The 23S Ribosomal RNA From Pyrococcus furiosus Is Circularly Permuted

open access: yesFrontiers in Microbiology, 2020
Synthesis and assembly of ribosomal components are fundamental cellular processes and generally well-conserved within the main groups of organisms. Yet, provocative variations to the general schemes exist. We have discovered an unusual processing pathway

Autophagy regulates rRNA synthesis

open access: yesNucleus, 2022
Autophagy has emerged as a key regulator of cell metabolism. Recently, we have demonstrated that autophagy is involved in RNA metabolism by regulating ribosomal RNA (rRNA) synthesis.

Recognition of Ribosomal RNA Sites in DNA, I. Analysis of the E. coli System [PDF]

open access: yes, 1965
The evidence recently presented of specific hybridization between bacterial ribosomal RNA and homologous DNA1-3 has indicated the possibility of a biochemical approach to the problem of the identification of ribosomal RNA sites in DNA.

Conformational switches control early maturation of the eukaryotic small ribosomal subunit

open access: yeseLife, 2019
Eukaryotic ribosome biogenesis is initiated with the transcription of pre-ribosomal RNA at the 5’ external transcribed spacer, which directs the early association of assembly factors but is absent from the mature ribosome.

The complete chloroplast genome of Juniperus squamata (Cupressaceae), a shrubby conifer from Asian Mountains

open access: yesMitochondrial DNA. Part B. Resources, 2019
The complete chloroplast genome of Juniperus squamata, a shrubby conifer of ornamental value, is determined in this study. The complete chloroplast genome size is 127,792 bp in length.

Yeast Rrp8p, a novel methyltransferase responsible for m1A 645 base modification of 25S rRNA [PDF]

open access: yes, 2012
Ribosomal RNA undergoes various modifications to optimize ribosomal structure and expand the topological potential of RNA. The most common nucleotide modifications in ribosomal RNA (rRNA) are pseudouridylations and 2'-O methylations (Nm), performed by H ...

FIERY1 promotes microRNA accumulation by suppressing rRNA-derived small interfering RNAs in Arabidopsis

open access: yesNature Communications, 2019
Arabidopsis AGO1 binds both microRNA (miRNA) and endogenous small interfering RNA (siRNA). Here the authors show that 5′−3′ RNA degradation suppresses siRNA biogenesis from ribosomal RNA to prevent overloading of AGO1 with ribosomal siRNA and maintain ...

Ribosomal RNA regulates chromosome clustering during mitosis

open access: yesCell Discovery, 2022
Noncoding RNAs are known to associate with mitotic chromosomes, but the identities and functions of chromosome-associated RNAs in mitosis remain elusive. Here, we show that rRNA species associate with condensed chromosomes during mitosis.

A Ribosome Without RNA [PDF]

open access: yesFrontiers in Ecology and Evolution, 2015
It was Francis Crick who first asked why the ribosome contains so much RNA, and discussed the implications of this for the direct flow of genetic information from DNA to protein. Remarkable advances in our understanding of the ribosome and protein synthesis, including the recent publication of two mammalian mitochondrial ribosome structures, have shed ...
