摘要
Background: Small nucleolar RNAs (snoRNAs) are one of the most ancient families amongst non-蛋白質-coding RNAs. They are ubiquitous in Archaea and Eukarya but absent in 細菌. Their main function is to target chemical modifications of ribosomal RNAs. They fall into two classes, box C/D snoRNAs and box H/ACA snoRNAs, which are clearly distinguished by conserved sequence motifs and the type of chemical modification that they govern. Similarly to microRNAs, snoRNAs appear in distinct families of homologs that affect homologous targets. In animals, snoRNAs and their 演化 have been studied in much detail. In plants, however, their 演化 has attracted comparably little attention. Results: In order to chart the 系統發育 distribution of individual snoRNA families in plants, we applied a sophisticated approach fo
