Small nucleolar RNA SNORD15 C/D family function in directing site-specific 2'-O-methylation of substrate RNAs. U15 is predicted to guide the 2'O-ribose methylation of 28S ribosomal RNA (rRNA) residue A3764. In humans there are two closely related copies of the U15 snoRNA (called SNORD15A and SNORD15B). They are both encoded in the introns of the ribosomal protein S3. In "Xenopus laevis" it is located within the introns of ribosomal protein S1 snoR75 from "Arabidopsis thaliana" and homologues in rice "Oryza sativa" and other plants are alternatively known as U15, and, despite a significantly shorter sequence length, appear to be related.

Scirpophaga gilviberbis on "Oryza" species, including "Oryza sativa". Scirpophaga gilviberbis Scirpophaga gilviberbis is a moth in the Crambidae family. It was described by Zeller in 1863. It is found on the Comoros and in the Democratic Republic of Congo, Kenya, South Africa, Zambia, India, Indonesia (Java, Sulawesi), Myanmar, Singapore, Thailand and Vietnam. The wingspan is 20–22 mm for males and 23–35 mm for females. The forewings of the males are ochreous with some fuscous scales. The hindwings are white, except for the costal area and the apex which are ochreous. Females have white fore- and hindwings. The anal tuft is whitish grey
