170-183, July 2026.
This work introduces a novel approach for analysing long repetitive genomic sequences, combining a method to isolate large DNA molecules from individual chromosomes. We also describe the bioinformatics tool rDNAmine, which enables the isolation of long‐repeat sequences from reads obtained using the Oxford Nanopore method, as well as their preliminary ...

PAPD5, a noncanonical poly(A) polymerase with an unusual RNA-binding motif [PDF]

, 2011
PAPD5 is one of the seven members of the family of noncanonical poly(A) polymerases in human cells. PAPD5 was shown to polyadenylate aberrant pre-ribosomal RNAs in vivo, similar to degradation-mediating polyadenylation by the noncanonical poly(A ...

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

Pentatricopeptide repeat proteins in crops: Advances in functional mechanisms and breeding applications

Journal of Integrative Plant Biology, Volume 68, Issue 7, Page 1973-2000, July 2026.
Pentatricopeptide repeat proteins coordinate nucleus‐organelle communication by modulating RNA metabolism within chloroplasts and mitochondria. This review highlights how they control critical processes like photosynthesis, seed development, fertility restoration, and stress survival in crops, and explores their potential as programmable tools for RNA ...

A new RNA-RNA crosslinking reagent and its application to ribosomal 5S RNA

, 1978
The synthesis of a new RNA specific bifunctional crosslinking reagent, 1.4-phenyl-diglyoxal, is described which reacts exclusively with guanosines.The properties of the crosslinked products enabled us to develop a straightforward method for identifying ...

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.

Ribozyme für die RNA‐katalysierte Methylierung und Markierung von RNA

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
Ribozyme sind vielseitige Werkzeuge für die präzise Modifikation von RNA. Das Reaktionsspektrum in‐vitro‐selektierter Ribozyme reicht vom Einbau funktioneller Gruppen und Fluorophoren bis zu natürlichen RNA‐Methylierungen. Dieser Übersichtsartikel präsentiert Cofaktor‐abhängige Ribozyme für die positionsgenaue Markierung und Modifikation von RNA ...
