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.

RNA Interference Mechanisms and Applications in Plant Pathology.
Annual Review of Phytopathology, 2018The origin of RNA interference (RNAi), the cell sentinel system widely shared among eukaryotes that recognizes RNAs and specifically degrades or prevents their translation in cells, is suggested to predate the last eukaryote common ancestor ( 138 ).

The small RNAs in plant immunity
Hereditas (Beijing), 2012Small RNAs are involved in a multitude of biological processes in plants. Based on their origins and precursor structures, small RNAs can be divided into two major classes: microRNAs (miRNAs) and small interference RNAs (siRNAs). Small RNAs are typically 21-24 nucleotide (nt) long, and differ in both biogenesis and biological function.

In Vitro Cellular & Developmental Biology - Plant, 2005 Abstract The notion that the introduction of alien RNA into an organism can cause the silencing of endogenous genes and transgenes came to light in plants during the last decades of the 20th century. It was based on revealing virus-induced gene silencing (VIGS) and on the protection against pathogenic viruses by pre-infection with less pathogenic plant

We have recently shown that although pre-mRNA splicing in plants shares some features in common with splicing in vertebrates, there are some crucial differences. In plants there is a requirement for a general enrichment for A+U within the intron and there is no requirement for a 3 ' polypyrimidine tract (Goodall and Filipowicz, 1989).

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.

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 ...

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 ...

Advances in imaging RNA in plants
Trends in Plant Science, 2010Increasing evidence shows that many RNAs are targeted to specific locations within cells, and that RNA-processing pathways occur in association with specific subcellular structures. Compartmentation of mRNA translation and RNA processing helps to assemble large RNA-protein complexes, while RNA targeting allows local protein synthesis and the asymmetric

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.
