Annual Review of Plant Biology, 2021
Plants have an extraordinary diversity of transcription machineries, including five nuclear DNA-dependent RNA polymerases. Four of these enzymes are dedicated to the production of long noncoding RNAs (lncRNAs), which are ribonucleic acids with functions independent of their protein-coding potential.

Transfer RNA-derived small RNAs in plants
Science China Life Sciences, 2017Rather than random degradation products, the 18 to 40 nucleotides (nt) transfer RNA-derived small RNAs (tsRNAs) are RNA species generated specifically from pre-RNAs or mature tRNAs in archaea, bacteria and eukaryotes. Recent studies from animal systems have shown that tsRNAs are important non-coding RNAs that regulate gene expression at the ...

RNA Editing in Plant Mitochondria
Science, 1989Comparative sequence analysis of genomic and complementary DNA clones from several mitochondrial genes in the higher plant Oenothera revealed nucleotide sequence divergences between the genomic and the messenger RNA-derived sequences.

Isolation of plant mitochondrial RNA
1986Publisher Summary This chapter discusses the methods for the isolation of plant mitochondrial RNA (mt RNA). The analysis of plant mitochondrial transcripts necessitates the preparation of RNA isolated from mitochondria rather than total RNA. The procedures required to separate plant mitochondria from other subcellular components are time consuming ...

RNA metabolism in plant mitochondria
Trends in Plant Science, 2014Mitochondria are essential for the eukaryotic cell and are derived from the endosymbiosis of an α-proteobacterial ancestor. Compared to other eukaryotes, RNA metabolism in plant mitochondria is complex and combines bacterial-like traits with novel features that evolved in the host cell.

Current Opinion in Microbiology, 2003
RNA viruses are the most common viruses of plants, and the evolution of these viruses has been studied both experimentally and phylogenetically. The basic molecular mechanisms for plant virus evolution are similar to those of other viruses, with some notable exceptions. Recent advances include new insights into the origins of plant viruses, analyses of

Ribosomal RNA precursors in plants
Journal of Molecular Biology, 1970Abstract A high molecular weight, rapidly-labelled ribosomal RNA precursor in the pearoot tip and in artichoke-tuber tissue is described. It has a molecular weight, determined by polyacrylamide-gel electrophoresis, of about 2.3 × 10 6 daltons. The pea precursor RNA consists of two components which can just be distinguished by gel electrophoresis ...

Messenger RNA Modifications in Plants
Trends in Plant Science, 2019Over 160 distinct RNA modifications are known and collectively termed the epitranscriptome. Some of these modifications have been discovered in mRNA, uncovering a new layer of gene regulation. Transcriptome-wide mapping of epitranscriptomic codes and the discovery of their writers, erasers, and readers that dynamically install, remove, and interpret ...

Ribosomal RNA synthesis in plants
Journal of Molecular Biology, 1970Abstract The cytoplasmic ribosomal RNA's (of molecular weight 1.3 × 106 and 0.7 × 106 daltons) of higher plants arise by the selective cleavage of larger precursor molecules. The main precursor RNA species in carrot (Daucus carota) have been tentatively characterized by polyacrylamide-gel electrophoresis as having molecular weights of 2.8 × 106, 2.2 ×

The correct interpretation — that this RNA played the role of a messenger between the inserted phage DNA and the appearance of viral proteins in the bacterial cell — was provided by Jacob and Monod. Nevertheless, understanding regulation of important eukaryotic proteins requires that messenger RNAs (mRNAs) be isolated from higher organisms.
