These small nucleolar RNAs (snoRNAs) are modifying RNAs and usually located in the nucleolus of the eukaryotic cell which is a major site of snRNA biogenesis. These two snoRNAs R87 and Z107 were identified in the plant Arabidopsis thaliana[1] and rice Oryza sativa[2] respectively. These related snoRNAs are predicted to belong to the C/D box class of snoRNAs which contain the conserved sequence motifs known as the C box (UGAUGA) and the D box (CUGA). Most of the members of the box C/D family function in directing site-specific 2'-O-methylation of substrate RNAs.[3] References1. ^{{cite journal |vauthors=Barneche F, Gaspin C, Guyot R, Echeverría M |title=Identification of 66 box C/D snoRNAs in Arabidopsis thaliana: extensive gene duplications generated multiple isoforms predicting new ribosomal RNA 2'-O-methylation sites |journal=J.
