Conservation of tRNA and rRNA 5-methylcytosine in the kingdom Plantae.

ABSTRACT:

Background

Post-transcriptional methylation of RNA cytosine residues to 5-methylcytosine (m(5)C) is an important modification that regulates RNA metabolism and occurs in both eukaryotes and prokaryotes. Yet, to date, no transcriptome-wide identification of m(5)C sites has been undertaken in plants. Plants provide a unique comparative system for investigating the origin and evolution of m(5)C as they contain three different genomes, the nucleus, mitochondria and chloroplast. Here we use bisulfite conversion of RNA combined with high-throughput IIlumina sequencing (RBS-seq) to identify single-nucleotide resolution of m(5)C sites in non-coding ribosomal RNAs and transfer RNAs of all three sub-cellular transcriptomes across six diverse species that included, the single-celled algae Nan
