Plants have remarkable developmental plasticity, and the same genotype can result in different phenotypes depending on environmental variation. Indeed, abiotic stresses or biotic interactions affect organogenesis and post-embryonic growth and significantly affect gene regulation.

Plant Mitochondrial RNA Editing
Journal of Molecular Evolution, 1999RNA editing affects messenger RNAs and transfer RNAs in plant mitochondria by site-specific exchange of cytidine and uridine bases in both seed and nonseed plants. Distribution of the phenomenon among bryophytes has been unclear since RNA editing has been detected in some but not all liverworts and mosses.

Optimal sampling procedures for sampling plant tissue for RNA extractions are outlined in this chapter. To extract RNA, kits supplied from biotechnology companies are appropriate, but some procedures will not work with particular plant tissues. Two alternative methods are supplied for troublesome material.

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 ...
